6 Programming Overview

• The Cluster Profile Manager indicates which is the default profile. You can select any

profile in the list, then click Set as Default.

• You can get or set the default profile programmatically by using the

parallel.defaultClusterProfile function. The following sets of commands

achieve the same thing:

parallel.defaultClusterProfile('MyMJSprofile1')

parpool

parpool('MyMJSprofile1')

Create Cluster Object

The parcluster function creates a cluster object in your workspace according to the

specified profile. The profile identifies a particular cluster and applies property values.

For example,

c = parcluster('myMJSprofile')

This command finds the cluster defined by the settings of the profile named

myMJSprofile and sets property values on the cluster object based on settings in the

profile. By applying different profiles, you can alter your cluster choices without changing

your MATLAB application code.

Create Jobs and Tasks

Because the properties of cluster, job, and task objects can be defined in a profile, you

do not have to explicitly define them in your application. Therefore, your code can

accommodate any type of cluster without being modified. For example, the following code

uses one profile to set properties on cluster, job, and task objects:

c = parcluster('myProfile1');

job1 = createJob(c); % Uses profile of cluster object c.

createTask(job1,@rand,1,{3}) % Uses profile of cluster object c.
