Introduction
Spack is a multi-package setup and build system. It replaces UPS and MRB (Multi-Repo Build) and related packages. The computing division will work to build and provide their software (art, ifdhc) within spack. Mu2e will probably not use the spack build features, but will have to use spack to access pre-built software, instead of ups setup command.
Usage
source /cvmfs/mu2e.opensciencegrid.org/setupmu2e-art.sh source /cvmfs/fermilab.opensciencegrid.org/packages/common/spack/rollout/NULL/share/spack/setup-env.sh
and some useful commands
spack -h spack find - spack find
You can see the common lab packages are available in spack: ifdhc, jobsub_client, sam_web_client.
