Erlang, scala/akka, haskell/ghc and clojure all have compelling takes on concurrency (C#/F# too). In erlang's case, it's the lightest of lightweight processes.

Erlang, scala/akka, haskell/ghc and clojure all have compelling takes on concurrency (C#/F# too). In erlang's case, it's the lightest of lightweight processes. I've seen blogs describing erlang apps spinning up millions of processes. Those are the kinds of numbers that akka and ghc are shooting for (I don't have an akka reference: http://www.serpentine.com/blog/2009/12/17/making-ghcs-io-manager-more-scalable/ http://www.serpentine.com/blog/2009/12/17/making-ghcs-io-man... http://www.slideshare.net/jboner/akka-scala-days-2010 http://www.slideshare.net/jboner/akka-scala-days-2010
