Agendas and summaries for Calyx meetings

Next Meeting

  • Updates
  • Summer plans: Talk to Rachit, Adrian
  • Wrap up plans: Make issues for wrapping up tasks
  • (Virtual?) Farewell for graduating folks!

Friday 9

  • Andrii: Figure out locations in source code to change to implement bounded loops
  • Alex: Figure out why the second example in infer-static-timing fails
  • Chris: Fixed point stuff with his fixed point friends

April 2

  • Karen: Is #327 done?
  • Alex: Constants in invoke #447
  • Andrii: Bounded Loops #338
  • Recap of fixed-point progress (and removal of constants)
  • Griffin: thoughts about register unsharing

March 26

  • Graph coloring merger (#444)
    • and how it broke performance (#459)
  • Two's complement fixed-point (#445)
  • Recap the group timing fix (#446)
  • Chris gave a great ADA talk!
  • Primitive vs. non-primitive component signatures (#457)

March 19

  • Chris: Update on FP, FP representation, and other open PRs
  • YooNa & Karen: Current state of interpreter + planning a demo
  • Alex, Andrii: Demo implementation & next steps
  • Griffin: Update + Next steps
  • General state of issues and PR (let's start knocking them off!)

March 15

  • Recap of fixed-point progress from Chris (#421)
  • Griffin; Finding a new meeting time
  • Welcoming & onboarding Andrii

Mar 8

  • A real fixed point library and numeric system
    • The current library isn't that good and well tested
    • The FP operators are the same as the bitnum ones. No reason to keep them separate.
  • Only if there's time: brief overview of modules thoughts (#419).

Mar 1

Feb 22

  • Interpreter design discussion.
  • [Adrian] ADA demo.
  • Exponentiation?
  • Public-facing website update?

Feb 15

  • Merging #292.
  • Relay status and Dahlia frontend issues (if any)
  • State of demo website.
    • For the future, maybe: setting up a "marketing" website, GitHub Discussions.

Feb 2

  • Systolic array speedup mystery updates (postponed)
  • Relay
    • Quantizing networks
    • Testing integration
  • NTT
    • Add milestone for compiling NTT-256.
  • Invoke ports

Jan 26

Jan 19

  • NTT implementation: Try parallelizing the programs by either unrolling the Dahlia loops or writing a butterfly transform generator in Calyx.
  • Talked about pipelining operator and the need for interfaces that can catch when certain signals arrive.
    • Some notion of how long a signal needs to stay "alive" for (in number of cycles) seems important when doing this.
    • The interface should capture initiation intervals (II) for the pipeline
  • Relay
    • Get VGG working to the point where the whole VGG program can be simulated on Verilator.
