Transferring the IPS-2 Performance Tools into the Supercomputer Environment

IPS-2是一个针对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测量他们的并行程序(包括共享内存和分布式程序)，并生成执行配置文件、图表和高级分析。IPS-2目前在VAX、DECStation(基于MIPS)和Sequent Symmetry型计算机上使用，并已用于各种性能任务。该项目的目标是使IPS-2适应超级计算机环境；特别是用于UNICOS下的Cray Y/MP。在UNICOS下提供IPS-2将允许NSF的几个超级计算机站点使用该系统。这一努力将把强大的性能工具交到一类重要的并行程序员手中，即那些编写复杂科学应用程序的人。IPS-2应该简化复杂程序的分析，并更有效地利用硬件和程序员资源。威斯康星州IPS-2小组和NSF圣地亚哥超级计算机中心工作人员的组合提供了性能测量经验和Cray UNICOS的专业知识，以成功地将向更广泛的研究人员介绍IPS-2系统。//

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.//
