New GCS Large-Scale Projects Started in November 2021

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.

After computing time quantities were previously specified in core hours, the modularity of JUWELS requires the introduction of a new computing time unit. JSC is currently working with the peak floating point operations per year (FLOP/a) of the computing devices (CPU or GPU) available to approved projects. The computing time on Hawk and SuperMUC-NG continues to be given in core hours. Projects in this case fall into the category of large-scale only if they require at least 100 Mcore-h on Hawk, 45 x 1021 FLOP/a on JUWELS, or 45 Mcore-h on SuperMUC-NG.
The GCS Peer Review Board decided to award the status of a large-scale project to 15 projects from various scientific fields. In total, five projects were granted 955 Mcore-h on Hawk, six projects were granted 375 x 1021 FLOP/a on JUWELS, and four projects were granted 270 Mcore-h on SuperMUC-NG.
