MLton and SML/NJ are both multicore incapable. The PolyML implementation of SML is multicore friendly but last time I looked (many years ago) it was 100x slower than OCaml for floating point. As long as you're looking at OCaml's close relatives with multicore support, F# is your only viable option. Soon, HLVM will provide a cross-platform open source solution. If you look further you will also find Scala and Clojure. > Note that if you're not using a lot of threads, you can use Unix.fork to > do true multithreaded programming ocaml. We've discussed the problems with that before. Writing a parallel generic quicksort seems to be a good test of a decent multicore capable language implementation. Currently, F# is a *long* way ahead of everything open source. -- Dr Jon Harrop, Flying Frog Consultancy Ltd. http://www.ffconsultancy.com/?e _______________________________________________ Caml-list mailing list.
