LSF Version 7.3 - Using Platform LSF HPC

If topology options (nodes, ptile, or base) or rail 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=]".
See “bsub command” on page 117 for more information.
Syntax in the form DEFAULT_EXTSCHED=extsched_options is obsolete (for
example, DEFAULT_EXTSCHED=RMS_SNODE). You should use the syntax of
the form DEFAULT_EXTSCHED=RMS[extsched_options] (for example,
DEFAULT_EXTSCHED=RMS[RMS_SNODE]).
The queue named rms defined during installation specifies
DEFAULT_EXTSCHED=RMS[RMS_SNODE]. LSF uses the RMS_SNODE
scheduling policy if no allocation type is specified at job submission.
MANDATORY_EXTSCHED=RMS[ allocation_type ;topology ;flags ]
Specifies mandatory topology scheduling options for the queue.
-extsched options on the bsub command are merged with
MANDATORY_EXTSCHED options, and MANDATORY_EXTSCHED options
override any conflicting job-level options set by
-extsched.
Overrides
-extsched options on the bsub command.
For example, if
MANDATORY_EXTSCHED=RMS[RMS_SNODE;rails=2] and a job is
submitted with
-extsched "RMS[base=hostA;rails=1;ptile=2]", LSF uses
the following resulting options for scheduling:
RMS_SNODE;rails=2;base=hostA;ptile=2
MANDATORY_EXTSCHED can be used in combination with
DEFAULT_EXTSCHED in the same queue. For example:
◆ -extsched "RMS[base=hostA;ptile=2]"
◆ DEFAULT_EXTSCHED=RMS[rails=2]
◆ MANDATORY_EXTSCHED=RMS[RMS_SNODE;ptile=4]
LSF uses the following resulting options for scheduling:
RMS_SNODE;rails=2;base=hostA;ptile=4
See “bsub command” on page 117 for more information.
If you want to prevent users from setting the topology options (
nodes, ptile, or
base) or flags (rails or railmask) in the -extsched option of bsub, use the
keyword with no value. For example, if the job is submitted with
-extsched "RMS[RMS_SNODE;nodes=4]", use
MANDATORY_EXTSCHED=RMS[nodes=] to override both of these settings.
Syntax in the form MANDATORY_EXTSCHED=extsched_options is obsolete
(for example, MANDATORY_EXTSCHED=RMS_SNODE). You should use the
syntax of the form MANDATORY_EXTSCHED=RMS[extsched_options] (for
example, MANDATORY_EXTSCHED=RMS[RMS_SNODE]).
