@tnorris.bsky.social on why narratives about data center power demand are making it appear more constant & closer to full capacity than it actually is. Getting this right is key to heading off overbuild of generation and grid infrastructure. Big implications for climate, electricity rates and more.
The Puzzle of Low Data Center Utilization Rates
Contrary to popular belief, data centers aren't maxed out around the clock - and this has real consequences for power system planning

Looks like the course material is also all open. Good examples to show how all the pieces can fit together in practice: gitlab.tuwien.ac.at/vsc-public/t...

Cant wait to try this out. Huge achievement!

💥Spack v1.0 is out!💥

This is a huge milestone. We reworked the core to add compiler dependencies, and we're introducing a stable package API.

🚀1.0 also adds concurrent builds, better includes, and much more -- read it all in the release notes!

Are GitHub stars something of a silly metric?
In my opinion, "yes."

Would I like you to star our project anyway?
Also "yes". :)

We recently received our 1,900th star on GitHub! Thanks to all who’ve shown their support for the Chapel programming language in this way and for helping to grow awareness of our open-source community.

Haven’t starred us yet? Help us reach 2k at: github.com/chapel-lang/...

The good people at @vastdata.bsky.social were kind enough to post an announcement (and Q&A about #AI) about me joining the company. Nothing too deep, but a peek at whats to come! www.vastdata.com/blog

Shorter summary: Everybody wants GPU access and computer scientists are trying to shame academic institutions into buying more. https://arxiv.org/abs/2506.19019

To my mind it’s a positive feature and not a bug that we have programs like https://nairrpilot.org/ to soak this interest up. Scaling […]

At the panel on energy efficiency beyond hardware, the topic of “why can’t we do what cell phones do?” came up. Amazed that #HPC people don’t understand that the latency requirements of a human-driven device are way easier than RDMA and memcpy.

Latest #Top500 should be available soon.
Top500 website being updated messafe.
Found the “Welcome Tour” on Switch 2 a great way of introducing the system and goes into a lot of detail. I especially like the hidden tips like ways to get completion if you dont have an accessory or option. Now to make one for Supercomputers. #switch2
Son found the joy of new console. Download of 2 hours for included Mario Kart World and took about an hour to fully unbox and setup (inc. transfer). Welcome Tour was easy to obtain. I did offer to preconfigure but he wanted to do it. Does look good, still to try more of the upgraded games. #switch2

I'm looking forward to my last talk "ARMing GPUs: On the Memory Subsystem of Grace Hopper GH200" at #SCAsia2025 at the ARM for #HPC workshop tomorrow.

Learn about the quite complex and powerful memory performance at 4:15pm in room O7 🚀

How does a parallel programming language like Chapel utilize GPUs? On March 12th at 9AM PT, join Engin Kayraklioglu as he walks through some of the implementation details in a live demo session. #HPC #OpenSource
