Rich has done some work on using the JDK7 ForkJoin Library to parallelise map and reduce over vectors, since they are already internally structured as trees. It hasn't been touched in a while, but as far as I know the code lives in the 'par' branch of the clojure repository, and works with JDK6 if you install an additional jar. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
