A huge milestone indeed! Congratulations to the entire team!
We don't train AI on data from the world. We train it on words people have said about the world. A stream doesn't rise higher than its source.
Hard to believe!
💥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/re…
Congratulations to the fine folks who made it possible!

@spackpm for sure. It’s historically a bit slow but getting faster. Real nice constraint solving system, so so easy to write/debug packages.
ICYMI the 1st @spackpm user meeting was a success! @tgamblin: “I always wanted Spack to be used widely but never imagined this many people would be working on it." computing.llnl.gov/about/newsroom… #OpenSource #Software
For the first time - user-space Kubernetes running under @FluxFramework on a production cluster. This is OSU and LAMMPS. This has been months of work and persistence. We got this working on an old kernel and hugely strict security policy. Experiments + more details coming soon!🥳
