Agenda items

• (Wileam, Ivan) Ping on https://github.com/spack/spack/pull/26766 https://spackpm.slack.com/archives/C01UZDL35C4/p1652868981688779
• (Wileam) Docker CI failure on Spack forks, e.g. https://github.com/wyphan/spack/actions/runs/2342299106
  • Massimiliano: has a fix for this
• (Evan) How to run spack on clusters to provide modules
  • Unexpected rebuilds on (similar?) clusters
  • Test cluster and larger cluster
  • Want to install packages on test cluster and move them to larger cluster during outage
    • It may be possible to reuse this depending on how it's done
    • Was using binary caches
    • Spack was pulling "about half" of those
    • Externals are in use, but they generally match between the two systems
  • This is with Spack develop just before 0.16
  • Is the CI logic useful for generating a binary cache?
  • New package-reuse logic may be useful for this
• (Matt) Trying to deploy llvm 14 on a machine
  • Includes flang
  • The new flang doesn't support code generation, so uses gfortran
  • If you configure spack to use flang, archspec passes gfortran-style mcpu flags to flang
  • Related: https://github.com/archspec/archspec/issues/49
• Changes to base package class are not reflected in package hash: https://github.com/spack/spack/issues/30720
  • Greg will check in with Todd about this
