<p>Many parallel applications need to access large amounts of data. In such applications, the I/O performance can play a significant role in the overall time to completion. Although I/O is always much slower than computation, it is still possible to achieve good I/O performance in parallel applications by using a combination of sufficient amount of high-speed I/O hardware, appropriate file-system software, appropriate API for I/O, a high-performance implementation of the API, and by using that API the right way. We explain these points in further detail. Morgan Kaufmann is pleased to present material from a preliminary draft of CRPC Handbook of Parallel Computing, edited by J. Dongarra, I. Foster, G. Fox, K. Kennedy, L. Torczon, and A. White, (c) Copyright 2001 Morgan Kaufmann Publishers.
