createJob

Create independent job on cluster

Syntax

obj = createJob(cluster)
obj = createJob(...,'p1',v1,'p2',v2,...)
job = createJob(...,'Profile','profileName',...)


Arguments

obj	The job object.
cluster	The cluster object created by parcluster.
p1, p2	Object properties configured at object creation.
v1, v2	Initial values for corresponding object properties.

Description

obj = createJob(cluster) creates an independent job object for the identified cluster.

The job’s data is stored in the location specified by the cluster’s JobStorageLocation property.

obj = createJob(...,'p1',v1,'p2',v2,...) creates a job object with the specified property values. For a listing of the valid properties of the created object, see the parallel.Job object reference page. The property name must be a character vector, with the value being the appropriate type for that property. In most cases, the values specified in these property-value pairs override the values in the profile; but when you specify AttachedFiles or AdditionalPaths at the time of creating a job, the settings are combined with those specified in the applicable profile. If an invalid property name or property value is specified, the object will not be created.

job = createJob(...,'Profile','profileName',...) creates an independent job object with the property values specified in the profile 'profileName'. If a profile is not specified and the cluster has a value specified in its 'Profile' property, the cluster’s profile is automatically applied. For details about defining and applying profiles, see Discover Clusters and Use Cluster Profiles.

Examples

Example 2. Create and Run a Basic Job

Construct an independent job object using the default profile.

c = parcluster
j = createJob(c);

Add tasks to the job.

for i = 1:10
    createTask(j,@rand,1,{10});
end

Run the job.

submit(j);

Wait for the job to finish running, and retrieve the job results.

wait(j);
out = fetchOutputs(j);

Display the random matrix returned from the third task.

disp(out{3});

Delete the job.

delete(j);

Example 3. Create a Job with Attached Files

Construct an independent job with attached files in addition to those specified in the default profile.

c = parcluster
j = createJob(c,'AttachedFiles',...
        {'myapp/folderA','myapp/folderB','myapp/file1.m'});
