Roland Kaufmann f786b832c0 Enable MPI if path is given 
Assume that ./configure --with-mpi= also implies --enable-mpi; if you
absolutely want to specify path without enabling (?!) then you can do
--with-mpi=... --disable-mpi (in that order).

This patch look for anything after the equal sign of the --with
parameter and only set the variable _MPI_PREFIX_PATH if that is given;
it always toggle USE_MPI.

Open Porous Media Automatic Differentiation Library

CONTENT

opm-autodiff contains a small library for automatic differentiation built on the Eigen linear algebra package. It also contains some experimental solver and simulator prototypes demonstrating how it can be used. The most important parts are:

  • AutoDiffBlock.hpp (class for AD on vectorized data with sparse jacobians)
  • AutoDiffHelpers.hpp (various utilities to simplify writing solvers)
  • sim_fibo_ad.cpp (prototype fully implicit black-oil simulator)

LICENSE

The library is distributed under the GNU General Public License, version 3 or later (GPLv3+).

PLATFORMS

The opm-autodiff module is designed to run on Linux platforms. It is also regularly run on Mac OS X. No efforts have been made to ensure that the code will compile and run on windows platforms.

REQUIREMENTS

opm-autodiff requires opm-core, and all its requirements (see opm-core/README). In addition, opm-autodiff requires Eigen, version 3.1 (has not been tested with later versions).

DOWNLOADING

For a read-only download: git clone git://github.com/OPM/opm-autodiff.git

If you want to contribute, fork OPM/opm-autodiff on github.

BUILDING

See build instructions in opm-core/README, or at http://opm-project.org/download.php.

DOCUMENTATION

Efforts have been made to document the code with Doxygen. In order to build the documentation, enter the command

make doc

in the topmost directory. The class AutoDiffBlock is the most important and most well-documented.

REPORTING ISSUES

Issues can be reported in the Git issue tracker online at:

https://github.com/OPM/opm-autodiff/issues

To help diagnose build errors, please provide a link to a build log together with the issue description.

You can capture such a log from the build using the `script' utility, e.g.:

LOGFILE=$(date +%Y%m%d-%H%M-)build.log ;
cmake -E cmake_echo_color --cyan --bold "Log file: $LOGFILE" ;
script -q $LOGFILE -c 'cmake ../opm-core -DCMAKE_BUILD_TYPE=Debug' &&
script -q $LOGFILE -a -c 'ionice nice make -j 4 -l 3' ||
cat CMakeCache.txt CMakeFiles/CMake*.log >> $LOGFILE

The resulting file can be uploaded to for instance gist.github.com.
