Alya code scaled to 100,000 cores on Blue Waters supercomputer

The Barcelona Supercomputing Center (BSC) and the Private Sector Program at the National Center for Supercomputing Applications (NCSA) have collaborated to scale BSC’s Alya multi-physics code to a previously unprecedented 100,000 cores of NCSA’s Blue Waters supercomputer, simulating complex engineering problems such as airflow in the human body, contraction of the heart, and combustion in a kiln furnace.

MechSE adjunct professor Seid Koric played a key role in this international collaboration, which he said may open a new chapter in large-scale multiphysics modeling in engineering globally.

"These unprecedented results contradict the common belief that engineering simulation codes do not scale efficiently in large supercomputers, opening a new wide horizon of potential applications in the industrial realm," Koric said.
