In addition to Parallel Computing Toolbox™ providing a local cluster of workers for your client machine, MATLAB® Distributed Computing Server™ software allows you to run as many MATLAB workers on a remote cluster of computers as your licensing allows..
Most MathWorks products let you code in such a way as to run applications in parallel. For example, Simulink models can run simultaneously in parallel, as described in Run Parallel Simulations. MATLAB Compiler™ software lets you build and deploy parallel applications, as shown in Deploy Applications Created Using Parallel Computing Toolbox.
Several MathWorks products now offer built-in support for the parallel computing products, without requiring extra coding. For the current list of these products and their parallel functionality, see:
