U.S.-Polish Collaborative Research on Efficient System Support for Data-Parallel MIMD

小行星9401222 这个美国-波兰联合合作研究基金，研究"有效的系统支持数据并行MIMD"是博士艾萨克D。加州尔湾大学信息与计算机科学系的Scherson和华沙大学信息学研究所的Piotr Chrzastowski-Wachtel博士。 一个新的大规模并行架构，被称为P3，导致了一些重要的开放性问题的可行性，适用性和性能的非常大的SIMD系统的识别。 然而，由于商业机器中的强大的趋势最近朝着MIMD机器上的编程的SPMD风格，研究人员正在放松他们以前的SIMD假设，并将他们的知识应用到SPMD系统支持问题。 具体来说，他们的目标是模拟SPMD范例，减少甚至消除屏障同步，以最大限度地减少浪费的处理器空闲。 为此，美国研究人员将与波兰研究人员合作，他们在代数和并发模型方面进行了大量工作。 此外，研究人员希望这次国际交流将为他们在科学数值技术方面的持续研究（MIP-9106949，MIP-9205737）以及非常快速和有效的互连网络的发展提供新的启示。 这项拟议中的信息和计算机科学与工程研究通过使美国和波兰的领先专家能够联合收割机互补人才并在共同感兴趣和能力强的领域汇集研究资源来实现推进科学的计划目标。 ***

9401222 Scherson This U.S.-Poland Joint Collaborative Research grant to study "Efficient System Support for Data-Parallel MIMD" is between Dr. Isaac D. Scherson of the Department of Information and Computer Science, University of California Irvine, and Dr. Piotr Chrzastowski-Wachtel of the Informatics Institute, Warsaw University. A novel massively parallel architecture, dubbed P3, led to the identification of a number of important open problems related to the feasibility, applicability and performance of very large SIMD systems. However, because of the strong recent trend among commercial machines towards the SPMD-style of programming on MIMD machines, the researchers are relaxing their previous SIMD assumptions and applying their knowledge to SPMD system support issues. Specifically, their goal is to model the SPMD paradigm and reduce or even eliminate barrier synchronization to minimize wasteful processor idling. To this end, the American researchers will collaborate with the Polish researchers, who have performed extensive work on algebras and models of concurrency. Additionally, the researchers hope this international exchange will shed new light on their continuing research (MIP-9106949, MIP-9205737) on scientific numerical techniques, and the development of very fast and efficient interconnective networks. This proposed research in information and computer science and engineering fulfills the program objectives of advancing science by enabling leading experts in the U.S. and Poland to combine complementary talents and pool research resources in areas of strong mutual interest and competence. ***
