Abstract

Basic Linear Algebra Subroutines (BLAS-3) [1] are building blocks to solve a lot of numerical problems (Cholesky factorization, Gram-Schmidt ortonormalization, LU decomposition,…). Their efficient implementation on a given parallel machine is a key issue for the maximal exploitation of the system’s computational power. In this work we refer to a massively parallel processing SIMD machine (the APE100/Quadrics
