MRI: A PC-based Multithreading Environment for Solving Grand Computational Problems in Science and Engineering

EIA-9977508 Sohn，AndrewMcHugh，James A.新泽西理工学院MRI：一个基于PC的多线程环境，用于解决科学和工程中的大计算问题本提案的目的是探索一种替代昂贵的并行计算的方法，称为集群计算。 其主要思想是开发和建造一种低成本但功能强大的并行计算机，它由通过商品交换机和网卡连接的廉价双处理器个人计算机组成。 为了克服与通用交换机相关联的长通信延迟，建议将多线程和通信协处理器能力联合收割机结合。 在这种方法中，双处理器PC的每个处理器本身具有双重角色，既充当计算处理器又充当通信处理器。使用软件支持的细粒度多线程，每个处理器的二元性允许计算与通信重叠，从而掩盖了长时间的通信。所提出的架构旨在提供性能可扩展性和成本可扩展性。拟议中的研究的主要结果将是一个集群的PC机，可以被用来作为一个强大的并行计算机提供计算科学和工程问题的能力，或作为一个稳定的，可扩展的Web服务器，将适合于电子商务，并在同一时间可以被用来作为一个桌面计算机的日常计算需要。

EIA-9977508Sohn, AndrewMcHugh, James A.New Jersey Institute of TechnologyMRI: A PC-based Multithreading Environment for Solving Grand Computation Problems in Science and EngineeringThe purpose of this proposal is to explore an alternative to the expensive parallel computing, called cluster computing. The main idea is to develop and build a low-cost yet powerful parallel computer that consists of inexpensive dual-processor personal computers connected via commodity switchers and network cards. To overcome the long communication latencies associated with general purpose switches, it is proposed to combine the multithreading and communication co-processor capability. In this approach, each processor of a dual-processor PC has itself a dual role, acting both as a computation processor and a communication processor. Using software-enabled fine-grain multithreading, the duality of each processor allows the overlap of computation with communication, thus masking the long communication. The proposed architecture is designed to provide performance scalability and cost scalability. The principal result of the proposed research will be a cluster of PCs which can be used either as a powerful parallel computer to provide capabilities for computational science and engineering problems, or as a stable, scalable Web server as would be suitable for electronic commerce, and which at the same time can be used as a desktop computer for daily computing needs.
