All things, with one exception, have to end After years of sharing #HPC news and insights, it's time to log off It was fun while it lasted and I remain grateful to all of you who followed and interacted Stay curious, stay kind! — @hpcguru.bsky.social signing off #HPC #Farewell

Nvidia now generates roughly $4 million in revenue for each employee they have That's the highest among all of big tech #HPC #AI #GPU

ISC 2025 HPSF Community Birds of a Feather (BoF) + marking one year since launch at last year's ISC 🔥 with panelists: 💠 Julien Bigot, CEA 💠 Christian Trott, Sandia National Laboratories 💠 Heidi Poxon, NVIDIA 💠 Todd Gamblin, LLNL 💠 Andy Warner, HPE #HPSF #HPC #HighPerformanceSoftware #ISC25

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:

40 years of #ISC – 3 in 1 panel nicely moderated by @addisonsnell to provide a good grasp about the past, present, and future of #ISC

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).

The new #TOP500 & #Green500 lists are out: 🔹#EXA_JUPITER is now Europe’s fastest supercomputer, ranked #4 worldwide 🔹LUMI & Leonardo continue to lead in the global top 10. More details on the rankings of #EuroHPC supercomputers: europa.eu/!pc3bjQ

The new edition of #top500 is out! 🇺🇸 El Capitan remains the most powerful system in the world 🇩🇪 JUPITER is now Europe’s fastest #supercomputer 🇫🇮 LUMI & 🇮🇹 LEONARDO stay in the global top 10 top500.org/lists/top500... #hpc image by @eurohpc-ju.bsky.social

❄️ @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. 🔗 Read more: csc.fi/en/media-rel...

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.

JUPITER supercomputer, powered by the NVIDIA Grace Hopper platform, is the fastest in Europe — delivering a more than 2x speedup for #HPC and #AI workloads compared with the next-fastest system nvidianews.nvidia.com/news/nvidia-... #ISC25

LRZ’s #BlueLion #supercomputer will be based on Nvidia’s Vera Rubin architecture It’s the second large system based on Vera Rubin, following NERSC’s Doudna blogs.nvidia.com/blog/blue-li... #HPC #AI #ISC25 #GPU

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. #ISC25

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

HPL-MxP: 1. El Capitan with 16.7 Exaflop/s 2. Aurora with 11.6 Exaflop/s 3. Frontier with 11.4 Exaflop/s Congratulations to LLNL's #ElCapitan for taking the top position in all 3: Top500, HPCG, and HPL-MxP #ISC25 #HPC #AI via @profamandarandles.bsky.social

"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.

#HPCG: There's a new #1, after a long reign by Fugaku 1. El Capitan 2. Fugaku 3. Frontier 4. Aurora top500.org/lists/hpcg/2... #ISC25 #HPC #AI

El Capitan at LLNL sweeps the Top500, HPCG, and HPL-MxP! It’s been a while since we have seen one machine take first on all three. Congrats! #ISC2025 #hpc

Today at 11:30, our director Thomas Schulthess will present at #ISC25 "Alps” – one year on from the first GH200 rollout" in the session "HPC in Europe". Don't miss it!

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

65th #Top500 is out! 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 #HPC #AI #ISC25

Question from Horst Simon to #ISC25 keynote speakers - how many Small Modular Reactor companies will be exhibiting at ISC 2035? #HPC #supercomputers

Here at #ISC25 in Hamburg this week. I’ll be speaking about open standards at the Birds of a Feather Sessions (#OpenMP and #UXL Foundation) and sharing (alongside #NVIDIA) how to program GPUs with standard #C++. Looking forward to catching up with this great community. #HPC

Rupak Biswas and I are ready to pose our questions to eight #ISC25 sponsors: Eviden, Broadcom, VAST Data, IBM, Starfish Storage, Cornelis Networks, Samsung, HPE

As part of #ISC25 opening keynote, Mark Papermaster says @AMD will launch Instinct MI350 GPU series on Thursday, claiming achievement of goal to reach 30x improvement in energy efficiency by 2025.

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

#ISC25 is officially underway! HLRS is excited to be here in Hamburg, joining the international community to discuss the future of #HPC. Visit us at the GCS Booth K02 to explore our current research, services, and innovations in simulation, AI, and data analytics. 📅 10–13 June 2025 | 📍 CCH

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

The #isc25 conference has a strong keynote speaker lineup from around the world this week. Looking forward to hearing all three.
