[gentoo-soc] [GSoC] Weekly Report: June 24 - July 7 - A new framework supports for multiple MPI implementations

[Jian Cao]

Hi,

These two weeks I used some of buffer time, however the basic goal for MPI-Provider is finished:

1. Multiple MPI packages (mpich-3.3, openmpi-4.0.1 are tested) could be installed together on the same system without conflict, with the help of mpi-provider.eclass. There are four main types of paths to maintain - libpath, binpath, incpath and manpath.
2. Refactor modulefiles in order to use specific fixed MPI paths rather than modifying by sed.

There are still several problems to solve to make MPI-Provider work better:

1. Invocate modulefiles properly using eselect; Test MPI loading, unloading and switching.
2. Set system defaults by using symlinks.
3. Port configure options into dedicated functions in eclasses.

Then I will continue to work on the second main part  - MPI-Consumer, the packages depending on specific MPI implementations. In the meantime, I will write documentation for MPI-Provider.

Regards,

Jian
