Abstract :
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
