VERSION 1.7: August 31, 2001

Abstract

This working note describes how to install and test version 1.7 of ScaLAPACK. This release of ScaLAPACK extends the functionality of the package by providing new routines for the nonsymmetric eigenproblem, divide and conquer symmetric eigenproblem, and improved routines for generalized symmetric eigenproblem and the reduction to tridiagonal form. It also includes PBLAS v2.0. These two-dimensional distributed memory versions of common LAPACK routines rely on calls to the BLAS for local computation, and calls to the PBLAS for global computations. For portability concerns, communication takes place inside the PBLAS through calls to the BLACS. The design of the testing/timing programs for the ScaLAPACK codes is also discussed.
