WebMemory Size Limitations Private – if too many registers are used per thread, will start to spill into thread-visible main memory Global – limited by the amount of main memory of device Constant – device limited, usually 64KB per device Local – device limited, usually 32KB per compute-unit Movement between memory spaces Web2 de mar. de 2024 · The performance of the kernel that does not use the local memory is way better than the one that uses local memory. The one with the local memory takes 30ms and the one without takes 19ms. I thought it should be the other way around. #define FILTER_RADIUS (3) #define FILTER_SIZE (2*FILTER_RADIUS + 1) #define …
