8.3. Performing Kernel Computations Using Constant, Local or Private Memory

To optimize memory access efficiency, minimize the number for global memory accesses by performing your OpenCL™ kernel computations in constant, local, or private memory.

To minimize global memory accesses, you must first preload data from a group of computations from global memory to constant, local, or private memory. You perform the kernel computations on the preloaded data, and then write the results back to global memory.
