There used to be a beautiful processor architecture called Transputer
and the language called Occam to program it. Making things going
parallel was even more easier and natural than in Erlang.
And there were many papers published, that going from extreme parallel
systems to more serialised one was the way optimise the performance.
Extreme parallel meaning systems, where you have decades more processes
than real executing hardware. It all depends on the process switching
time and communication overhead.
