Schedulers, Workers, a nd Clients

The optional MJS can run on any machine on the network. The MJS runs

jobs in the order in which they are submitted, unless any jobs in its queue are

promoted, demoted, canceled, or destroyed.

Each worker receives a task of the running job from the MJS, executes the

task, returns the result to the MJS, and then receives another task. When

all tasks for a running job have been assigned to workers, the MJS starts

running the next job with the next available worker.

A MAT LAB Distributed Computing Server network configuration usually

includes many workers that can all execute tasks simultaneously, speeding

up ex ecutio n of large MATLAB jobs. It is generally not important which

worker executes a specific task. Each worker evaluates tasks one at a time,

returning the results to the MJS. The MJS then returns the results of all the

tasks in the job to the client session.

Note For testing your application locally or other purposes, you can configure

a single computer to host the client, workers, and M JS. You can also have

more than one worker session or more than one MJS session on a machine.
