====== Objective Caml for Multicore Architectures ======

This project aims at allowing Objective Caml to take advantage of multicore architectures, notably those now commonly used in laptops and desktop PC.


===== News =====
  * **2010 spring-summer (current work, in progress)** : (ocaml-3.12-svn) "from scratch", making the runtime library fully reentrant, first without threads preoccupation
  * **early 2010** : (ocaml-3.11.1) adaptation to work on x84-32 and x84-64, with Linux and Mac OS X. Fairly unstable.
  * **late 2009** : (ocaml-3.11.1) adaptation of the modified runtime library for ocaml-3.11.1
  * **mid/late 2009** : (ocaml-3.10.2) several working implementations for X86-64 (with or without partial collections)
  * **late 2008** : (ocaml-3.10.2) first unsafe implementation for X86-64 architecture, running Linux

===== History =====

It started in 2008 as an [[http://ocamlsummerproject.com/|OCaml Summer Project]] 2008 funded by [[http://www.janestreet.com/|Jane Street Capital]]. It has continued since then.


===== Distribution =====
**Warning : For testing purpose only. It should not be used for production.**

== without partial collection ==
[[http://www.algo-prog.info/ocmc/distribution/oc4mc-smartpumpkin.tar.gz |oc4mc-smartpumpkin.tar.gz]]
  * (feature) growing capable shared heap : if a huge allocation is needed, the heap grows such that it becomes possible (i.e. with system malloc limitation only) instead of going into an endless broken loop
  * (feature) limited shrinking : the shared heap can never become smaller than its initial size

== with partial collection ==
[[http://www.algo-prog.info/ocmc/distribution/oc4mc-smartpumpkin-with-partial-collection.tar.gz |oc4mc-smartpumpkin-with-partial-collection.tar.gz]]
  * (feature) partial collection enabled : partial collection when the shared heap has more free space than required for flushing full pages
