MAX_SBD_CONNS in “lsb.params”
LSB_MAX_PROBE_SBD
Syntax LSB_MAX_PROBE_SBD=integer
Description
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.
The value of LSB_MAX_PROBE_SBD cannot be greater than the number of hosts in
the cluster. If it is, mbatchd adjusts the value of LSB_MAX_PROBE_SBD to be same
as the number of hosts.
After modfying LSB_MAX_PROBE_SBD, use
badmin mbdrestart to restart
mbatchd and let the modified value take effect.
If LSB_MAX_PROBE_SBD is defined, the value of MAX_SBD_FAILED in
lsb.params can be less than 3.
Valid Values
Any positive integer between 0 and 64
Default
20

MAX_SBD_FAIL in “lsb.params”
LSB_MAX_NQS_QUEUES
Syntax
LSB_MAX_NQS_QUEUES=nqs_queues
Description
The maximum number of NQS queues allowed in the LSF cluster. Required for LSF to
work with NQS. You must restart
mbatchd if you change the value of
LSB_MAX_NQS_QUEUES.
The total number of NQS queues configured by NQS_QUEUES in
lsb.queues
cannot exceed the value of LSB_MAX_NQS_QUEUES. NQS queues in excess of the
maximum queues are ignored.
If you do not define LSB_MAX_NQS_QUEUES or define an incorrect value, LSF-
NQS interoperation is disabled.
Valid Values
Any positive integer
Default
None
LSB_MBD_PORT
See “LSF_LIM_PORT, LSF_RES_PORT, LSB_MBD_PORT, LSB_SBD_PORT” on
page 555.
LSB_MC_CHKPNT_RERUN
Syntax LSB_MC_CHKPNT_RERUN=y | n
Description
For checkpointable MultiCluster jobs, if a restart attempt fails, the job will be rerun from
the beginning (instead of from the last checkpoint) without administrator or user
intervention.
