Czech Hydrometeorological Institute commissions NEC SX-Aurora TSUBASA supercomputer

TOKYO, February 11, 2021 – NEC Corporation announced today (February 12 in Tokyo) that the Czech Hydrometeorological Institute (CHMI) is commissioning a NEC SX-Aurora TSUBASA supercomputer. The recently deployed HPC solution is used for high resolution regional climate modeling.

The SX-Aurora TSUBASA supercomputer was delivered by NEC Deutschland GmbH in September 2020 and operational readiness was declared in December 2020. At the heart of the solution are 48 vector hosts containing 384 VE 20B type vector motor boards in one ( DLC), as well as a fully non-blocking high-speed interconnect based on Mellanox HDR InfiniBand network technology, and a total of 18 terabytes of HBM2 high-speed memory and 24 terabytes of DDR4 main memory. In addition, an HPC parallel storage solution based on the NEC LxFS-z storage appliance with a usable capacity of more than 2 petabytes has been deployed.

NEC has achieved a highly efficient DLC concept with cold water by combining state-of-the-art DLC and side cooler technology to prevent waste heat leakage into the computer room, allowing the entire system and environment to operate. without any additional air conditioning. in law. All in all, the complete solution even shows a much better energy efficiency than that originally defined by the requirements of the tender.

The new system will be used to simulate the future climate and how its changes will manifest. For example, it will help predict the future frequency and intensity of draft periods, and the end change of weather phenomena like flash floods and strong winds. The ultimate goal is therefore to help prepare for adaptation measures, by mitigating the impacts of climate change. In addition, it acts as a development system for the adaptation and optimization of certain meteorological codes and climatic applications which greatly benefit from vectorization on SX-Aurora TSUBASA.

“We are very happy to bring the new NEC SX-Aurora TSUBASA into service. For us, the NEC vector technology provided by SX-Aurora TSUBASA represents a very interesting alternative to competing HPC technologies, especially since we do not need to rewrite the majority of our production code. Another big advantage is the excellent ratio between the application performance gain factor and the energy consumption, ”said Dr Radmila Brozkova, head of the Numerical Weather Prediction department at CHMI.

“It is an honor for us that CHMI has chosen NEC for the delivery of our latest HPC solution, which clearly guides the way into the future of climate modeling and weather forecasting. CHMI is a very important customer to us, and we are happy to provide our strongest support not only for smooth operations, but also through performance that optimizes the climate applications used, ”said Yuichi Kojima, Managing Director of NEC Deutschland GmbH and vice president HPC.

About the Czech Hydrometeorological Institute

The Czech Hydrometeorological Institute is the central government institution of the Czech Republic for the fields of air quality, hydrology, water quality, climatology and meteorology, fulfilling this function as an objective specialized service. It was established in 1919 as the National Meteorological Institute. The current organization of the Institute also covers hydrology and air quality. The Institute is managed under the authority of the Ministry of the Environment of the Czech Republic and its main task is to establish and operate national monitoring and observation networks, create and maintain databases on the condition and quality of the air and on the sources. air pollution, the state and development of the atmosphere, as well as the quantity and quality of water, and to provide information on both climate and operation on the state of the atmosphere and hydrosphere, as well as forecasts and warnings alerting to dangerous hydrometeorological phenomena.
