                         Obtaining PARMGRIDGEN 1.0

  ------------------------------------------------------------------------
MGRIDGEN is a serial library written entirely in ANSI C that implements
(serial) algorithms for obtaining a sequence of successive coarse grids that
are well-suited for geometric multigrid methods. The quality of the elements
of the coarse grids is optimized using a multilevel framework. It is
portable on most Unix systems that have an ANSI C compiler. It has been
extensively tested on the following machines :

                         AIX    IRIX  Solaris  SunOS
                       FreeBSD  Linux  Unicos

  ------------------------------------------------------------------------
PARMGRIDGEN is is an MPI-based parallel library that is based on the serial
package MGRIDGEN. PARMGRIDGEN extends the functionality provided by MGRIDGEN
and it is especially suited for large scale numerical simulations. It is
written entirely in ANSI C and MPI and is portable on most parallel
computers that support MPI. It has been extensively tested on the following
machines:

                         SGI Origin    Cray T3E
                          IBM SP 2   Linux Cluster

  ------------------------------------------------------------------------
Both the serial and the parallel library come in one package, namely
PARMGRIDGEN, version 1.0.

To compile PARMGRIDGEN, the serial code of MGRIDGEN must have been installed
on the system first. PARMGRIDGEN-1.0 contains the serial library as well and
it is built automatically. The distribution of PARMGRIDGEN-1.0 consists of a
Unix gziped tar file whose size is approximately 2.6 megabytes. After
downloading PARMGRIDGEN-1.0 you need to uncompress it and untar it. This is
achieved by executing the following commands:

gunzip ParMGridGen-1.0.tar.gz

tar -xvf ParMGridGen-1.0.tar

At this point you should have a directory named ParMGridGen-1.0. This
directory contains MGRIDGEN's and PARMGRIDGEN's source code. To build the
libraries, follow the instructions in the file ParMGridGen-1.0/INSTALL.
Instructions describing how to use the libraries can be found at
ParMGridGen-1.0/Doc/manual-parmgridgen.

A precompiled version of serial MGRIDGEN for Win32 is also available as a zip
archive whose size is 3.7 MB
