Administering Platform LSF - SAS

LSF User Groups
LSF User Groups
You can define an LSF user group within LSF or use an external executable to
retrieve user group members.
Use bugroup to view user groups and members, use busers to view all users
in the cluster.
Where to use LSF user groups
LSF user groups can be used in defining the following parameters in LSF
configuration files:
◆ USERS in lsb.queues for authorized queue users
◆ USER_NAME in lsb.users for user job slot limits
◆ USER_SHARES (optional) in lsb.hosts for host partitions or in
lsb.queues for queue fairshare policies
If you are using existing OS-level user groups instead of LSF-specific user
groups, you can also specify the names of these groups in the files mentioned
above.
Configuring user groups
1 Log in as the LSF administrator to any host in the cluster.
2 Open lsb.users.
3 Add the UserGroup section if it does not exist.
Begin UserGroup
GROUP_NAME GROUP_MEMBER USER_SHARES
financial (user1 user2 user3) ([user1, 4]
[others, 10])
system (all) ([user2, 10]
[others, 15])
regular_users (user1 user2 user3 user4) -
part_time_users (!) -
End UserGroup
4 Specify the group name under the GROUP_NAME column.
External user groups must also be defined in the egroup executable.
5 Specify users in the GROUP_MEMBER column.
For external user groups, put an exclamation mark (!) in the
GROUP_MEMBER column to tell LSF that the group members should be
retrieved using egroup.
6 (Optional) To enable hierarchical fairshare, specify share assignments in
the USER_SHARES column.
7 Save your changes.
8 Run badmin ckconfig to check the new user group definition. If any
errors are reported, fix the problem and check the configuration again.
9 Run badmin reconfig to reconfigure the cluster.
