DEFAULT_USER_GROUP=default_user_group
When DEFAULT_USER_GROUP is defined, all submitted jobs must be associated with a user group. Jobs without a user group specified will be associated with default_user_group, where default_user_group is a group configured in lsb.users and contains all as a direct member. DEFAULT_USER_GROUP can only contain one user group.
If the default user group does not have shares assigned in a fairshare queue, jobs can still run from the default user group and are charged to the highest priority account the user can access in the queue. A job submitted to a user group without shares in a specified fairshare queue is transferred to the default user group where the job can run. A job modified or moved using bmod or bswitch may similarly be transferred to the default user group.
The default user group should be configured in most queues and have shares in most fairshare queues to ensure jobs run smoothly.
Jobs linked to a user group, either through the default_user_group or a user group specified at submission using bsub -G, allow the user group administrator to issue job control operations. User group administrator rights are configured in the UserGroup section lsb.users, under GROUP_ADMIN.
When DEFAULT_USER_GROUP is not defined, jobs do not require a user group association.
After adding or changing DEFAULT_USER_GROUP in lsb.params, use badmin reconfig to reconfigure your cluster
Not defined. When a user submits a job without explicitly specifying user group name, LSF does not associate the job with any user group.
