New GCS Large-Scale Projects in May 2020

Twice a year, the Gauss Centre for Supercomputing (GCS) issues a call for large-scale projects on its petascale supercomputers – Hawk (HLRS), JUWELS (JSC), and SuperMUC-NG (LRZ). Until now, projects were classified as “large-scale” if they required at least a combined 35 million core-hours (Mcore-h) per year on the GCS member centres’ systems. These specifications for large-scale projects have been changed. From now on, projects fall into the category “large-scale” only if they require at least 100 Mcore-h on Hawk, 15 Mcore-h on JUWELS, or 45 Mcore-h on SuperMUC-NG. These values correspond to 2 % of the systems’ annual production in terms of estimated availability.

The GCS Peer Review Board decided to award the status of a large-scale project to 20 projects from various scientific fields. Five projects were granted 1,590 Mcore-h on Hawk, five projects were granted 105 Mcore-h on JUWELS, and ten projects were granted 640 Mcore-h on SuperMUC-NG. In total, the GCS awarded about 2.3 billion compute core hours to large-scale projects. For more details of these projects, visit
