Amazing - just 1.25 kilometres - what a fantastic achievement 👏

Torsten Hoefler 🇨🇭 @thoefler.bsky.social · 11d

Cool and impactful project led by the MPI-M: coupled simulation of the full Earth system in 1.25km resolution. Unprecedented complexity, fidelity, and performance at 82.5 simulated days per day. Accelerated by DaCe on GH200 - next generation #HPC for #climate science is here!

Global climate simulations achieve 1.25 km resolution—team nominated for Climate Gordon Bell Prize | CSCS

For the first time, scientists have run global coupled climate simulations at a resolution of just 1.25 kilometres. Using CSCS’s “Alps” supercomputer, the team including researchers from ETH Zürich…

Actually that‘s why we all build some tiny 4-8 node RPi clusters - to display them at events, to get people interested, to explain concepts. One can even learn something when designing and building these RPi clusters & have lots of fun.

Lego clusters seem to get en vogue too, we‘ll have one soon.

Surprised that over half of the NERSC workload stands to benefit from quantum computing, but this report explains it well. Can now see that there's more than marketing behind #HPC centers ramping up investment in quantum.

Quantum has huge potential impact in scientific domains over the next decade.

- expands and enhances your prompts
- delivers transparent and up-to-date answers
- reduces hallucinations
