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.
