The records were set using the ROSS (Rensselaer’s Optimistic Simulation System) simulation package developed by Carothers and his students, and using the Time Warp synchronization algorithm originally developed by Jefferson.

“The significance of this demonstration is that direct simulation of ‘planetary scale’ models is now, in principle at least, within reach,” Barnes said. “‘Planetary scale’ in the context of the joint team’s work means simulations large enough to represent all 7 billion people in the world or the entire Internet’s few billion hosts.”

Maybe they can get SimCity modeled correctly.
