We are releasing version 1.0 of MP_SOLVE under the GNU public
license.  MP_SOLVE is used to solve sparse, irregular systems of
equations with multiple right-hand sides on distributed memory,
multiprocessor computers having the MPI communications library.  The
software has been tested on the Convex SPP-2000, an Intel-based
beowulf system with ethernet networking and an Intel-based beowulf
system with myrinet networking.  The Chaco graph partitioning software
from Sandia National Laboratories is used to obtain a
nested-dissection partition of the system of equations on a serial
computer in a pre-processing step.  MP_SOLVE is available in three
versions:

1.  real, double-precision coefficient matrix, real, double-precision
right-hand sides,

2.  real, double-precision coefficient matrix, complex, double-precision
right-hand sides and,

3.  complex, double-precision coefficient matrix, complex, double-precision
right-hand sides.

The software can be downloaded from the web page:

The BLAS libraries are needed for MP_SOLVE.  Greg Henry's optimized
Pentium Pro BLAS are highly recommended when running MP_SOLVE on an
Intel system:

A paper describing MP_SOLVE including benchmarks will be available at
the above web page in the near future.  Your feedback is greatly
appreciated.
