摘要： 我们描述了在筑波大学计算科学中心开发一个大规模集群系统的计划，该系统峰值速度为14.3 Tflops，作为当前0.6 Tflops CP-PACS计算机的后续系统。该系统由2560个节点组成，这些节点通过一个16×16×10三维超交叉网格网络连接。每个节点配备了一个单核低电压2.8 GHz Xeon处理器和2 GBytes内存（带宽为6.4 GBytes/sec），以及以RAID1模式配置的160 GBytes磁盘。三个方向上的网络链路由双千兆以太网构成，峰值吞吐量为250 MBytes/sec，因此每个节点的总网络带宽为750 MBytes/sec。该系统将在Linux和SCore下运行，并为网络开发了PM驱动程序的扩展版本。该系统将与日立有限公司联合开发。安装计划在日本2006财年的第一季度（2006年4月至6月）进行，预计于2006年7月开始运行。 显示英文摘要

摘要： We describe our plan to develop a large-scale cluster system with a peak speed of 14.3Tflops for lattice QCD at the Center for Computational Sciences, University of Tsukuba, as a successor to the current 0.6Tflops CP-PACS computer. The system consist of 2560 nodes connected by a 16x16x10 three-dimensional hyper crossbar network. Each node has a single low-voltage 2.8GHz Xeon processor and 2GBytes of memory with 6.4GBytes/sec bandwidth, and 160 GBytes of disk in RAID1 mode. The network link in each of the three directions is made of dual Gigabit Ethernet with the peak throughput of 250MByte/sec. Hence each node has an aggregate network bandwidth of 750MByte/sec. The system will run under Linux and SCore, and an extension of the PM driver is developed for the network. The system will be developed jointly with Hitachi Limited. The installation is scheduled in the first quarter of Japanese Fiscal 2006 (April-June 2006) and the start of operation is expected in July 2006.
