Concurrency paradigms

[bearophile]

I don't like slideshare site, but this block of slides are intererting, "State: You're Doing It Wrong - Alternative Concurrency Paradigms For The JVM":
http://www.slideshare.net/jboner/state-youre-doing-it-wrong-javaone-2009

It shows that different problems may enjoy different kinds of concurrency paradigms. It shows me that actors (with a nice syntax) have to be in std lib of D2. I guess D2 will have the capability to implement software transactional memory.

Other concurrency paradigms are the one shown by Cilk, and the data parallelism (used for numeric processing, in modern Fortran, parallel Pascal, Fortress, and probably better in Chapel).

Such stuff (all three forms of concurrency) is so basic and useful that it has to be in the std lib (and partially implemented in the language itself where necessary).

I'd really like to see D2 language become used as a replacement for parallel Fortran, with efficient & easy to use features to perform parallel numeric processing (see Chapel, on this).
