Transferring the IPS-2 Performance Tools into the Supercomputer Environment

IPS-2是一种用于并行和分布式程序的性能测量系统。它允许应用程序程序员度量他们的并行程序（共享内存和分布式），并生成执行概要文件、图形和高级分析。IPS-2目前在VAX、DECstation（基于mips的）和sequential Symmetry计算机上使用，并已用于各种性能任务。这个项目的目标是适应和移植IPS-2到超级计算机环境；特别针对UNICOS下的CRAY Y/MP。在UNICOS下提供IPS-2将允许该系统可用于NSF的几个超级计算机站点。这一努力将把强大的性能工具交到重要的并行程序员手中，即那些编写复杂科学应用程序的程序员。IPS-2应该简化对复杂程序的分析，并更有效地利用硬件和程序员资源。威斯康星IPS-2小组和美国国家科学基金会圣地亚哥超级计算机中心工作人员的结合提供了性能测量经验和Cray UNICOS专业知识，成功地将IPS-2系统转移到更广泛的研究人员。//

IPS-2 is a performance measurement system for parallel and distributed programs. It allows application programmers to measure their parallel programs (both shared-memory and distributed), and produce execution profiles, graphs, and high-level analyses. IPS-2 is in current use on VAX, DECstation (MIPS-based), and Sequent Symmetry computers, and has been used for a wide variety of performance tasks. The goal of this project is to adapt and port IPS-2 to the supercomputer environment; specifically for the CRAY Y/MP under UNICOS. Providing IPS-2 under UNICOS will allow the system to be available to several of the NSF Supercomputer sites. This effort will place powerful performance tools in the hands of an important class of parallel programmers, i.e., those writing sophisticated scientific applications. IPS-2 should simplify the analysis of complex programs, and make more efficient use of both hardware and programmer resources. The combination of the Wisconsin IPS-2 group and the NSF San Diego Supercomputer Center staff provides both the performance measurement experience and the Cray UNICOS expertise to successfully transfer the IPS-2 system to a broader audience of researchers.//
