A performance evaluation of cache injection in bus-based shared memory multiprocessors

摘要

Bus-based shared memory multiprocessors with private caches and snooping write-invalidate cache coherence protocols are dominant form of small-to medium-scale parallel machines today. In these systems, the high memory latency poses the major hurdle in achieving high performance. One way of cope with this problem is to use various techniques for tolerating high memory latency. Software-controlled cache prefetching and data forwarding are two widely used techniques for tolerating high memory latency in scalable cache-coherent shared memory multiprocessors.
