Hi everyone, I will make number of simulations next week, and I would like to know if I can make the for loop faster. I already use parfor actually in pretty straight forward coding algorithm in a mimo communication system model. I heard that maybe gpu can be added to make the iteration faster. Does anyone have an idea? Otherwise, I will keep my computer to finish my simulations almos 2 weeks non-stop. Best regards Samet

It depends on what your computation looks like. The GPU can accelerate many of the usual vectorized operations. A.*B, A+B, A./B, etc... can be made faster as long as A and B can be kept on the GPU across all iterations. However, if you have to pull data back from the GPU to the host, at every iteration, it can introduce communication overhead that could make it all non-worthwhile.
