The Future of Storage for HPC and AI The AI arms race has made “GPU” and “gigawatt” household words, and for good reason: What’s happening with the scale of compute is unprecedented. But what about the underlying storage […]

Part 1 of the special HPCwire series about the future of #storage for #HPC and #AI lays out the current state of storage for AI and HPC and touches on some of the broad challenges that organizations are facing.

That's a lot! Maybe some papers could fit in other tracks. For HiPC, we reassigned a bunch of Apps papers (most of them to the AI/ML track).

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…

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!

I wrote up some notes on how to approach I/O and storage benchmarks in RFPs. I normally don't post here about updates to my digital garden, but I think this page is tidy and useful.

- Des podcasts légers
- De la lecture SF/fanstastique en plus grand quantité qu'habituellement
- Des sessions Magnetix/Duplo/train avec mon fils

Ça ne suffit pas mais ça atténue...

Ma femme vient de me faire commencer l'Assassin Royal (franchement, presque sous la contrainte). C'est mon premier vrai pas dans le fantastique, étant habituellement un lecteur de SF. J'ai dévoré la première partie ! C'est vraiment cool 🙂
