I attempt to use opcncl to imporve peroformance of my program. but i find two questions.
first, initialize OpenCL i mean getdevice, createprogram, buildprogram...cost about more than 300ms, towards me 300ms is too much long, how to shorten initialization time?
second, my program is about image processing, so big image memory transfer between gpu and host is such a headache, so any good idea about memory copy?
thanks for your answer, sorry for my english.
