WebOpenCL Memory Hierarchy 8 ... Local memory is divide into banks. Successive 32-bit words assigned to successive banks Number of banks = 16 for CC 1.x R/W different banks can be performed simultaneously. Bank conflict: two R/W fall in the same bank, the access will be serialized. WebLocal Memory Usage. One typical GPU-targeted optimization uses local memory for caching of intermediate results. For CPU, all OpenCL™ memory objects are cached by hardware, so explicit caching by use of local memory just introduces unnecessary (moderate) overhead. Tips for Auto-Vectorization Avoid Extracting Vector Components.

Web2 de mar. de 2024 · I wrote two OpenCL kernels that calculate the box filter: one using local memory and the other one without the local memory. 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.
