Comparing the performance of the DASH and Cedar multiprocessors for scientific applications

Research output: Contribution to journal › Conference article › peer-review

Abstract

Scalable shared-memory multiprocessors are attractive because they achieve large-scale parallel processing without surrendering much programmability. Several such machines have been built or are currently being built, for instance RP3, Cedar, KSR1, DASH, DDM1, Alewife, Cray T3D, or the Tera computer system. While all these machines support the shared-memory paradigm, they differ significantly. For example, some of them use hardware to support cache coherence, while others rely on the compiler or the programmer to do so. Furthermore, a subset of the machines are hierarchical, and some have the processors grouped in clusters. In addition to these and other hardware issues, machines also differ in software issues. For instance, the most natural model of parallelism supported by compilers and the operating system can be task- or loop-based.
