Absolutely agreed. If you're doing large-scale simulation, you need explicit parallel computing. You need C/C++. MPI, ScaLAPACK, the whole shebang. 128 nodes is

Absolutely agreed. If you're doing large-scale simulation, you need explicit parallel computing. You need C/C++. MPI, ScaLAPACK, the whole shebang. 128 nodes is great, but I suspect the simulation will run orders of magnitude faster if written in C/C++.
