The efficient use of the memory system is a key issue for the performance of many applications. A benchmark written with OpenMP is presented that measures several aspects of a shared memory system like ban ,dwidth, memory latency and inter-thread latency. Special focus is on revealing and identifying bottlenecks and possible hierarchies in the main memory system.
