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!

It‘s the end of the semester!
It‘s excursion time!

Today I took my InterMaths students on a guided tour to finally see the hardware they were using during the labs.

What does it need for a bootcamp?

👉 Careful planning well ahead

👉 120 participants
👉 13 teaching assistants from
👉 7 #HPC centers
👉 1 great instructor from #NVIDIA
👉 2 moderators

And…

Our #GPU bootcamps reached the next level – Multi-GPU 🚀

Last week we had 120 participants in Zoom, on Slack, and on the GPUs of #Athena (Cyfronet) – it’s great to see so much interest in #HPC

Is training scalable? With the right partners and a little parallelization definitely yes! A while ago we conducted a quite large ✨AI4science✨ boocamp with 210 participants – 2 very intense half days in Zoom, on Slack, and on the GPUs of 3 HPC systems – absolutely amazing 💯

The New MPI-5.0 – Now With ABI Included! – BoF at #ISC25

A full room & a lot of interest – no wonder since #MPI is one of the most iconic tools in #HPC.

We want to hear from you what you expect from MPI-6.0!

By 2030 it will/might be possible to study how clouds react to warming and how areosols influence the climate systems

To embed climate information in decision making needs:

📍 a way for people to access this information
📍 standards that protect and valorize best practices

Big Questions for the Future of #HPC-#AI – Fishbowl panel at #ISC25

Fun and interesting – constantly looping in new panelists & new viewpoints 👀

In the end @thoefler.bsky.social managed #Connecting_the_Dots in a truly positive way.

Recommendations from the panel for women in #HPC

👉 Be yourself!

👉 Learn to be resilient!

👉 Plan your life like a job scheduler – sometimes some jobs are just more important than others, some jobs take more time than others, priorities shift over time.
