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.

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
