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. Read more

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.   Read more

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. Read more

Invited communication to the BIDS'17 conference

12 December 2017

During an invited communication to the « Big Data from Space 2017 » conference, CERFACS presented the stakes and the perspectives of its strategic axis "Data Driven Modeling" from the point of view of the valorization of satellite data. For more details, see the article: Abstract: CERFACS has a long-established record of excellence in environmental and industrial Computational Fluid Dynamics for complex flow simulation on high-resolution grid enhanced by continuous developments in numerical models and in High Performance Computing. Data Assimilation of satellite data for ocean, atmospheric chemistry or hydraulics modeling is also one of its strong expertise domains. Uncertainty Quantification has become a developing field based on ensemble approaches and model-reduction objectives. Based on these expertise domains, a new challenge for CERFACS is to develop a Data Driven Modeling axis combining Data Science, Uncertainty Quantification and Data Assimilation. Reference: O. Thual et al, The stakes and prospects of “Data Driven Modelling” at CERFACS, 2017 Conference on Big Data from Space (BIDS’17), November 30th 2017, Toulouse, Read more
