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:

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
