Abstract

Analysis of future parallel computers requires rapidly simulating target designs running realistic workloads. Two techniques have accelerated such simulations: direct execution and using a parallel host. Historically, these techniques have lacked portability. The authors identify four key operations necessary to make these simulations portable. This lets them run the Wisconsin Wind Tunnel II readily on a wide range of Sparc platforms from a workstation cluster to a symmetric multiprocessor. WWT II has good performance and scalability, as shown on a range of benchmarks. It achieves speedups between 8.6 and 13.6 on a 16-host-processor SMP. Finally, the authors show that parallel simulation with WWT II is cost effective.
