Tik tok, the clock is ticking… Only 10 more days left to submit your talk proposal for the #HPC, Big Data, and Data Science devroom at #FOSDEM’26 ! hpc-bigdata-fosdem26.github.io Same goes for pretty much all of the other devrooms BTW… See fosdem.org/2026/schedul...

Just want to emphasize here that this is an image of an INTERSTELLAR COMET taken by a camera orbiting MARS. Space is so cool!

Great interview of Ian Buck on NVIDIA's vision on the future of HPC. Few important messages: "AI is a tool, one of many tools to be able to do scientific discovery" "FP64 is a requirement" "It has to be great at simulation; it has to be great at AI; and it also has to be a quantum supercomputer"

By annual tradition, the HPC, Big Data, and Data Science devroom will be part of FOSDEM again next year (Sat-Sun 31 Jan + 1 Feb 2026 in Brussels). \o/ Please help us spread the word, and/or submit a talk proposal by 1 Dec 2025. All details available via hpc-bigdata-fosdem26.github.io 🍻

Deadline for submissions for the 11th #hpc, #bigdata, and #datascience devroom at #fosdem26 (Brussels, Sat-Sun 31 Jan + 1 Feb 2026) is Mon 1 Dec 2025. Please see details at the link below. Looking forward to another dynamic, exciting, packed session! https://hpc-bigdata-fosdem26.github.io/

Mathematician Karl Weierstrass was born #OTD, Halloween, in 1815. 🧪 🎃 The fools at The Academy all said he was mad, but he showed them all in 1872 when he announced that he had created a MONSTER. Let's learn about the terrible thing he did. Image: Smithsonian Institution Libraries

💥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! github.com/spack/spack/...

I worked at the Living Computer Museum from 2014 until it closed due to Covid (and then never reopened because Paul Allen did a shitty job with his estate planning.) It's been a bit over 5 years since the museum closed to the public and I thought I'd share some pictures I took around that time.

BlueSky: Attack of the Clones The one with Jango Fett was more entertaining!

Today we released the latest version of #Wi4MPI that includes major changes, in particular in the internals of the library. It doesn't change much for the users but it has a huge impact on the flexibility, versatility and robustness of the library. github.com/cea-hpc/wi4mpi #HPC #MPI

EasyBuild now has a blog! blog.easybuild.io First post is a report on the 10th EasyBuild User Meeting (EUM'25) -> blog.easybuild.io/2025/03/28/e... #HPC

If you are interested in running #HPC apps in cloud with #Kubernetes "Trends for Pulling HPC Containers in Cloud" - a look at the ecosystem since 2014 and a robust pulling study - is published this week at Cloud Computing 2025. It is work driven by my love and curiosity of container technologies. ❤️

Kicking off day two of the 10th EasyBuild User Meeting at Jülich Supercomputing Centre (JSC) with a keynote by Jeff Hammond (NVIDIA) Live stream via www.youtube.com/watch?v=2-4p... Slides will be made available via easybuild.io/eum25/#program @fzj-jsc.bsky.social #HPC

Very nice to see French #QuantumComputing companies (Pasqal and Alice & Bob) on stage at #GTC25, we do indeed have a very exciting quantum ecosystem here! And if you're an EU researcher, a Pasqal QPU will soon be available at @cea.fr TGCC!

That's big news for France as the AI2F consortium is one of the #AIFactories selected. It strengthens the AI dimension of Alice Recoque, the EuroHPC exascale system deployed in France at @cea.fr, and it will help to foster & support an already very lively AI ecosystem in France #HPC #AI #Europe

The recorded video of our talk at FOSDEM25 is available: fosdem.org/2025/schedul... Many thanks again to @marcjoos.bsky.social who did an excellent job presenting the talk and answering questions.

I wrote a little text to accompany this slide. It sums up the hour-long presentation in just a few words. www.glennklockwood.com/garden/diffe... #HPC #AI

If you actively use or contribute to EasyBuild, please participate in the 8th EasyBuild User Survey: ugent.qualtrics.com/jfe/form/SV_... Help us reach our goal of at least 100 participants by the end of the month! #HPC

ClusterShell 1.9.3 is now available in EPEL and Debian. Not using clustershell groups on your #HPC cluster yet?! Check out the new bash completion feature! Demo recorded on Sherlock at @stanford-rc.bsky.social with ~1,900 compute nodes and many group sources! asciinema.org/a/699526

Lmod is getting a shoutout during the talk on Environment Modules (@envmodules.bsky.social) at the 10th #HPC, Big Data, and Data Science. There’s no rivalry between “competing” FOSS projects at #FOSDEM, only mutual respect and exchange of ideas!

We are accepting mini-donations for HPC.social in the 10th #HPC, Big Data, and Data Science devroom at #FOSDEM25. I’ll pool these together and donate it all in one go right after FOSDEM, pinky swear! You can also donate directly yourself, see github.com/sponsors/hpc...

EESSI will be featured in two back-to-back talks today at 12:30 in the #HPC devroom at #FOSDEM25. Thomas Röblitz (UBergen) will talk about RSM on top of EESSI, Henrik Nortamo (CSC.fi) presenting the EuroHPC Federation Platform, in which EESSI will be integrated. fosdem.org/2025/schedul...

sshproxy presentation by Cyril Servant from @cea.fr is starting now!

Great ongoing talk by Laura Durieux at #FOSDEM on women in the early age of computer science

I'm very excited to announce that I'll be speaking at #FOSDEM this year to talk about @envmodules.bsky.social in the #HPC devroom, on behalf of Xavier Delaruelle, #EnvModules lead developer. If you want to know more about the tool and its current & future evolution, join us on Sunday at 11:05!

Remember when scientists optimized the performance of computational simulations? Sometimes those optimizations achieved big performance gains. Recall when people then bought smaller #supercomputers as a result? No. They just went on to do more science. #HPC #AI #DeepSeekR1

Some of my thoughts on OpenAI's o3 and the ARC-AGI benchmark aiguide.substack.com/p/did-openai...

SemiAnalysis after testing MI300X: “When comparing Nvidia’s GPUs to AMD’s #MI300X, we found that the potential on paper advantage of the MI300X was not realized due to a lack within AMD public release software stack and the lack of testing from AMD” semianalysis.com/2024/12/22/m... #AI #GPU

So in 2024 Spotify stopped paying artists who didn't stream enough, now we learn that they are silently injecting stock music within their playlists to increase their margins -- and to artists detriment harpers.org/archive/2025...

Environment Modules is now on Bluesky 🎉. Modules (with its `module` command) helps HPC folks managing their shell environment since more than 3 decades. This account will share news of the project.

The federation platform for the EuroHPC ecosystem is on its way! #HPC #Europe #EuroHPC eurohpc-ju.europa.eu/paving-way-e...

🤝 A consortium led by CSC will deliver and operate a federation platform for @eurohpc-ju.bsky.social. The total budget of the platform delivery is EUR 20 million. The delivery will start at the beginning of 2025 and will last for five years. Read more 🔗 csc.fi/en/news/csc-... #HPC #QuantumComputing

Woohoo! Decisions have been made on the @fosdem.bsky.social'25 HPC, Big Data & Data Science DevRoom talks and the schedule is beginning to populate at fosdem.org/2025/schedul... for what will eventually be a full day of talks in Brussels Sunday 2 February 2025 with recording and streaming available.

We are pleased to announce an #IEEE Computing in Science and Engineering (CiSE) Special Issue on Converged Computing! ☁️ www.computer.org/csdl/magazin... Discussion of the best of both worlds, #cloud and #HPC, on the level of technology and culture, is of utmost importance.

HPC devroom is on Sunday this year, so 2nd day in 2025 !

Maybe the coolest tech conference and so many great talks to hear, it's easy to get lost (600+ talks in 2 days!). But thankfully there's the HPC devroom, so it's a no-brainer for the first day on what to follow.

Call for proposals for the HPC, Big Data, and Data Science devroom at the #FOSDEM’25 open source “conference” taking place in Brussels during the weekend of 1-2 Feb 2025 is still open! hpc-bigdata-fosdem25.github.io Submission deadline Sunday 1 Dec 2024. #HPC community: help us spread the word!

#hwloc, the #opensource software created by Inria and the University of Bordeaux is used by several #HPC sites Its designers, Brice Goglin and Samuel Thibault, have just received the Inria - French Academy of Sciences - Dassault Systèmes Innovation Prize www.inria.fr/en/brice-gog...

64th #Top500 is out! o #ElCapitan at LLNL is the new #1 o We now have 3 #Exascale systems officially o #HPC6 at Eni is new at #5 o Tuolumne, a smaller version of #ElCapitan, rounds up the #Top10 top500.org/news/el-capi... #HPC #AI #SC24

#newintro with the current exodus: I'm working in #HPC, helping people using big computers; I'm interested in runtimes, containers, HPC/AI and #quantum. I maintain #Wi4MPI. I'm a trained physicist so I obviously love #Fortran. I cook, drink coffee & beer, and play & listen to loud music.

I feel seen

Really happy to see the huge inflow of people around here, especially the #HPC crowd. I gave up on Twitter about a year ago, I really like Mastodon (as clunky as it might be) but it was quieter than Twitter. I'm glad to see the #HPC community building up again (even if I'm mostly watching quietly 😶‍🌫️)

Eric Schmidt says we’re not going to meet our climate targets, so we must put all our energy into improving AI and hope it solves the problem for us. He’s part of a growing chorus of tech billionaires openly admitting they’ll sacrifice the climate on the altar of their AI ambitions.

Enrico Fermi, one of the foremost physicists of the 20th century, was born #OTD in 1901. While most physicists focus on either experiment or theory, Fermi excelled at both. Now, estimate how many new physicists will be born today. 🧪 Image: New York Public Library

Lesser known: Before NASA and Apollo, Margaret Hamilton worked with mathematician and meteorologist Edward Lorenz. From 1959-1961 she programmed weather simulations on his LGP-30 computer. Those projects were the precursors to his famous 1963 paper that marked the birth of chaos theory. 🧪 👩‍🔬 🔭

For the first time, a phenomenon astronomers have long hoped to directly image has been captured by #NASAWebb’s Near-Infrared Camera. In this stunning image of the Serpens Nebula, the discovery lies in the upper left of this image—a young, nearby star-forming region. (1/7) 🔭 🧪 🧵
