Abstract

CP-PACS (Computational Physics by Parallel Array Computer System) is a massively parallel processor with 2048 processing units, built at the Center for Computational Physics, University of Tsukuba, Japan. The node processor of CP-PACS is a RISC microprocessor enhanced by pseudo vector processing, which can realize high performance vector processing. The interconnection network is the 3 dimensional Hyper-Crossbar Network, which has high flexibility and embeddability for various network topologies and communication patterns. The theoretical peak performance of the whole system is 614.4 GFLOPS. We present an overview of the CP-PACS architecture and several special architectural characteristics of it. A performance evaluation on the parallel LINPACK benchmark is also shown
