On June 28th, 2016, company Atos/Bull handed over the second expansion stage of supercomputer Mistral to the German Climate Computing Center (DKRZ) in Hamburg. Since July 4th, 2016, the third „High-performance computing system for Earth system research“ (HLRE-3), with a peak performance of approximately 3.5 quadrillion numerical operations per second, has been available to the climate research community.
On the TOP500 list of the most powerful supercomputers, which was published during the International Supercomputing Conference (ISC’16), the final expansion stage of Mistral at DKRZ occupied position no. 33 worldwide. At present, Mistral is the 5th most powerful high-performance computer in Germany.
On July 4th, 2016, the final expansion stage of the high-performance computing system Mistral has started its operation at the German Climate Computing Center (DKRZ) in Hamburg.
Roughly 3,000 compute nodes of type bullx DLC 720, provided by Atos/Bull, having a total number of more than 100,000 processor cores on the basis of Intel processors of types Xeon E5-2680v3 12C with a clock rate of 2.5 Gigahertz (Haswell) and E5-2695V4 18C with a clock rate of 2.1 Gigahertz (Broadwell) provide the computing capacity.
This is the largest high-performance computing system by company Atos/Bull on the TOP500 list. Due to the warm-water cooling system, which cools the CPU and main memory, Mistral is very energy-efficient: despite a 20-fold increase in performance compared to its predecessor, HLRE-II “Blizzard”, Mistral consumes slightly less electrical power.
In order to meet the very data-intensive requirements of climate modelers, the system stands out from most other high-performance computers by having an especially large and powerful parallel file system. Mistral’s parallel file system by company Seagate has a capacity of 54 petabytes and occupies position no. 2 on the vi4io.org list, which compares the largest file systems worldwide. The peak transfer rate of the Lustre-based file system is 450 Gigabytes/s. This is the data volume of approximately 100 full-length movies per second!
The entire system consists of about 80 telephone booth-sized cabinets, most of them weighing more than a ton, and being interconnected by bundles of fiber and high-performance network components by Mellanox.
Using Mistral, climate researchers are able to perform climate simulations at a higher resolution, to include additional processes in earth system models, or to reduce uncertainties in climate projections.
Computations are currently being planned for the extensive international model intercomparison project CMIP6 (Coupled Model Intercomparison Project Phase 6), thereby, for the German contribution to the next IPCC Report.
Another project examines the formation of clouds and precipitation in greater detail: Mistral enables scientists to perform high-resolution regional simulations at a grid resolution of only 100 meters all of Germany for the first time, ever. This facilitates the explicit computation of small-scale processes such as cloud formation and precipitation, which must be parameterized in coarser models.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
