New blog post: Using Spack on top of EESSI: A Proof of Concept Can we convince Spack to reuse software installations available in EESSI to resolve required dependencies when installing QuantumESPRESSO? www.eessi.io/docs/blog/20... @spackpm.bsky.social

"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...

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.

So proud to be recognized as the Readers' Choice for Best HPC Collaboration in HPCwire! Thank you once again to everyone who voted, and everyone who visited us at SC this week! 💚 💙 ❤️

This is excellent news! Spack is an incredible tool within the HPC software management space, but I also use it on my own Linux machine to manage builds and environments. Like conda for compiled code.
