Job Priority

The job scheduling definition may include a specification of an internal priority for the job. When competing for the same resource, jobs with higher priority take precedence over jobs with lower priority. Users can also assign a "critical path" priority to jobs that must be submitted with the least delay possible. A job with critical path priority is allocated required resources as the resources become available. When all its required resources are available, the job is submitted.

Noncritical jobs are not allocated resources until all required resources are available at the same time.
