for finding all eigenvalues and eigenvectors of real symmetric
diagonalizable matrices in parallel

abstract

These routines find all the eigenvalues and eigenvectors of
real symmetric diagonalizable matrices and can easily be adapted to only
resolve a certain part of the spectrum.All routines use MPI for
their message passing. As a result, they should run on any machine
which supports MPI. The code has been tested extensively on a wide
variety of parallel architectures and test cases. There is also a
User's Guide which provides directions on installing the package and
explains the user interface.

comments

This package is part of the PRISM (Parallel Research on Invariant
Subspace Methods) project. There are a large number of technical
reports, conference papers, and working notes available via anonymous
ftp from ftp.super.org in pub/prism or via a WWW browser from
ftp://ftp.super.org/pub/prism. There is a README file which lists all
of the reports/code contained in that directory. The code and User's
Guide are located in file prism_syisda.tar.Z.
