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

@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.

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...

C++ std::simd (ok, std::datapar) is cool. Portable, order-of-magnitude speedups (w/ modern CPUs and the right, flop intense algorithms) 🚀 #HPC #SIMD

AIRR advanced supercomputers for the UK

After the official switch on of Isambard-AI last week, you can now apply for time on this amazing resource! Open for researchers and companies in the UK, find out how to apply to the UK's newest and fastest supercomputer at the following link: www.gov.uk/government/p...

Cant wait to try this out. Huge achievement!

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

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

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.

UK's Isambard-AI super powers up as government goes AI crazy Brace yourselves Britain, PM Keir Starmer's challenged his teams: 'show me how they can use AI' Britain's beefiest supercomputer, Isambard-AI, is set to become fully operational this summer, as the government steps up its strategy to push AI everywhere as a driver for economic recovery.…

UK's Isambard-AI super powers up as government goes AI crazy

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

Brit universities told to keep up the world-class research with less cash Government boasts of £14B in R&D spending, but grant body takes £300M hit Despite ambitions to position itself as a science and tech superpower, the UK has cut the budget for the government body responsible for university research funding.…

Nvidia’s AI suite may get a whole lot pricier, thanks to Jensen’s GPU math mistake The old naming convention didn't just 'screw up' the NVLink nomenclature - it left money on the table Comment  At its GPU Technology Conference last month, Nvidia broke with convention by shifting its definition of what counts as a GPU.…

This is a call out to bioinformatics developers that we are working to get all of NF-Core pipelines (and by extension most of Bioconda) to support Arm.

MacOS seems to make it really hard to set default apps. For example to set default mail app you have to create an account in the apple mail app to get to the setting. Seems to be common issue after searching for solution.
