CPU & GPU working at the same time...

Accelerated Computing CUDA CUDA Programming and Performance

Does CUDA support the function that we could
make GPU and CPU working seperately at the same time…?

Thanks~ :) !

I dont know if CUDA support it or not… but i think you can use multithread (Or OpenMP) to do that! One thread call for GPU, another thread using CPU to calculate!

Generaly computations on the gpu are asynchronous, so as long as you don’t call cuCtxSynchronize() gpu and cpu work at the same time.
Rewriting kernel calls using some lower level API will alow you to choose when to call cuCtxSynchronize(). I guess that there are some examples of such a thing in sdk.
