How do I validate my MATLAB cluster when I do not have access to a GUI?

The machine I need to run cluster validation from does not have access to the MATLAB GUI. How do I manually validate my MATLAB cluster?

If you have access to a GUI in your client MATLAB please follow these steps

instead: http://www.mathworks.com/matlabcentral/answers/1590004-how-do-i-validate-my-parallel-cluster-profile-in-matlab

Only use these steps if you do not have access to a GUI in your client MATLAB.

The following commands work whether you are validating a local profile or a MATLAB Parallel Server profile. Please make sure you are validating the correct profile before proceeding and that you replace "name_of_profile" with the name of the profile you want to manually validate.

In order to place MATLAB in verbose mode run the following command within the MATLAB command Window. 

setSchedulerMessageHandler(@disp)

Then run each of the following jobs:

 

Independent (Batch) Job

cluster = parcluster('name_of_profile');
job = createJob (cluster);
createTask(job, @sum, 1, {[1 1]});
submit(job);
wait(job);
out = fetchOutputs(job)

 

SPMD Job (Communicating Batch Job)

cluster = parcluster('name_of_profile');
job = createCommunicatingJob(cluster, 'Type', 'spmd') ;
createTask(job, @labindex, 1, {});
submit(job);
wait(job);
out = fetchOutputs(job)

 

Parpool (Interactive Communicating Job)

parpool('name_of_profile', 2)

 

If you are using MATLAB R2013a or older to run a MATLAB interactive job, use the "matlabpool" command:

 

Matlabpool (Interactive Communicating Job)

matlabpool('name_of_profile', 2)
