[erlang-questions] Dryad or MapReduce in Erlang?

[Raoul Duke]

(haven't managed to find this talked about yet, sorry if this is old
material.) One interesting thing about Map Reduce and Dryad is that, I
think, they can dynamically choose how many machines and processes are
involved in servicing the high-level plan. Are there things in the
Erlang world with similar abilities of abstraction? So far I've been
under the impression that most Erlang applications know ahead of time
the intended distribution of things.

thanks for any edification,
