Description

The European Union funds and coordinates large shared supercomputers through the EuroHPC Joint Undertaking.

Scope

  • Pre-exascale systems like LUMI (309 PFLOPS), LEONARDO (174 PFLOPS), and MareNostrum 5 (314 PFLOPS) provide significant baseline capacity.123
  • In 2025 the JUPITER exascale computer came online in Germany, adding roughly 8×10^18 INT8 operations per second.4

These resources total about 2×10^19 dense INT8 operations per second.

Implications

Expanded compute supports European research and industrial projects while reducing reliance on foreign cloud providers, but it also raises questions about equitable access among member states.
