MATLAB: Do I receive the message “Could not start the cluster” when trying to start a cluster in MATLAB Cloud Center

MATLAB

Why do I receive the message "Could not start the cluster" when trying to start a cluster in MATLAB Cloud Center?

Best Answer

This error indicates that the version of the MATLAB Parallel Server is not compatible with the Cloud Center service. MATLAB Parallel Server releases are supported in the Cloud Center for two years, rotating at the annual A and B releases. Please create a new MATLAB Parallel Server cluster to continue using the Cloud Center web application for MATLAB Parallel Server management.

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

It is possible to submit using your MATLAB Parallel Server EC2 profile when running MATLAB without a display. In order to do so, however, you must first launch normally and cache your login credentials.

Launch MATLAB
Submit using your EC2 profile (or run a validation for this profile)
When prompted to enter your MathWorks credentials, make sure to check the box labelled
Once submission or validation finishes, close MATLAB
Restart MATLAB without a display

You should now be able to submit to the cluster running on EC2 without use of the MATLAB desktop.

MATLAB: Can I not validate the Amazon Cloud cluster profile

To fix the above error, you may potentially have to take several steps.

Firstly, make sure that your version of MATLAB and the version of the MATLAB Parallel Server that is running on the Amazon Cloud are the same release - the error is misleading, but release missmatch could be the issue.

To check what version your installation of MATLAB is, run the below in the MATLAB command window:

ver

To check what version your MATLAB Parallel Server cluster is, log into your Amazon cloud account(www.mathworks.com/cloudcenter) and click on your cluster name. After doing that, click on "More Details" and you can see the MATLAB Version in the drop down.
