LSF Version 7.3 - Platform LSF Configuration Reference

lsf.conf
The lsf.conf file controls the operation of LSF.
About lsf.conf
lsf.conf is created during installation and records all the settings chosen when LSF was installed. The lsf.conf file
dictates the location of the specific configuration files and operation of individual servers and applications.
The lsf.conf file is used by LSF and applications built on top of it. For example, information in lsf.conf is used
by LSF daemons and commands to locate other configuration files, executables, and network services. lsf.conf is
updated, if necessary, when you upgrade to a new version.
This file can also be expanded to include application-specific parameters.
Corresponding parameters in ego.conf
When Platform EGO is enabled in LSF Version 7, you can configure some LSF parameters in lsf.conf that have
corresponding Platform EGO parameter names in EGO_CONFDIR/ego.conf (LSF_CONFDIR/lsf.conf is a separate
file from EGO_CONFDIR/ego.conf). If both the LSF and the EGO parameters are set in their respective files, the
definition in ego.conf is used. You must continue to set LSF parameters only in lsf.conf.
When EGO is enabled in the LSF cluster (LSF_ENABLE_EGO=Y), you also can set the following EGO parameters
related to LIM, PIM, and ELIM in either lsf.conf or ego.conf:
•
EGO_DISABLE_UNRESOLVABLE_HOST (dynamically added hosts only)
•
EGO_PREDEFINED_RESOURCES
•
EGO_DAEMONS_CPUS
•
EGO_DEFINE_NCPUS
•
EGO_SLAVE_CTRL_REMOTE_HOST
•
EGO_WORKDIR
•
EGO_PIM_SWAP_REPORT
If EGO is not enabled, you can set these parameters only in lsf.conf.
See Administering Platform LSF for more information about configuring LSF for EGO. See the Platform EGO
Reference for information about ego.conf parameters.
Changing lsf.conf configuration
After making any changes to lsf.conf, run the following commands:
•
lsadmin reconfig to reconfigure LIM
•
badmin mbdrestart to restart mbatchd
If you have installed LSF in a mixed cluster, you must make sure that lsf.conf parameters set on UNIX and Linux
match any corresponding parameters in the local lsf.conf files on your Windows hosts.
Location
The default location of lsf.conf is in /etc. This default location can be overridden when necessary by either the
environment variable LSF_ENVDIR or the command line option -d available to some of the applications.
