Early warning two hours in advance

Realize personnel "0 casualties"

At around 4 am on August 23, due to the short -term heavy rainfall, Qing Diaolou, Zhangjiapingzigou, Eagle Rockgou, and Wangjiapo were located in Qunjiaping Zigou, Eagle Rockgou, and Wangjiapo respectively. As a result, 172 households were affected by 36 households and more than 600,000 yuan in economic losses. Due to the timely warning and the evacuation of the personnel in advance, no casualties were caused.

In this disaster, the “Mountain Disaster Risk Simulation and Danger Forecast System” used independently developed by the Chengdu Mountains of the Chinese Academy of Sciences, with the complementive linkage of the Geological Disaster Meteorological Risk Dispost of the Geological Disaster Meteorological Risks built by the Provincial Institute. Geological disaster monitoring and early warning platforms and Liangshan state geological disaster work class issued early warning information 2 hours in advance, which won valuable time for local government organizational personnel to evacuate and evacuate, and achieved refined forecast early warning and "0 casualties".

The "mountain disaster risk simulation and danger forecast system" conducts business operations with the Sichuan Provincial Meteorological Bureau, the Sichuan Provincial Department of Natural Resources and Liangshan Prefecture local governments. In 2022, the warning has been successfully warned, including many floods and mudslides such as Langhuan Town and Jinyang County in Liangshan Prefecture.

Global top ten

"Gods", super strong!

Behind the precision forecast, the computing power support of the National Supercomputing Chengdu Center (hereinafter referred to as: Chengdu Supercomputing Center) is inseparable.

In 2021, the Chengdu Supercomputing Center completed technical adaptation and transplantation for the specific needs of the Ministry of Water Resources and Environment of the Chinese Academy of Sciences. The problem of high incidence of mountain disasters caused by excessive rainfall during the flood season and insufficient computing force caused insufficient computing strength, which greatly enhanced the simulation accuracy.

It is understood that based on the large -scale parallel computing algorithm of the Chengdu Supercomputing Center CPU and DCU, the calculation efficiency of a single mudslide channel has increased by about 30 times the efficiency of the calculation of conventional models. The whole process simulation.

At present, the computing power of the Chengdu Supercomputing Center can reach 1 billion times per second, and the host performance ranks among the top ten in the world. Since it is launched in September 2020, the Chengdu Supercomputing Center has adhered to "based on Chengdu, radiating the west, facing the whole country, facing the country throughout the country. ", Provided computing power services for more than 760 users in 35 cities including Beijing, Shanghai, Guangzhou, and Chongqing. The service field covers 30 areas such as aerospace, equipment manufacturing, new materials, and artificial intelligence. Observation stations including 13 major national scientific and technological infrastructure and national topics. At the same time, Chengdu Supercomputing Center completed more than 19 million users' computing tasks, assisting in attracting more than 80 enterprises.
