Possibly. Or they've not filled all channels. I'd guess it's the latter due to very high DRAM prices for the last year or two. Time for DRAM prices to return to normal!
This beast is going to need all the bandwidth it can get, especially for HPC. Not filling all channels is not an option. I guess they'd rather upgrade memory later, if needed.
It's not uncommon for HPC to deploy incomplete. Throwing away a huge load of DRAM a year later isn't smart thinking unless they got it for a massive discount.
Sure, throwing away would be stupid. I was thinking about 2 DIMMS per channel for the extension. That would drop the frequency a bit, but that's far less harmful than unpopulated channels.
2.35ghz seems like it's a pretty good target number for AMD to have hit. A lot of people were thinking they might be sub 2ghz given the step up to 64 cores and the shiny new chiplet architecture.
Total cost for this supercomputer is 38million euros (43million dollars) https://www.hlrs.de/whats-new/news/detail-view/201... Could the 10k cpus cost about 10-15million? That would be only $1000-$1500 for each Rome, sounds extremely cheap.

Unfortunately, the wish for cheaper RAM seems likely not to materialize in the near future -- Samsung has already announced officially that they are cutting production to keep prices up and no one outside china has even plans for a new FAB. I have deferred purchases of new systems for almost an year now do to RAM costs
I, by no means, am an expert, but I assume the new chiplet design with separate I/O chip must be pretty good to end up in a supercomputer. It's interesting to see how AMD is slowly gaining a foothold in server space, again.
I would not assume that is all that the processor is capable of. More likely, that is the base clock. That said, this system may be running fix frequency so as create consistent power draw and thermals. This prevents them from over spending (money and/or space) on power distribution and cooling.

2.4TFLOPS per CPU would exactly fit the given clock speed and AMDs AVX implementation. No GPUs needed to boost that number.Only 64 GiB per CPU is interesting, looks like the minimal setup with one 8GiB DIMM for each memory channel was enough for them.

It's nerf'd for the moment anyway. It'll run good enough on caching with that little in total.tygrus - Tuesday, November 13, 2018 - link
Maybe its 16 single-precision FP ops per core per clock cycle (2x256b AVX ops per cycle)?IntelUser2000 - Tuesday, November 13, 2018 - link
No, Zen 2 architecture has 2 256-bit width vector units capable of FMA.2 x 4 DP Flops/cycle x 2 FMA = 16

I believe that is the cost for a 5,000-node cluster. So ~$3000 per RomeBoxie - Tuesday, November 13, 2018 - link

But can it play Crysis?warumich - Wednesday, November 14, 2018 - link
With huge explosions, it maxes out the 64 000 CPU cores, but overall, i would call it playable.schujj07 - Wednesday, November 14, 2018 - link
At 2.4 TeraFLOPS per CPU that works out to 37.5 GigaFLOPS per core at 2.35GHz. How does that compare to Zen+ or Coffee Lake?efferz - Wednesday, November 14, 2018 - link
I remember that the FMA instructions provide 2x fp performance，so it should be 4.8TFlops per CPUDeepLearner - Wednesday, November 14, 2018 - link
That's a disappointing frequency increase, even with the extra cores.EasyListening - Thursday, November 15, 2018 - link
