Is it the first to reach 2 exaflops?

Extremely impressive accomplishment considering they did this with Chinese interconnects and Chinese chips. This is a wake up call.

Would the AI “GW-scale” clusters be able to run the Top500 benchmarks meaningfully? And what might be the outcome?

> Why aren’t these AI companies submitting to the TOP500 to show off their computing prowess?

my knowledge is 10+ years out of date, but once upon a time if they'd chosen to, Google could have had _several_ entries in the top 10 of the TOP500 list

It's just poker, they didn't want to tip their hand

Just glad to see Hamburg mentioned :) Hope you all didn’t suffer too much through the current heatwave

TOP500 hasn't been a particularly useful measure of practical computing power in modern systems for many years because what it measures isn't a significant bottleneck in most real systems. It has become a measure of how much money someone is willing to spend for bragging rights. (HPCG is better in that it is a bit more bandwidth focused but still pretty narrow.)

Most companies with huge systems don't participate.

> Two cores are disabled per cluster.

I’m sure there is a good reason for this, which is..?

> We think it is highly likely that these LX2 chiplets are etched using SMIC 7 nanometer processes at the N+3 refinement, and we base that on the fact that the chip only runs at 1.55 GHz. That is nowhere near the 3 GHz that SMIC can push with that process, but it is probably lower to get the memory and core speeds more balanced. [1]

Based on the ARMv9.2.
