Mistral on rank 55 of TOP500 list

On the opening day of the International Supercomputing Conference (ISC), which took place in Frankfurt from June 24 to 28, the TOP500 list of the most powerful supercomputers was traditionally published. The HPC system Mistral at the DKRZ is, two years after it was put up in operation, listed on rank 55 and is Germany's sixth largest supercomputer.

In addition to the publication of the TOP500 list, the 3,500 participants were given a broad range of topics in the field of high-performance computing during the ISC - including Excacale systems, quantum computers, big data analytics, climate change, cloud computing, artificial intelligence and programming models and languages. The DKRZ participated again with numerous actions in the conference program and the exhibition of the ISC'18.

At its booth L-440 in the ISC'18 exhibition, DKRZ informed about its infrastructure as well as its services for model-based climate simulations. A monitor displayed latest visualizations, including wind speeds, Arctic sea ice cover, sea level changes and currents, or garbage accumulations in the ocean. An interactive touch-screen could be used to explore high-resolution global weather simulations calculated by climate researchers using the ICON NWP model and a resolution of 2.5 km (84 million cells per shift). The simulation was carried out in the DKRZ-coordinated European Center of Excellence ESiWACE. The model was optimized within the framework of the BMBF project HD(CP)2 for an extremely high scalability.

Another poster presentation about From Molecular Dynamics towards a Node-Level Auto-Tuning Library for N-Body Simulations was presented on June 25 at the PhD Forum by Philipp Neumann. On June 26, he spoke about the topic Towards Global Cloud-Resolving Weather and Climate Prediction at Exascale during the session Tornados, Disaster & Early Warnings.

On June 26, among others Joachim Biercamp as the project coordinator reported about ESiWACE during the Birds of Feather Session ESiWACE: What is Special about HPC Computing for Weather and Climate? that was organized by Oliver Perks and Reinhard Budich (Max-Planck-Institut für Meteorologie).

During the session Visualization and HPC on June 25 at 5pm Michael Böttinger spoke about Visualization in Earth System Research - Current Status and Challenges imposed by HPC Trends.

On June 26 from 11:00 to 12:30 Philipp Neumann co-chaired the Research Paper Session AI & Machine Learning / HPC Algorithms.

Prof. Thomas Ludwig was one of the speakers during the full-day Workshop on Sustainable Ultrascale Computing Systems.

The team of the group Scientific Computing at DKRZ participated – as one of twelve teams – in the Student Cluster Competition. The student Leonhard Reichenbach reported on the cooperation of the group "Scientific Computing" with Docker Inc. at the High Performance Container Workshop.
