memory benchmark: use local memory as default operation

During several CPUs writing to a small memory block(Ex, 1K), the CPUs need to invalid CPU cache and trigger cache-to-cache synchronous communication. It's a little difficult to find the root cause of this scenario. Use local memory to avoid this case, make it easy to use. Signed-off-by: zhenwei pi <[email protected]>
