The European HPC Ecosystem

“To out compute is to out compete" - The European HPC strategy

Over the last decades, the availability and usability of HPC systems has become one of the determining factors for the progress of science and a strategic resource for Europe's future. The accuracy of the analysis, the quality of the results and the potential of national and international collaborations are more and more depending on the available computing infrastructure - not only in climate science, but in science and industry in general. Mastering advanced computing technologies from hardware to software has become essential for innovation, growth and jobs.

Thus, the EU has set up an European HPC strategy and established a strong cooperation (based on contractual Public-Private Partnership on HPC (cPPP on HPC)) with the HPC stakeholders, represented by the the European Technology Platform for HPC (ETP4HPC). This cPPP on HPC has developed an ambitious R&I funding strategy, addressing

  • HPC facilities via the Partnership for Advanced Computing in Europe (PRACE), established since October 2012
  • HPC technologies via the Future and Emerging Technologies (FET) programme
  • and HPC applications via the establishment of Centres of Excellence (CoEs); the CoEs are funded via the e-infrastructures programme which aims to address the needs of European researchers for digital services in terms of networking, computing and data management.

To support and coordinate the collaboration and interactions, ETP4HPC together with PRACE and partners from the European Exascale Software Initiative (EESI2) have initiated the European eXtreme Data and Computing Initiative (exDCI).

Placing Climate and Weather Science in the European HPC ecosystem

The climate community is collaborating and participating in all three funding pillars of the EU (as shown in the Figure 1). The European Network for Earth System Modelling (ENES) provides infrastructures to the community, originally through the IS-ENES projects. Together with the weather community, the Center of Excellence in Simulation of Weather and Climate in Europe (ESiWACE) could be initiated and started in September 2015; the HPC Task force of ENES is exploring the feasibility to apply for dedicated access on PRACE for highend experiments within the international CMIP6 experiments. Synergies are elaborated with the FET HPC project ESCAPE (Energy-efficient Scalable Algorithms for Weather Prediction at Exascale), initiated by the weather community.
