Parallel Computing Concepts

A job is some large operation that you need to perform in your M ATL AB

session. A job is broken down into s egm ents called tasks.Youdecidehowbest

to divide your jo b into tasks. You could divide your j ob into identical tasks,

but tasks do not have to be identical.

The MAT L A B session in which th e jo b and its tasks are defined is called the

client session. Often, this is on the machine where you program MATLAB.

The client uses Parallel Computing Toolbox software to perform the definition

of jobs and tasks. The MATLAB D istributed Computing Server product

performs the execution of your job by evaluating e ach of its tasks and

returning the res ult to your client session.

Parallel Computing Toolbox software allows you to run as many as 12

MATLAB workers on your local machine in addition to your MATLAB client

session. MATLAB Distributed Computing Server software allows you to run

as many MATLAB workers on a remote cluster of computers as your licensing

allows. You can also u se MATLAB Distributed Computing Server to run

workers on your client machine if you want to run more than 12 local workers.

The MATLAB job schedule r (MJS) is the part of the server software that

coordinates the execution of jobs and the evaluation of their tasks. The MJS

distributes the tasks for evaluation to the server’s individual MATLAB

sessions called workers. Use of the MJS is optional; the distribution of

taskstoworkerscanalsobeperformedby a third-party scheduler, such as

Window HPC Server (including CCS), a Platform LSF scheduler, or a PBS

Pro scheduler.
