Atos boosts supercomputing performance at German Climate Computing Centre (DKRZ) by 5 with new BullSequana

Paris, 22 June 2020

Atos, a worldwide leader in digital transformation, has signed a new 5-yr agreement with the German Weather Computing Centre (DKRZ) to source a supercomputer based mostly on its most recent BullSequana XH2000 technology to increase DKRZ’s computing electricity by five, in contrast to the at the moment functioning substantial-functionality laptop “Mistral” which was supplied by Atos in 2015. The new methods will be readily available at the DKRZ from mid-2021.

BullSequana to accelerate and produce much more specific forecasting

Just as a new, much more potent telescope provides much more in depth illustrations or photos from place, a much more potent supercomputer enables for much more in depth simulations and so further insights into climate functions. This sizeable increase in computing electricity will permit scientists at DKRZ to use regionally much more in depth climate and earth technique versions in future, to involve much more processes in calculations, to simulate for a longer time time periods, or to much more accurately seize pure climate variability utilizing ensemble calculations and so cut down uncertainties. This is accompanied by a strong increase in the facts that is calculated and then stored and evaluated. The BullSequana is an productive computing and facts administration answer, vital for climate modelling and the ensuing facts volumes, to endorse environmental exploration and produce much more reliable, in depth benefits.

Prof. Thomas Ludwig, CEO at DKRZ suggests: “Our substantial-functionality laptop is the coronary heart close to which our solutions for science are grouped. We’re truly satisfied to be operating with Atos all over again. With the new technique, our end users will be ready to attain new insights into the climate technique and produce even much more in depth benefits. This worries standard exploration, but also much more used fields of exploration these kinds of as enhanced latest climate projections. This way, we assist attain basic insights for climate change adaptation.”

Damien Déclat, Team VP, Head of HPC, AI & Quantum Business enterprise Functions at Atos, points out: “With our strong experience and working experience we have been ready to effectively style the DKRZ answer integrating it proficiently with the BullSequana XH2000 system’s greatest-of-breed components to improve DKRZ’s manufacturing workloads. We appear ahead to continuing this joint work to anticipate the upcoming phases as properly as to adapt apps and requirements to the upcoming processor era and other accelerating components.”

Atos is a specialist in the provision of leading technologies for some of the world’s leading centers in the Weather Forecasting and Weather local community, these kinds of as the European Centre for Medium-Range Weather Forecasts and the French Meteorological Assistance Météo-France and has worked intently together to improve apps, check out and anticipate new technologies, and appear for amplified effectiveness and diminished TCOs.

Complex specs

The Atos answer is based mostly on its BullSequana XH2000 supercomputer and will be one of the initial outfitted with the upcoming era of AMD EPYC x86 processors. The interconnect makes use of NVIDIA Mellanox InfiniBand HDR 200G technology and the facts storage answer relies on DDN machines. The final technique will consist of close to three,000 computing nodes with a complete peak functionality of sixteen PetaFlops, 800 Terabytes primary memory and a 120 Petabytes storage technique.


The new technique is really worth 32.five million euros, which is remaining supplied by the Helmholtz Association of German Study Centres, the Max Planck Society and the Cost-free and Hanseatic City of Hamburg.

About DKRZ

The German Weather Computing Heart (Deutsches Klimarechenzentrum, DKRZ) is a central provider center for German climate and earth technique exploration. Its substantial functionality desktops, facts storage and solutions form the central exploration infrastructure for simulation-based mostly climate science in Germany.

Apart from supplying computing electricity, facts storage potential and technical aid for versions and simulations in climate exploration, DKRZ presents its scientific end users an extensive portfolio of tailor-made solutions. It maintains and develops software software package pertinent to climate exploration and supports its end users in issues of facts processing. Ultimately, DKRZ also participates in national and worldwide joint assignments and cooperations with the aim of improving upon the infrastructure for climate modeling.

DKRZ was founded on November 11, 1987 and took up its solutions on January one, 1988. It is a non-revenue and non-business confined company with 4 shareholders:

  • The Max Planck Society
  • The Freie und Hansestadt Hamburg, represented by the University of Hamburg
  • The Alfred Wegener Institute – Helmholtz Centre for Polar and Maritime Study
  • and the Helmholtz Zentrum Geesthacht – Centre for Supplies and Coastal Study (HZG)

In addition, DKRZ is sponsored by the Federal Ministry of Training and Study and the The Helmholtz Association of German Study Centres.

DKRZ provides its assets (computing time, difficult-travel storage and archive potential, consultancy and visualizations) free of charge. Any scientists conducting exploration in the industry of climate and earth technique science in Germany, and demanding HPC assets for their work may utilize for assets at DKRZ.

DKRZ engages about 80 workforce, generally with a track record in pure and/or laptop sciences and is devided into three scientific departments
