New GCS Large-Scale Projects Started in May 2022

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). Projects are classified as large-scale if they require at least 2 % of the systems’ annual production in terms of estimated availability.

While computing time quantities were previously specified in core hours, the modularity of JUWELS requires the introduction of a new computing time unit. JSC currently specifies computing time based on the peak floating point operations per year (FLOP/a) of the computing devices (CPU or GPU) available to approved projects. Computing time on Hawk and SuperMUC-NG continues to be specified in core hours. Therefore, projects are only categorized as large-scale if they require at least 100 Mcore-h on Hawk, or 45 x 1021 FLOP/a on JUWELS, or 45 Mcore-h on SuperMUC-NG.

At the end of April, the GCS Peer Review Board decided to award the status of large-scale project to 17 projects from various scientific fields. In total, two projects were granted 1057 Mcore-h on Hawk, five projects were granted 295 x 1021 FLOP/a on JUWELS, and ten projects were granted 585 Mcore-h on SuperMUC-NG.
