WebFeb 1, 2011 · 2.2.1.1.6. Stream. STREAM is a microbenchmark for measuring data memory system performance without any data reuse. It is designed to miss on caches and exercise data prefetcher and speculative accesses. It uses double precision floating point (64bit) but in most modern processors the memory access will be the bottleneck. Webtimes fewer iterations than steepest descent to reach the same level of accuracy, where Ris the condition number of the curvature at the minimum and is set to (p R1)=(p + 1). …
