EoCoE-III
26 October 2023
Cerfacs participates in the Energy-oriented Centre of Excellence (EoCoE-III), starting in early 2024. The project applies cutting-edge exascale computational methods in its mission to accelerate the transition to the production, storage and management of clean, decarbonized energy. EoCoE-III is anchored in the High Performance Computing (HPC) community and targets research institutes and key commercial players who develop and enable energy-relevant numerical models to be run on exascale supercomputers, demonstrating their benefits for the net-zero energy transition. The project will draw on the experience of two successful previous projects EoCoE-I and -II, where a large set of diverse computer applications from four such energy domains achieved significant efficiency gains thanks to a multidisciplinary expertise in applied mathematics and supercomputing. EoCoE-III channels its efforts into 5 exascale lighthouse applications in the low-carbon sectors of Energy Materials, Water, Wind and Fusion. This multidisciplinary effort will harness innovations in computer science and mathematical algorithms within a tightly integrated co-design approach to overcome performance bottlenecks and to anticipate HPC hardware developments. A world-class consortium of 16 complementary partners forms a unique network of expertise in energy science, scientific computing and HPC, including 3 leading European supercomputing centres. In particular, Cerfacs will take part in the research on fast solvers needed in numerical simulations in the plasma core-edge interactions in ITER-scale tokamaks.
Allons-Y A Vélo (Let’s cycle to work) : bronze medal for Cerfacs once
10 October 2023
For the 3rd time in 3 years, Cerfacs is on the podium of the "Allons-Y À Vélo" enterprise challenge in its category (100-500 employees) with a bronze medal for its cycling regularity during the AYAV period (May 29 - June 9 2023). During this period, 39% of Cerfacs employees came to work by bike during at least 5 consecutive days . Details about Allons-Y A Vélo can be found here. This nice success is in-line with Cerfacs participation to the Programme Employeur Pro-Vélo that provided fundings for new bike racks and bicycle repair workshops. In particular, Cerfacs employees benefit from the Forfait Mobilité Durable (FMD), i.e. up to 500 € for cycling to work!

Two Cerfacs’ talks at Teratec Forum
4 June 2023
CERFACS participated to the Teratec23 forum on High-Performance computing at the Parc Floral de Paris on May 31st-June 1st, 2023. This forum has welcomed international experts in Super Computing from all sectors of our society, such as Climate and Geosciences. As a leader in the landscape of Digital Simulation, CERFACS has taken part in two workshop sessions. Gabriel Staffelbach (HPC expert, CERFACS) was involved in "Quantum Computing: Future of HPC?" session. Sophie Ricci (Data assimilation expert, CERFACS/CNRS) and Thanh Huy Nguyen (Remote sensing expert, CERFACS/CNRS) were involved in the "HPC for the Earth Sciences, Climate and Environment" workshop. Gabriel Staffelbach delivered an insightful presentation on CERFACS' technology watch initiatives, with a specific focus on harnessing the potential of Quantum computer simulators and Quantum hardware for solving partial differential equations. The presentation highlighted the culmination of collaborative efforts spanning the past three years, involving key partnerships with Eviden (an Atos business) and IBM. In addition to this, CERFACS worked with the LIRMM laboratory to delve into the realm of quantum computing, leveraging their extensive experience in High-Performance Computing (HPC) as a solid foundation. This comprehensive exploration aims to unravel the advantages and drawbacks of quantum computing in the context of solving complex equations. S. Ricci and T. H. Nguyen gave a joint presentation with Raquel Rodriguez-Suquet (CNES, Lab'OT) on the FloodDAM-DT project. FloodDAM-DT (Flood Detection Alert and mapping - Digital Twin) is supported by the Space for Climate Observatory (SCO) program as a follow-up to its precursor FloodDAM within an international French-American cooperation. The international cooperation between CNES SCO FloodDAM-DT and NASA IDEAS project (AIST program) on water-cycle applications to devise an Earth System Digital Twin (ESDT) for alert and flood risk mapping systems at small and global scale to enable researchers and decision-makers to visualize, analyze, and evaluate different scenario outcomes for environmental matters where risk assessment is at stake. In this context, the targeted Digital twin architecture for Hydrology aims at dynamically connecting existing hydrologic/hydrodynamic models and continental water data (in-situ, airborne, remote-sensing (RS) data sources e.g. radar and optical) from both agencies (NASA & CNES) to produce large-scale flood predictions. This work entails a multi-agency effort to establish an extensible open-source platform focused on water resources and flood analysis where test case studies serve as demonstrators. This 18-month project will result in a Proof-of-Concept showcase where the processing blocks are assembled for the Garonne catchment in France and the Ohio catchment in the US, thus providing access to in-situ and satellite/drone data, flood extent mapping issued from data processing, and data driven modeling as well as associated flood socio-economic risk map.
The Chinese edition of ‘Theoretical and Numerical Combustion' (TNC) book available
2 June 2023
The TNC book is a classical textbook for engineers and researchers performing simulations of turbulent reacting flows. Its english version has been available for a long time but now, a Chinese version is also available here : TNC book is based on many results obtained first at CERFACS in the CFD team. Of course, finding typos is a little bit more difficult for most of us..

CERFACS participation in the European Aviation Safey Agency (EASA) Conference
5 April 2023
The European Aviation Safety Agency (EASA) organized a conference aimed at strengthening exchanges with academia on R&I topics that could, in the near future, change the world of aviation, contribute to the development of European industry, and address new regulatory challenges for aviation authorities. The conference was held in Cologne, Germany, on 23 and 24 March and brought together PhD students and other academic representatives with EASA experts and stakeholders, government and European research institutions.Three PhD students from the GLOBC team were invited to the conference to present their findings on the impact of climate change on aviation (ICCA), an active research topic at CERFACS and one of EASA's most important concerns. Victoria Gallardo (4th year) and Suzanne Salles (2nd year) study the impact of rising temperatures on aircraft take-off, whereas Mohamed Foudad (3rd year) focuses on the impact of global warming on clear-air turbulence. Suzanne Salles received the Young Doctoral Student Award for an invitation to visit EASA to work on her topic. More details in:
