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.
