Wi4MPI 4.0.0

Features

• This new version includes a brand new generator, which architecture is described in the updated documentation. The source code on GitHub does not includes anymore the generated sources (which was the case for all versions prior to 4.0) but the release does include it. This new generator means more flexibility (it is now possible to target which MPI version and libraries you want to generate the sources for) and more robustness, all functions generated being thoroughly described in associated description files.
• MPI 3.1 is now fully supported

Documentation

• The documentation was re-written to ease the first steps using Wi4MPI for new users
• The developer documentation was fully rewritten to take into account the new generator architecture
