Abstract: The study of Quantum Chromodynamics (QCD), a branch of Particle Physics, is considered a Grand Challenge application; a Grand Challenge is a fundamental problem in science and engineering, with broad applications, whose solution would be enabled by the application of high performance computing resources. Commercial and custom-built high-performance parallel computers have been used around the world for QCD research for the past 20-30 years. Custom-built massively-parallel QCD machines have a better cost/performance ratio compared with commercial high performance computers and are therefore more attractive to academic researchers. The success of special-purpose parallel computers has paved the way for research and development in many computer science disciplines including parallel architectures, processor design and high-performance compiler design.
This article outlines design steps of a recent state-of-the-art QCD computer called QCDOC (QCD On-a-Chip) and presents an overview of its simulation model in HASE. The primary aim of this research is to explore the hardware and software factors that can influence the performance of the QCD computer.
