The Job Scheduler

Why do we need a scheduler / why can't I submit jobs directly to compute nodes?

• The job scheduler is essential to making your jobs run efficiently across a broad workload.
• Not only does the scheduler ensure your job runs uninterrupted, it also makes sure your job has all the resources you requested.
• The scheduler allows for more complex submission schemes, such as job arrays and chaining jobs which enable larger and more complicated jobs.

What technology does PACE use for its scheduler and resource manager?

• Currently PACE uses the Moab scheduler along with the Torque resource manager.
