Pending Jobs Not Being Dispatched

Sometimes a pending job is obviously capable of being run, but the job does not get dispatched. To diagnose the reason, the grid engine system offers a pair of utilities and options, qstat -j job-id and qalter -w v job-id.

This command lists the reasons why a job is not dispatchable in principle. For this purpose, a dry scheduling run is performed. All consumable resources, as well as all slots, are considered to be fully available for this job. Similarly, all load values are ignored because these values vary.

Job or Queue Reported in Error State E

Job or queue errors are indicated by an uppercase E in the qstat output.

A job enters the error state when the grid engine system tries to run a job but fails for a reason that is specific to the job.

A queue enters the error state when the grid engine system tries to run a job but fails for a reason that is specific to the queue.

The grid engine system offers a set of possibilities for users and administrators to gather diagnosis information in case of job execution errors. Both the queue and the job error states result from a failed job execution. Therefore the diagnosis possibilities are applicable to both types of error states.

From queue information you get job information. After that you need to discover what's wrong with particular job. See Monitoring and Controlling Jobs

Use qstat to show the current status of the queues and the jobs associated with the queues.

Controlling Queues With qmod

You can use the qmod command to suspend and resume queues. You can also use qmod to disable and enable queues.

The following commands illustrate how to use qmod:

% qmod -s q-name
% qmod -us -f q-name1, q-name2
% qmod -d q-name
% qmod -e q-name1, q-name2, q-name3

qmod -s suspends a queue. qmod -us -f resumes (unsuspends) two queues. qmod -d disables a queue. qmod -e enables three queues.

The -f option forces registration of the status change in sge_qmaster when the corresponding sge_execd is not reachable, for example, due to network problems.

Suspending and resuming queues as well as disabling and enabling queues requires queue owner permission, manager permission, or operator permission. See Managers, Operators, and Owners.


Note -

You can use qmod commands with crontab or at jobs.
