Hypre is a massively parallelizable linear solver library written and designed for use in C++. It provides many nice features and objects beyond simple "matrix" or "vector" objects - these include grids, meshes, and stencils. It was developed at Lawrence Livermore National Lab.

Installation

Installing Hypre can be tricky. The documentation will give much more in-depth details than this page. Links to the documentation are available at https://computation.llnl.gov/casc/hypre/software.html .

Dependencies

Hypre will require an installation of MPI on your machine. I use LAM MPI, but you can also use OpenMPI.

Configuration

Download the hypre tarball and decompress it. Put your configure wrapper into the src/ directory of the decompressed Hypre tarball.

Mac OS X

This configure line has been used to build Hypre 2.0.0, which is the latest stable release. It has not been tested on beta releases.

#!/bin/sh
#
# run configure
# make
# make install

./configure \
    --with-MPI-include=/path/to/lam-mpi/include \
    --with-MPI-lib-dirs=/path/to/lam-mpi/lib \
    --with-MPI-libs="mpi lam pmpi util" \
    --prefix=/path/to/hypre \
    \
    F77=/usr/local/bin/gfortran \
    \
    CFLAGS=-DMPIPP_H \
    CXXFLAGS=-DMPIPP_H

The -DMPIPP_H compiler flags are only required for LAM MPI and OpenMPI; they are not needed if you use any other MPI install (e.g. MPICH).
