High performance computing is highly dependent on validated and tested environments that are tuned for specific hardware to yield good performance. Spack enables users to construct their own software stacks, but does not provide the benefits of a centrally curated environment. We implemented new features in Spack to support co-existing system-wide deployments and user Spack environments, and a Spack-enabled global environment with them. This had the result of improving the global environment's portability and the efficiency of Spack use on a production system
