Metrics and Dashboarding

  • We discussed Caetano's research into dynamic resource Allocation for our Spack CI builds. We are excited to implement his recommendations to improve the efficiency of our CI system! Our plan to do so is as follows:
    1. Use Caetano's results to update the hardcoded KUBERNETES_MEMORY_REQUEST values in [share/spack/gitlab/cloud_pipelines].
    2. Update our generate jobs to dynamically receive memory request values from a new service, falling back to the hardcoded values above if this service is unavailable.

CI pipelines updates

  • We are investigating how to enable/disable stacks without creating a PR to spack. (PR #41381)

Priorities

  • Update resource requests based on Caetano's findings
  • Continue pursuing "costs per job" metric
  • Content-addressable tarballs
