Working in an Interactive Parallel Environment

Parallel Computing Toolbox extends the MATLAB interactive environment, letting you use the familiar MATLAB environment for prototyping and developing task- and data- parallel applications. The matlabpool command allocates a set of dedicated computational resources for you. It connects your MATLAB session to a pool of MATLAB workers that can run either locally on your desktop or on a computer cluster. It sets up an interactive parallel execution environment in which you can execute your parallel MATLAB code from the MATLAB command prompt and retrieve results immediately as computations finish. In this environment parallel programming constructs, such as parfor and spmd, automatically detect the presence of workers and distribute computations and data between your MATLAB session and the workers.

The Parallel Command Window (pmode) is an extension of the MATLAB Command Window that sets up a data-parallel execution environment in which you can use distributed arrays, associated parallel functions, and message-passing functions. Commands issued at the parallel prompt are executed simultaneously on all participating workers and results are accessible immediately, enabling you to better track application behavior across your multiprocessor system at each step. Commands can be collected into a MATLAB function and submitted for offline execution.
