My 13yo showed me this passage in a book he was reading the other day. My response: "yeah, I've got one of those (blades) in my office". πŸ˜„

Yeah, this has been a go-to for years. Becoming especially important lately trying to find facts in the AI hype cycles.

The only office in the Twin Cities was for educational software and Office trainings, last I looked.

That would have been super valuable

The extra fun trivia is that I posted that message while sitting at the project kick-off meeting in Tokyo. :-)

To be chosen to participate in the design of the next iteration is a massive honor for us.

Through this partnership, we aim to develop a scientific discovery ecosystem based on the full integration of simulation and AI. We hope this work will benefit not only Japan, but also researchers worldwide.

RIKEN, Japan’s Leading Science Institute, Taps Fujitsu and NVIDIA for Next Flagship Supercomputer Japan is once again building a landmark high-performance computing system β€” not simply by chasing speed, but by rethinking how technology can best serve the nation’s most urgent scientific needs. At t...

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.

Those numbers were from their feasibility study and not necessarily where the design will land.

I, too, was once highlighted by DCD once on a move (to Azure).

This is a well-known Minnesota-ism, so I've been polluted from birth.

If it makes you feel better, it bugs the heck out of my wife.

Having watched engineers do the hybrid HPL run on Trinity, you should be sure to give anyone who attempts it lots of love (and a raise πŸ˜„)

There are none installed so the numbers would be the same. πŸ˜‹ Once they come, they could try to do a hybrid run, but it would be an enormous pain to do and not much upside.

If only there was a project that experimented with cell phone chips as supercomputers, where we could learn about this!

I mean, it was a decade long and even European!

Same here. I came to social media to try to teach people things once in a while. You've always been happy to amplify whomever is helping others grow.
#IamHPCGuru should be a rallying cry for giving new points of view a fair shake.

I think the best warmup for #ISC25 is a leisurely stroll through the botanical gardens across the plaza from CCH.

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(!)
