News

  • Storage management
    • We are migrating to a system where all production storage is managed centrally by DDM. All files not explicitly locked as needed for production can be deleted by DDM.
    • We need to propose a mechanism how we want to protect data for workflows that are not managed by Unified or L3 experts.
    • Dima: We need to identify use cases for this (i.e. Test workflows, RelVals, etc)

3 top issues affecting production

  • MaxWallTimeMins: some jobs were having very big values, hence not matching in the global pool.
    • Proposed solution: Estimate the MaxWallTimeMins based on job workload (how it's done now) and set Min and Max boundaries (configurable), so no job gets spawned with more than that.
