HASE, the Hierarchical computer Architecture design and Simulation Environment, allows for parameterised prototyping of computing systems at multiple abstraction levels encompassing system hardware and application software components. The UKQCD computer simulation research aims to explore the design space and to investigate the performance restricting features of a recent, application-specific supercomputer called QCDOC — Quantum Chromodynamics On-Chip. QCD is a particle physics theory and a 'grand challenge' application. The QCDOC computer employs IBM System-On-Chip technology for a Teraflop-scale supercomputer design. An application-driven simulation approach is introduced for application-specific supercomputer modelling in HASE. Parameterised hardware-software co-simulation models of the QCDOC machine have been created. Advantages of the application-driven co-simulation include a wider design space exploration of hardware components - not restricted by static workload configurations - and simulation metamodelling. Workload scalability and load balancing experiments have been conducted along with performance evaluation of QCDOC's custom-designed features. Moreover, together with HASE features, simulation metamodelling allows efficient generation of alternate simulation models with maximum component reuse and minimum design overhead. Experiments with HASE QCDOC and its successor Bluegene/L simulation models confirm that QCDOC on-chip memory configurations are optimised for QCD code.
