LSF Version 7.3 - Using Platform LSF HPC

If topology options (nodes, ptile, or base) or flags (rails or railmask) are set
in DEFAULT_EXTSCHED, and you do not want to specify values for these options,
use the keyword with no value in the
-extsched option of bsub. For example, if
DEFAULT_EXTSCHED=RMS[nodes=2], and you do not want to specify any node
option at all, use
-extsched "RMS[RMS_SNODE;nodes=]".
Running jobs on any host type
You can specify several types of topology scheduling options at job submission and LSF
will schedule jobs appropriately. Jobs that do not specify RMS-related options can be
dispatched to RMS hosts, and jobs with RMS-related options can be dispatched to non-
RMS hosts.
Use the LSF resource requirements specification (
-R option of bsub or RES_REQ in
queue definition in
lsb.queues) to identify the host types required for your job.
For example, HP pset hosts and Linux/QsNet hosts running RMS can exist in the same
LSF cluster. Use the
-R option to define resource requirements for either HP pset hosts
or Linux/QsNet hosts. Your job will run on either host type, but not both.
For example:
bsub n -8 -R "pset || rms" -ext "RMS[ptile=2];PSET[PTILE=2]" myjob
Runs myjob on an HP pset host or an RMS host if one is available, but not both. If it
runs on an RMS host, the
RMS[ptile=2] option is applied. If it runs on a pset host,
the RMS option is ignored and the
PSET[PTILE=2] option is applied.
Viewing nodes allocated to your job
Use bjobs -l to see RMS allocation information for a running job. For example, the
following job allocates nodes on hosts
hostA and hostB, with resource ID 3759 in the
partition named
parallel:
bjobs -l 723
