Parallel programming in Java

Hi All, I am in need of a parallel programming framework or tutorial. Can anyone of you please give me a direction in this regard. I am aware of a Fork-Join approach however it is scheduled to be release with JDK7...

Are you just trying to take advantage of multiple cores on one physical box, or are you looking to spread work out over a cluster?

If it's the former, JVM threads should be able to take advantage of multiple cores, IIRC. Just read Doug Lea's book on Java concurrency:

If you want to go over a cluster, there are a few options. If your problem can be done in map/reduce fashion, there is Hadoop: http://hadoop.apache.org or if you want a traditional RCP styled approach (eg, MPI), there are Java bindings for MPI: http://aspen.ucs.indiana.edu/pss/HPJava/mpiJava.html

In either case, Doug's homepage is a great resource: http://gee.oswego.edu/~dl/index.html

and the HPJava page might be of interest as well:
