                ParPre Parallel Preconditioners Package
                version 2.0.29, released 22 Nov 2000
================================================================

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.

You need compatible versions of Petsc & ParPre; both packages encode
their version number in the name of the tar file.

-- 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, O for optimization>

-- Installation step 3
cd $PARPRE_DIR ; make

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

-- Manual
The most up-to-date version of the manual is in html:
$(PARPRE_DIR)/docs/manualpages/index.html

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

-- KNOWN BUGS
None.
