                version 2.0.21, revision 1, released April 1998
================================================================

This package contains a number of parallel preconditioners
for iterative methods such as the method of conjugate gradients.

-- Installation step 1
For installation, you need to have the MPI library
and the Petsc libraries installed.

You can find Petsc at
http://www.mcs.anl.gov/petsc/petsc.html
or directly by anonymous ftp from info.mcs.anl.gov in pub/petsc 
as petsc.tar.Z orpetsc.tar.gz.

This is version 2.0.21 of the ParPre library; correspondingly
you need Petsc 2.0.21 or later.

-- Installation step 2
The following environment variables need to be set:

PETSC_DIR <location of the Petsc library>
PETSC_ARCH <machine type; check $PETSC_DIR/bmake for possibilities>
PARPRE_DIR <location of the ParPre library>
BOPT <optimisation type; eg, g for debug>

-- Installation step 3
cd $PARPRE_DIR ; make all

This may give a few compiler warnings.
If any real errors show up, please contact eijkhout@math.ucla.edu

-- Manual
Print out $PARPRE_DIR/man.ps, or read online
http://www.cs.utk.edu/~eijkhout/reports/parpre_manual/manual.html

-- Example programs
The directory $PARPRE_DIR/Examples gives you a makefile, a Readme,
and some example codes in C.

-- KNOWN BUGS
None.
