IDRIS is a French national high-performance computing facility that provides supercomputing resources and services for scientific research, industrial simulation, and public-sector projects. Located near Orsay in Ile-de-France, IDRIS has hosted successive generations of supercomputers used by researchers affiliated with institutions such as the University of Paris-Saclay, Centre national de la recherche scientifique, Commissariat à l'énergie atomique et aux énergies alternatives, and international partners including CERN, European Space Agency, and European Centre for Medium-Range Weather Forecasts. The facility supports workflows ranging from computational fluid dynamics for Airbus and Dassault Aviation to climate modeling used by teams at the Météo-France and the Intergovernmental Panel on Climate Change.

Overview

IDRIS functions as a national infrastructure node within the French and European research landscape, interfacing with projects funded by entities like the European Commission, Agence nationale de la recherche, and collaborations involving the National Aeronautics and Space Administration and European Southern Observatory. Its user base includes academics from École Polytechnique, Sorbonne University, and Université Paris-Saclay, as well as engineers from companies such as TotalEnergies and Schneider Electric. IDRIS provides access to computing architectures that support codes developed at laboratories like the Institut Pasteur, CEA, and the Laboratoire de Physique Théorique, and contributes compute cycles to community codes such as GROMACS, LAMMPS, OpenFOAM, WRF, and ECMWF Integrated Forecasting System.

History

IDRIS traces its origins to early national computing efforts that involved organizations like Bull, the French Alternative Energies and Atomic Energy Commission, and the CNRS. Throughout the Cold War era it hosted generations of machines contemporaneous with systems at Lawrence Livermore National Laboratory, Los Alamos National Laboratory, and Rutherford Appleton Laboratory. In the 1980s and 1990s IDRIS upgraded hardware parallel to developments at Cray Research, IBM, and Thinking Machines Corporation, while participating in European initiatives alongside the PRACE partners and the GENCI consortium. Later milestones included procurement cycles involving vendors such as SGI, HPE, and Atos, integration with continental grids like EUDAT and Grid'5000, and service expansions aligning with programs from Horizon 2020.

Architecture and Capabilities

IDRIS deployments have featured architectures ranging from vector machines and scalar clusters to hybrid CPU–GPU systems and large-scale multicore nodes, paralleling architectures from Cray-1, Cray XT, IBM Blue Gene, Nvidia Tesla, and AMD EPYC based platforms. The center integrates high-performance storage solutions similar to Lustre, network fabrics inspired by InfiniBand and Intel Omni-Path, and middleware stacks interoperable with Slurm Workload Manager, Kubernetes, and OpenMPI. IDRIS supports parallel programming models used by projects with ties to MPI Forum, OpenMP Architecture Review Board, and Kokkos, enabling simulations in workflows developed for codes like ANSYS Fluent, ABAQUS, NWChem, and Quantum ESPRESSO.

Notable Projects and Applications

Researchers at IDRIS have contributed compute capacity to large collaborations and landmark studies, including cosmological simulations akin to work at the Max Planck Institute for Astrophysics and Lawrence Berkeley National Laboratory, particle physics analyses related to CERN experiments, and climate projections informing reports by the Intergovernmental Panel on Climate Change. Industrial partnerships include aerodynamic optimization for Airbus, reservoir simulation for TotalEnergies, and energy systems modeling used by EDF (Électricité de France). IDRIS has also supported bioinformatics pipelines used by teams at Institut Pasteur, structural biology projects comparable to research at the European Molecular Biology Laboratory, and machine-learning training runs similar to those conducted at Google DeepMind and OpenAI.

Performance and Benchmarks

Over successive procurements IDRIS machines have been ranked in lists comparable to the TOP500 and tested with benchmarks related to HPCG and Linpack. Historical performance has been referenced alongside machines from Oak Ridge National Laboratory, National Center for Supercomputing Applications, and Fujitsu installations. Benchmarking and application scaling studies at IDRIS examine throughput and efficiency for community codes such as GROMACS, CP2K, and ROMs, and for AI frameworks developed at Facebook AI Research, Google Brain, and DeepMind. Comparative metrics include sustained FLOPS, I/O throughput against systems using BeeGFS and Lustre, and energy efficiency measurements aligning with standards used by the Green500 list.

Governance and Funding

IDRIS is operated under the auspices of French national research structures including GENCI and the CNRS, with procurement and strategic coordination involving the Commissariat à l'énergie atomique et aux énergies alternatives and regional partners in Ile-de-France. Funding sources combine national allocations from ministries comparable to the Ministry of Higher Education and Research (France), competitive grants from agencies like the Agence nationale de la recherche, and European funding programmes such as Horizon Europe. Governance structures coordinate user access, allocation committees, and peer review panels similar to processes at the PRACE council and national allocation bodies, and facilitate partnerships with international centers including PRACE, NERSC, and HLRS.
