Agenda

  • News

  • Program Administration 
    • Beyond SRDP:
      •  VLA pipeline development?
      • Product owner for Workspaces?
      • Plan is that John stays working on VLA pipeline heuristics for the next few ~years, though bugs and small feature requests can be made by NMOps. NMOps should identify someone to work with John and (eventually) take over. Similarly,  VLA-relevant WS improvements could be done by having Amy or a senior DA move into the product owner role at some point in the future now that major development for VLA is mostly complete.
  • Science Ready Data Products
    • Testing of cal+img underway
      • Expect completion by Monday
    • Pipeline test version pending last ticket that needs minor fix
      • One remaining ticket  PIPE-2350 - Getting issue details... STATUS
      • Again, should be done early next week
    • QA-related pipeline requests in the "no flagging" era
  • VLASS
    • Planning for VLASS-II
      • Now have Texas TACC account set up.
        • Laura will set up meeting to discuss DMS involvement in TACC GPU testing.
        • ML to write plan for DMS needs for VLASS-II, including estimated FTEs, schedule etc.
      • JHU has available computing, but need to pay cash...
      • VLASS-II priorities:
        • Validate pipeline for 1" cubes wit tapering (SECC)
          • Need to profile memory and decide on tapering. Still not clear why SECI cubes needed 187GB in 6.5. Also could consider making cube planes different sizes/samplings and regridding at the end.
        • Validate and profile hpgawp (GPU) pipeline locally (L4s)
          • PIPE-2423 - Getting issue details... STATUS
          • Still needs bug fixing
        • Get awphpg running on different GPUs
        • VLASS manager changes/data origin setup.
          • K Scott has "read only" version running, need to get products back.
      • 30 GPUs arrived, asked K Scott to install 3-4 for testing.
      • Have 200TB of space in /lustre/projects/vlass until Feb 2026 (then goes back to 100TB).
    • Ep3  QL catalog - Dillon to write-up paper with catalogs, we will put them on VLASS website.
    • Dillon's median stack QL images now available from the VLASS cache, ML to write eNews article and contact CADC.
    • New Ep1+2 catalog for SECI masks being tested
      • Seem OK! Juergen will check with Rui about implementation, might just be a recipe change
    • Calibrator uv ranges - Tierra testing.
    • 2.1 SECIs at end of processing chain to be placed "on ice" (~ 100 images) in case improved calibration can be implemented in CASA by the end of VLASS-II
      • Sergio looking into changing PB limit for some of the diverging ones that converged in QL
  • AOB
