The 23rd call for GCS Large-Scale Projects is open for applications from German universities and publicly funded German research institutions – and it comes with revised criteria regarding the definition of “large-scale” projects. As of immediately, simulation projects fall into the category “large-scale” only if they require at least 100 million core-hours of computing time on Hawk of HLRS, or 15 Mcore-h on JUWELS of JSC, or 45 Mcore-h on SuperMUC-NG of LRZ over a period of 12 months. These values correspond to 2% of the systems’ annual production in terms of estimated availability. Scientists can apply for computing time on these three GCS HPC systems until February 10, 2020, 17:00hrs.
