In my opinion the project would be worthwhile even if it's not in the Top 8. Mentors vote on the accepted projects based both on the priority of the project and the applying student, so it's probably not a bad idea to apply for other projects as well so you don't put all your stakes on just a single horse.
Looking at your current proposal, however, I think that your timeline is, well, impossible. You seem to suggest to build a new allocator and garbage collector from scratch. GHC's allocator is already quite similar to Immix, so you don't really have to re-implement much. The main differences (OTTOH) are the different region sizes, the marking accuracy (Immix marks 128 byte blocks, GHC is word-accurate), and eager compaction. Therefore I'd suggest to move in small steps: Change some parameters (e.g., region size), fix the resulting bugs and benchmark each change. Then, maybe, implement eager compaction on top of the existing system. I believe this will keep you busy enough. If in the end GC is 5% faster that would be a very good outcome! I also don't know how much complexity the parallel GC and other synchronisation stuff will introduce. Maybe Simon (CC'd) can comment on that. / Thomas On 1 April 2010 22:00, Marco Túlio Gontijo e Silva <mar...@debian.org> wrote: > Hi. > > I've written a Google Summer of Code proposal for implementing the Immix > Garbage Collector in GHC[0].
