This week in Foundations of #LLM Mastery:

✨Fine-tuning on one GPU
✨Fine-tuning on multi GPUs

Martin and Simeon are back with their cute Llamas and great explanations:

🦙 LLM parallelization
how to chop up a Llama
🦙 LLM evaluation
how to take a Llama‘s measurement

Could not come to SC25 because I had to teach:

🎯 Parallel Programming with #MPI
🎯 One of the most iconic tools in #HPC
🎯 Don’t work hard – work in parallel 🚀

MPI processes are just like humans talking to each other – this is what Copilot gave me (back in Apr 2025) to depict MPI communication:

This week we've moved parallelism to a new level – our DL course and our OpenMP course were done in parallel – which picture is your favorite?

Next week, we'll start with the November edition of our famous LLM course series – there are still seats available!

Amazing - just 1.25 kilometres - what a fantastic achievement 👏
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…
