Specify the group name under the GROUP_NAME column.
External user groups must also be defined in the egroup executable.
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.
Note:
If ENFORCE_UG_TREE=Y is defined in lsb.params, all user groups must conform to a tree-like structure, and a user group can appear in GROUP_MEMBER once at most. The second and subsequent occurence of a user group in GROUP_MEMBER is ignored.
Optional: To enable hierarchical fairshare, specify share assignments in the USER_SHARES column.
Save your changes.
Run badmin ckconfig to check the new user group definition. If any errors are reported, fix the problem and check the configuration again.
