Do Scala and Erlang use green threads?
- by CHAPa
I've been reading a lot about how Scala and Erlang does lightweight threads and their concurrency model (actors).
However, I have my doubts.
Do Scala and Erlang use an approach similar to the old thread model used by Java (green threads) ?
For example, suppose that there is a machine with 2 cores, so the Scala/Erlang environment will fork one thread per processor? The other threads will be scheduled by user-space (Scala VM / Erlang VM ) environment. Is this correct?
Under the hood, how does this really work?
