LSF Version 7.3 - Platform LSF Configuration Reference

Description
For Cray NQS compatibility only.
If the NQS version on a Cray is NQS 80.42 or NQS 71.3, this parameter does not need to be
defined.
If the version is NQS 1.1 on a Cray, set this parameter to 251918848. This is the is the qstat
flag that LSF uses to retrieve requests on Cray in long format.
For other versions of NQS on a Cray, run the NQS qstat command. The value of Npk_int
[1] in the output is the value you need for this parameter. Refer to the NQS chapter in
Administering Platform LSF for more details.

PARALLEL_SCHED_BY_SLOT
Syntax
PARALLEL_SCHED_BY_SLOT=y | Y
Description
If defined, LSF schedules jobs based on the number of slots assigned to the hosts instead of
the number of CPUs. These slots can be defined by host in lsb.hosts or by slot limit in
lsb.resources.
All slot-related messages still show the word “processors”, but actually refer to “slots” instead.
Similarly, all scheduling activities also use slots instead of processors.
