The slowness of Erlang was a conscious decision. You're supposed to offload all the computationally intensive things to native code. That may not be ideal for your use case and a PITA, but it's how the language and runtime was designed. I would guess Erlang would do (if it isn't already doing) well in HPC as the thing that coordinates all the Fortran code.
