DEFAULT_USER_GROUP

Syntax

DEFAULT_USER_GROUP=default_user_group

Description

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 fair share 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 fair share 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.

Note: The default user group should be configured in most queues and have shares in most fair share 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

Default

Not defined. When a user submits a job without explicitly specifying user group name, LSF does not associate the job with any user group.
