We have enjoyed our 4x quad system that we mainly use for sparse matrix circuit solvers, though the current algorithms used don't seem to scale well. Instead of trying to run a single simulation on as many cores as possible, we do many different simulations at once. This trend might move us towards more quadratic programming or differential evolution where you are wanting to search a n-dimensional parameter space for optimization.
