Using the Urgency Policy to Assign Job Priority

The urgency policy can be used in combination with two other job priority specifications:

• The number of tickets assigned by the functional, share-based, and override policies

• A priority value specified by the qsub –p command

A job can be assigned an urgency value, which is derived from three sources:

• The job's resource requirements

• The length of time a job must wait before the job runs

• The time at which a job must finish running, that is, the job's deadline

The administrator can separately weight the importance of each of these sources in order to arrive at a job's overall urgency value. For more information, see Chapter 5, Managing Policies and the Scheduler, in Sun N1 Grid Engine 6.1 Administration Guide.

Figure 1–2 shows the correlation among policies.
