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.

192 GB of DDR4 memory/node,
Infiniband EDR interconnect network.
828 Intel KNL 7250 manycore nodes at 1.4 GHz with 68 cores per processor, for a total of 56,304 cores and a power of 2 Pflop/s,
96 GB of DDR4 memory + 16 GB of MCDRAM memory/node,
Bull eXascale Interconnect network (BXI).
Since the end of 2019, a second phase composed of Bull Sequana XH2000 cells adds the following partitions :
2292 dual-processor AMD Rome (Epyc) compute nodes at 2.6 GHz with 64 cores per processor, for a total of 293,376 computing cores and a power of 11.75 Pflop/s,
256 GB DDR4 memory/node,
Infiniband HDR100 interconnect network.
32 hybrid nodes with 2 Intel CascadeLake 20-cores 2.1 GHz processors and 4 NVIDIA V100 GPUs per node, for a total of 128 GPUs and a power of 1.13 PFlop/s.
As part of the Fenix project, the following partitions are also available :
30 hybrid nodes with 2 Intel CascadeLake 18-cores 2.6 GHz processors and 1 NVIDIA V100 GPU per node,
2 hybrid nodes with 4 Intel CascadeLake 18-cores 2.6 GHz processors, 3 To memory and 1 NVIDIA V100 GPU per node.
Common resources :
Irene hybrid : 20 vizualisation nodes with NVIDIA-P100 co-processors,
Irene xlarge : 5 so-called big memory/nodes for pre/post processing with 3 TB of memory/node and an NVIDIA-P100 co-processor,
A local storage, Scratch type, of 5 PB with a bandwidth of 300 GB/s.
Exploratory partition - ARM :
Based on Fujitsu PRIMEHPC FX700 technology : 80 DDR-less single-socket A64FX compute nodes (https://www.genci.fr/fr/node/1076).
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.
