The column relop defines the relational operator used to compute whether a queue or a host meets a user request. The comparison that is executed is as follows:

User_Request     relop     Queue/Host/... -Property

If the result of the comparison is false, the user's job cannot be run in the queue or on the host. For example, let the queue q1 be configured with a soft CPU time limit of 100 seconds. Let the queue q2 be configured to provide 1000 seconds soft CPU time limit. See the queue_conf(5) and the setrlimit(2) man pages for a description of user process limits.

The columns consumable and default are meaningful for the administrator to declare consumable resources. See "Consumable Resources" in N1 Grid Engine 6 Administration Guide.

The user requests consumables just like any other attribute. The grid engine system internal bookkeeping for the resources is different, however.

Assume that a user submits the following request:

% qsub -l s_cpu=0:5:0 nastran.sh

The s_cpu=0:5:0 request asks for a queue that grants at least 5 minutes of soft limit CPU time. Therefore only queues providing at least 5 minutes soft CPU runtime limit are set up properly to run the job. See the qsub(1) man page for details on the syntax.


Note - The grid engine software considers workload information in the scheduling process only if more than one queue or host can run a job.
