Large-Scale Projects

Large-scale projects and highly scalable parallel applications are characterised by large computing time requirements, not only for short time frames, but frequently for longer time periods. The GCS centres will guarantee that large-scale projects can fully utilise the assigned resources, if necessary at the expense of normal or smaller projects.

Projects are classified as "Large-Scale", if they require more than 5% of the potentially available CPU cycles on a member centre's high-end system, i.e.

• more than 70 Mill. CPU-hours at JSC (corresponding to 24 rack months IBM Blue Gene/P)
• more than 4 Mill. CPU-hours at LRZ (SGI Altix 4700)
• more than 75000 Vector-CPU-hours at HLRS (NEC SX series)

Calls for large-scale scientific projects by the Gauss Centre for Supercomputing are issued twice a year. Dates for closure of calls are usually at the end of February and at the end of August of each year.

These projects were awarded "large-scale" status:
