Spack v1.1.1 is out! This is a patch release with some notable improvements: * Python 3.14 support * Better error messages for missing/deprecated versions * Major performance improvements for the solver Read it all in the release notes! #hpc #spack github.com/spack/spack/...

The best part about organizing the #HPC devroom at #FOSDEM is that I don't need to wade through half of the schedule, since I already know where I'll be spending my time. Really helpful, since FOSDEM'26 has over 1,000 talks in a single weekend! 😱 😎 🤩 fosdem.org/2026/schedule/ #FOSS #community

Schedule for #HPC, Big Data, and Data Science devroom at FOSDEM'26 (on Sun 1 Feb 2026, in Brussels) has been published: fosdem.org/2026/schedul...

This is an absolutely spectacular agenda. Congratulations to @boegel.bsky.social for once again putting together a great #FOSDEM devroom for those interested in #HPC, #BigData, and #DataScience and organizing the reviews.

It’s safe to assume that the HPC scheduling space is going to be in a state of Flux for quite some time to come… (I see what I did there. With consummate apologies to @vsoch.bsky.social and @tgamblin.bsky.social in advance 🤣)

"With HPSF, the #HPC community now has what I consider to be the largest and healthiest forum for developing and nurturing open source software that it ever has," says @bradcray.bsky.social in Chapel blog: chapel-lang.org/blog/posts/1...

The CFP for HPSFCon 2026 is open 🤩 We're looking for sessions on: - Building and Sustaining Communities 🔨 - User and Contributor Experiences 🤝 - Project and Ecosystem Growth 📈 More details on our blog: hpsf.io/blog/2025/hp...

PSA, if you’re looking to do something like this, I highly recommend using @spackpm.bsky.social to manage your build environment. You can build NCEP’s GRIB2, BUFR, and “ip” libraries, along with other dependencies like Proj. Would be much harder without it.

Made my day when @jeffgeerling.com stopped by the Texas Tech #SC25 booth to take a look at our x86 mini-clusters that run Warewulf, Ansible, Spack, and complete scientific #HPC applications with the same software stack as on our main clusters.

We’re so excited to share that HPSF has been recognized as the Best HPC Collaboration in the 22nd edition of the HPCwire Readers’ Choice Awards! 🏆 Thank you to everyone who voted for HPSF. We’re excited for what the future of HPC holds! hpsf.io/blog/2025/hp...
