CERFACS is participating in the Allons-y à vélo initiative!

  16 January 2019

CERFACS is participating in the Allons-y à vélo initiative! (AYAV) The next edition will take place from 21 to 25 January. Let's go by bike means leaving your car in the garage, working on your legs and getting some fresh air! By promoting the use of bicycles as a means of daily commuting to and from work, CERFACS affirms, alongside 2 pieds 2 roues association, its willingness to participate in the effort to protect the environment. Actions in support of biking at CERFACS, such as the IKV (Indemnité Kilométrique Vélo), are listed on the CERFACS website along with activities organised as part of AYAV. Like CERFACS, Go by bike !

Cerfacs rewarded by two prices at the Safran Aircraft Engines R&T day – 17 December 2018

  19 December 2018

On Dec 17th, Cerfacs participated to the R&T Safran Aircraft Engines day during which Safran AE and their partners presented their research and development work. Cerfacs research was presented on various posters providing a general overview of numerical simulation activities performed with Safran in the fields of combustion chamber, compressor, turbine and numerical methods. Five CERFACS Phd student (CIFRE) also presented their work in 180 seconds. Over the 6 prices attributed to Safran AE partners, Cerfacs was awarded by the contract agility price. This price was awarded for the partner delivering fast responses to consultations and allowing quick and easy contract setup. Finally, Félix Collin-Bastiani received a prize for  his Phd research on modeling and simulation with large eddy simulation of ignition processes in two-phase flow and real-world conditions.

Professor Andrea Saltelli Seminar at CERFACS, December 3rd, 2018 Summary

  4 December 2018

CERFACS was pleased to welcome Pr. A. Saltelli for a wide interest seminar an Uncertainty Quantification. Pr. Andrea Saltelli's main disciplinary focus is on sensitivity analysis. The main idea behind sensitivity analysis is to figure out how the uncertainty in the output of a model can be apportioned to different sources of uncertainty in its inputs. Pr. Saltelli has worked on various fields of application such as physical chemistry, environmental sciences, applied statistics, impact assessment and science for policy. At present he is adjunct professor at the Centre for the Study of the Sciences and the Humanities at University of Bergen. He is currently a visiting fellow at Open Evidence Research at the Universitat Oberta de Catalunya in Barcelona. The talk was entitled "Are the results from a particular model more sensitive to changes in the model and the methods used to estimate its parameters, or to changes in the data". It reviewed some principles of sensitivity analysis, good and bad practices, and some practitioners' insight on when to use what. The stream line for the talk is available here

CERFACS awarded two projects to explore and disseminate new technologies for sustainable programming for exascale

  3 December 2018

CERFACS is now part of the Excellerat Center of Excellence () and the EPEEC project (). EPEEC aims ot bring european parallel programming technology to the exascale era.  It consist of 10 leaders in research and applications from Europe. EXCELLERAT is a European Centre of Excellence for Engineering Applications. The Centre is an initiative of several European High Performance Computing Centres to team up to support several key engineering industries in Europe in dealing with complex applications using HPC technologies.  It conducts  research, provides leadership, guidance on good practice, and user support mechanisms . Its goal is to help Europe leverage scientific progress in HPC driven engineering and address current economic and societal challenges.

Cerfacs funded for the EoCoE-II European center of excellence

  11 October 2018

The European center of excellence EoCoE-II brings together 20 partners from 7 European countries around exascale computing for energy-oriented numerical models. As a follow-up to the proof-of-principle phase of EoCoE (energy-oriented center of excellence), EoCoE-II will build on its unique, established role at the crossroads of HPC and renewable energy to accelerate the adoption of production, storage and distribution of clean electricity. Involved in 2 work packages, Cerfacs will conduct research around scalable multigrid solvers for the gyrokinetic fusion code GyselaX on the one hand, and surrogate models for uncertainty quantification and data assimilation with 2D hydrodynamics solvers on the other hand.

Cerfacs funded by the EU for more than 1 MEuros thanks to the IS-ENES3 and ESiWACE2 projects

  4 October 2018

IS-ENES3 is the third phase of the distributed e-infrastructure of ENES (European Network for Earth System modelling), enabling the European climate modelling community to address the challenges of international intercomparison project CMIP6. IS-ENES3 will develop, document and deploy new and advanced models and tools, standards and services to deal with unprecedented data volumes and model complexity. The Centre of Excellence ESiWACE2 brings together 20 partners from 9 European countries and plans to further push Earth System Model technology towards execution on upcoming pre-exascale and exascale systems. These two projects will finance Cerfacs activities around code coupling, in particular the further development of the OASIS coupler, upstream technical developments for climate services (climate4impact portal) and for the Earth System Grid Federation (ESGF) ensuring the dissemination and analysis of model output and observational data.

New supercomputer opened at Cerfacs

  16 May 2018

Since the beginning of May 2018, a new supercomputer named Kraken has been setup to reinforce Cerfacs' simulation capabilities. With a peak performance of 315 Tflop / s this new computer provided by Lenovo is now available to all of Cerfacs' researchers in addition to the Nemo computer. The Kraken cluster includes 119 compute nodes, each of them with two Intel Xeon Gold 6140 processors (18 cores skylake processor at 2.3 Ghz) and 96 GB DDR4 memory. This “compute partition” is completed by 3 post-processing nodes with 384 GB memory with a Nvidia Tesla M60 and one node with 768 GB memory used for large mesh generation. The interconnection network is a non-blocking Intel Omnipath Network.  

Support activity on C3Sm interface system for combustion codes of CERFACS rated first by SAFRAN HELICOPTER ENGINES (SHE)

  18 April 2018

Support activity on C3Sm, a software developed by CERFACS to use combustion LES codes has been rated first by an independent evaluation within SHE. This underlines the common work of SHE and CERFACS. C3SM was rated 70/70, far above the average value obtained by other tools used at SHE and especially well above commercial CFD codes.
