"Apex" supercalculation Oak Ridge National Laboratorywebsitechart

"the Light of Shenwei Lake Taihu" is very touching to the United States.

"the Light of Shenwei Lake Taihu" is a supercomputer developed by the National Center for concurrent computer Engineering and Technology. On June 20, 2016, at the Frankfurt International Conference on supercomputing, the "Light of Taihu Lake Shenwei" supercomputer system topped the list. Become the world's first supercomputer with a speed of more than a billion times. Since then, the Chinese team has won the Gordon Bell Prize for two major applications, the Global Atmospheric Non-hydrostatic Cloud Resolution Simulation and nonlinear Seismic Simulation.

Professor Yang Guangwen, a professor at Tsinghua University and director of the National Super Computing Wuxi Center, said in an exclusive interview with the Science and Technology Daily that these achievements made by China over calculation are very touching to the US government and research institutions, and it can also be said that The advent of Shenwei Taihu Light prompted the United States to invest more in the development of a new generation of supercomputers.

"High performance computing is crucial to national security, economic competitiveness and the ability to cope with scientific challenges. If it is insufficient, it is difficult to maintain a continuous lead in the development of science and technology." Yang Guangwen pointed out that the United States must continue to maintain its status as a global superpower and need to return to the top in the field of supercomputing.

Before the reporters learned that although China has maintained the world's number one over the past 5 years, it is difficult for us to "top", and the United States is the biggest "rival". All the time, the US has the highest level of research and development in the world. As long as the budget is sufficient, the United States is the first time problem to return to the world, and the following will be the first scene of the United States, China and Japan.

The "vertex" uses 4608 calculationsThe server

The United States was originally planned to launch the "vertex" in November last year. In order to ensure the United States to return to the top of the supercomputer field, Oak Ridge National Laboratory and related cooperation institutions have been repeatedly demonstrating and improving the storage, power, algorithm, fault tolerance, application support and so on, so that the "vertex" can truly become the world's highest performance supercalculation.

Experts said that the "peak" of the United States should adopt a multi-core acceleration plan. The floating point operation speed of the vertex can reach 20 billion billion times per second. Among them, 4608 computing servers are used, each of which contains 22 nuclear Power9 processors produced by international commercial machines and 6 Tesla V100 graphics processing unit accelerators produced by Nvidia Corp, which can be used in research in the fields of energy and advanced materials, and can also run machine learning and deep learning. Artificial intelligence algorithm.

The Vertex is almost twice as fast as the Light of the Taihu Lake. Yang Guangwen pointed out that "the Light of Shenwei Lake Taihu" represents the level of our country's development in the year 2015. In recent years, we have made a series of important achievements in application, but each system needs to be optimized and perfected in the actual operation process, and its experience is summed up. For the new generation of systems to provide reference. He said that the current calculation and storage resources of "Shenwei Taihu Light" are operating at full capacity, and that the next step is to expand the capacity of computing and storage resources if funds permit.

A E level machine will come out around 2021

E supercomputing is recognized as the next world champion in the world. It will play an important role in solving the energy crisis, pollution and climate change.

"class E supercomputers are supercomputers that perform billions of mathematical operations per second. The supercomputer is 8 times faster than the light of Shenwei Lake Taihu. It mainly meets the needs of global climate change simulation, the processing of astrophysical big data, the simulation of the evolution of the universe, the verification of new materials, and so on. As a result, developed countries are preempting development opportunities. " Yang Guangwen said.

At present, the world's supercomputing powers are speeding up the layout of the next generation of supercomputing, and all countries are preparing for the development of E class machines. It is expected that by 2021, E machines will be available. Yang Guangwen said the next champion is now uncertain.

At present, our country is deploying the core problem to solve the supercomputer hardware and software. In Yang Guangwen's view, China has a great chance to surpass again in the era of E. Experts suggest that the relevant government departments should deploy the development tasks of the E level system as soon as possible, and increase the support for the R & D and supercomputing centers of the application software.
