Oct 7 (Reuters) – Deciding who will get harm by sweeping new U.S. curbs on promoting expertise to China will come down partially to what constitutes a “supercomputer,” specialists informed Reuters.
All over the world, the semiconductor business on Friday started to wrestle with wide-ranging U.S. restrictions on promoting chips and chip manufacturing tools to China.
Shares of chip tools makers drooped, however business specialists mentioned a brand new U.S. definition of a supercomputer might be pivotal to the brand new guidelines’ influence on China.

Supercomputers can be utilized in creating nuclear weapons and different army applied sciences, and specialists say methods to outline them has lengthy bedeviled regulators making an attempt to pin down an ever-advancing technological goal.
The brand new American guidelines outline supercomputers broadly by way of computing energy in an outlined area: a machine with 100 petaflops – the flexibility to hold out 100 trillion operations per second – in 41,600 cubic toes, with another caveats.
Senior authorities officers mentioned in a media briefing that their intention was to focus on solely China’s most superior techniques that might characterize a nationwide safety risk to america fairly than industrial exercise.
However specialists puzzled whether or not Chinese language tech giants’ densely packed knowledge facilities owned by the likes of Alibaba Group Holding (9988.HK) or TikTok-owner ByteDance would possibly quickly attain supercomputer standing based mostly on the brand new definition, even when that’s not what U.S. regulators supposed.
“Information heart build-outs like Alibaba or ByteDance would have the potential to succeed in petaflop build-outs,” mentioned CCS Perception chip analyst Wayne Lam mentioned.
The brand new definition is unlikely to vary as business expertise improves. Present-day Chinese language supercomputers could someday turn out to be the company normal, however they may nonetheless face the bounds imposed Friday to cease any chip made with U.S. tools or expertise from going into China. Corporations “could very effectively run into supercomputing limitations throughout the subsequent couple of years,” Lam mentioned.
Jack Dongarra, a professor of pc science who helps lead a gaggle referred to as TOP500 that ranks the world’s quickest supercomputers, mentioned he disagreed with the static definition.
“The difficulty is that the definition of a supercomputer will change over time,” he mentioned by e-mail.
Main Chinese language corporations with huge knowledge facilities similar to Baidu, Alibaba and ByteDance didn’t instantly reply to requests for remark. Tencent declined to remark.
The definition of computing energy per cubic foot additionally could supply room for inventive workarounds. For example, mentioned one knowledgeable, use fiber optic cables to tie collectively immense computing energy over a bigger area.
“They might unfold their supercomputers out over a bigger area,” mentioned one chip and knowledge heart knowledgeable who requested anonymity because of the politically charged nature of the brand new guidelines.
“The typical supercomputer architect would say, ‘That is not how issues are finished!’ However not with the ability to do it one other means breeds numerous creativity, and willingness to do issues otherwise.”
