摘要

共享内存多处理器中引用局部性的利用是当前并行处理中最重要的问题之一。局部性可以在几个级别进行管理:硬件、操作系统、编译器的运行时环境和用户级别。在本文中，我们研究了在操作系统级别上利用局部性的问题及其与编译器和体系结构的交互。基于对实际应用的跟踪驱动模拟，我们的主要结论是，只有在所有三个层次合作的情况下，局部性的利用才是有效的。

Trace-driven simulation of data alignment and other factors affecting update and invalidate based coherent memory

The exploitation of locality of reference in shared memory multiprocessors is one of the most important problems in parallel processing today. Locality can be managed in several levels: hardware, operating system, runtime environment of the compiler, and user level. In this paper we investigate the problem of exploiting locality at the operating system level and its interactions with the compiler and the architecture. Our main conclusion, based on trace-driven simulations of real applications, is that exploitation of locality is effective only if all three levels cooperate.<>
