    • Finalize rsync mechanism for CVMFS
    • Finalize random trigger delivery to compute node

Notes

Present: Thomas Britton, Mark Ito, Richard Jones, David Lawrence

  • Reviewed Mark's summary of progress on the OSG. See his blog post for the details.
    • Timeline: milestones since the collaboration, including successful run of simulation on the grid with a recent software release
    • Features: jobs on grid nodes will see an abridged version of the JLab /group/halld tree.
    • Modifications: review of a couple of modifications made to Richard's original scheme
    • Container dance: Mark re-described the Singularity-container distribution mechanism that Richard described at the last meeting.
    • Minor issues: some details to be worked out
  • Items to work on for the OSG (Thomas)
    • Hooks for a database to track job progress and job statistics in MCwrapper.
    • Finalize rsync mechanism for CVMFS (code and constants).
    • Finalize random trigger delivery to compute node (for mixing in accidental background using real events).
    • Mechanism for transfer from scosg16:/osgpool to farm:/cache (files cannot be brought back directly to /cache or /volatile, they arrive first on the submit node).
