Travel Info:

  • LOCATION: 320 Whitmore (Institute for Gravitation and the Cosmos) University Park, PA
  • For those who have requested a hotel, please work with Courtney asap on your reservation.
  • Although sometimes a bit more expensive and with slightly less convenenient itineraries, it is almost aways the best thing to fly to State College Airport.

Tentative Schedule:

This is a working meeting. Bring your laptops. We will code nonstop from the first afternoon onward.

IT IS EXPECTED THAT EVERYONE WILL COMPLETE AT LEAST ONE MR PER DAY STARTING IN DAY 2 - PROBABLY MORE

Goals and motivations of this meeting
  • Moderinize the offline (and online as time permits) GstLAL inspiral pipeline with SGN and PyTorch
  • End up with no GstLAL dependency
The path to parity
How to set up an SGN development environment
  • TBD notes from Yun-Jing and Jim (should be posted on actual documentation site)
Your first SGN element and pipeline
  • JIM WILL DO THIS
Hand on with the CBC pipeline
  • An example running on white noise (could be done on laptop)
  • An example running on frame data (probably done on the cluster)
The journey to transformation
  • Describe the plan of work for the week
The self you can give
  • This is where people sign up for stuff to accomplish this week.
HACK SESSION ONE

  • Getting a complete replacement for the offline PSD DAG

    • Write sgn_reference_psd (Ryan Magee, Anushka Doke, Shio)
    • Write sgn_median_of_psds (a cut and paste from gstlal with care given to how it fits into the libraries) (Ryan Magee, Anushka, Shio)
    • Write an sgn_reference_psd_dag built on ezdag OSDF aware (Cort Posnansky, Patrick Godwin)

  • Porting and improving the SVD code

    • Make an sgn_inspiral_svd_bank (mostly a cut and paste) (Surabhi Sachdev, Manvi Jain, Stefano Schmidt)

  • Getting a complete injection frame dag working

    • SGN LIGO injection source - CBC only for now (Victoria Niu, Jim, Sarah)
    • Frame Writer (Zach, Shomik)

  • Strike dev list

  • Output files

    • Hardening output file stuff - add segment tables, process tables and the like? (Yun-Jing Huang, Chad Hanna, Jim Kennington)

  • Handling runtime control

    • Bottle (Ron, Yun-Jing, Chad, Jim)
    • Signal Handler (Ron, Yun-Jing, Chad, Jim)
HACK SESSION TWO
  • Make an sgn_inspiral_svd_bank_dag built on ezdag OSDF aware (Cort Posnansky, Patrick Godwin)
  • [SVD bank conversion to H5 (Ryan Magee)]
  • SGN LIGO injection source - CBC only for now (Victoria Niu)
  • [strike_inspiral_marginalize_likelihood (Leo Tsukada)]
  • Combine triggers across times / cluster triggers by XX / Simplify triggers??? / merge and reduce (Cody Messick, Ryan Magee, Surabhi Sachdev)
HACK SESSION THREE
  • Calc likelihood (???)
  • Extinct bin (???)
  • Calc rank pdfs (???)
  • Compute far (???)
  • Trigger dag with ezdag and OSDF aware
  • Plots, plots, plots
  • The injection workflow (formats, splitters, snr, injection finding)
HACK SESSION FOUR
  • Rank dag with ezdag and OSDF aware
  • Plots, plots, plots
  • The injection workflow (formats, splitters, snr, injection finding)
ACTIONS BEFORE THE MEETING
  • “finish” stillsuit / sgn-event integration
  • Standardize on stride offset? get some elements converted over?
  • LIVE Test source
  • Code quality control in place for all the sgn*, stillsuit, etc. - Get it all development ready.
  • Getting dev environments working trivial.
  • Demo where people can download frame files from GWOSC for the CBC pipeline.
NOTES
  • bottle implemented as a source element and elements that can be controlled have flow control sink pads.
