Re: [rvm-research] running GraphChi with JikesRVM

Possible ... absolutely. Difficult to know how hard it is, though.

AFAICT, the bulk of the work was done in commit ce8f94906f96339b205bccac40c2381f5e44dde6, so try patching with this commit, then find out what breaks and iterate until done.  It doesn't look that big, but it's hard to know what other changes it depends on indirectly.

You may find it easier just to port your own work to 3.1.4, but you won't know until you try.

cheers,
Robin
