Does anyone know more about the Chinese "Sunway" chips used in the TaihuLight? The wikipedia description sounds really interesting, sort of like the old Transputer.

Here's a pretty detailed write-up: http://www.netlib.org/utk/people/JackDongarra/PAPERS/sunway-...


It looks difficult to code for (although the paper mentions they have their own parallelizing compiler & have successfully compiled several real applications).


3.0624 Tflop/s per node - that is impressive. And then you can fix 1024 nodes per cabinet for a peak rating of >3 Pflop/s per cabinet.


Apparently it's based off the DEC Alpha. A lot of the important documentation is written in Mandarin, do bear in mind.

I've also heard rumors that utilization on real world workloads is very bad. (Not necessarily agreeing, just relaying hearsay).
