Abstract

This paper describes the performance evaluation and modeling of the CM-5 multiprocessor. We provide a number of benchmarks for its communication and computation performance. We have also benchmarked many operations, like scans and global reduction, that can be performed using special hardware available on the CM-5. Most of these operations are are modeled using regression on appropriate parameters. These models are used to predict the performance of Gaussian Elimination on the CM-5. Comparative timing on the Intel Touchstone Delta machine are also provided. We also describe how to efficiently embed a mesh and a hypercube on a CM-5 architecture and provide timings for some mesh and hypercube communication primitives on the CM-5.
