i use the new options in loops
parforsome code,,,someimage=gpuarray(image)process(someimage)end
1) it slows down pc 2) it takes all memory 3) somtimes it works slower than normal loop and image in cpu
so when it is usful to use parfor (images i suppose transmited all fors if it is array) and gpu not alwayes fast is it the communication gpu cpu that takes the time?
