Clusters and Clouds

Discover cluster resources and work with cluster profiles

If your computing task is too big for your local computer, you may want to offload your calculation to networked nodes on a computer cluster. This may be a local cluster or a cluster in the cloud. Changes required to run your MATLAB® code on a cluster are often minimal. Use the MATLAB Job Scheduler (MJS) Profile to exploit computer clusters that have MATLAB Distributed Computing Server™ installed.
