msub allows users to submit jobs directly to Moab. When a job is submitted directly to a resource manager (such as TORQUE), it is constrained to run on only those nodes that the resource manager is directly monitoring. In many instances, a site may be controlling multiple resource managers. When a job is submitted to Moab rather than to a specific resource manager, it is not constrained as to what nodes it is executed on. msub can accept command line arguments (with the same syntax as qsub), job scripts (in either PBS or LoadLeveler syntax), or the SSS Job XML specification.
Submitted jobs can then be viewed and controlled via the mjobctl command.
|Flags specified in the following table are not necessarily supported by all resource managers.|
AccessWhen Moab is configured to run as root, any user may submit jobs via msub.
|Description:||Declares the time after which the job is eligible for execution.|
Moab will not schedule the job until 1:00 pm on December 4, of the current year.
> msub -a 12041300 cmd.pbs
|Description:||Defines the account associated with the job.|
Moab will associate this job with account research.
> msub -A research cmd.pbs
|Description:||Checkpoint of the will occur at the specified
n - No Checkpoint is to be performed.
s - Checkpointing is to be performed only when the server executing the job is shut down.
c - Checkpoint is to be performed at the default minimum time for the server executing the job.
c=<minutes> - Checkpoint is to be performed at an interval of minutes.
The job will be checkpointed every 12 minutes.
> msub -c c=12 cmd.pbs
|Default:||First known prefix (#PBS, #@, #BSUB, #!, #MOAB, #MSUB)|
|Description:||Specifies which directive prefix should be used from a job script.
Moab will use the #MYPREFIX directive specified in cmd.pbs, setting the wallclock limit to five hours.
> msub -C '#MYPREFIX' cmd.pbs #MYPREFIX -l walltime=5:00:00 (in cmd.pbs)
|Default:||Depends on the RM being used. If using TORQUE, the default is $HOME. If using SLURM, the default is the submission directory.|
|Description:||Specifies which directory the job should execute in.|
The job will begin execution in the /home/test/job12 directory.

The STDERR stream of the job will be placed in the relative (to execution) directory specified.
> msub -e test12/stderr.txt
|Description:||Moab adds the following variables, if populated, to the job's environment:
In SLURM environments, not all variables will be populated since the variables are added at submission (such as NODELIST). With TORQUE/PBS, the variables are added just before the job is started.
This feature only works with SLURM and TORQUE/PBS.
The job mySim will be submitted with extra environment variables.
> msub -E mySim.cmd
|Description:||Specifies the flags TORQUE will pass to the job script at execution time.
TORQUE will pass parameters arg1 and arg2 to the job.sh script when the job executes.

|Default:||n (not merged)|
|Description:||Declares if the standard error stream of the job will be merged with the standard output stream of the job. If "oe" is specified, the error and output streams will be merged into the output stream.|
STDOUT and STDERR will be merged into one file.
> msub -j oe cmd.sh
|Default:||n (not retained)|
|Description:||Defines which (if either) of output and error streams will be retained on the execution host (overrides path for stream).|
STDOUT and STDERR for the job will be retained on the execution host.
> msub -k oe myjob.sh
|Description:||Tells the client to continue running until the submitted job is completed. The
client will query the status of the job every 5 seconds. The time interval
between queries can be specified or disabled via MSUBQUERYINTERVAL.
*Only shows up after job completion.

-l [BANDWIDTH|DDISK|DEADLINE|DEPEND|DMEM|EXCLUDENODES|FEATURE...|]Additional options can be referenced on the resource manager extensions page.
Defines the resources that are required by the job and establishes a limit to the amount of resource that can be consumed. Resources native to the resource manager, scheduler resource manager extensions, or job flags may be specified. Note that resource lists are dependent on the resource manager in use.
> msub -l nodes=32:ppn=2,pmem=1800mb,walltime=3600,VAR=testvar:myvalue cmd.sh
The job requires 32 nodes with 2 processors each, 1800 MB per task, a walltime of 3600 seconds, and a variable named testvar with a value of myvalue.
> msub nodes=32:ppn=2 -l advres=!<resvid>
This entry would tell Moab to only consider resources outside of the specified <reservation id>.
|Format:||<STRING> (either n or one or more of the characters a, b, and e)|
|Description:||Defines the set of conditions (abort,begin,end) when the server will send a mail message about the job to the user.|
Mail notifications will be sent when the job begins and ends.
> msub -m be cmd.sh
|Description:||Specifies the list of users to whom mail is sent by the execution server. Overrides the EMAILADDRESS specified on the USERCFG credential.|
Mail will be sent to the specified users if the job is aborted.
> msub -M jon@node01,bill@node01,jill@node02 cmd.sh
|Default:||STDIN or name of job script|
|Description:||Specifies the user-specified job name attribute.|
Job will be associated with the name chemjob3.
> msub -N chemjob3 cmd.sh
|Format:||[<hostname>:]<path> - %J and %I are acceptable variables. %J is the master array name and %I is the array member index in the array.|
|Description:||Defines the path to be used for the standard output stream of the batch job.|
> msub -o test12/stdout.txt

A job array is submitted and the name of the output files includes the master array index and the array member index.
> msub -t 1-2 -o /home/jsmith/simulations/%J-%I.out ~/sim5.sh
|Format:||<INTEGER> (between -1024 and 0)|

|Description:||Allows the for the specification of additional job attributes (See Resource Manager Extension).|
> msub -W x=GRES:matlab:1 cmd.sh
The job requires one resource of "matlab".
This flag can be used to set a filter for what namespaces will be passed from a job to a trigger using a comma-delimited list. This limits the trigger's action to objects contained in certain workflows. For more information, see Filtering VC Triggers by Namespace.
> msub -W x="trigns=vc1,vc2"
The job passes namespaces vc1 and vc2 to triggers.
|Format:||<script> or <command>|
|Description:|| When running an interactive job, the -x flag makes it so that the corresponding script won't be parsed for PBS directives, but is instead a command that is launched once the interactive job has started. The job terminates at the completion of this command. This option works only when using TORQUE.
> msub -I -x ./script.pl > msub -I -x /tmp/command
|Description:||The job's identifier will not be printed to stdout upon submission.|
No job identifier will be printout the stdout upon successful submission.
> msub -z cmd.sh
The msub command supports job scripts written in any one of the following languages:
|PBS/TORQUE Job Submission Language||---|
|LoadLeveler Job Submission Language||Use the INSTANTSTAGE parameter as only a subset of the command file keywords are interpreted by Moab.|
|SSS XML Job Object Specification||---|
|LSF Job Submission Language||enabled in Moab 4.2.4 and higher|
Sites that wish to automatically add parameters to every job submission can populate the file '/etc/msubrc' with global parameters that every job submission will inherit.For example, if a site wished every job to request a particular generic resource they could use the following /etc/msubrc:
msub is designed to be as flexible as possible, allowing users accustomed to PBS, LSF, or LoadLeveler syntax, to continue submitting jobs as they normally would. It is not recommended that different styles be mixed together in the same msub command.
When only one resource manager is configured inside of Moab, all jobs are immediately staged to the only resource manager available. However, when multiple resource managers are configured Moab will determine which resource manager can run the job soonest. Once this has been determined, Moab will stage the job to the resource manager.
It is possible to have Moab take a "best effort" approach at submission time using the forward flag. When this flag is specified, Moab will do a quick check and make an intelligent guess as to which resource manager can run the job soonest and then immediately stage the job.
Moab can be configured to instantly stage a job to the underlying resource manager (like TORQUE/LOADLEVELER) through the parameter INSTANTSTAGE. When set inside moab.cfg, Moab will migrate the job instantly to an appropriate resource manager. Once migrated, Moab will destroy all knowledge of the job and refresh itself based on the information given to it from the underlying resource manager.
In most instances Moab can determine what syntax style the job belongs to (PBS or LoadLeveler); if Moab is unable to make a guess, it will default the style to whatever resource manager was configured at compile time. If LoadLeveler and PBS were both compiled then LoadLeveler takes precedence.
Moab can translate a subset of job attributes from one syntax to another. It is therefore possible to submit a PBS style job to a LoadLeveler resource manager, and vice versa, though not all job attributes will be translated.
