I definitely think most native languages need some serious work in the parallel department. However, most VMs have had threading done well for a long time. Now we have higher order languages like Scala where multi-threading is even simpler. For example, the number of systems to provide parallel processing on the Java VM number in the thousands.</p> <p>Obviously GCD and parallel C (I like to call them C-Actors) are good things, but let\'s not forget that other technologies out there have been working successfully on a single computer or 10,000 computers for a over a decade. </p> Looks like you are focusing primarily on native code executing on a single machine.

Obviously GCD and parallel C (I like to call them C-Actors) are good things, but let\’s not forget that other technologies out there have been working successfully on a single computer or 10,000 computers for a over a decade.

To me, it\'s a bit hard to grasp. It looks like IPv6 in network world. Powerful things but few people are willing to touch. Majority still work on IPv4. Same as in programming world, majority still work on VB, Java etc. I believe much improvement needed to integrate into those popular language or it just remains as theory. </p> I only have tiny bit knowledge in parallel programming.

It relies on a formal model which ensure a similar behaviour whatever the object is and provides easy to use Java APIs based on the Active Object concept.
