Germany's JUPITER becomes fourth fastest supercomputer in the world

Germany’s JUPITER supercomputer, located at the Jülich Supercomputing Centre (JSC), has become the fourth fastest supercomputer globally and the fastest in Europe. This achievement was supported by a collaboration with Georgia Tech, where Assistant Professor Spencer Bryngelson accessed JUPITER through the JUPITER Research and Early Access Program (JUREAP). Bryngelson’s Multi-Component Flow Code (MFC) was tested on JUPITER to study the behavior of droplets subjected to high-velocity shockwaves, a complex fluid dynamics problem with significant engineering implications, especially for supersonic and hypersonic aerospace applications. The simulations revealed how droplets deform and break apart under shockwaves, providing valuable insights that help reduce risks and costs associated with physical testing. The MFC project, part of the broader Exascale Multiphysics Flows (ExaMFlow) collaboration between Georgia Tech and JSC, demonstrated strong performance on JUPITER’s key components—the JUWELS
