Performance of the BLAS-1 and other mathematical kernels on the SGI/Cray Origin 2000 processor
The purpose of this paper is to explore issues related to the computation and communication performance of the Basic Linear Algebra Subroutines (BLAS-1) and related kernels on the SGI/Cray Origin 2000 parallel computer. Experiments are performed both on vendor-supplied mathematical library routines as well as hand-coded loops and array syntax. The goal of this study is to get a better understanding of performance issues pertaining to the Origin 2000 architecture.
