College of Engineering and ComputerScience 1-1-1994 PASSION Runtime Library for Parallel I / O

We are developing a compiler and runtime support system called PASSION: Parallel And Scalable Software for Input-Output. PASSION provides software support for I/O intensive out-of-core loosely synchronous problems. This paper gives an overview of the PASSION Runtime Library and describes two of the optimizations incorporated in it, namely Data Prefetching and Data Sieving. Performance improvements provided by these optimizations on the Intel Touchstone Delta are discussed, together with an out-of-core Median Filtering application.

我们正在开发一个名为PASSION（用于输入 - 输出的并行可扩展软件）的编译器和运行时支持系统。PASSION为I/O密集型核外松散同步问题提供软件支持。本文概述了PASSION运行时库，并描述了其中包含的两种优化，即数据预取和数据筛选。讨论了这些优化在英特尔Touchstone Delta上所带来的性能提升，同时还介绍了一个核外中值滤波应用。
