Lessons learned from three years in cloud supercomputing I recently decided to leave Microsoft after having spent just over three years there, first as a storage product manager, then as a compute ...

In the few days I have between jobs, I wanted to share an unvarnished perspective on what I've learned after spending three years working on supercomputing in the cloud. It's hastily written and lightly edited, but I hope others find it interesting: blog.glennklockwood.com/2025/07/less...

Thanks for sharing this and curious about where you are heading to - hope you‘ll still stay in the #HPC community. Wherever you are going next, they are lucky!

The bootcamps are over for now, but we'll continue our collaboration with #NVIDIA and #OpenACC_org for the AI Hackathon - for teams of 3+ & AI project - application deadline is 5 August

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…

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 💯

Big resource providers should make the production emission part of the procurement! #Sustainability must be a key element from now on! @cflorina.bsky.social @unibas.ch #CarbonNeutral #HPC #pasc25

Cynical mode: “sovereign” was a clever way to make each nation buy its own cloud/ai infra instead of using others.

Visionary: sovereign makes each nation think “what if” & ensure it controls its own data.

Provocative: nations don’t own data anyway - companies (often multinational) or people do.

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
