Since many features of LSF are not supported by NQS, the following queue
configuration parameters are ignored for NQS forward queues: PJOB_LIMIT,
POLICIES, RUN_WINDOW, DISPATCH_WINDOW, RUNLIMIT, HOSTS, MIG.
In addition, scheduling load threshold parameters are ignored because NQS does not
provide load information about hosts.
Default
Undefined
PJOB_LIMIT
Syntax
PJOB_LIMIT=
float
Description
Per-processor job slot limit for the queue.
Maximum number of job slots that this queue can use on any processor. This limit is
configured per processor, so that multiprocessor hosts automatically run more jobs.
Default
Unlimited
POST_EXEC
Syntax
POST_EXEC=
command
Description
A command run on the execution host after the job.
UNIX
The entire contents of the configuration line of the pre- and post-execution commands
are run under
/bin/sh -c, so shell features can be used in the command.
The pre- and post-execution commands are run in
/tmp.
Standard input and standard output and error are set to:
/dev/null
The output from the pre- and post-execution commands can be explicitly redirected to
a file for debugging purposes.
The PATH environment variable is set to:
'/bin /usr/bin /sbin/usr/sbin'
Windows
The pre- and post-execution commands are run under cmd.exe/c.
To run these commands under a different user account (such as root, to do privileged
operations, if necessary), configure the parameter LSB_PRE_POST_EXEC_USER in
lsf.sudoers.
Standard input and standard output and error are set to NUL. The output from the pre-
and post-execution commands can be explicitly redirected to a file for debugging
purposes.
The PATH is determined by the setup of the LSF Service.
◆ Other environment variables set for the job are also set for the pre- and post-
execution commands.
◆ When a job is dispatched from a queue that has a pre-execution command, the
system will remember the post-execution command defined for the queue from
which the job is dispatched. If the job is later switched to another queue or the post-
execution command of the queue is changed, the original post-execution command
will be run.
