Using Parallel Computing Toolbox™ Software

Using Parallel Computing Toolbox Software

A typical Parallel Computing Toolbox client s ession includes the following

steps:

1 Find a cluster — Your ne twork m ay h ave one or more MJS available

(but usually only one scheduler). The function you use to find an MJS or

scheduler creates an object in your current MATLAB session to represent

the MJ S or scheduler that will run your job.

2 Create a Job — You create a job to hold a collection of tasks. The job exists

on the MJS (or scheduler’s data location), but a job object in the local

MATLAB session represents that job.

3 Create Tasks — You create tasks to add to the job. Each task of a job can

be represented by a task object in your local MATLAB sessio n.

4 Submit a Job to the Job Queue for Execution — W hen your job has all its

tasks defined, you submit it to the queue in the MJS or scheduler. The

MJS or scheduler distributes your job’s tasks to the worker sessions for

evaluation. When all of the workers are completed with the job’s tasks,

the job moves to the finished state.

5 Retrieve the Job’s Results — The resulting data from the evaluation of the

job is av a ilable as a property value of each task object.

6 Des troy the Job — When the job is com plete and all its results are gathered,

you can destroy the job to free memory resources.
