disp(['Finished task: ' num2str(task.ID)])

Create a job and set its QueuedFcn, RunningFcn, and FinishedFcn properties, using a

function handle to an anonymous function that sends information to the display.

c = parcluster('MyMJS');

j = createJob(c,'Name','Job_52a');

j.QueuedFcn = @(job,eventdata) disp([job.Name ' now ' job.State]);

j.RunningFcn = @(job,eventdata) disp([job.Name ' now ' job.State]);

j.FinishedFcn = @(job,eventdata) disp([job.Name ' now ' job.State]);

Create a task whose FinishedFcn is a function handle to the separate function.

createTask(j,@rand,1,{2,4}, ...

'FinishedFcn',@clientTaskCompleted);

Run the job and note the output messages from both the job and task callbacks.

submit(j)

Job_52a now queued

Job_52a now running

Finished task: 1

Job_52a now finished

To use the same callbacks for any jobs and tasks on a given cluster, you should set these

properties in the cluster profile. For details on editing profiles in the profile manager, see

“Clusters and Cluster Profiles” on page 6-14. These property settings apply to any jobs

and tasks created using a cluster derived from this profile. The sequence is important,

and must occur in this order:

Set the callback property values for the profile in the profile manager.

Use the cluster profile to create a cluster object in MATLAB.

Use the cluster object to create jobs and then tasks.

Set Callbacks in a Cluster Profile

This example shows how to set several job and task callback properties using the profile

manager.

Edit your MJS cluster profile in the profile manager so that you can set the callback

properties to the same values in the previous example. The saves profile looks like this:
