The team said that the upcoming 3D simulation they plan to run will not only require GPUs—it will eat up nearly all of the team’s INCITE time for the entire year.

“We need to get every ounce of performance we can,” Zingale said. “Luckily, we have learned from these 2D simulations what we need to do for our 3D simulation, so we are prepared for our next big endeavor.”
