EP 402: China Takes A 'Shine' To The Top 500 / More News And Trends From ISC2026

ago.

It sure did.

One of the major contributors here, this being such a unique system, is it's CPU only.

It was the LX2 processor, ARMv9, LingQi interconnect.

But, you know, this is a full proprietary stack.

And this is something that we've seen before, isn't it, Addison?

We have.

It really reminded me a lot of the systems that we've seen recently at RIKEN with the Fugaku supercomputer, or really even the K computer before that, where we saw these CPU-only, similar to Fugaku, it's an ARM interconnect.

Now, there was also an ARM processor, also a Custom Interconnect, which in this case appears to be using InfiniBand based silicon, but it's not an NVIDIA networking solution.

This is a Chinese deployed, Chinese designed supercomputer with Chinese technologies.

And notably, it's the first system that China has put on the top 500 list in the last seven years since it had successive number one systems, first with the Tianhe 1A system, followed by the Sunway Taihu Lite system.

They hadn't put a new number one system on the list since the last time Sunway Taihu Lite debuted at number one.

Something you've said before that I repeat all over is it's not surprising that China has this system, right? It's surprising or interesting, maybe, that they decided to put it on the top 500.

In my opinion, it just seems like a flex and they deserve to flex, but it certainly is a flex.

Yeah, so why list this one now, I think, points more toward why haven't they been listing them before.

Back in that era of Tianhe 1A and the Sunway Taihu Lite, there was a lot getting mixed up in some of the advanced Intel coprocessors of the time and export limitations getting placed on American technologies going to China as a result.

Now, fast forward to today.

First of all, China is showing off that they've got their own domestic technology pipeline where they can build at least a CPU based system, if not a GPU based system on their own technologies.

And furthermore, against the backdrop of tariffs and rare earths and everything else going on geopolitically, maybe one supercomputer isn't seen as, oh, this is what's going to define Sino-American relationships on a global stage at this point.

Definitely.

It's been an interesting moment to just kind of paw through the information we have on this.

It's optimized for double precision FP64.

In this AI era we're living through, it's certainly a unique choice, but it's an interesting choice for sure.

And while you can point to a few things about it that might seem stunty from a top 500 perspective, someone on our advisory committee for the HPCAI leadership organization, Halo, pointed out to me it's not as stunty as some other number one systems that we've seen.

I think we shouldn't overestimate or underestimate this line shine system.
