I've already mentioned that I'd be interested in picking this up as a
potential project. However, the entire implementation may not be
possible in a single summer. It is rather complex, and while a naive
implementation may be possible to write, we would want something more
efficient. I'm hoping for some pointers on where I should start
looking for a better understanding of the codebase.
It would definitely help to have a co-mentor from the MPI (e.g. one of
the authors of the paper). The SMP scheduler is a rather self-contained
part of the operating system. I will probably add some internal
documentation in the next months. It would be really nice if we could
run the tests of the original paper.
However, apart from this, even Eliminating the Giant Lock and
Implementing OMIP could potentially be GSoC projects. These may not be
extremely large changes, and you could probably finish them in a
couple of weeks, but they would take someone new much longer.
Reasoning about the new code will not be trivial.
Implementing OMIP is very complex. The Giant lock elimination is complex
in some areas (thread restart/delete) and quite boring in most areas. I
guess some trouble will arise in case I accidentally change some code
patterns.
