4:30   Where do we go from here?

  • Pipeline talks will be short talks (30 minutes including discussion) on the basics of the various pipelines represented here (including lessons learned)
  • Pipeline demos will be a session of short (10-15 minute) demos of the pipelines represented here. A demo might simply be a set of snapshots.
  • A tour of the GBT will happen at some point. It takes about 2 hours. The paired maintenance days this week are Tuesday/Thursday and Wednesday/Friday. If the only available day is Thursday, then the tour will happen Thursday morning.
  • There will be an informal session on Thursday, November 29th, to flesh out as much of the proposed GBT KFPA data pipeline as possible based on the discussions held the previous 3 days.

Data Pipeline Discussion Topics

This section has been moved to it's own wiki and organized to align with the discussion topics on the agenda for Tuesday and Wednesday. Note that these cover all aspects of the data processing problem and so to some extent many of these are independent of the any automatic processing (a pipeline).

KFPA Data Processing Issues

AOC & CV conference rooms

  • AOC
    • 11/26
      • Auditorium (except from 10-11 AM MST, during lunch in GB)
    • 11/27
      • 317 up to 9:30 AM MST
      • 280 11 AM MST to end of day
    • 11/28 - no rooms available.
  • CV
    • 230 except during TUNA on 11/27 and after 3 PM on 11/28, when it will move to CV-aud.
  • Viewing the video stream. You should be able to do this from most PCs. This will not allow you to participate but can be used during the times when no remote rooms are available. NRAO participants should talk to your local system administrators for instructions and help in setting this up. Non-NRAO participants who wish to try this should e-mail BobGarwood. People on the NRAO network can follow this link to the internal wiki for the URL and phone for remote participation.
