Cache Memories and CPU Performance Architecture

Smith在高速缓冲存储器和CPU性能体系结构方面的研究工作主要集中在三个方面：1.研究向量工作负载的行为，以及向量机可以从使用高速缓冲存储器中获益的程度。I初步结果表明，高速缓冲存储器将工作得很好。2.多处理器中缓存一致性的研究。目前的研究方向是分析一些多处理器的踪迹，以了解共享行为，并评估一些多处理器缓存一致性算法的相对性能。该项目正在生成进一步的跟踪，并研究源代码更改对共享行为的影响。3.对多台机器的存储系统的测量，以确定这些存储系统对整体系统性能的影响。

Smith In the area of cache memories and CPU performance architecture the research efforts are directed at three items: 1. A study of the behavior of vector workloads and the extent to which vector machines can be expected to benefit from the use of cache memories. Iinitial results suggest that cache memories would work well. 2. A study of cache consistency in multiprocessors. Current research is directed at analyzing some multiprocessor traces in order to understand sharing behavior, and to evaluate the relative performance of a number of multiprocessor cache consistency algorithms. The project is generating further traces and study the effect of changes in the source code on sharing behavior. 3. The mMeasurement of the memory systems of a number of machines to determine the effect that those memory systems have on overall system performance.
