'Ten years ago, China had 21 systems on the Top500 list of the world's
largest supercomputing systems. It now has 219, according to the
biannual listing, which was updated just this week. At its current
pace of development, China may have half of the supercomputing systems
on the Top500 list by 2021.... U.S. supercomputers make up 116 of the
latest Top500 list.
Despite being well behind China in total system count, the U.S. leads
in overall performance, as measured by the High Performance Linpack
(HPL) benchmark. The HPL benchmark is used to solve linear equations.
The U.S. has about 38% of the aggregate Top500 list performance. China
is in second, at nearly 30% of the performance total. But this
performance metric has flip-flopped between China and the U.S.,
because it's heavily weighted by the largest systems. The U.S. owns
the top two spots on the latest Top500 list, thanks to two IBM
supercomputers at U.S. national laboratories. These systems, Summit
and Sierra, alone, represent 15.6% of the HPL performance measure.
Nathan Brookwood, principal analyst at Insight 64, says China is
concerned the U.S. may limit its x86 chip imports, and while China may
look to ARM, they're also investigating the RISC-V processor
Paresh Kharya, director of product marketing at Nvidia, tells Tech
Target "We expect x86 CPUs to remain dominant in the short term. But
there's growing interest in ARM for supercomputing, as evidenced by
projects in the U.S., Europe and Japan. Supercomputing centers want
choice in CPU architecture.'

Looks like such sanctions would backfire for US companies, by losing
major customers for their products.
