Normal simulations aren't using any linear algebra stuff at all. BLAS
& LAPACK are only useful when you do matrix stuff, for instance
normal mode analysis.

GPUs aren't useful for general simulations yet, since
neighborsearching isn't working. We have good hopes for the future
though, and if/when it's working we'll of course include it.
