Re: [Caml-list] Re: Concurrent and Distributed Programming in Ocaml

[David Teller <David.Teller@ens-lyon.org>]

While this module is absolutely great, it suffers from OCaml's
limitation that multi-threaded code runs only one one processor, even if
several are available.

For concurrency, I would suggest taking a look at Acute, but that's
quite low-level, when compared to JoCaml. Basically, the communication
primitives are similar to a somewhat lower-level version of the Event
module. I don't know whether there is a native code compiler, though.

Cheers,
 David
