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. For a detailed explanation of the design and contents of the ScaLAPACK library, please refer to the ScaLAPACK Users' Guide.
ScaLAPACK is freely available on netlib and can be obtained via the World Wide Web or anonymous ftp.
http://www.netlib.org/scalapack/scalapack.tgzPrebuilt ScaLAPACK libraries are available on netlib for a variety of architectures.
http://www.netlib.org/scalapack/archives/However, if a prebuilt library does not exist for your architecture, you will need to download the distribution tar file and build the library as instructed in this guide.
To install and test ScaLAPACK, the user must have the BLACS, BLAS[9,6,5], and MPI  or PVM  available on his machine.
ScaLAPACK has been tested on MPPs like the IBM SP series, Cray T3E, and SGI Origin 2000/3000, and tested on clusters of PCs and networks of workstations supporting MPI or PVM.8
Section 2 contains step-by-step installation and testing/timing instructions. For users desiring additional information, Section 3 gives details on the testing/timing programs for the ScaLAPACK codes and their input files. Appendices A and B describe the ScaLAPACK driver, computational, and auxiliary routines currently available.
