The 3rd E class computer (Sugon) has passed milestone of key tech research and to begin the next phase of "prototype to final product" development.

  • The event happened on June 1st.
  • The architecture is X86 base CPU + GPU. All of them domestically produced. I suspect it is the licenese from AMD purchased not long ago.
  • It has a Torus 6D interconnect.
  • The chips are 7nm based fabrication.
  • The prototyping has already been finished. The meeting is the "certification meeting".
  • It is not reported by any news outlet like the other two (Shenwei and Tianhe). Why? However the project's starting was publicly announced by Sugon in 2016.

can China produced 7 nm?? as far as I know SMIC still works with 28 nm, and will do 14 nm next year

The news is only about the Sugon (曙光, Shuguang) E class. Only Sugon system is X86 based.

Tianhe is FT-2000plus CPU is ARM based.

P.S. Shenwei (申威) CPU (Taihu light) is RISC based.

I could not find news of certifications of Shenwei (神威) or Tianhe except the news of prototypes being built or completed. It does not necessarily mean anything which events are reported. But I guess, the certification of the prototyping phase should only happen after the prototype has been run and tested for couple of months and prove to reach design goals. This means that Sugon prototype is months ahead of Shenwei and Tianhe whose certification may happen some time from now to end of 2018, let's say September or October?

The original texts referring 7 nm is
考虑在7nm工艺条件限制下，DCU性能如何进一步提升，控制技术和工艺风险

Translation
Considering the limitation/constraint of 7nm production condition, how to further improve DCU performance, control technical and production risk. 工艺 (IMO) can be translated as the fabrication method.

The report is not saying that China possess 7nm production capability today. But the final product of the Chip is planned to be based on 7nm in 2020 and whoever chip maker able to do so by then.

Now I noticed Jura's post #4409 which according to the Chinese version

is that Tianhe prototype has achieved
  1. Deployment
  2. Successful subsystem certification.

So yes, we now have two certifications except Shenwei. But will be in a month. I think Tianhe prototype was about a month ahead of Shenwei in construction.

Yes, both the Tianhe and X86-based Exa-Computer prototypes have been reported to have achieved certification. It would be quite a milestone when Shenwei join the club.

recently people talked 'imminent war with Taiwan' though, in a thread which has been deleted by Mods (I reported it immediately once I saw it)

It must be TSMC. I assume all Chinese supercomputing chips are contracted to them because there is never any official mention of where they are produced. And only TSMC has a reliable 7nm process.
