Parallel computing can help you to solve big computing problems
in different ways. MATLAB® and Parallel Computing Toolbox™ provide
an interactive programming environment to help tackle your computing
tasks. If your code runs too slowly, you can profile it, vectorize
it, and use built-in MATLAB parallel computing support. Then
you can try to accelerate your code by using
multiple MATLAB workers in a parallel pool. If you have big data,
you can scale up using distributed arrays or
You can also execute a task without waiting for it to complete, using
so that you can carry on with other tasks. You can use different types
of hardware to solve your parallel computing problems, including desktop
computers, GPUs, clusters, and clouds.
|Run function on parallel pool worker|
|Array stored on GPU|
|Access elements of distributed arrays from client|
|Run MATLAB script or function on worker|
|Create parallel pool on cluster|
|Start counting bytes transferred within parallel pool|
|Read how many bytes have been transferred since calling
