Selecting the cluster scheduler is an important decision and significantly affects cluster utilization, responsiveness, availability, and intelligence. The default TORQUE scheduler, pbs_sched, is very basic and will provide poor utilization of your cluster's resources. Other options, such as Maui Scheduler or Moab Workload Manager, are highly recommended. If you are using Maui or Moab, refer to the Moab-PBS Integration Guide. If using pbs_sched, simply start the pbs_sched daemon.
If you are installing Moab Cluster Suite, TORQUE and Moab were configured at installation for interoperability and no further action is required.
