Nvidia now generates roughly $4 million in revenue for each employee they have

That's the highest among all of big tech

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.

Dynamic Use of Resources for Affordable Exascale and Beyond – BoF at #ISC25

Take aways for our sysadmin team – we need (rather sooner than later):

👉 Monitoring
👉 Al-Based Data Analytics
👉 Dynamic Scheduling & Resource Mgmt

We‘ll definitely need to break some long standing dogmas as Martin says:

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).

❄️ @lumi-supercomputer.eu ranks 9th on the new Top500 list! Over 3,000 scientific projects have already run on LUMI.

✨ Next up: LUMI will be succeeded by an AI-optimised supercomputer called LUMI-AI, as part of one of the EU's first AI Factories.

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.

Though not the intent of this slide, Erich pointed out that a bunch of GPUaaS/neocloud providers (Nebius, Core42, etc) are now submitting HPL numbers. These systems are still modest in size, but if the bigger ones like CoreWeave ever jumped aboard, the significance of Top500 might skew.

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.

"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.

o The Top 3 #Exascale systems remain unchanged:

#1 El Capitan
#2 Frontier
#3 Aurora

o JUPITER Booster (EuroHPC planned #Exascale system currently being commissioned – hence partial system) at FZH in Germany at #4 is the only new system in the #Top10
