There are no pre-planned agenda items: this meeting is just for Q&A

Cameron: Manage an environment on an old system
- Using an environment on a shared FS on this system
- Moving to a new system with same OS but different processor
- Want to avoid reinstalling on the new OS
- And want to reuse older deps
- Peter: if new target is compatible with old target, Spack's concretizer will automatically reuse things
- Todd: reuse is also highly-prioritized so should be common
Nick Romero: https://github.com/spack/spack/issues/39993
- Multiple instances of a package installed for a Spack instance on a shared FS used from multiple systems
- Want spack load to pick the arch of the current system
- Right now have to do spack load hdf5 --target=
- Todd: PR for picking one for the current arch (https://github.com/spack/spack/pull/34991)
- Making one spack env per target would also resolve this
Todd: @Jakov, you might be interested in Tom Scogland's PR that creates a Spack OS
- See: https://github.com/spack/spack/pull/42082
- Includes build of glibc
Pariksheet: Spack Wikipedia page
- History of adoption?
- Large organizations using it
