I have thought about this too, even doing things like modelling climate change through distributed message passing (each process could act like a cube of the earth) but sadly I think the performance is going to be too far from C to be useful. HiPE has seen some very large performance increases in maths performance but still C is going to alway be a substantial amount faster.
