PBS (Portable Batch System)
Three important processes:
- pbs_server on the host machine
- pbs_mom’s on each node
- Manage pbs processes (jobs) on the node
- Supply various information (load average, memory usage, # of jobs, etc.) to the server and the schduler
- pbs_sched on the host
- Schedule the jobs (advisor to the server)
- Can collect information of jobs etc. from the server and that of each node from each pbs_mom.
- Scheduling policy is defined in a code of C, BaSL or Tcl by the administrator of the site.
