December 4, 2015 - TERA 1000: CEA completes first milestone towards Exascale

The first phase of TERA 1000, the new pre-exascale supercomputer, has been delivered and installed by Atos at CEA/DAM (the CEA’s military applications Division). Completion of this first phase makes it possible to reduce energy consumption by a factor of five, compared to the previous supercomputer TERA 100 (1), while doubling its peak compute performance.

The compute needs of the CEA’s programs require the implementation of an exascale-class (2) supercomputer by 2020. To deliver a system of this size calls for technological breakthroughs. First, to control the electricity consumption of such a system. Secondly, to regulate the data throughputs and to master the huge quantity of data produced by simulations which are ever more precise, in order to model multi-physical and multidimensional phenomena.

To achieve this objective, CEA decided to apply from a very early stage a co-design methodology with Atos, in collaboration with Intel. The aim is to maximize performance by testing interactions between applications and the supercomputer. The CEA’s expertise covers several areas: from the code structure of applications through to code interaction with the supercomputer and up to the architecture of the supercomputer.
The first phase of TERA 1000 installed by Atos at the CEA’s DAM center near Paris includes two compute systems: the first is based on the Intel® Xeon® processor E5 v3 product family and the second is based on the latest generation Bull sequana X1000 system using pre-production Intel® Xeon Phi™ processors (formerly code named Knights Landing). By mid-2016 a very high performance Bull Exascale Interconnect (BXI) will significantly increase the global performance of the system. This system is a forerunner to the future generation of exascale supercomputers that will be implemented by 2020.

The second phase of TERA 1000, which will be up and running by 2017, will consist of 30 Bull sequana X1000 cells, integrating more than 8000 Intel® Xeon Phi™ Knights Landing processors connected by the very high performance BXI interconnect network. It will deliver a peak compute performance of 25 petaflops, with an energy efficiency 20 times better than Tera 100. Mastering the electricity consumption is a very significant milestone on the roadmap towards the exascale.

For François Geleznikoff, Director of Military Applications at CEA, « Tera 1000 is the third generation of supercomputers that stems from the partnership between Bull and CEA-DAM since the beginning of the 2000s. In the meantime, the computing power was increased by a factor of 5000, which contributes very heavily to the improvement of the forecast quality of the digital tools used for defense purposes, but also for industry and research. We are confident that this step opens the way to the exaflops system we need by 2020, with the targeted energy efficiency. »

Philippe Vannier, Executive Vice-President Big Data & Security and Chief Technology Officer of the Atos Group said, « The delivery of TERA 1000 is a key step in the implementation of our Exascale program. It is proof of the capacity of Atos to develop innovative solutions that will significantly reduce the electrical consumption of new generation supercomputers by 2020 – the systems that can reach the exaflops, i.e. a performance of one billion billion operations per second ».

Raj Hazra, Vice President and General Manager, Enterprise and HPC Platforms Group, Intel Corporation, “Intel is collaborating with CEA and Atos on the Tera 1000 project to bring exascale class computing to CEA’s codes. With a key focus on performance and power efficiency, the Intel® Xeon Phi™ processor – code named “Knights Landing” – together with the Intel® Xeon® process​or E5-2600 v3 product family can allow CEA and Atos to enable lower energy consumption while providing breakthrough levels of performance. This is a powerful processor combination that, in systems using the Intel® Scalable System Framework, will be central to meeting the supercomputing challenges of CEA’s Exascale program.”

(1) TERA 100, first system designed and built in Europe to reach the petaflops in 2010, was ranked in 5th position in the worldwide TOP 500
(2) exascale : exaflops range computing power (1 Flops = 1 FLoating-point Operations Per Second. The “peta” and “exa” prefixes indicate the number of operations per second : peta = 1015 one million billion ; exa = 1018 or one billion billion).

October 27, 2015 - High performance computing speeds up the low carbon energy transition

On October 5th and 6th, the EoCoE (Energy Oriented Center of Excellence) project was officially launched. EoCoE will use the tremendous potential offered by the ever-growing computing infrastructure to foster and accelerate the European transition to a reliable and low carbon energy supply.

EoCoE is one of the 8 centers of excellence in computing applications recently established within the Horizon 2020 programme of the European Commission.  The primary objective of all the newly formed Centres of Excellence is to help strengthen Europe’s leadership in HPC applications by tackling various challenges in important areas like renewable energy, materials modelling and design, molecular and atomic modelling, climate change, Global Systems Science, bio-molecular research, and tools to improve HPC applications performance.

With a total budget of 5.5 M€, EoCoE will assist the energy transition via targeted support to four carbon-free energy pillars: Meteorology, Materials, Water and Fusion, each with a heavy reliance on numerical modeling. These four pillars will be anchored within a strong transversal multidisciplinary basis providing high-end expertise in applied mathematics and High Performance Computing (HPC). EoCoE, led by Maison de la Simulation (France), is structured around a Franco-German hub (Maison de la Simulation - Jülich Research Centre) coordinating a pan-European network, gathering a total of 8 countries and 23 teams. Its partners are strongly engaged in both the HPC and energy fields.

The EoCoE project is lead by Maison de la Simulation, a joint lab betwenn CEA, CNRS, INRIA and the universities of Paris-Sud and Versailles. France is deeply involved in the project with participation of other teams from CEA, CNRS, INRIA CERFACS, EDF R&D and Méteo-France.

Septembre 8, 2015 - CEA: a strong commitment to European HPC

European Commission Horizon 2020 research framework clearly highlights HPC, with a 700 M€ programme under the umbrella of a cPPP (Public Private Partnership). This cPPP encompasses a strong technology branch but also provisions support for application enabling towards exascale, via Centres of Excellence for Computing Applications. The results of the first calls for HPC projects of H2020 have been known Spring of 2015, with CEA showing evidence of its involvement and excellence.

Almost all projects submitted by CEA - as coordinator or partner – have been accepted, forming a focused and consistent portfolio from technologies to applications:

  • ExaNode project (coordinated by CEA/DRT) will further develop active interposer processor architectures, bringing modularity and energy efficiency to high performance computing

  • SAGE (coordinated by Seagate/xyratex) is focusing on new storage concepts toward exascale; in this storage topic CEA is also a partner of BigStorage, one of the first Marie Curie actions granted in H2020

  • EoCoE is a Centre of Excellence for Computing Applications coordinated by Maison de la Simulation, dealing with numerical simulation for renewable energies; CEA has a strong involvement in EoCoE, as well as FZJ in Germany

CEA also recently signed a collaboration agreement with BSC, to coordinate efforts to reinforce European HPC research and technology innovation. BSC and CEA intend to jointly leverage their complementary, strong and global competencies from technologies to usages of HPC.
