The Supercomputing Showdown: China vs. the United States
Written on
Chapter 1: The Supercomputing Arms Race
In recent years, global powers have engaged in an intense competition in supercomputing technology.
Supercomputers and Their Geopolitical Importance
Supercomputers are typically defined as the 500 fastest computers globally, encompassing advancements such as quantum and exascale computing. At the dawn of the century, China had only two supercomputers in this elite category, neither of which ranked particularly high. Fast forward to 2010, and the landscape had dramatically shifted; China and the United States were nearly tied in the number of supercomputers within the top 500, with one of China's machines claiming the top spot as the fastest.
It's crucial to recognize China's extensive technological capabilities, which far exceed just Huawei, the leading global provider of information and communication technology (ICT) infrastructure and smart devices. Notably, China leads in hypersonic missile technology, rendering it largely impervious to military threats. Supercomputers represent the apex of information technology, showcasing another domain where China has not only kept pace with but often surpassed the United States.
Initially, China's supercomputers were constructed using off-the-shelf components, including processors from Intel. Following years of China maintaining its number one position, the U.S. imposed a ban on exporting Intel's top chips to China. This strategy backfired; within a year, China developed a new supercomputer that not only outperformed its predecessor but was also entirely built with domestically produced processors.
Currently, China holds a dominant position in the top-500 list with over 200 supercomputers—nearly double the number held by the United States. However, the U.S. retains ownership of the two fastest machines. China is now determined to reclaim the number one position, this time relying solely on chips and components manufactured within its borders.
Supercomputers are evaluated based on their performance measured in FLOPS, or floating-point operations per second. A computer capable of ten FLOPS can execute ten calculations in a second, which is insufficient for contemporary standards. Most modern laptops or desktops operate in the range of several teraflops, meaning trillions of calculations per second. The goal in supercomputing today is to construct the first exascale computer, which would execute a quintillion calculations per second—one million times faster than an average desktop, significantly enhancing scientific and artificial intelligence research.
Chapter 2: The Quantum Leap to Exascale
The next generation of supercomputers, known as exascale systems, is already making significant progress. These machines will be capable of performing at least a quintillion calculations per second. As reported by Oak Ridge National Laboratory on May 30, 2022, the U.S. appears to have an early advantage in developing the first exascale computer:
The Frontier supercomputer at the Department of Energy's Oak Ridge National Laboratory has been ranked as the fastest in the world on the 59th TOP500 list, achieving 1.1 exaflops of performance. This system is the first to reach an unprecedented computing level known as exascale—a threshold of a quintillion calculations per second. Frontier boasts a theoretical peak performance of 2 exaflops, making it ten times more powerful than ORNL's previous Summit system. The advanced capabilities of this system will enable scientists to create essential technologies for the nation's energy, economic, and national security needs, addressing challenges that were insurmountable just five years prior.
Section 2.1: Future Aspirations in Supercomputing
China is also looking ahead, aiming for the 2030s when it plans to unveil a generation of supercomputers that will be 1,000 times faster than current exascale machines, again using entirely Chinese-made components.
The competitive landscape reveals that China can more than hold its own in this technology race against the United States. However, it seems that for China, the competitive aspect is not the primary focus; rather, it is seen as secondary to larger global concerns. China does not view the world as a mere repeat of the 1950s and 1960s, where two superpowers vie for dominance. Instead, it recognizes that the real challenge today is addressing urgent global issues like resource scarcity, which affects all nations.
As such, cooperation among countries—not conflict—will ensure that advancements in technology benefit everyone. If the approach is not mutually beneficial, it risks leading to a lose-lose situation for all involved.
This perspective might explain why China has not reacted more aggressively to U.S. technology bans. It could have retaliated by restricting rare earth exports, which would severely disrupt U.S. technology manufacturing. Alternatively, it could have targeted major U.S. companies like Qualcomm, for which China is a crucial market.
By choosing not to escalate tensions, China likely aims to keep open channels for potential collaboration with the U.S. on critical issues affecting both nations.
