LSF Version 7.3 - Platform LSF Configuration Reference

Configuration to enable external host and user groups
To enable the use of external host and user groups, you must
•
Define the host group in lsb.hosts, or the user group in lsb.users, and put an
exclamation mark (!) in the GROUP_MEMBER column.
•
Create an egroup executable in the directory specified by the parameter
LSF_SERVERDIR in lsf.conf. LSF does not include a default egroup; you should write
your own executable to meet the requirements of your site.
•
Run the command badmin reconfig to reconfigure the cluster and import your external
host and user groups.
Define an external host or user group
External host groups are defined in lsb.hosts, and external user groups are defined in
lsb.users. Your egroup executable must define the same group names that you use in the
lsb.hosts and lsb.users configuration files.
