The LRZ praised our work "German National Supercomputer Combined to Run a Single Large Scale Simulation"
"For the first time, researchers simultaneously harnessed the capabilities of the Gauss Centre of Supercomputing’s three high-performance computers, performing a massively high-dimensional calculation related to plasma physics. Parallelization is the defining feature of high-performance computing. Researchers at the University of Stuttgart, however, have taken it to a whole new level. For the first time, they simultaneously integrated all three flagship supercomputers in the Gauss Centre for Supercomputing (GCS), creating a “superfacility” to run a single simulation. Focusing on a high-dimensional problem modeled to the needs of plasma physics, the team used a programming approach called the sparse grid combination technique. This algorithmic method made it possible to distribute and recombine elements of the simulation across the supercomputers JUWELS (Jülich Supercomputing Centre), SuperMUC-NG (Leibniz Supercomputing Centre), and Hawk (High-Performance Computing Center Stuttgart)."Leibniz-Rechenzentrum-der-bayerischen-Akademie-der-Wissenschaften
