Wave tide billions of magical tricks to calculate the South China Sea marine weather forecast

China Education Equipment Procurement Network News: Recently, China's leading high-performance server manufacturer Inspur successfully signed a contract with the South China Sea Institute of Oceanography, Chinese Academy of Sciences. Inspur Tiansuo TS10000 high-performance computing cluster will provide a high-performance and reliable supercomputing platform for numerical simulation of the South China Sea ocean and atmosphere. In order to improve the forecast accuracy of storm surges in the South China Sea offshore, to a greater extent reduce the economic losses and personal injuries caused by storm surges to the residents of the South China Sea offshore, and at the same time provide targeted climate prediction references for China ’s South China Sea Fleet travel, so as to provide A security barrier has been built in the South China Sea.

The South China Sea Institute of Oceanology, Chinese Academy of Sciences is one of the largest comprehensive marine research institutions in China, focusing on studying the structure and interaction characteristics and evolution of the ocean hydrosphere-geosphere-biosphere in the tropical marginal sea, and discussing its impact on resource formation and Control and impact of environmental changes, develop theoretical systems and applied technologies of tropical marine resources and environmental processes with the characteristics of the South China Sea Focus on promoting major breakthroughs in marine application technology, carrying out research and transformation of major scientific issues related to economic construction and social sustainable development in areas such as marine mineral resources exploration, utilization of marine living resources, evaluation and prediction of marine engineering environment and military environment, Make basic, strategic and forward-looking contributions to the development of China's marine economy and the protection of marine rights and interests.

The Inspur Tiansuo TS10000 high-performance computing cluster will provide services for the "South China Sea regional real-time sea-air numerical prediction test platform" of the South China Sea Institute of Oceanography, Chinese Academy of Sciences. The platform mainly forecasts 72-hour (short-term) and 15-day (mid-term) atmospheric conditions in the South China Sea and surrounding areas. The ocean circulation model uses a three-dimensional storm surge model with higher resolution, and uses the wind forecasted by the atmospheric model in the inner region. The field and air pressure field are used as the external forced field of the ocean storm surge model to carry out 48-hour storm surge forecast. The test platform realizes online real-time automatic acquisition of various analysis data required by the model's initial field and boundary field, and runs automatically every 6 hours, and can make predictions at 02, 08, 14, 20: 4 times a day. The “South China Sea Regional Real-Time Air-Sea Numerical Forecasting Experimental Platform” has repeatedly accurately forecasted natural marine disasters such as typhoons and storms, such as the intensity and moving path of super-strong typhoons “Vanyabi” and “Catfish”. Coastal residents reduced economic losses and casualties. The establishment of the "South China Sea regional real-time air-sea numerical prediction test platform" provides an important diagnostic analysis method for studying the South China Sea ocean circulation and vortex, the internal mixing of the ocean and the air-air interaction mechanism, etc. The "973" national key scientific and technological research project "South China Sea air-sea interaction and ocean circulation and vortex evolution law" smooth implementation and implementation of the necessary technical support and guarantee, but also for the future development of fully coupled high-resolution sea-air -The wave coupling mode and real-time data assimilation system lay the foundation.

In order to complete the system construction, the technical experts of the South China Sea Institute of Oceanography organized multiple rounds of discussion and discussion on application requirements and system construction. Taking into account the safety and importance of the research business and system, the project determined that the domestic high-performance computing vendors The construction-oriented idea, experts require that the domestic high-performance computing manufacturers participating in the project must have the same experience in high-performance computing system construction and software application experience, and it is best to have practical application cases, especially in the marine and atmospheric fields. Has a very rich ability and experience. Under this principle, experts from the South China Sea Institute of Oceanography conducted in-depth inspections of multiple domestic high-performance computing vendors, and organized selection of high-spec and high-requirement solutions. In the end, the experts unanimously selected Inspur to win the bid. So what advantages does Inspur stand out from various manufacturers, and ultimately assume the responsibility of building a high-performance computing system that predicts marine meteorology in the South China Sea?

1 Rich experience in supercomputing system construction and marine meteorology

During the 11th Five-Year Plan period, Inspur participated in the research and development of many domestic petaflop supercomputers such as the National Supercomputing Tianjin Center "Tianhe 1A" and the National Supercomputing Jinan Center "Shenwei Blu-ray", and accumulated a wealth of cutting-edge R & D experience. The 172 trillion "Earth System Simulator" custom designed by Inspur for Tsinghua University is an important supercomputing platform for China to study global climate change and has completed the calculation task of IPCC AR5. Inspur built a supercomputer for China Ocean University to help scientists in the ocean The field of environmental and meteorological research has achieved fruitful research results. Experts from the South China Sea Institute of Oceanography, after on-site inspection of the supercomputing systems of Tsinghua University and Ocean University of China, spoke highly of Inspur's supercomputing system construction technology level and leading application capabilities.

2 High performance and high reliability, the overall design performance exceeds 100 billion times

The overall design performance of this supercomputing system provided by Inspur for the South China Sea Institute of Oceanography, Chinese Academy of Sciences exceeded 100 billion times. The computing capacity of the first-phase system construction reached 50TFlops and the storage capacity reached 400TB.

The overall cluster large-scale deployment of Inspur high-density blade server NX5440, using powerful Intel Sandybridge series processors, each blade chassis can support 20 dual-socket blade nodes is the industry's highest computing density HPC blade, supports both dual and quad The blades are intermixed, supporting built-in redundant Infiniband high-speed switching modules, redundant Ethernet switching modules, redundant management modules, and all power supply fan modules. Redundant hot-swap is supported. The leading enterprise-level design allows blade servers to achieve high performance With the highest reliability to effectively avoid system failure.
