摘要

本文研究了在多处理器上执行的一些科学应用程序(Perfect基准测试的一个子集)的I/O行为。本研究的目的是探索大型科学应用程序的各种I/O访问模式，并了解这种观察到的行为对I/O子系统体系结构的影响。程序的I/O行为由它对I/O子系统施加的需求来表征。可以观察到，对于所考虑的应用程序来说，隐式I/O或分页不是主要问题，I/O问题主要体现在程序中完成的显式I/O中。研究了I/O访问的各种特性，并讨论了它们对体系结构设计的影响

A study of I/O behavior of Perfect benchmarks on a multiprocessor

The I/O behavior of some scientific applications, a subset of Perfect benchmarks, executing on a multiprocessor is studied. The aim of this study is to explore the various patterns of I/O access of large scientific applications, and to understand the impact of this observed behavior on the I/O subsystem architecture. I/O behavior of the program is characterized by the demands it imposes on the I/O subsystem. It is observed that implicit I/O or paging is not a major problem for the applications considered and the I/O problem is mainly manifest in the explicit I/O done in the program. Various characteristics of I/O accesses are studied, and their impact on architecture design is discussed.<>
