6-27

Create and save a callback function clientTaskCompleted.m on the path of the

MATLAB client, with the following content. (If you created this function for the previous

example, you can use that.)

function clientTaskCompleted(task,eventdata)

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

Create objects for the cluster, job, and task. Then submit the job. All the callback

properties are set from the profile when the objects are created.

c = parcluster('MyMJS');

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

createTask(j,@rand,1,{2,4});

submit(j)

Job_52a now queued

Job_52a now running

Finished task: 1

Job_52a now finished

Tips

• You should avoid running code in your callback functions that might cause conflicts.

For example, if every task in a job has a callback that plots its results, there is no
