Terascale Computing System

匹兹堡超级计算机中心（PSC）是匹兹堡大学和卡内基梅隆大学通过MPC公司与西屋电气公司合作共同支持的企业，将为美国所有科学和工程学科的研究人员提供6个峰值万亿次运算系统。 该系统将由Compaq提供，基于686个基于4处理器Alpha 21264的SMP节点和Quadrics ELAN 4互连的集群;它将具有2.7 TB的内存，25 TB的本地磁盘和160 TB的全局磁盘。该系统将分两个阶段部署。最初的系统将包括ES 40系统，16个节点将于2000年9月抵达。10月，该系统将升级到64个节点，并以友好用户模式提供。这将为为数不多的用户提供一个相对稳定的生产环境奠定基础，并将继续使用，直到2001年10月最后系统完成为止。最终的TCS系统将于5月开始交付给PSC，而256个节点的测试系统将于2000年12月在Compaq提供。一个256个节点的系统将于2001年6月在PSC安装，然后在2001年9月稳步增加到大约618个节点。2001年10月完成初始系统的转换，最终完成686节点系统。拨款将由现有的公民信息总署国家资源分配委员会管理。

The Pittburgh Supercomputer Center (PSC), a jointly supported venture of The University of Pittsburgh and Carnegie Mellon University acting through the MPC Corporation, in collaboration with Westinghouse Electric Corporation, will put in place a 6 peak teraflop computing system for use by US researchers in all science and engineering disciplines. The system will be provided by Compaq, based on a cluster of 686 4-processor Alpha 21264 based SMP nodes and Quadrics ELAN4 interconnects; it will have 2.7 terabytes of memory, 25 terabytes of local disk and 160 terabytes of global disk. The system will be deployed in two stages. The initial system will consist of ES40 systems with 16 nodes arriving in September 2000. In October the system will be upgraded to 64 nodes and be available in friendly user mode. This would form the basis of a relatively stable production environment for a modest number of users and will remain in service until the final system is completed in October 2001. Delivery of the final TCS system to PSC will begin in May although a 256-node test system will be available in December 2000 at Compaq. A 256-node system will be installed at PSC in June 2001 followed by a steady increase in size to about 618 nodes in September 2001. The conversion of the initial system to complete the final 686-node system in October 2001. Allocations will be managed by the existing PACI National Resource Allocation Committee (NRAC).
