This article outlines the content and performance of some of the ScaLAPACK software. ScaLAPACK is a collection of mathematical software for linear algebra computations on distributed-memory computers. The importance of developing standards for computational and message-passing interfaces is discussed. We present the different components and building blocks of ScaLAPACK and provide initial performance results for selected PBLAS routines and a subset of ScaLAPACK driver routines.
