Configure parallel fairshare

About this task

To configure parallel fairshare so that the number of CPUs is considered when calculating dynamic priority for queue-level user-based fairshare:

LSB_NCPU_ENFORCE does not apply to host-partition user-based fairshare. For host-partition user-based fairshare, the number of CPUs is automatically considered.


  1. Configure fairshare at the queue level.
  2. Enable parallel fairshare: LSB_NCPU_ENFORCE=1 in lsf.conf.
  3. Run the following commands to restart all LSF daemons:
    # lsadmin reconfig
    # lsadmin resrestart all
    # badmin hrestart all
    # badmin mbdrestart
