The not operator can only be used with the all keyword or to exclude users from
user groups.
The not operator does not exclude LSF administrators from the queue definintion.
lsf.conf
◆ LSB_MAX_PROBE_SBD=integer
Specifies the maximum number of
sbatchd instances can be polled by mbatchd
in the interval MBD_SLEEP_TIME/10. Use this parameter in large clusters to
reduce the time it takes for
mbatchd to probe all sbatchds.
◆ LSB_DISABLE_RERUN_POST_EXEC=y | Y
If set, and the job is rerunnable, the POST_EXEC configured in the queue is not
executed if the job is rerun.
Running of post-execution commands upon restart of a rerunanble job may not
always be desirable. For example, if the post-exec removes certain files, or does
other cleanup that should only happen if the job finishes successfully, use
LSB_DISABLE_RERUN_POST_EXEC to prevent the post-exec from running
and allow the succesful continuation of the job when it reruns.
◆ LSF_ENABLE_DUALCORE=Y | N
Enables job scheduling based on dual-core CPU information for a host. If yes (Y),
LSF scheduling policies use the detected number of CPU cores as the number of
physical CPUs on the host instead of the number of physical CPUs for job
scheduling. For a dual-core host,
lshosts shows the number of cores under
ncpus instead of physical CPUs.
To make use of dual-core CPUs for scheduling, hosts must have the
lsf_dualcore_x86 license feature enabled. Each dual core processor requires
one standard LSF license and one lsf_dualcore_x86 license. Use lshosts -l to
see the number of dual-core licenses enabled and needed.
◆ LSF_LICENSE_ACCT_PATH=dir
Specifies the location for the license accounting files. These include the license
accounting files for LSF Family products.
Use this parameter to define the location of all the license accounting files. By
defining this parameter, you can store the license accounting files for the LSF Family
of products in the same directory for convenience.
◆ LSF_LICENSE_NOTIFICATION_INTERVAL=hours
Specifies how often notification email is sent to the primary cluster administrator
about overuse of LSF Family product licenses and License Scheduler tokens.
The default is 24 hours.
◆ LSF_SHIFT_JIS_INPUT=y | n
Enables LSF to accept Shift-JIS character encoding for job information (for
example, user names, queue names, job names, job group names, project names,
commands and arguments, esub parameters, external messages, etc.)
◆ MC_PLUGIN_REMOTE_RESOURCE=y
MultiCluster job forwarding model only. By default, the submission cluster does not
consider remote resources. Define MC_PLUGIN_REMOTE_RESOURCE=y in
the submission cluster to allow consideration of remote resources.
