MATLAB: Do I receive an error when submitting jobs to HPC Server from a 32-bit Windows client

MATLAB Parallel Server

When attempting to submit a MATLAB Distributed Computer Server job to a cluster setup with HPC Server 2008, I receive the following error:

Error Report:

Error using ==> distcomp.configurableobject.pSetConfiguration at 40

Error when using the 'scheduler' section of the configuration 'hpc':

Failed to use cluster client utilities for version HPCServer2008

I have the HPC client pack installed on this computer and can submit non-MATLAB jobs to the cluster. How can I resolve this issue for MATLAB?

32-bit clients are supported for HPC starting with R2011a. For previous releases, see the winformation below.

Parallel Computing Toolbox only supports job submission to an HPC Server 2008 cluster from 64-bit Windows clients. In order to submit to this type of cluster, it must be done from a 64-bit Windows client. It is possible to submit from a 32-bit client, but this must be done by setting the "ClusterVersion" of the configuration to ccs. This allows the jobs to submit using the old CCS mode, which does not use the advanced HPC functions.

NOTE: Starting in R2019a the following name changes occurred:
MATLAB Distributed Computing Server was renamed to MATLAB Parallel Server
mdce_def was renamed to mjs_def
mdce binary was renamed to mjs

MATLAB: How to take advantage of useParallel option for a remote job running on workers in a MDCS cluster

1. In order to use parallel pool with the cluster, please consider using the 'batch' function procedure to submit the jobs into cluster:

https://www.mathworks.com/help/distcomp/batch.html

When using the 'batch' command, it has the option to specify the number of workers to be used in addition to the job itself. Please refer to the example below:

c=parcluster('profile');
j = batch(c,@scriptUseParallel, 'Pool', 2);
wait(j);
diary(j);
Y2=fetchOutputs(j);

2. In the cluster setup, please consider to configure each machine to have the same number of workers as the number of cores.

Therefore each core can be started with a MATLAB process and being utilized by the batch job.

MATLAB: How does the licensing work for jobs submitted to the MATLAB Distributed Computing Server (MDCS)

The licensing for a job submitted to an MDCS cluster is determined by the client. When you submit a job from a client with the Parallel Computing Toolbox, it carries the licensing information of what products that client is able to use. Any product that the client can use in MATLAB can also be used on the MDCS cluster in a submitted job.

For example, if you are have a license for MATLAB and the Statistics Toolbox, you can only successfully submit jobs to an MDCS cluster if the job uses nothing more than MATLAB and the Statistics Toolbox. If your submitted code uses the Database Toolbox, you will receive an error during job submission due to inadequate licensing.
