I wrote up my notes from #SC25. Have a look: blog.glennklockwood.com/2025/12/sc25...
I’ll keep picking away at the editing, but would love to hear more from others about what stood out to them. I wasn’t at the conference itself as much this years as in the past, so I know I missed a lot.

Those who have been around #HPC a while know the historical significance (and probably the names) of Japan's flagship supercomputers. They always push the boundaries of technology, but in ways that are driven uniquely by the needs of Japan.

This is a great article that explains the philosophical innovations behind NERSC’s new supercomputer: science is not just about batch jobs anymore. Draw the good ideas from AI infra advances into #HPC as possible. Definitely worth reading.
Also, they’re using GPFS instead of Lustre(!)

20 minutes into a talk by Ian Buck and his focus has been almost exclusively scientific computing. Little/no mention of AI, in sharp contrast to Jensen’s keynote. Surprising.
