OcamlMPI hacking

Posted on 2011-01-13 04:32

My first foray into meddling with C interfaces, great for learning and helping me improve the performance of an MPI code I'm working on. I'm using a lot of hypercube/mesh/etc. communication patterns in my code so I have a good deal of pt2pt exchanges. It turns out that ocamlmpi has a quite small overhead but the lack of proper non-blocking communications almost halves the performance of the communication algorithms (such as the hypercube mnac). I've already written a patch and tested it. I'm glad the project admins granted access, I should be committing the first bits tomorrow. Cheers, Eray
