New GCS Large-Scale Projects in November 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). Projects are classified as “large-scale” if they require at least 2 % of the systems’ annual production in terms of estimated availability.

Currently, the JUWELS Booster module is being installed and made available to applicants for the first time in this call. Whilst computing time quantities were previously specified in core hours, the modularity of JUWELS requires the introduction of the new computing time unit EFLOP, which reflects the amount of floating-point operations per year available to approved projects. The computing time on Hawk and SuperMUC-NG continues to be given in core hours. From now on, these projects will only fall into the “large-scale” category if they require at least 100 Mcore-h on Hawk, 45,000 EFLOP on JUWELS, or 45 Mcore-h on SuperMUC-NG.

The GCS Peer Review Board took the decision to award large-scale project status to 16 projects from various scientific fields. Three projects were granted 1130 Mcore-h on Hawk, eight projects were granted 408,000 EFLOP on JUWELS, and five projects were granted 277 Mcore-h on SuperMUC-NG.
