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!

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

That's the highest among all of big tech.

How do we build machines that can see? In a talk at @Livermore_Lab, @Stanford professor and #AI visionary Fei-Fei Li traced a sweeping arc in visual intelligence and AI — a narrative she hopes ultimately leads to a more human-centered future. https://t.co/UZLsI0bVxg

The ETH Zurich team @ETHRacklette has gone full "psychotic mode" with a flatlined 6000W run of HPCG. Competition limit is 6k...1 watt more and it's "uh oh" time. 😱#ISC25_SCC #ISC25 https://t.co/vXgl3sD09J

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).

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

"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.

HPL-MxP:

1. El Capitan with 16.7 Exaflop/s

2. Aurora with an 11.6 Exaflop/s

3. Frontier with 11.4 Exaflop/s

Congratulations to #ElCapitan @Livermore_Lab for taking the top position in all 3: Top500, HPCG, and HPL-MxP

Major news from the #Top500 at #ISC25. The top systems are getting more balanced! All top three HPL systems score very high in categories of mixed precision and HPCG (memory performance). Ready for #AI and #HPC!

[Satoshi Matsuoka @ProfMatsuoka]

At ISC25. Just received our # 1 in Asia for the Top500 (7th overall) and # 2 for HPCG. We continue to be # 1 for the Graph500. A supercomputer being 5 years old still being one of the top machines in the world. https://t.co/tFQhXOYMh7. We got more systems coming next year.
