LSF Version 7.3 - Using Platform LSF HPC

Optional configuration
After installation, you can define the following in lsf.conf:
◆ LSF_LOGDIR=directory
In large clusters, you should set LSF_LOGDIR to a local file system (for example,
/var/log/lsf).
◆ LSB_RLA_WORKDIR=directory parameter, where directory is the location of the
status files for RLA. Allows RLA to recover its original state when it restarts. When
RLA first starts, it creates the directory defined by LSB_RLA_WORKDIR if it does
not exist, then creates subdirectories for each host.
You should avoid using
/tmp or any other directory that is automatically cleaned up
by the system. Unless your installation has restrictions on the LSB_SHAREDIR
directory, you should use the default:
LSB_SHAREDIR/ cluster_name /rla_workdir
On IRIX or TRIX, you should not use a CXFS file system for
LSB_RLA_WORKDIR.
◆ On Linux hosts running HP MPI, set the full path to the HP vendor MPI library
libmpirm.so.
For example, if HP MPI is installed in
/opt/hpmpi:
LSF_VPLUGIN="/opt/hpmpi/lib/linux_ia32/libmpirm.so"
◆ LSB_RLA_UPDATE=time_seconds
Specifies how often the LSF scheduler refreshes information from RLA.
Default: 600 seconds
◆ LSB_RLA_HOST_LIST="host_name ..."
On Linux/QsNet hosts, the LSF scheduler can contact the RLA running on any
host for RMS allocation requests. LSB_RLA_HOST_LIST defines a list of hosts to
restrict which RLAs the LSF scheduler contacts.
If LSB_RLA_HOST_LIST is configured, you must list at least one host per RMS
partition for the RMS partition to be considered for job scheduling.
Listed hosts must be defined in
lsf.cluster. cluster_name .
◆ LSB_RLA_UPDATE=seconds
On Linux/QsNet hosts, specifies how often RLA should refresh its RMS
information map.
Default: 600 seconds
◆ LSB_RMSACCT_DELAY=time_seconds
If set on Linux/QsNet hosts, RES waits the specified number of seconds before
exiting to allow LSF and RMS job statistics to synchronize.
If LSB_RMSACCT_DELAY=0, RES waits forever until the database is up to date.
◆ LSB_RMS_MAXNUMNODES=integer
Maximum number of nodes in a Linux/QsNet system. Specifies a maximum value
for the nodes argument to the topology scheduler options specified in:
