Status of the Cp-pacs Project 1. the Cp-pacs Projectt1] 2. Cp-pacs Computer 2.1. Design Parameters

The CP-PACS Project, which started in April 1992, is a ve-year plan to develop a massively parallel computer for carrying out research in computational physics with primary emphasis on lattice QCD. This article describes the architectural design of the CP-PACS computer, the entire computing system including the front end and mass storage, and results of benchmarks for the expected performance f...

Status of the Cp-pacs Project Y. Iwasaki a for the Cp-pacs Collaboration

The CP-PACS computer with a peak speed of 300 GGops was completed in March 1996 and has started to operate. We describe the nal speciication and the hardware implementation of the CP-PACS computer, and its performance for QCD codes. A plan of the grade-up of the computer scheduled for fall of 1996 is also given. 1. CP-PACS project The CP-PACS projectt1] is a ve-year project which formally start...

CP - PACS results for quenched QCD spectrum with the Wilson action ∗ CP - PACS

We present progress report of a CP-PACS calculation of quenched QCD spectrum with the Wilson quark action. Light hadron masses and meson decay constants are obtained at β =5.9, 6.1, and 6.25 on lattices with a physical extent of 3 fm, and for the range of quark mass corresponding to mπ/mρ ≈ 0.75 − 0.4. Nucleon mass at each β appears to be a convex function of quark mass, and consequently the va...
