I see, but i have some doubts the result of clGetDeviceInfo(CL_DEVICE_MAX_MEM_ALLOC_SIZE) takes into account the memory available in GPU RAM. i feel it's more like a static value that never change. it...
View ArticleRe: Maximum memory block size allocable
yes it is static value. if you pass buffer as kernel argument or target of clEnqueueWrite/Copy() you can assume that it was allocated in the device memory which queue is used. there is no way to get...
