How many supercomputers does it take to simulate plasma turbulence? Quite a few, it turns out. Researchers from the University of Wisconsin-Madison (UW) utilized a number of ACCESS resources, including Stampede2 from the Texas Advanced Computing Center (TACC), Expanse from the San Diego Computing Center (SDSC) and Bridges-2 from the Pittsburgh Supercomputing Center (PSC). But it was Anvil, from Purdue’s Rosen Center for Advanced Computing (RCAC) that did some of the heaviest lifting. Fully half of Anvil’s resources were used in the single simulation – a whopping 512 nodes used at once.
