Actor Model

I heard of message passing where there is no memory shared.

Is it about Erlang-style Actors?

Scala uses this idea in its Actors framework (thus, in Scala its not a part of the language, just a library) and it looks quite sexy!

In a few words Actors are objects that have no shared data at all, but can use async messages for interaction. Actors can be located on one or different hosts and use interesting error handling policy (when error happened – actor just dies).

You should read more on this in Erlang and Scala docs, its really straightforward and progressive approach!
