The Partnership for Advanced Computing in Europe (PRACE) is an international non-profit association (aisbl) with its seat in Brussels. The mission of PRACE is to enable high impact scientific discovery and engineering research and development across all disciplines to enhance European competitiveness for the benefit of society. PRACE seeks to achieve this mission by offering world class high performance computing (HPC), computing and data management resources and services for scientists and researchers from academia and industry in Europe through a peer review process. The Implementation Phase of PRACE receives funding from the EU’s Seventh Framework Programme (FP7/2007-2013) under grant agreement RI-312763 and from the EU’s Horizon 2020 Research and Innovation Programme (2014-2020) under grant agreements 653838 and 730913.

The computer systems (called Tier-0 systems) and their operations that are accessible through PRACE are provided for this 17th call by 5 PRACE hosting members: BSC representing Spain, CINECA representing Italy, CSCS representing Switzerland, GCS representing Germany and GENCI representing France.

Scientists and researchers can apply for access to PRACE resources. Industrial users can apply if they have their head offices or substantial R&D activity in Europe.

The Call is open to:
Project Access: Proposals can be based on a 12-months schedule (Single-year Projects), or, on a 24- or 36-months schedule (Multi-year Projects). The allocation of awarded resources is made 1 year at a time with provisional allocations awarded for the 2nd and 3rd year.

Additionally, the Call:
reserves 0.5% of the total resources available for this call for Centres of Excellence (CoE) as selected by the European Commission under the E-INFRA-5-2015 call for proposals.

The PRACE Access Committee, composed of leading international scientists and engineers, ranks the proposals received and produces a recommendation to award PRACE resources based on scientific and technical excellence.
