Basic Linear Algebra Comm. Subprograms - Shared libs. for MPI

The BLACS project is an ongoing investigation whose purpose is to create a linear algebra oriented message passing interface that may be implemented efficiently and uniformly across a large range of distributed memory platforms.

You can choose between an implementation based on MPI or PVM. This package uses MPI. There are packages for the shared libraries (this one), for the static libraries and the development files, and for test programs.

Most users do not need to install this package directly because it is used as a high level driver for the communication in the ScaLAPACK packages. Therefore, it is installed when installing ScaLAPACK. ScaLAPACK is a parallel version of LAPACK and is used on Beowulf type clusters.

Package version:1.1-28.2+b1


All users of the BLACS should read "A User's Guide to the BLACS v1.1".
Users may also be interested in the quick reference guides for the C and
Fortran77 interfaces to the BLACS.

Before you can compile anything, you must first edit and correct the file
BLACS/  Sample's can be found in the BLACS/BMAKES
directories.  See the paper "Installing and Testing the BLACS" for details.
