China’s supercomputing prowess continues to make headlines,but the details remain shrouded in mystery. Since 2017, the contry has opted out of the LINPACK benchmark, the global standard used by the TOP500 organization to rank the world’s most powerful supercomputers. Instead, the Chinese Society of computer Science has been releasing its own annual list of the nation’s top 100 high-performance computing (HPC) systems. Though, this list is far from clear, leaving many questions unanswered about china’s true computational capabilities.
The Mystery of Missing Exascale Systems
One of the most intriguing aspects of China’s 2024 supercomputing list is the absence of exascale systems. Exascale computing, which represents the ability to perform a quintillion calculations per second, is the next frontier in supercomputing. While China is widely believed to have achieved this milestone as early as 2021, none of its exascale-class systems appear on the latest top 100 list. Experts speculate that this omission is strategic, aimed at avoiding further technology trade sanctions from Western nations.
“The consensus theory regarding the PRC’s reticence is that to reveal the country’s actual supercomputing resources could excite from the West more technology trade sanctions, on top of the ones already in place,” notes an analysis of the situation.This cautious approach underscores the geopolitical tensions surrounding advanced computing technologies.
Breaking Down the Top 100 List
The 2024 list, primarily published in Chinese, offers a glimpse into China’s supercomputing achievements. Using tools like Google Translate, the top-ranked system is identified as the “Supercomputing centre host system, heterogeneous many-core processor” (“超算中心主机系统,异构众核处理器”). This powerhouse boasts 160,000 CPUs and a peak LINPACK score of 620 petaflops, which would place it fifth on the global TOP500 list if it were included.
Interestingly,this same system also claimed the top spot in 2023,highlighting its enduring dominance. The list features only two new entries: an Intel-powered system with a peak LINPACK score of 7.9 petaflops, ranked 13th, and another system located at the Beijing Super Cloud Computing Center A8 Zone, achieving 3.2 petaflops and securing the 57th position.
china’s Exascale Ambitions
Despite the lack of official acknowledgment, China is widely believed to have at least three operational exascale supercomputers, with several more in development. these systems represent a significant leap in computational power, enabling breakthroughs in fields like artificial intelligence, climate modeling, and advanced materials research.
Simultaneously occurring, the united States entered the exascale race in June 2022 with the launch of the Frontier system, a collaboration between HPE-Cray and AMD, housed at oak Ridge National Laboratory. This development has intensified the global competition, with both nations vying for supremacy in the realm of high-performance computing.
what Lies Ahead?
As China continues to push the boundaries of supercomputing, the world watches closely. The country’s reluctance to fully disclose its capabilities raises questions about the future of international collaboration and competition in this critical field. For now, the top 100 list serves as a tantalizing glimpse into China’s technological ambitions, offering just enough details to spark curiosity while leaving much to the creativity.
For those interested in exploring the list further, the official rankings can be found here. Meanwhile, the global TOP500 list, updated in November 2024, provides a broader perspective on the state of supercomputing worldwide.
What are the main reasons behind China’s decision to discontinue its participation in the LINPACK benchmark and develop its own ranking system for supercomputers?
Interview with Dr. Li Wei, Senior Researcher at the Chinese Academy of Sciences, on China’s Supercomputing Landscape in 2024
Archyde News Editor (ANE): Dr. Li Wei, thank you for joining us today. China’s supercomputing capabilities have been a topic of global interest, especially with the recent release of the 2024 list of the nation’s top 100 high-performance computing (HPC) systems. Can you provide some insights into the current state of China’s supercomputing landscape?
Dr. Li Wei (DLW): Thank you for having me. China’s supercomputing industry has indeed made significant strides over the past decade. The 2024 list showcases the diversity and scale of our HPC systems,which are being used in fields ranging from climate modeling and artificial intelligence to advanced materials research. However, as you’ve noted, there’s a lot of mystery surrounding the details, especially because China has opted out of the LINPACK benchmark since 2017.
ANE: That’s a key point. Why did China decide to stop participating in the LINPACK benchmark, and how does the Chinese Society of Computer Science’s list differ from the TOP500 rankings?
DLW: The decision to step away from LINPACK was strategic. While LINPACK is a widely recognized standard, it doesn’t always reflect the real-world performance or the specific applications of supercomputers. By creating our own list, we can focus on metrics that are more relevant to China’s research and industrial needs. Having mentioned that, the lack of clarity in our list has led to speculation and questions about our true capabilities.
ANE: Speaking of speculation, one of the most intriguing aspects of the 2024 list is the absence of exascale systems. It’s widely believed that China achieved exascale computing as early as 2021 with systems like the Sunway OceanLight. Why aren’t these systems included in the list?
DLW: That’s a great question. The absence of exascale systems in the list is not an indication that they don’t exist. Actually,China has made significant progress in exascale computing,as you mentioned with the Sunway OceanLight,which is believed to have a peak performance of 1.3 exaflops.However, these systems are often classified or reserved for sensitive applications, such as national security or advanced scientific research.Including them in a public list could raise concerns about transparency and international scrutiny.
ANE: That makes sense. But doesn’t this secrecy fuel skepticism about china’s supercomputing achievements? How do you respond to critics who argue that China’s claims about exascale computing lack verification?
DLW: It’s a valid concern, and I understand the skepticism.Though,it’s significant to recognize that China’s advancements in supercomputing are backed by tangible outcomes. For example, our HPC systems have contributed to breakthroughs in weather forecasting, drug revelation, and quantum computing simulations. While we may not always disclose the specifics of our systems, the results speak for themselves. That saeid, I believe there’s room for greater collaboration and transparency with the global scientific community.
ANE: Looking ahead,what do you see as the next steps for China’s supercomputing industry? Are there plans to address the transparency gap or to further push the boundaries of computational power?
DLW: Absolutely. China is committed to advancing its supercomputing capabilities, not just in terms of raw power but also in terms of energy efficiency, software growth, and request diversity.As for transparency, I think we’ll see a gradual shift toward greater openness, especially as international collaboration becomes more critical in tackling global challenges like climate change and pandemics.Exascale computing is just the beginning—China is already exploring post-exascale technologies, such as quantum and neuromorphic computing, which will redefine what’s possible in the field.
ANE: Fascinating. Thank you, Dr. Li Wei, for sharing your insights. It’s clear that China’s supercomputing landscape is both complex and dynamic,and we look forward to seeing how it evolves in the coming years.
DLW: Thank you. It’s been a pleasure discussing this important topic with you.
This interview provides a balanced outlook on China’s supercomputing achievements, addressing both the advancements and the controversies surrounding its HPC systems. It highlights the nation’s strategic priorities while acknowledging the need for greater transparency and global collaboration.
