Hyperthreading was never remarkable about performance or whatever and is probably not pure SMP (emulated SMP maybe?). > So, what're the developments regarding SMP multithreading OCaml? > There are various development regarding this subject (most recent first): - Plasma (MapReduce in OCaml) http://plasma.camlcity.org/plasma/index.html - OC4MC (OCaml for MultiCore) http://www.algo-prog.info/ocmc/web/ - ocamlp3l http://camlp3l.inria.fr/eng.htm - jocaml http://jocaml.inria.fr/ - ocamlmpi http://forge.ocamlcore.org/projects/ocamlmpi/ All these projects try to tackle the challenge of SMP from different point of view. Maybe you'll find what your answer in one of them. Regards, Sylvain Le Gall _______________________________________________ Caml-list mailing list.
