Long computation time on GPUs #15

Open MariusKlug opened 1 year ago

MariusKlug commented 1 year ago

I compared the computation time of the nonlinear EEG measures and found something interesting: On my gaming machine (Ryzen 5800x, 32gb RAM, and RTX 3080) the computation time with just parallel computing, but no GPU computation was actually much lower. It took about 1h for method 2 without GPU, but 2h 10min when utilizing GPU computation. I repeated this measure twice with similar results. Perhaps the GPU array allocation can be made more efficient...
