摘要
并行处理是获得高性能计算的有效而必要的手段,因而成为新一代计算机的结构特征.目前并行处理技术已经有了很大发展,但对并行处理的性能评价还是不完善的.加速比是用来描述并行处理的效果的,但以往的加速比公式并没有考虑cache的影响,这就存在一定的缺陷,因为cache对整个系统的性能有很大的影响.本文提出了考虑cache开销的加速比模型,并从理论和实际应用方面讨论了cache对加速比的影响.
Parallel processing, an effective approach to further improve the performance of computers, has become the main trend of high-performance computing.Speedup is usually used to reflect the effect of parallel processing, but the existingspeedup models do not consider the affect of cache. The speedup models considering the overhead of cache are proposed and the affect of cache to several speedupmodels is analyzed in detail in this paper.
