The point is this. The Chinese built an Exascale Supercomputer with 14nm chips, which SMIC in China can probably make already or very soon, entirely using domestic inputs.

This supercomputer was never reported to the semi-annual list of the Top500, the Chinese decided to not say much about it. The rumour was that the Chinese was building the fastest supercomputer, but wanted to keep it a secret due to the trade war and tech war launched by President Trump.

Officially, the fastest supercomputer is from Japan the Fugaku at 442 petaFLOPS per second.

The unofficial Chinese supercomputer that is not suppose to exist, but it does, is measured performance in exaFLOPS which is a magnitude faster than anything that exists today. China has two of these machines going around 1 or 2 exaFLOPS per second.

One quote from the article, to summarize the contest of supercomputing:

If the 160 cabinet scale is the maximum for OceanLight, then China could best the performance of the 1.5 exaflops “Frontier” supercomputer being tuned up at Oak Ridge National Laboratories today and also extend beyond the peak theoretical performance of the 2 exaflops “Aurora” supercomputer coming to Argonne National Laboratory later this year – and maybe even further than the “El Capitan” supercomputer going into Lawrence Livermore National Laboratory in 2023 and expected to be around 2.2 exaflops to 2.3 exaflops according to the scuttlebutt.

The United States will have an exascale supercomputer soon in 2022 or 2023 which may be as fast as the Chinese machines.
