You can choose between an implementation based on MPI or PVM. This package uses MPI. There are packages for the shared libraries, for the static libraries and the development files, and for test programs (this one).
Most users do not need to install this package directly because it contains test programs for the BLACS libraries. You only need these if you experience problems with ScaLAPACK. The BLACS libraries are used as a high level communications library for ScaLAPACK. ScaLAPACK is a parallel version of LAPACK and is used on Beowulf type clusters.
You need write access to be able to run the tester applications. Suggestion: $ cp /usr/lib/blacs/* /tmp $ cd /tmp $ mpirun.mpich -np 4 cblacs_test_shared-mpich etc.
