Cluster with Multiple Clients and MJSs

Local Cluster

A feature of Parallel Computing Toolbox software is the ability to run a local cluster

of workers on the client machine, so that you can run jobs without requiring a remote

cluster or MATLAB Distributed Computing Server software. In this case, all the

processing required for the client, scheduling, and task evaluation is performed on the

same computer. This gives you the opportunity to develop, test, and debug your parallel

applications before running them on your network cluster.

Third-Party Schedulers

As an alternative to using the MJS, you can use a third-party scheduler. This could be

a Microsoft Windows HPC Server (including CCS), Platform LSF scheduler, PBS Pro

scheduler, TORQUE scheduler, or a generic scheduler.

Choosing Between a Third-Party Scheduler and an MJS

You should consider the following when deciding to use a third-party scheduler or the

MATLAB job scheduler (MJS) for distributing your tasks:

• Does your cluster already have a scheduler?

If you already have a scheduler, you may be required to use it as a means of

controlling access to the cluster. Your existing scheduler might be just as easy to use

as an MJS, so there might be no need for the extra administration involved.
