I think you should probably design a processing model first and then when you
know how it should operate go looking for the best platform. Erlang probably
won't be it, more likely MPI or its ilk, simply because Erlang isn't designed
to move large amounts of data (you're probably talking GB); but rather to be
massively concurrent on small narrow tasks.

Erlang can interact with programs in the host through "ports" which can be eg.
IPC pipes or specially written shared libraries loaded by erlang.
