Several centers for supercomputing exist across Europe, and distributed access to them is coordinated by European initiatives to facilitate high-performance computing. One such initiative, the HPC Europa project, fits within the Distributed European Infrastructure for Supercomputing Applications (DEISA), which was formed in 2002 as a consortium of eleven supercomputing centers from seven European countries. Operating within the CORDIS framework, HPC Europa aims to provide access to supercomputers across Europe.[1]

According to the TOP500 list of November 2023, Finland's LUMI is the fastest European supercomputer, followed by Italy's Leonardo[2]. Germany's JUWELS (booster module)[3] was the fastest European supercomputer in 7th place (followed by Italian Eni company supercomputer) in November 2020, and Switzerland's Piz Daint was the fastest European supercomputer, in October 2016, ranked 3rd in the world with a peak of over 25 petaflops.[4]

In June 2011, France's Tera 100 was certified the fastest supercomputer in Europe, and ranked 9th in the world at the time (has now dropped off the list).[5][6][7][8] It was the first petascale supercomputer designed and built in Europe.[9]

There are several efforts to coordinate European leadership in high-performance computing. The ETP4HPC Strategic Research Agenda (SRA) outlines a technology roadmap for exascale in Europe, with a key motivation being an increase in the global market share of the HPC technology developed in Europe.[10] The Eurolab4HPC Vision provides a long-term roadmap, covering the years 2023 to 2030, with the aim of fostering academic excellence in European HPC research.[11]

Pan-European HPC organisation[edit]

There have been several projects to organise supercomputing applications within Europe. The first was the Distributed European Infrastructure for Supercomputing Applications (DEISA). This ran from 2002–2011. The organisation of supercomputing has been taken over by the Partnership for Advanced Computing in Europe (PRACE).

From 2018-2026 further supercomputer development is taking place under the European High-Performance Computing Joint Undertaking within the Horizon 2020 framework. Under Horizon 2020, European HPC Centres of Excellence are being funded to promote Exascale capabilities and scale up existing parallel codes in the domains of renewable energy, materials modelling and design, molecular and atomic modeling, climate change, global system science, and bio-molecular research.[12][13]

In addition to advances being shared with the HPC research community such as the “Putting the Ocean into the Center” visualization[14][15] and progress on the “Digital Twin” that is already being used to run in silico clinical trials,[16][17] EU countries are already beginning to directly benefit from work done by the Centres of Excellence under Horizon 2020: In summer 2021, software from a European Centre of Excellence was used to forecast ash clouds from the La Palma volcano.[18] Additionally, EU Centres of Excellence are providing support throughout the Covid19 pandemic creating models to guide policy makers, expediting the discovery of possible treatments, and generally facilitating the sharing of research data during the race to understand the corona virus.[19] [20][21]

High performance computing tiers[edit]

PRACE provides "access to leading-edge computing and data management resources and services for large-scale scientific and engineering applications at the highest performance level".[22] PRACE categorises European HPC facilities into 3 tiers: Tier-0 are European Centres with petaflop machines, Tier-1 are national centres, and Tier-2 are regional centres.

PRACE has 8 Tier-0 systems:[23]

  1. JUWELS Booster (Germany)
  2. JUWELS Cluster (Germany)
  3. SuperMUC-NG (Germany)
  4. HAWK (Germany)[24]
  5. Marconi100 (Italy)
  6. Piz Daint (Switzerland)
  7. MareNostrum 4 (Spain)
  8. Joliot Curie (France).[25] Note that PRACE lists Joliot Curie KNL, Rome, and SKL separately but counts them as one system
