parallel.Worker

Access parallel worker information

Constructors

• getCurrentWorker in the workspace of the MATLAB worker.

• In the client workspace, a parallel.Worker object is available from:

  • The Workers property of a parallel.Pool object. (since R2025a)

  • The Worker property of a parallel.Task object.

Container Hierarchy

Children	none

Description

A parallel.Worker object provides access to the MATLAB worker session that executes a task as part of a job. The job can be an interactive parallel pool job or a batch job.

Types

Worker Type	Description
parallel.cluster.MJSWorker	MATLAB® worker on MATLAB Job Scheduler cluster
parallel.cluster.CJSWorker	MATLAB worker on CJS cluster
parallel.ThreadWorker	MATLAB thread worker (since R2025a)

Methods

There are no methods for a parallel.Worker object other than generic methods for any objects in the workspace, such as delete, etc.
