Mistral: Final expansion stage of the high-performance computer at DKRZ starts operation

08.07.2016

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.

Since 1993 the performance of the world’s Top500 computers, including those of DKRZ, has risen by a factor of about a 1,000,000. Mistral is at rank 33 on the Top500 list (June 2016).

DKRZ

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.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
