command to scheduler canceling job job_id

In a similar way, you can define what do to for deleting a job, and what to do for

canceling and deleting tasks.

Delete or Cancel a Running Job

After your functions are written, you set the appropriate properties of the cluster object

with handles to your functions. The corresponding cluster properties are:

• CancelJobFcn

• DeleteJobFcn

• CancelTaskFcn

• DeleteTaskFcn

You can set the properties in the Cluster Profile Manager for your cluster, or on the

command line:

c = parcluster('MyGenericProfile');

% set required properties

c.CancelJobFcn = @myCancelJob

c.DeleteJobFcn = @myDeleteJob

c.CancelTaskFcn = @myCancelTask

c.DeleteTaskFcn = @myDeleteTask

Continue with job creation and submission as usual.

j1 = createJob(c);

for ii = 1:n

t(ii) = createTask(j1,...)

end

submit(j1)

While the job is running or queued, you can cancel or delete the job or a task.

This command cancels the task and moves it to the finished state, and triggers execution

of myCancelTask, which sends the appropriate commands to the scheduler:

cancel(t(4))

This command deletes job data for j1, and triggers execution of myDeleteJob, which

sends the appropriate commands to the scheduler:

1 2 ... 239 240 241 242 243 244 245 246 247 248 249 ... 655 656
