I am wondering if my code will benefit from a speedup from a GPU (i.e. wondering if I should buy one), and realized that I don't know if the Global Optimization Toolbox is GPU compliant?

Thanks! Stefan

It is not. Your best bet is Jacket.

Please read http://www.mathworks.com/help/toolbox/gads/bsc7xh9-1.html

That document shows how the various commands can be used with parallelism options.

I do not know if the GPU can be accessed from multiple workers at the same time (I haven't studied the GPU.) I have, however, read that only one GPU can be accessed per MATLAB instance (parallel workers are separate instances, I gather.)

Some of the routines (such as MultiStart) wrap around existing commands, with those commands invoking user functions to do the calculations. The user functions can invoke GPU calculations (provided that you have the Parallel Computing Toolbox).

If, however, you are using the options that invoke parallel instances, then I have no information at this time as to whether the parallel instances can simultaneously use the same GPU.

Your question is not clear as to what model of GPU usage you are hoping for ?

I am hoping to be able to run patternsearch on the GPU instead of on a few different worker threads. I suppose that's asking a bit much of GPU computing (as it does not support a lot of operations).

Thanks for the reply once again!
