promote

Promote job in MJS cluster queue

Syntax

promote(c,job)

Arguments

c

The MJS cluster object that contains the job.

job

Job object promoted in the queue.

Description

promote(c,job) promotes the job object job, that is queued in the MJS cluster c.

If job is not the first job in the queue, promote exchanges the position of job and the previous job.

Examples

Create and submit multiple jobs to the cluster identified by the default cluster profile, assuming that the default cluster profile uses an MJS:

c = parcluster();
pause(c) % Prevent submissions from running.

j1 = createJob(c,'Name','Job A');
j2 = createJob(c,'Name','Job B');
j3 = createJob(c,'Name','Job C');
submit(j1);submit(j2);submit(j3);

Promote Job C by one position in its queue:

promote(c,j3)

Examine the new queue sequence:

[pjobs,qjobs,rjobs,fjobs] = findJob(c);
get(qjobs,'Name')
    'Job A'
    'Job C'
    'Job B'

Tips

After a call to promote or demote, there is no change in the order of job objects contained in the Jobs property of the MJS cluster object. To see the scheduled order of execution for jobs in the queue, use the findJob function in the form [pending queued running finished] = findJob(c).
