Check this great article from Gul Agha, Communication of the ACM .

The actor model is more and more supported by languages such as Erlang , Scala or environments such Ptolemy from UC Berkeley (a project I contributed).
The challenge will be to provide a simple solution, yet powerful, to help developers with no parallel programming skill. With its graphical approach and its abstract models of computation, Ptolemy seems an interesting solution ;-)
