Observation from #ISC25: None of the Big 3 cloud service providers have booths this year. Don’t recognize any of the big GPUaaS providers either, not even the ones who debuted on Top500 today. Plenty of quantum though. What’s this say about the state of AI in Europe? And cloud HPC for that matter.

Panelist view from the full-house "ML/#AI for Workload Analysis in #HPC" BoF at #ISC25! Great talks and interaction - we went into "flipped classroom" and started asking questions to the audience. I very much enjoyed the invite from Kadida Konate (LBL) and Sergio Iserte (BSC).

At the #ISC25 vendor showdown, I think Bruno from Eviden captured a key difference between HPC and AI businesses. Paraphrasing, HPC people like to fuss with the system. AI customers don’t care about the system. Suggests why NVIDIA has been so successful. Meet the customers where they are.

If you define hyperscale to be the size of the largest #HPC datacenters, Top500 systems qualify as hyperscale. I’m not sure what the value of this proclamation is though. In real hyperscale, the qualifier is how many of these 50-200 MW sites you have, not just the fact that you have one. #ISC25

"All the systems on the #Top500 combined have about 1 GW peak power consumption today" E. Strohmeier at #ISC25. When will we see the first single datacenter with 1 GW in #AI or #HPC? Some have been announced recently 😉. Talks about SMRs heating up here.

One thing I love about ISC is that Chinese researchers are given top billing. I was surprised to see focus on applying FPGAs for reverse time migration. I’ve not heard of others leading in this field thinking about that. I also didn’t realize China cared this much about #HPC for oil & gas. #ISC25

The power wall facing #HPC seems increasingly like the Great Manure Crisis of 1984. Exascale in 20 MW turned out to be an arbitrary and false barrier. 1 GW for a zettaflop will be too. It will happen regardless of if people write PhDs on it or not. #ISC25

Papermaster’s claim that Top1 system performance doubled every 1.2 years suggests that growth in investment has been making up the difference with Moore’s Law. Suggests #HPC is a good market to go after—if you’re selling #1 systems though. And I don’t think Top1 is very directly profitable. #ISC25

Some great debate already in response to this. But are we just defending FP64 because it is what we have now and what we know? Would we defend FP32 just as hard if that is all we had? If we had pervasive FP128 would we be arguing that a drop to FP64 is not good enough? #ISC25 #HPC
