Xavier, Thanks for the comments. I thought that float ref's were unboxed by default! In fact, I find that breaking out the code into a stand- alone example which loops through matrix multiplies only indeed does not have any calls to caml_modify; everything is unboxed and stored on the

if it would be better to implement ref on top of a single-cell array, since then everyone would get the float unboxing whenever applicable. I imagine there is some runtime overhead to this, though. y On Aug 28, 2009, at 4:32 PM, Will M Farr f...@mit.edu wrote: Hello all, I'm running OCaml

Atmam, I've had some luck using OCaml with MPI (using the OCamlMPI library at http://caml.inria.fr/cgi-bin/hump.en.cgi?contrib=401 ). That may not satisfy your needs as far as multi-core goes, but perhaps it will. I can't speak to the speed of the interface (my operations were compute-bound on
