Ed, I've experimented with various Java parallel processing frameworks, most recently the fork-join framework (JSR166) that will be included in Java 7. The Sphinx-4 automatic speech recognition that I use employs a mulit-threaded phoneme scorer in order achieve better performance. For the most part, the overhead precludes using Java parallelism for small-grained computation tasks in the programs that I write.
However the Microsoft approach is promising according to this article: http://msdn.microsoft.com/msdnmag/issues/07/10/Futures/default.aspx They include a "Parallel for" statement for the .Net platform that I think will be eventually copied by the Java community. It seems to have low overhead, and I suppose that it works by having a hidden thread pool and VM optimization to execute the designated byte-codes in parallel. I have devised a manycore development platform, in advance of the actual availability of these devices, by assembling a small and very cheap Linux cluster.
