Getting Started

To download the developer version you need to use GIT. The latest development version of SeLaLib is tracked in the ‘master’ branch.

Documentation for Git is available here.

First time set up

Set up your developer info:

git config --global "Your NAME"
git config --global "you@somewhere"
git config --global core.editor emacs (or other)
git config --global merge.tool opendiff (or other)

Check configuration with:

git config --list

For help:

git help <command-you-want-help-about>

Get the source code

Developer GIT Access via SSH

Edit keys on your INRIA gforge account and follow instructions. Only project developers can access the GIT tree via this method. Substitute with the proper values:

git clone git+ssh://
cd selalib/

Display all branches with:

git branch -a

Create the local branch and merge the remote branch:

git checkout master

More information available on document An overview of GIT A short tutorial for SELALIB developers by Edwin Chacon-Golcher.

Build the devel branch

Create a new directory, build the libraries within

mkdir build
cd build
cmake ../
make Experimental

CMake is a system for managing the build process of software. It writes in a CMakeCache.txt file all parameters that it has detected on your system. CMake can to not detect libraries installed for several reasons. So we need to edit the CMake cache. If you have already performed cmake you can run

make edit_cache

otherwise run

ccmake ../

As you can see there is now a user interface that allows to edit parameters. Press [c] to configure up to the configuration is valid and that the line “Press [g] to generate and exit” appear.

Details about principle parameters






When set to ON disable all reference to mpi and run SeLaLib in sequential.



By default SLLFFT. SeLaLib provide a fast fourier transform module around 3 libraries, fftpack, fftw and his own implementation.


/usr/local /opt/local /usr …

For output we need to link the lib with HDF5 and FFTW3. Parallel is better but serial works. With this you can use your own implementation
