DESCRIPTION
Qsub submits batch jobs to the xxQS_NAMExx queuing system. xxQS_NAMExx supports single- and multiple-node jobs. Command can be a path to a binary or a script (see -b below) which contains the commands to be run by the job using a shell (for example, or Arguments to the command are given as command_args to qsub . If command is handled as a script then it is possible to embed flags in the script. If the first two characters of a script line either match '#$' or are equal to the prefix string defined with the -C option described below, the line is parsed for embedded command flags.

Qsh submits an interactive X-windows session to xxQS_NAMExx. An is brought up from the executing machine with the display directed either to the X-server indicated by the DISPLAY environment variable or as specified with the -display qsh option. Interactive jobs are not spooled if no resource is available to execute them. They are either dispatched to a suitable machine for execution immediately or the user submitting the job is notified by qsh that appropriate resources to execute the job are not available. xterm_args are passed to the executable. Note, however, that the -e and -ls xterm options do not work with qsh .

Qlogin is similar to qsh in that it submits an interactive job to the queuing system. It does not open an window on the X display, but uses the current terminal for user I/O. Usually, qlogin establishes a connection with the remote host, using standard client- and server-side commands. These commands can be configured with the qlogin_daemon (server-side, xxQS_NAMExx telnetd if not set, otherwise something like /usr/sbin/in.telnetd) and qlogin_command (client-side, xxQS_NAMExx telnet if not set, otherwise something like /usr/bin/telnet) parameters in the global and local configuration settings of The client side command is automatically parameterized with the remote host name and port number to which to connect, resulting in an invocation like

    /usr/bin/telnet my_exec_host 2442

for example. Qlogin is invoked exactly like qsh and its jobs can only run on INTERACTIVE queues. Qlogin jobs can only be used if the is running under the root account.

Qrsh is similar to qlogin in that it submits an interactive job to the queuing system. It uses the current terminal for user I/O. Usually, qrsh establishes a connection with the remote host. If no command is given to qrsh, an session is established. The server-side commands used can be configured with the rsh_daemon and rlogin_daemon parameters in the global and local configuration settings of An xxQS_NAMExx rshd or rlogind is used if the parameters are not set. If the parameters are set, they should be set to something like /usr/sbin/in.rshd or /usr/sbin/in.rlogind. On the client-side, the rsh_command and rlogin_command parameters can be set in the global and local configuration settings of If they are not set, special xxQS_NAMExx and binaries delivered with xxQS_NAMExx are used. Use the cluster configuration parameters to integrate mechanisms like ssh or the and facilities supplied with the operating system.

Qrsh jobs can only run in INTERACTIVE queues unless the option -now no is used (see below). They can also only be run, if the is running under the root account.

Qrsh provides an additional useful feature for integrating with interactive tools providing a specific command shell. If the environment variable QRSH_WRAPPER is set when qrsh is invoked, the command interpreter pointed to by QRSH_WRAPPER will be executed to run qrsh commands instead of the users login shell or any shell specified in the qrsh command-line. The options -cwd, -v, -V, and -display only apply to batch jobs.

Qalter can be used to change the attributes of pending jobs. For array jobs with a mix of running and pending tasks (see the -t option below), modification with qalter only affects the pending tasks. Qalter can change most of the characteristics of a job (see the corresponding statements in the OPTIONS section below), including those which were defined as embedded flags in the script file (see above). Some submit options, such as the job script, cannot be changed with I. qalter.

Qresub allows the user to create jobs as copies of existing pending or running jobs. The copied jobs will have exactly the same attributes as the ones from which they were copied, except with a new job ID and with a cleared hold state. The only modification to the copied jobs supported by qresub is assignment of a new hold state with the -h option. This option can be used to first copy a job and then change its attributes via qalter.

Only a manager can use qresub on jobs submitted by another user. Regular users can only use qresub on their own jobs.

For qsub, qsh, qrsh, and qlogin the administrator and the user may define default request files (see which can contain any of the options described below. If an option in a default request file is understood by qsub and qlogin but not by qsh the option is silently ignored if qsh is invoked. Thus you can maintain shared default request files for both qsub and qsh.

A cluster wide default request file may be placed under $xxQS_NAME_Sxx_ROOT/$xxQS_NAME_Sxx_CELL/common/xxqs_name_sxx_request. User private default request files are processed under the locations $HOME/.xxqs_name_sxx_request and $cwd/.xxqs_name_sxx_request. The working directory local default request file has the highest precedence, then the home directory located file and then the cluster global file. The option arguments, the embedded script flags and the options in the default request files are processed in the following order:

    left to right in the script line,
    left to right in the default request files,
    from top to bottom of the script file (qsub only),
    from top to bottom of default request files,
    from left to right of the command line.

In other words, the command line can be used to override the embedded flags and the default request settings. The embedded flags, however, will override the default settings.

Note, that the -clear option can be used to discard any previous settings at any time in a default request file, in the embedded script flags, or in a command-line option. It is, however, not available with qalter.

The options described below can be requested either hard or soft. By default, all requests are considered hard until the -soft option (see below) is encountered. The hard/soft status remains in effect until its counterpart is encountered again. If all the hard requests for a job cannot be met, the job will not be scheduled. Jobs which cannot be run at the present time remain spooled.

OPTIONS

-@ optionfile
    Forces qsub, qrsh, qsh, or qlogin to use the options contained in optionfile. The indicated file may contain all valid options. Comment lines must start with a "#" sign.

-a date_time
    Available for qsub and qalter only.

    Defines or redefines the time and date at which a job is eligible for execution. Date_time conforms to [[CC]]YY]MMDDhhmm[.SS], for the details, please see Date_time in:

    If this option is used with qsub or if a corresponding value is specified in qmon then a parameter named a and the value in the format CCYYMMDDhhmm.SS will be passed to the defined JSV instances (see -jsv option below or find more information concerning JSV in

-ac variable[=value],...
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Adds the given name/value pair(s) to the job's context. Value may be omitted. xxQS_NAMExx appends the given argument to the list of context variables for the job. Multiple -ac, -dc, and -sc options may be given. The order is important here.

    The outcome of the evaluation of all -ac, -dc, and -sc options or corresponding values in qmon is passed to defined JSV instances as parameter with the name ac. (see -jsv option below or find more information concerning JSV in QALTER allows changing this option even while the job executes.

-ar ar_id
    Available for qsub, qalter, qrsh, qsh, or qlogin only.

    Assigns the submitted job to be a part of an existing Advance Reservation. The complete list of existing Advance Reservations can be obtained using the command.

    Note that the -ar option adds implicitly the -w e option if not otherwise requested.

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job however.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name ar. (see -jsv option below or find more information concerning JSV in

-A account_string
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Identifies the account to which the resource consumption of the job should be charged. The account_string should conform to the name definition in M sge_types 1 . In the absence of this parameter xxQS_NAMExx will place the default account string "xxqs_name_sxx" in the accounting record of the job.

    Qalter allows changing this option even while the job executes.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name A. (see -jsv option below or find more information concerning JSV in

-binding [ binding_instance ] binding_strategy
    A job can request a specific processor core binding (processor affinity) with this parameter. This request is neither a hard nor a soft request, it is a hint for the execution host to do this if possible. Please note that the requested binding strategy is not used for resource selection within xxQS_NAMExx. As a result an execution host might be selected where xxQS_NAMExx does not even know the hardware topology and therefore is not able to apply the requested binding.

    To enforce xxQS_NAMExx to select hardware on which the binding can be applied please use the -l switch in combination with the complex attribute m_topology.

    binding_instance is an optional parameter. It might either be env, pe or set depending on which instance should accomplish the job to core binding. If the value for binding_instance is not specified then set will be used.

    env means that the environment variable SGE_BINDING will be exported to the job environment of the job. This variable contains the selected operating system internal processor numbers. They might be more than selected cores in presence of SMT or CMT because each core could be represented by multiple processor identifiers. The processor numbers are space separated.

    pe means that the information about the selected cores appears in the fourth column of the pe_hostfile. Here the logical core and socket numbers are printed (they start at 0 and have no holes) in colon separated pairs (i.e. 0,0:1,0 which means core 0 on socket 0 and core 0 on socket 1). For more information about the $pe_hostfile check

    set (default if nothing else is specified). The binding strategy is applied by xxQS_NAMExx. How this is achieved depends on the underlying hardware architecture of the execution host where the submitted job will be started.

    On Solaris 10 hosts a processor set will be created where the job can exclusively run in. Because of operating system limitations at least one core must remain unbound. This resource could of course used by an unbound job.

    On Linux hosts a processor affinity mask will be set to restrict the job to run exclusively on the selected cores. The operating system allows other unbound processes to use these cores. Please note that on Linux the binding requires a Linux kernel version of 2.6.16 or greater. It might be even possible to use a kernel with lower version number but in that case additional kernel patches have to be applied. The loadcheck tool in the utilbin directory can be used to check if the hosts capabilities. You can also use the -sep in combination with -cb of command to identify if xxQS_NAMExx is able to recognize the hardware topology.

    Possible values for binding_strategy are as follows:

        linear:<amount>[:<socket>,<core>]
        striding:<amount>:<n>[:<socket>,<core>]
        explicit:[<socket>,<core>;...]<socket>,<core>

    For the binding strategy linear and striding there is an optional socket and core pair attached. These denotes the mandatory starting point for the first core to bind on.

    linear means that xxQS_NAMExx tries to bind the job on amount successive cores. If socket and core is omitted then xxQS_NAMExx first allocates successive cores on the first empty socket found. Empty means that there are no jobs bound to the socket by xxQS_NAMExx. If this is not possible or is not sufficient xxQS_NAMExx tries to find (further) cores on the socket with the most unbound cores and so on. If the amount of allocated cores is lower than requested cores, no binding is done for the job. If socket and core is specified then xxQS_NAMExx tries to find amount of empty cores beginning with this starting point. If this is not possible then binding is not done.

    striding means that xxQS_NAMExx tries to find cores with a certain offset. It will select amount of empty cores with a offset of n -1 cores in between. Start point for the search algorithm is socket 0 core 0. As soon as amount cores are found they will be used to do the job binding. If there are not enough empty cores or if correct offset cannot be achieved then there will be no binding done.

    explicit binds the specified sockets and cores that are mentioned in the provided socket/core list. Each socket/core pair has to be specified only once. If a socket/core pair is already in use by a different job the whole binding request will be ignored.

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    If this option or a corresponding value in qmon is specified then these values will be passed to defined JSV instances as parameters with the names binding_strategy, binding_type, binding_amount, binding_step, binding_socket, binding_core, binding_exp_n, binding_exp_socket<id>, binding_exp_core<id>.

    Please note that the length of the socket/core value list of the explicit binding is reported as binding_exp_n. <id> will be replaced by the position of the socket/core pair within the explicit list (0 <= id < binding_exp_n). The first socket/core pair of the explicit binding will be reported with the parameter names binding_exp_socket0 and binding_exp_core0.

    Values that do not apply for the specified binding will not be reported to JSV. E.g. binding_step will only be reported for the striding binding and all binding_exp_* values will passed to JSV if explicit binding was specified. (see -jsv option below or find more information concerning JSV in jsv(1))

-b y[es]|n[o]
    Available for qsub, qrsh only. Qalter does not allow changing this option. This option cannot be embedded in the script file itself.

    Gives the user the possibility to indicate explicitly whether command should be treated as binary or script. If the value of -b is 'y', then command may be a binary or script. The command might not be accessible from the submission host. Nothing except the path of the command will be transferred from the submission host to the execution host. Path aliasing will be applied to the path of command before command will be executed.

    If the value of -b is 'n' then command needs to be a script and it will be handled as script. The script file has to be accessible by the submission host. It will be transferred to the execution host. qsub/qrsh will search directive prefixes within script.

    qsub will implicitly use -b n whereas qrsh will apply the -b y option if nothing else is specified.

    The value specified with this option or the corresponding value specified in qmon will only be passed to defined JSV instances if the value is yes. The name of the parameter will be b. The value will be y also when then long form yes was specified during submission. (see -jsv option below or find more information concerning JSV in

    Please note that submission of command as script (-b n) can have a significant performance impact, especially for short running jobs and big job scripts. Script submission adds a number of operations to the submission process: The job script needs to be
    - parsed at client side (for special comments)
    - transferred from submit client to qmaster
    - spooled in qmaster
    - transferred to execd at job execution
    - spooled in execd
    - removed from spooling both in execd and qmaster once the job is done
    If job scripts are available on the execution nodes, e.g. via NFS, binary submission can be the better choice.

-c occasion_specifier
    Available for qsub and qalter only.

    Defines or redefines whether the job should be checkpointed, and if so, under what circumstances. The specification of the checkpointing occasions with this option overwrites the definitions of the when parameter in the checkpointing environment (see referenced by the qsub -ckpt switch. Possible values for occasion_specifier are

    n	no checkpoint is performed.
    s	checkpoint when batch server is shut down.
    m	checkpoint at minimum CPU interval.
    x	checkpoint when job gets suspended.
    <interval>	checkpoint in the specified time interval.

    The minimum CPU interval is defined in the queue configuration (see for details). <interval> has to be specified in the format hh:mm:ss. The maximum of <interval> and the queue's minimum CPU interval is used if <interval> is specified. This is done to ensure that a machine is not overloaded by checkpoints being generated too frequently.

    The value specified with this option or the corresponding value specified in qmon will be passed to defined JSV instances. The <interval> will be available as parameter with the name c_interval. The character sequence specified will be available as parameter with the name c_occasion. Please note that if you change c_occasion via JSV then the last setting of c_interval will be overwritten and vice versa. (see -jsv option below or find more information concerning JSV in

-ckpt ckpt_name
    Available for qsub and qalter only.

    Selects the checkpointing environment (see to be used for checkpointing the job. Also declares the job to be a checkpointing job.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name ckpt. (see -jsv option below or find more information concerning JSV in

-clear
    Available for qsub, qsh, qrsh, and qlogin only.

    Causes all elements of the job to be reset to the initial default status prior to applying any modifications (if any) appearing in this specific command.

-cwd
    Available for qsub, qsh, qrsh and qalter only.

    Execute the job from the current working directory. This switch will activate xxQS_NAMExx's path aliasing facility, if the corresponding configuration files are present (see

    In the case of qalter, the previous definition of the current working directory will be overwritten if qalter is executed from a different directory than the preceding qsub or qalter.

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name cwd. The value of this parameter will be the absolute path to the current working directory. JSV scripts can remove the path from jobs during the verification process by setting the value of this parameter to an empty string. As a result the job behaves as if -cwd was not specified during job submission. (see -jsv option below or find more information concerning JSV in

-C prefix_string
    Available for qsub and qrsh with script submission (-b n).

    Prefix_string defines the prefix that declares a directive in the job's command. The prefix is not a job attribute, but affects the behavior of qsub and qrsh. If prefix is a null string, the command will not be scanned for embedded directives.
    The directive prefix consists of two ASCII characters which, when appearing in the first two bytes of a script line, indicate that what follows is an xxQS_NAMExx command. The default is "#$".
    The user should be aware that changing the first delimiting character can produce unforeseen side effects. If the script file contains anything other than a "#" character in the first byte position of the line, the shell processor for the job will reject the line and may exit the job prematurely.
    If the -C option is present in the script file, it is ignored.

-dc variable,...
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Removes the given variable(s) from the job's context. Multiple -ac, -dc, and -sc options may be given. The order is important.

    Qalter allows changing this option even while the job executes.

    The outcome of the evaluation of all -ac, -dc, and -sc options or corresponding values in qmon is passed to defined JSV instances as parameter with the name ac. (see -jsv option below or find more information concerning JSV in

-display display_specifier
    Available for qsh and qrsh.

    Directs to use display_specifier in order to contact the X server. The display_specifier has to contain the hostname part of the display name (e.g. myhost:1). Local display names (e.g. :0) cannot be used in grid environments. Values set with the -display option overwrite settings from the submission environment and from -v command line options.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name display. This value will also be available in the job environment which might optionally be passed to JSV scripts. The variable name will be DISPLAY. (see -jsv option below or find more information concerning JSV in

-dl date_time
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Specifies the deadline initiation time in [[CC]YY]MMDDhhmm[.SS] format (see -a option above). The deadline initiation time is the time at which a deadline job has to reach top priority to be able to complete within a given deadline. Before the deadline initiation time the priority of a deadline job will be raised steadily until it reaches the maximum as configured by the xxQS_NAMExx administrator.

    This option is applicable only for users allowed to submit deadline jobs.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name dl. The format for the date_time value is CCYYMMDDhhmm.SS (see -jsv option below or find more information concerning JSV in

-e [[hostname]:]path,...
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Defines or redefines the path used for the standard error stream of the job. For qsh, qrsh and qlogin only the standard error stream of prolog and epilog is redirected. If the path constitutes an absolute path name, the error-path attribute of the job is set to path, including the hostname. If the path name is relative, xxQS_NAMExx expands path either with the current working directory path (if the -cwd switch (see above) is also specified) or with the home directory path. If hostname is present, the standard error stream will be placed in the corresponding location only if the job runs on the specified host. If the path contains a ":" without a hostname, a leading ":" has to be specified.

    By default the file name for interactive jobs is /dev/null. For batch jobs the default file name has the form job_name.ejob_id and job_name.ejob_id.task_id for array job tasks (see -t option below).

    If path is a directory, the standard error stream of the job will be put in this directory under the default file name. If the pathname contains certain pseudo environment variables, their value will be expanded at runtime of the job and will be used to constitute the standard error stream path name. The following pseudo environment variables are supported currently:

    $HOME	home directory on execution machine
    $USER	user ID of job owner
    $JOB_ID	current job ID
    $JOB_NAME	current job name (see -N option)
    $HOSTNAME	name of the execution host
    $TASK_ID	array job task index number

    Alternatively to $HOME the tilde sign "~" can be used as common in or Note, that the "~" sign also works in combination with user names, so that "~<user>" expands to the home directory of <user>. Using another user ID than that of the job owner requires corresponding permissions, of course.

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name e. (see -jsv option below or find more information concerning JSV in

-hard
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Signifies that all -q and -l resource requirements following in the command line will be hard requirements and must be satisfied in full before a job can be scheduled.
    As xxQS_NAMExx scans the command line and script file for xxQS_NAMExx options and parameters it builds a list of resources required by a job. All such resource requests are considered as absolutely essential for the job to commence. If the -soft option (see below) is encountered during the scan then all following resources are designated as "soft requirements" for execution, or "nice-to-have, but not essential". If the -hard flag is encountered at a later stage of the scan, all resource requests following it once again become "essential". The -hard and -soft options in effect act as "toggles" during the scan.

    If this option or a corresponding value in qmon is specified then the corresponding -q and -l resource requirements will be passed to defined JSV instances as parameter with the names q_hard and l_hard. Find for information in the sections describing -q and -l. (see -jsv option below or find more information concerning JSV in

-h | -h {u|s|o|n|U|O|S}...
    Available for qsub (only -h), qrsh, qalter and qresub (hold state is removed when not set explicitly).

    List of holds to place on a job, a task or some tasks of a job.

    `u'	denotes a user hold.
    `s'	denotes a system hold.
    `o'	denotes a operator hold.
    `n'	denotes no hold (requires manager privileges).

    As long as any hold other than `n' is assigned to the job the job is not eligible for execution. Holds can be released via qalter and In case of qalter this is supported by the following additional option specifiers for the -h switch:

    `U'	removes a user hold.
    `S'	removes a system hold.
    `O'	removes a operator hold.

    xxQS_NAMExx managers can assign and remove all hold types, xxQS_NAMExx operators can assign and remove user and operator holds, and users can only assign or remove user holds.

    In the case of qsub only user holds can be placed on a job and thus only the first form of the option with the -h switch alone is allowed. As opposed to this, qalter requires the second form described above.

    An alternate means to assign hold is provided by the facility.

    If the job is a array job (see the -t option below), all tasks specified via -t are affected by the -h operation simultaneously.

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    If this option is specified with qsub or during the submission of a job in qmon then the parameter h with the value u will be passed to the defined JSV instances indicating that the job will be in user hold after the submission finishes. (see -jsv option below or find more information concerning JSV in

-help
    Prints a listing of all options.

-hold_jid wc_job_list
    Available for qsub, qrsh, and qalter only. See for wc_job_list definition.

    Defines or redefines the job dependency list of the submitted job. A reference by job name or pattern is only accepted if the referenced job is owned by the same user as the referring job. The submitted job is not eligible for execution unless all jobs referenced in the comma-separated job id and/or job name list have completed. If any of the referenced jobs exits with exit code 100, the submitted job will remain ineligible for execution.

    With the help of job names or regular pattern one can specify a job dependency on multiple jobs satisfying the regular pattern or on all jobs with the requested name. The name dependencies are resolved at submit time and can only be changed via qalter. New jobs or name changes of other jobs will not be taken into account.

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name hold_jid. (see -jsv option below or find more information concerning JSV in

-hold_jid_ad wc_job_list
    Available for qsub, qrsh, and qalter only. See for wc_job_list definition.

    Defines or redefines the job array dependency list of the submitted job. A reference by job name or pattern is only accepted if the referenced job is owned by the same user as the referring job. Each sub-task of the submitted job is not eligible for execution unless the corresponding sub-tasks of all jobs referenced in the comma-separated job id and/or job name list have completed. If any array task of the referenced jobs exits with exit code 100, the dependent tasks of the submitted job will remain ineligible for execution.

    With the help of job names or regular pattern one can specify a job dependency on multiple jobs satisfying the regular pattern or on all jobs with the requested name. The name dependencies are resolved at submit time and can only be changed via qalter. New jobs or name changes of other jobs will not be taken into account.

    If either the submitted job or any job in wc_job_list are not array jobs with the same range of sub-tasks (see -t option below), the request list will be rejected and the job create or modify operation will error.

    qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name hold_jid_ad. (see -jsv option below or find more information concerning JSV in

-i [[hostname]:]file,...
    Available for qsub, and qalter only.

    Defines or redefines the file used for the standard input stream of the job. If the file constitutes an absolute filename, the input-path attribute of the job is set to path, including the hostname. If the path name is relative, xxQS_NAMExx expands path either with the current working directory path (if the -cwd switch (see above) is also specified) or with the home directory path. If hostname is present, the standard input stream will be placed in the corresponding location only if the job runs on the specified host. If the path contains a ":" without a hostname, a leading ":" has to be specified.

    By default /dev/null is the input stream for the job.

    It is possible to use certain pseudo variables, whose values will be expanded at runtime of the job and will be used to express the standard input stream as described in the -e option for the standard error stream.

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name i. (see -jsv option below or find more information concerning JSV in

-inherit
    Available only for qrsh and

    qrsh allows the user to start a task in an already scheduled parallel job. The option -inherit tells qrsh to read a job id from the environment variable JOB_ID and start the specified command as a task in this job. Please note that in this case, the hostname of the host where the command will be executed must precede the command to execute; the syntax changes to

    qrsh -inherit [ other options ] hostname command [ command_args ]

    Note also, that in combination with -inherit, most other command line options will be ignored. Only the options -verbose, -v and -V will be interpreted. As a replacement to option -cwd please use -v PWD.

    Usually a task should have the same environment (including the current working directory) as the corresponding job, so specifying the option -V should be suitable for most applications.

    Note: If in your system the qmaster tcp port is not configured as a service, but rather via the environment variable xxQS_NAME_Sxx_QMASTER_PORT, make sure that this variable is set in the environment when calling qrsh or qmake with the -inherit option. If you call qrsh or qmake with the -inherit option from within a job script, export xxQS_NAME_Sxx_QMASTER_PORT with the option "-v xxQS_NAME_Sxx_QMASTER_PORT" either as a command argument or an embedded directive.

    This parameter is not available in the JSV context. (see -jsv option below or find more information concerning JSV in

-j y[es]|n[o]
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Specifies whether or not the standard error stream of the job is merged into the standard output stream.
    If both the -j y and the -e options are present, xxQS_NAMExx sets but ignores the error-path attribute.

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    The value specified with this option or the corresponding value specified in qmon will only be passed to defined JSV instances if the value is yes. The name of the parameter will be j. The value will be y also when then long form yes was specified during submission. (see -jsv option below or find more information concerning JSV in

-js job_share
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Defines or redefines the job share of the job relative to other jobs. Job share is an unsigned integer value. The default job share value for jobs is 0.

    The job share influences the Share Tree Policy and the Functional Policy. It has no effect on the Urgency and Override Policies (see and the xxQS_NAMExx Installation and Administration Guide for further information on the resource management policies supported by xxQS_NAMExx).

    In case of the Share Tree Policy, users can distribute the tickets to which they are currently entitled among their jobs using different shares assigned via -js. If all jobs have the same job share value, the tickets are distributed evenly. Otherwise, jobs receive tickets relative to the different job shares. Job shares are treated like an additional level in the share tree in the latter case.

    In connection with the Functional Policy, the job share can be used to weight jobs within the functional job category. Tickets are distributed relative to any uneven job share distribution treated as a virtual share distribution level underneath the functional job category.

    If both the Share Tree and the Functional Policy are active, the job shares will have an effect in both policies, and the tickets independently derived in each of them are added to the total number of tickets for each job.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name js. (see -jsv option below or find more information concerning JSV in

-jsv jsv_url
    Available for qsub, qsh, qrsh and qlogin only.

    Defines a client JSV instance which will be executed to verify the job specification before the job is sent to qmaster.

    In contrast to other options this switch will not be overwritten if it is also used in sge_request files. Instead all specified JSV instances will be executed to verify the job to be submitted.

    The JSV instance which is directly passed with the commandline of a client is executed as first to verify the job specification. After that the JSV instance which might have been defined in various sge_request files will be triggered to check the job. Find more details in man page and

    The syntax of the jsv_url is specified in

-l resource=value,...
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Launch the job in a xxQS_NAMExx queue meeting the given resource request list. In case of qalter the previous definition is replaced by the specified one.

    describes how a list of available resources and their associated valid value specifiers can be obtained.

    There may be multiple -l switches in a single command. You may request multiple -l options to be soft or hard both in the same command line. In case of a serial job multiple -l switches refine the definition for the sought queue.

    Qalter allows changing the value of this option even while the job is running, but only if the initial list of resources does not contain a resource that is marked as consumable. However the modification will only be effective after a restart or migration of the job.

    If this option or a corresponding value in qmon is specified the these hard and soft resource requirements will be passed to defined JSV instances as parameter with the names l_hard and l_soft. If regular expressions will be used for resource requests, then these expressions will be passed as they are. Also shortcut names will not be expanded. (see -jsv option above or find more information concerning JSV in

-m b|e|a|s|n,...
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Defines or redefines under which circumstances mail is to be sent to the job owner or to the users defined with the -M option described below. The option arguments have the following meaning:

    `b'     Mail is sent at the beginning of the job.
    `e'     Mail is sent at the end of the job.
    `a'     Mail is sent when the job is aborted or
            rescheduled.
    `s'     Mail is sent when the job is suspended.
    `n'     No mail is sent.

    Currently no mail is sent when a job is suspended.

    Qalter allows changing the b, e, and a option arguments even while the job executes. The modification of the b option argument will only be in effect after a restart or migration of the job, however.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name m. (see -jsv option above or find more information concerning JSV in

-M user[@host],...
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Defines or redefines the list of users to which the server that executes the job has to send mail, if the server sends mail about the job. Default is the job owner at the originating host.

    Qalter allows changing this option even while the job executes.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name M. (see -jsv option above or find more information concerning JSV in

-masterq wc_queue_list
    Available for qsub, qrsh, qsh, qlogin and qalter. Only meaningful for parallel jobs, i.e. together with the -pe option.

    Defines or redefines a list of cluster queues, queue domains and queue instances which may be used to become the so called master queue of this parallel job. A more detailed description of wc_queue_list can be found in The master queue is defined as the queue where the parallel job is started. The other queues to which the parallel job spawns tasks are called slave queues. A parallel job only has one master queue.

    This parameter has all the properties of a resource request and will be merged with requirements derived from the -l option described above.

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    If this option or a corresponding value in qmon is specified the this hard resource requirement will be passed to defined JSV instances as parameter with the name masterq. (see -jsv option above or find more information concerning JSV in

-notify
    Available for qsub, qrsh (with command) and qalter only.

    This flag, when set causes xxQS_NAMExx to send "warning" signals to a running job prior to sending the signals themselves. If a SIGSTOP is pending, the job will receive a SIGUSR1 several seconds before the SIGSTOP. If a SIGKILL is pending, the job will receive a SIGUSR2 several seconds before the SIGKILL. This option provides the running job, before receiving the SIGSTOP or SIGKILL, a configured time interval to do e.g. cleanup operations. The amount of time delay is controlled by the notify parameter in each queue configuration (see

    Note that the Linux operating system "misused" the user signals SIGUSR1 and SIGUSR2 in some early Posix thread implementations. You might not want to use the -notify option if you are running multi-threaded applications in your jobs under Linux, particularly on 2.0 or earlier kernels.

    Qalter allows changing this option even while the job executes.

    Only if this option is used the parameter named notify with the value y will be passed to defined JSV instances. (see -jsv option above or find more information concerning JSV in

-now y[es]|n[o]
    Available for qsub, qsh, qlogin and qrsh.

    -now y tries to start the job immediately or not at all. The command returns 0 on success, or 1 on failure (also if the job could not be scheduled immediately). For array jobs submitted with the -now option, if all tasks cannot be immediately scheduled, no tasks are scheduled. -now y is default for qsh, qlogin and qrsh

    With the -now n option, the job will be put into the pending queue if it cannot be executed immediately. -now n is default for qsub.

    The value specified with this option or the corresponding value specified in qmon will only be passed to defined JSV instances if the value is yes. The name of the parameter will be now. The value will be y also when then long form yes was specified during submission. (see -jsv option above or find more information concerning JSV in

-N name
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    The name of the job. The name should follow the "name" definition in Invalid job names will be denied at submit time.

    If the -N option is not present, xxQS_NAMExx assigns the name of the job script to the job after any directory pathname has been removed from the script-name. If the script is read from standard input, the job name defaults to STDIN.

    In the case of qsh or qlogin with the -N option is absent, the string `INTERACT' is assigned to the job.

    In the case of qrsh if the -N option is absent, the resulting job name is determined from the qrsh command line by using the argument string up to the first occurrence of a semicolon or whitespace and removing the directory pathname.

    Qalter allows changing this option even while the job executes.

    The value specified with this option or the corresponding value specified in qmon will be passed to defined JSV instances as parameter with the name N. (see -jsv option above or find more information concerning JSV in

-noshell
    Available only for qrsh with a command line.

    Do not start the command line given to qrsh in a user's login shell, i.e. execute it without the wrapping shell.

    This option can be used to speed up execution as some overhead, like the shell startup and sourcing the shell resource files, is avoided.

    This option can only be used if no shell-specific command line parsing is required. If the command line contains shell syntax like environment variable substitution or (back) quoting, a shell must be started. In this case, either do not use the -noshell option or include the shell call in the command line.

    Example:
    qrsh echo '$HOSTNAME'
    Alternative call with the -noshell option
    qrsh -noshell /bin/tcsh -f -c 'echo $HOSTNAME'

-nostdin
    Available only for qrsh.

    Suppress the input stream STDIN - qrsh will pass the option -n to the command. This is especially useful, if multiple tasks are executed in parallel using qrsh, e.g. in a process - it would be undefined, which process would get the input.

-o [[hostname]:]path,...
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    The path used for the standard output stream of the job. The path is handled as described in the -e option for the standard error stream.

    By default the file name for standard output has the form job_name.ojob_id and job_name.ojob_id.task_id for array job tasks (see -t option below).

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name o. (see -jsv option above or find more information concerning JSV in

-ot override_tickets
    Available for qalter only.

    Changes the number of override tickets for the specified job. Requires manager/operator privileges.

-P project_name
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Specifies the project to which this job is assigned. The administrator needs to give permission to individual users to submit jobs to a specific project. (see -aprj option to

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name ot. (see -jsv option above or find more information concerning JSV in

-p priority
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Defines or redefines the priority of the job relative to other jobs. Priority is an integer in the range -1023 to 1024. The default priority value for jobs is 0.

    Users may only decrease the priority of their jobs. xxQS_NAMExx managers and administrators may also increase the priority associated with jobs. If a pending job has higher priority, it is earlier eligible for being dispatched by the xxQS_NAMExx scheduler.

    If this option or a corresponding value in qmon is specified and the priority is not 0 then this value will be passed to defined JSV instances as parameter with the name p. (see -jsv option above or find more information concerning JSV in

-pe parallel_environment n[-[m]]|[-]m,...
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Parallel programming environment (PE) to instantiate. For more detail about PEs, please see the

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    If this option or a corresponding value in qmon is specified then the parameters pe_name, pe_min and pe_max will be passed to configured JSV instances where pe_name will be the name of the parallel environment and the values pe_min and pe_max represent the values n and m which have been provided with the -pe option. A missing specification of m will be expanded as value 9999999 in JSV scripts and it represents the value infinity. (see -jsv option above or find more information concerning JSV in

-pty y[es]|n[o]
    Available for qrsh and qlogin only.

    -pty yes enforces the job to be started in a pseudo terminal (pty). If no pty is available, the job start fails. -pty no enforces the job to be started without a pty. By default, qrsh without a command and qlogin start the job in a pty, qrsh with a command starts the job without a pty.

    This parameter is not available in the JSV context. (see -jsv option above or find more information concerning JSV in

-q wc_queue_list
    Available for qsub, qrsh, qsh, qlogin and qalter.

    Defines or redefines a list of cluster queues, queue domains or queue instances which may be used to execute this job. Please find a description of wc_queue_list in This parameter has all the properties of a resource request and will be merged with requirements derived from the -l option described above.

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    If this option or a corresponding value in qmon is specified the these hard and soft resource requirements will be passed to defined JSV instances as parameters with the names q_hard and q_soft. If regular expressions will be used for resource requests, then these expressions will be passed as they are. Also shortcut names will not be expanded. (see -jsv option above or find more information concerning JSV in

-R y[es]|n[o]
    Available for qsub, qrsh, qsh, qlogin and qalter.

    Indicates whether a reservation for this job should be done. Reservation is never done for immediate jobs, i.e. jobs submitted using the -now yes option. Please note that regardless of the reservation request, job reservation might be disabled using max_reservation in and might be limited only to a certain number of high priority jobs.

    By default jobs are submitted with the -R n option.

    The value specified with this option or the corresponding value specified in qmon will only be passed to defined JSV instances if the value is yes. The name of the parameter will be R. The value will be y also when then long form yes was specified during submission. (see -jsv option above or find more information concerning JSV in

-r y[es]|n[o]
    Available for qsub and qalter only.

    Identifies the ability of a job to be rerun or not. If the value of -r is 'yes', the job will be rerun if the job was aborted without leaving a consistent exit state. (This is typically the case if the node on which the job is running crashes). If -r is 'no', the job will not be rerun under any circumstances.
    Interactive jobs submitted with qsh, qrsh or qlogin are not rerunnable.

    Qalter allows changing this option even while the job executes.

    The value specified with this option or the corresponding value specified in qmon will only be passed to defined JSV instances if the value is yes. The name of the parameter will be r. The value will be y also when then long form yes was specified during submission. (see -jsv option above or find more information concerning JSV in

-sc variable[=value],...
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Sets the given name/value pairs as the job's context. Value may be omitted. xxQS_NAMExx replaces the job's previously defined context with the one given as the argument. Multiple -ac, -dc, and -sc options may be given. The order is important.

    Contexts provide a way to dynamically attach and remove meta-information to and from a job. The context variables are not passed to the job's execution context in its environment.

    Qalter allows changing this option even while the job executes.

    The outcome of the evaluation of all -ac, -dc, and -sc options or corresponding values in qmon is passed to defined JSV instances as parameter with the name ac. (see -jsv option above or find more information concerning JSV in

-shell y[es]|n[o]
    Available only for qsub.

    -shell n causes qsub to execute the command line directly, as if by No command shell will be executed for the job. This option only applies when -b y is also used. Without -b y, -shell n has no effect.

    This option can be used to speed up execution as some overhead, like the shell startup and sourcing the shell resource files is avoided.

    This option can only be used if no shell-specific command line parsing is required. If the command line contains shell syntax, like environment variable substitution or (back) quoting, a shell must be started. In this case either do not use the -shell n option or execute the shell as the command line and pass the path to the executable as a parameter.

    If a job executed with the -shell n option fails due to a user error, such as an invalid path to the executable, the job will enter the error state.

    -shell y cancels the effect of a previous -shell n. Otherwise, it has no effect.

    See -b and -noshell for more information.

    The value specified with this option or the corresponding value specified in qmon will only be passed to defined JSV instances if the value is yes. The name of the parameter will be shell. The value will be y also when then long form yes was specified during submission. (see -jsv option above or find more information concerning JSV in

-soft
    Available for qsub, qsh, qrsh, qlogin and qalter only.

    Signifies that all resource requirements following in the command line will be soft requirements and are to be filled on an "as available" basis.
    As xxQS_NAMExx scans the command line and script file for xxQS_NAMExx options and parameters, it builds a list of resources required by the job. All such resource requests are considered as absolutely essential for the job to commence. If the -soft option is encountered during the scan then all following resources are designated as "soft requirements" for execution, or "nice-to-have, but not essential". If the -hard flag (see above) is encountered at a later stage of the scan, all resource requests following it once again become "essential". The -hard and -soft options in effect act as "toggles" during the scan.

    If this option or a corresponding value in qmon is specified then the corresponding -q and -l resource requirements will be passed to defined JSV instances as parameter with the names q_soft and l_soft. Find for information in the sections describing -q and -l. (see -jsv option above or find more information concerning JSV in

-sync y[es]|n[o]
    Available for qsub.

    -sync y causes qsub to wait for the job to complete before exiting. If the job completes successfully, qsub's exit code will be that of the completed job. If the job fails to complete successfully, qsub will print out a error message indicating why the job failed and will have an exit code of 1. If qsub is interrupted, e.g. with CTRL-C, before the job completes, the job will be canceled.
    With the -sync n option, qsub will exit with an exit code of 0 as soon as the job is submitted successfully. -sync n is default for qsub.
    If -sync y is used in conjunction with -now y, qsub will behave as though only -now y were given until the job has been successfully scheduled, after which time qsub will behave as though only -sync y were given.
    If -sync y is used in conjunction with -t n[-m[:i]], qsub will wait for all the job's tasks to complete before exiting. If all the job's tasks complete successfully, qsub's exit code will be that of the first completed job tasks with a non-zero exit code, or 0 if all job tasks exited with an exit code of 0. If any of the job's tasks fail to complete successfully, qsub will print out an error message indicating why the job task(s) failed and will have an exit code of 1. If qsub is interrupted, e.g. with CTRL-C, before the job completes, all of the job's tasks will be canceled.

    Information that this switch was specified during submission is not available in the JSV context. (see -jsv option above or find more information concerning JSV in

-S [[hostname]:]pathname,...
    Available for qsub, qsh and qalter.

    Specifies the interpreting shell for the job. Only one pathname component without a host specifier is valid and only one path name for a given host is allowed. Shell paths with host assignments define the interpreting shell for the job if the host is the execution host. The shell path without host specification is used if the execution host matches none of the hosts in the list.

    Furthermore, the pathname can be constructed with pseudo environment variables as described for the -e option above.

    In the case of qsh the specified shell path is used to execute the corresponding command interpreter in the (via its -e option) started on behalf of the interactive job. Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameter with the name S. (see -jsv option above or find more information concerning JSV in

-t n[-m[:s]]
    Available for qsub and qalter only.

    Submits a so called Array Job, i.e. an array of identical tasks being differentiated only by an index number and being treated by xxQS_NAMExx almost like a series of jobs. The option argument to -t specifies the number of array job tasks and the index number which will be associated with the tasks. The index numbers will be exported to the job tasks via the environment variable xxQS_NAME_Sxx_TASK_ID. The option arguments n, m and s will be available through the environment variables xxQS_NAME_Sxx_TASK_FIRST, xxQS_NAME_Sxx_TASK_LAST and xxQS_NAME_Sxx_TASK_STEPSIZE.

    Following restrictions apply to the values n and m:

        1 <= n <= MIN(2^31-1, max_aj_tasks)
        1 <= m <= MIN(2^31-1, max_aj_tasks)
        n <= m

    max_aj_tasks is defined in the cluster configuration (see

    The task id range specified in the option argument may be a single number, a simple range of the form n-m or a range with a step size. Hence, the task id range specified by 2-10:2 would result in the task id indexes 2, 4, 6, 8, and 10, for a total of 5 identical tasks, each with the environment variable xxQS_NAME_Sxx_TASK_ID containing one of the 5 index numbers.

    All array job tasks inherit the same resource requests and attribute definitions as specified in the qsub or qalter command line, except for the -t option. The tasks are scheduled independently and, provided enough resources exist, concurrently, very much like separate jobs. However, an array job or a sub-array there of can be accessed as a single unit by commands like or See the corresponding manual pages for further detail.

    Array jobs are commonly used to execute the same type of operation on varying input data sets correlated with the task index number. The number of tasks in a array job is unlimited.

    STDOUT and STDERR of array job tasks will be written into different files with the default location

    <jobname>.['e'|'o']<job_id>'.'<task_id>

    In order to change this default, the -e and -o options (see above) can be used together with the pseudo environment variables $HOME, $USER, $JOB_ID, $JOB_NAME, $HOSTNAME, and $xxQS_NAME_Sxx_TASK_ID.

    Note, that you can use the output redirection to divert the output of all tasks into the same file, but the result of this is undefined.

    If this option or a corresponding value in qmon is specified then this value will be passed to defined JSV instances as parameters with the name t_min, t_max and t_step (see -jsv option above or find more information concerning JSV in

    -tc max_running_tasks

-allow users to limit concurrent array job task execution. Parameter
max_running_tasks specifies maximum number of simultaneously running tasks. For example we have running SGE with 10 free slots. We call qsub -t 1-100 -tc 2 jobscript. Then only 2 tasks will be scheduled to run even when 8 slots are free.

-terse
    Available for qsub only.

    -terse causes the qsub to display only the job-id of the job being submitted rather than the regular "Your job ..." string. In case of an error the error is reported on stderr as usual.
    This can be helpful for scripts which need to parse qsub output to get the job-id.

    Information that this switch was specified during submission is not available in the JSV context. (see -jsv option above or find more information concerning JSV in

-u username,...
    Available for qalter only. Changes are only made on those jobs which were submitted by users specified in the list of usernames. For managers it is possible to use the qalter -u '*' command to modify all jobs of all users.

    If you use the -u switch it is not permitted to specify an additional wc_job_range_list.

-v variable[=value],...
    Available for qsub, qrsh (with command argument) and qalter.

    Defines or redefines the environment variables to be exported to the execution context of the job. If the -v option is present xxQS_NAMExx will add the environment variables defined as arguments to the switch and, optionally, values of specified variables, to the execution context of the job.

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    All environment variables specified with -v, -V or the DISPLAY variable provided with -display will be exported to the defined JSV instances only optionally when this is requested explicitly during the job submission verification. (see -jsv option above or find more information concerning JSV in

-verbose
    Available only for qrsh and

    Unlike qsh and qlogin, qrsh does not output any informational messages while establishing the session, compliant with the standard and system calls. If the option -verbose is set, qrsh behaves like the qsh and qlogin commands, printing information about the process of establishing the or session.

-verify
    Available for qsub, qsh, qrsh, qlogin and qalter.

    Instead of submitting a job, prints detailed information about the would-be job as though -j were used, including the effects of command-line parameters and the external environment.

-V  Available for qsub, qsh, qrsh with command and qalter.

    Specifies that all environment variables active within the qsub utility be exported to the context of the job.

    All environment variables specified with -v, -V or the DISPLAY variable provided with -display will be exported to the defined JSV instances only optionally when this is requested explicitly during the job submission verification. (see -jsv option above or find more information concerning JSV in

-w e|w|n|p|v
    Available for qsub, qsh, qrsh, qlogin and qalter.

    Specifies a validation level applied to the job to be submitted (qsub, qlogin, and qsh) or the specified queued job (qalter). The information displayed indicates whether the job can possibly be scheduled assuming an empty system with no other jobs. Resource requests exceeding the configured maximal thresholds or requesting unavailable resource attributes are possible causes for jobs to fail this validation.

    The specifiers e, w, n and v define the following validation modes:

    `e'	error - jobs with invalid requests will be
    	rejected.
    `w'	warning - only a warning will be displayed
    	for invalid requests.
    `n'	none - switches off validation; the default for
    	qsub, qalter, qrsh, qsh
    	and qlogin.
    `p'	poke - does not submit the job but prints a
         validation report based on a cluster as is with
         all resource utilizations in place.
    `v'	verify - does not submit the job but prints a
         validation report based on an empty cluster.

    Note, that the necessary checks are performance consuming and hence the checking is switched off by default. It should also be noted that load values are not taken into account with the verification since they are assumed to be too volatile. To cause -w e verification to be passed at submission time, it is possible to specify non-volatile values (non-consumables) or maximum values (consumables) in complex_values.

-wd working_dir
    Available for qsub, qsh, qrsh and qalter only.

    Execute the job from the directory specified in working_dir. This switch will activate xxQS_NAMExx's path aliasing facility, if the corresponding configuration files are present (see

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however. The parameter value will be available in defined JSV instances as parameter with the name cwd (see -cwd switch above or find more information concerning JSV in

command
    Available for qsub and qrsh only.

    The job's scriptfile or binary. If not present or if the operand is the single-character string '-', qsub reads the script from standard input.

    The command will be available in defined JSV instances as parameter with the name CMDNAME (see -jsv option above or find more information concerning JSV in

command_args
    Available for qsub, qrsh and qalter only.

    Arguments to the job. Not valid if the script is entered from standard input.

    Qalter allows changing this option even while the job executes. The modified parameter will only be in effect after a restart or migration of the job, however.

    The number of command arguments is provided to configured JSV instances as parameter with the name CMDARGS. Also the argument values can by accessed. Argument names have the format CMDARG<number> where <number> is a integer between 0 and CMDARGS - 1. (see -jsv option above or find more information concerning JSV in

xterm_args
    Available for qsh only.

    Arguments to the executable, as defined in the configuration. For details, refer to

    Information concerning xterm_args will be available in JSV context as parameters with the name CMDARGS and CMDARG<number>. Find more information above in section command_args. (see -jsv option above or find more information concerning JSV in

ENVIRONMENTAL VARIABLES

xxQS_NAME_Sxx_ROOT
    Specifies the location of the xxQS_NAMExx standard configuration files.

xxQS_NAME_Sxx_CELL
    If set, specifies the default xxQS_NAMExx cell. To address a xxQS_NAMExx cell qsub, qsh, qlogin or qalter use (in the order of precedence):

        The name of the cell specified in the environment variable xxQS_NAME_Sxx_CELL, if it is set.

        The name of the default cell, i.e. default.

xxQS_NAME_Sxx_QMASTER_PORT
    If set, specifies the tcp port on which is expected to listen for communication requests. Most installations will use a services map entry for the service "sge_qmaster" instead to define that port.

DISPLAY
    For qsh jobs the DISPLAY has to be specified at job submission. If the DISPLAY is not set by using the -display or the -v switch, the contents of the DISPLAY environment variable are used as default.

In addition to those environment variables specified to be exported to the job via the -v or the -V option (see above) qsub, qsh, and qlogin add the following variables with the indicated values to the variable list:

xxQS_NAME_Sxx_O_HOME

TMPDIR
    The absolute path to the job's temporary working directory.

TMP The same as TMPDIR; provided for compatibility with NQS.

TZ  The time zone variable imported from if set.

USER
    The user's login name from the file.

SGE_JSV_TIMEOUT
    If the response time of the client JSV is greater than this timeout value, then the JSV will attempt to be re-started. The default value is 10 seconds, and this value must be greater than 0. If the timeout has been reached, the JSV will only try to re-start once, if the timeout is reached again an error will occur.

RESTRICTIONS

There is no controlling terminal for batch jobs under xxQS_NAMExx, and any tests or actions on a controlling terminal will fail. If these operations are in your .login or .cshrc file, they may cause your job to abort.

Insert the following test before any commands that are not pertinent to batch jobs in your .login:

    if ( $?JOB_NAME) then
        echo "xxQS_NAMExx spooled job"
        exit 0
    endif

Don't forget to set your shell's search path in your shell start-up before this code.

EXIT STATUS
The following exit values are returned:

0   Operation was executed successfully.

25  It was not possible to register a new job according to the configured max_u_jobs or max_jobs limit. Additional information may be found in

>0  Error occurred.
