Joliot-Curie
One of the most powerful supercomputer dedicated to French and European research
The Joliot-Curie supercomputer was installed at the end of 2017 in the CEA's Very Large Computing Center (TGCC), located in Bruyères-le-Châtel (Essonne), following a purchasing procedure carried out by a team integrated GENCI-CEA. The implementation of Joliot-Curie within the TGCC, as well as its operation, have been entrusted to the operational teams of the CEA's Military Applications Division (DAM). It thus benefits from a cutting-edge scientific and technical environment.
With a processing capacity of 22 petaflops, Joliot-Curie is at the service of French and European researchers, through the European PRACE research infrastructure.

Quantum resources
TGCC aims to host quantum computing resources.
Emulators based on the software suites Qaptiva/EVIDEN, Pulser/PASQAL and Perceval/Quandela are already available to end users.
A PASQAL quantum computer, with a hundred of qubits, will be available in Spring 2024.
