The actual measurement results of the supercomputing prototype system of the China SKA Regional Center have been announced. How is the performance?

On November 29, at the SKA Shanghai Conference and the 6th SKA Engineering Conference, Huawei and the Shanghai Astronomical Observatory of the Chinese Academy of Sciences (hereinafter referred to as the “Shanghai Astronomical Observatory”) built the China SKA Regional Center Supercomputing Prototype System The actual measurement results were announced. Compared with the traditional platform, the performance of the massive continuum data generated by the pilot telescope MWA is improved by 2.23 times.

The conference was organized by the Ministry of Science and Technology of the People’s Republic of China and SKA, and jointly organized by the National Remote Sensing Center (SKA China Office) and the Shanghai Observatory. It attracted hundreds of engineers, scientists and industry representatives from 19 countries and regions around the world. Construction and operation of radio telescopes, with topics ranging from procurement, commissioning and operation, as well as discussions of related scientific topics.

In the live speech session of the conference, researcher An Tao from the Shanghai Astronomical Observatory announced the test results of the supercomputing prototype system, saying that the TaiShan server based on Huawei’s self-developed Kunpeng processor has obvious advantages in memory bandwidth, multi-core, low energy consumption, and open ecology. features. Among them, especially in the test with the MWA GLEAM imaging process as an example, the test performance of the TaiShan server is 2.23 times higher than that of the traditional computing platform; in many SKA high-throughput application scenarios, the server compatible with the ARM architecture will There are broad application prospects.

The SKA project is one of the largest international cooperative scientific projects in the field of astronomy. Its observation facilities will be distributed in the southern hemisphere and two continents, providing a major opportunity for mankind to understand the universe in detail. It is estimated that the SKA project will generate 10 times the data traffic of the current global Internet. In the face of EP-level computing and EB storage requirements, the supercomputing architecture will face scalability, affordability, stability, and flexible adaptation to advanced algorithms. sexual challenges. Huawei provided solutions including TaiShan HPC and Atlas 900 AI clusters for SKA’s astronomical data analysis. Among them, the prototype based on the TaiShan HPC solution uses the TaiShan 200 server based on the Kunpeng processor as the main computing node and the management node, and is compatible with Atlas heterogeneous nodes and x86 nodes based on the Ascend AI processor. Reionization, spectral line, continuum imaging, pulsar search, galaxy classification, transient source search, etc., realize independent shared storage and task scheduling within the data island, adopt diverse platforms for diverse services, and connect data islands through high-speed networks Interconnection, flexibly reorganize resources, achieve high flexibility and stability, and cooperate with the data storage management system and execution framework developed by the SKA community to jointly deal with the processing of massive astronomical data.

At the same time, thanks to the accelerated application of AI in the field of astronomy, SKA will also use Atlas 900-based cloud services for data analysis of radio telescopes, shortening the original 169-day feature star retrieval task to 10 seconds. Atlas 900 represents the leading level of AI computing in the world today. It consists of thousands of Huawei self-developed Ascend 910 AI processors, with a total computing power of 256P-1024P FLOPS @FP16, equivalent to the computing power of 500,000 PCs.

China is an important founding member of SKA Observatory and has made outstanding contributions in SKA engineering technology and scientific research. At present, researcher An Tao of Shanghai Observatory, as the Chinese representative of SKA regional center, participates in the overall design of global SKA regional center, and has completed the global SKA regional center. The first prototype of the SKA Regional Center. Huawei and Shanghai Astronomical Observatory share and exchange resources based on their respective advantages, and combine their advantages in radio astronomy, big data, cloud computing, high-performance computing, and artificial intelligence to jointly promote the construction of China’s SKA regional center and gradually develop it into the world First-class SKA main academic center and technology research and development center.
