LSF Version 7.3 - Using Platform LSF HPC

MANDATORY_EXTSCHED options override any conflicting job-level options set by
-extsched options on the bsub command.
For example, if the queue specifies:
MANDATORY_EXTSCHED=PSET[CELLS=2]
and a job is submitted with no topology requirements requesting 6 CPUs (bsub n 6),
a pset is allocated using 2 cells with 3 CPUs in each cell.
If the job is submitted:
bsub -n 6 -ext "PSET[CELLS=3]" myjob
MANDATORY_EXTSCHED overrides the pset option in the command, so a pset is
allocated using 2 cells with 3 CPUs in each cell.
Use the CELL_LIST option in MANDATORY_EXTSCHED to restrict the cells
available for allocation to pset jobs. For example, if the queue specifies:
MANDATORY_EXTSCHED=PSET[CELL_LIST=1-7]
job psets can only use cells 1 to 7; cell 0 is not used for pset jobs.
