The future of #DeepLearning is sparse! See our overview of the field and upcoming opportunities for how to gain 10-100x performance to fuel the next #AI revolution. #HPC techniques will be key as large-scale training is #supercomputing.

Swiss universities continue to shine globally 🎓 ETH Zurich ranks 8th in the latest QS World University Rankings, remains the top university in continental Europe, and marks its 12th straight year in the global top 10. EPFL ranks 22nd. https://t.co/hHbpUcyGzS

[About Switzerland @AbtSwitzerland]

🇨🇭 Swiss universities continue to punch above their weight.

For the 12th year in a row, @ETH_en ranks among the world’s top 10 universities, placing 8th globally and remaining the highest-ranked university in continental Europe.

Swiss excellence goes beyond one institution: @EPFL ranks 22nd, while @UZH_en is 98th. Several other Swiss universities also feature in the global top 500.

At #AI4X, Michele Ceriotti questions inductive biases even in material sciences, calling "Let them learn". An interesting hypothesis also in other sciences.

I will give an overview of AI for Science in Climate Sciences, a hard one to validate.

Join us tomorrow 9am! #AI and #HPC

[Torsten Hoefler 🇨🇭 @thoefler]

Arrived at #AI4X in Singapore for Chorh Chuan Tan's opening remarks setting the stage for AI for Science as an accelerator.

"Nations not using AI in Science will likely fall behind".

SG will "converge science" with computation and AI through autonomous labs.

Jensen Huang @ Build: "Microsoft deployed the largest number of Grace Blackwells in the world today."

Kudos to the network team with MRC, a step towards UE - very large, cost-effective, and resilient deployments.

Last month, we wrapped up the ADIA Lab Summer School: Responsible AI in the Generative and Agentic AI Era, delivered in collaboration with the University of Granada.​

The programme brought together 49 students from 15 countries, to explore the technical foundations, governance challenges, and real-world applications shaping generative and agentic AI today.

In individuals, insanity is rare; but in groups, parties, nations and epochs, it is the rule.

[adia_lab @adia_lab]

During this year’s ADIA Lab International Summer School in Granada, several of our cohorts presented their group projects through a series of poster sessions based on this year’s theme, Responsible AI in the Generative and Agentic AI Era.

Stay tuned for more highlights from the summer school, held in collaboration with the University of Granada.

@Dlt_hpc You were able to sign up online (check the blog posts) but I don't know about the timeline.

[Torsten Hoefler 🇨🇭 @thoefler]

Big announcements on MS Build: Maia 200 online in Iowa and Arizona, going international soon at 30% better TCO than best GPUs! Big success for our SDLA architecture. 🚀

Running GPT-5.5 and MAI's thinking model at 1.4x perf/W vs. GB200 👏

After a nice early morning run, #SciFM26 in Chicago continues.

Rafael shows how many physics models learn the same representations in their latent space if you compare proximity of embeddings.

Next: my panel on the disappointment of physical biases and priors in climate models.

[SPCL@ETH @spcl_eth]

📢 Today at IPDPS 2026, Tommaso Bonato will present "Spritz: Path-Aware Load Balancing in Low-Diameter Networks."
📍 1:30 PM CDT, Salon D.
👋 Come say hi if you're around!

Just arrived at SciFM in Chigago. First thing I hear from the panel is great: "Agents are the new programming. They form their own language and system stack. And we computer scientists should contribute the algorithms."

💯, we also need to develop the best architectures! #HPC

[HPCwire @HPCwire]

The #SciFM26 conference begins today in Chicago. Check out this preview about the event from HPCwire Managing Editor Alex Woodie: https://t.co/N0fkLwwv6o

@ProfMatsuoka @JamesLinHPC I don't think Yutong said it - we can ask her at ISC.

[Torsten Hoefler 🇨🇭 @thoefler]

Yutong Lu reveals the LineShine exascale architecture for #HPC - #AI convergence: 2 exaflop sustained fp64 at 40 MW with 1.34 million ARM CPUs using SME and 4TB/s HBM connected with 800G.

From "offline to online acceleration with SME".

[Torsten Hoefler 🇨🇭 @thoefler]

@StanTechAddict Cores, true! 44k CPUs.

[Torsten Hoefler 🇨🇭 @thoefler]

Mateo Valero discusses history of vector architectures: Back to the Future in #HPC and #AI.

He also mentions the three quantum computers connected to an NVIDIA Blackwell system in BSC's chapel ⛪️.

Ending his talk looking for a future site 😀.
