Abstract

The results of various implementations of Gaussian elimination on full matrices on a single processor Cray Y-MP are presented and discussed. It is shown that when the manufacturer supplied BLAS kernels are used, the difference between thebest versions of level 2 BLAS and level 3 BLAS (blocked) implementations is almost negligible. It is suggested that to improve the performance of blocked Gaussian elimination it is possible to utilize Strassen's matrix multiplication algorithm.
