Congratulations to the Spack team on reaching this significant milestone!

Hard to believe!

Cant wait to try this out. Huge achievement!

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.

💥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/...

@kermmartian.z80.me and I are hiring for a staff-level DevOps engineer! @spackpm.bsky.social expertise is particularly welcome.

Awesome to see 48 people in the room for the first ever Spack User Meeting at the @hpsf.bsky.social conference! Greg Becker is outlining the road to v1.0 in the opening session. #hpc #hpsf @spackpm.bsky.social

We’re pleased to announce the 2025 HPSF Conference schedule is now live! #HPSFCon will feature technical sessions, panels, discussions, workshops, & meetings for a number of HPSF projects, featuring talks from users & contributors. Here’s a sneak peek at what you can expect: hpsf.io/blog/2025/an...

And there’s soooooo much wasted disk space installing every package 9001 times across venvs. One of the things I like about spack is that there is a global install cache and then it just assembles a local view with links.

Check out the crowd for @spackpm.bsky.social swag post BoF #SC24

Choice paralysis of the day: #Slurm, #Spack and #OpenHPC BoF sessions all scheduled in the same time slot at #SC24. We do love parallelism in the #HPC community.
