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

Prentice: how to see variants on two different specs
- spack find --variants
- In the same way you get more details from spack spec, you can also do it with spack find
Prentice: issue with environment matrix "mixing" compilers
- specify combination of mpi/compiler, rebuild for each combo
- some things built with gcc link against another compiler
- Peter: this can definitely happen in some reuse cases
- One strategy: one environment per combination
  - There's ways to avoid duplication across envs
  - You could also make a "load-everything" module (so you don't have users use spack load)
Jason: snap for Spack
- See: https://snapcraft.io/spack
  - Jason: I created the snap to install Spack on a system, and automatically configure it for a general admin use case (e.g. setting up config etc.)
- Todd: what is the procedure? https://forum.snapcraft.io/t/verified-accounts/34002
  - Someone from Spack goes on the forum and offers to become the publisher
- Make an account on the forum
Dom: compiler matrix and mixing compilers within DAGs for concretization
- Massimiliano: will contact you about upcoming feature to control this more (i.e. a way to enforce unification on a per-compiler/mpi combo)
