Platform LSF Reference Version 6.2

Parameters
Platform LSF Reference
564
LSF_POE_TIMEOUT_SELECT
Syntax
LSF_POE_TIMEOUT_SELECT=
seconds
Description
Specifies the time in seconds for the poe_w wrapper to wait for connections from the
pmd_w wrapper. pmd_w is the wrapper for pmd (IBM PE Partition Manager Daemon).
LSF_POE_TIMEOUT_SELECT can also be set as an environment variable for
poe_w
to read.
Default
160 seconds
LSF_PIM_INFODIR
Syntax
LSF_PIM_INFODIR=
path
Description
The path to where PIM writes the pim.info.host_name file.
Specifies the path to where the process information is stored. The process information
resides in the file
pim.info.host_name. The PIM also reads this file when it starts
so that it can accumulate the resource usage of dead processes for existing process
groups.
Default
Undefined. If undefined, the system uses /tmp.
LSF_PIM_SLEEPTIME
Syntax
LSF_PIM_SLEEPTIME=
time_seconds
Description
The reporting period for PIM.
PIM updates the process information every 15 minutes unless an application queries this
information. If an application requests the information, PIM will update the process
information every LSF_PIM_SLEEPTIME seconds. If the information is not queried
by any application for more than 5 minutes, the PIM will revert back to the 15 minute
update period.
Default
15
LSF_PIM_SLEEPTIME_UPDATE
Syntax LSF_PIM_SLEEPTIME_UPDATE=y | n
Description
UNIX only.
Use this parameter to improve job throughput and reduce a job’s start time if there are
many jobs running simultaneously on a host. This parameter reduces communication
traffic between
sbatchd and PIM on the same host.
When this parameter is undefined or set to n,
sbatchd queries PIM as needed for job
process information.
When this parameter is defined,
sbatchd does not query PIM immediately as it needs
information—
sbatchd will only query PIM every LSF_PIM_SLEEPTIME seconds.
Limitations
When this parameter is defined:
◆ sbatchd may be intermittently unable to retrieve process information for jobs
whose run time is smaller than LSF_PIM_SLEEPTIME.
