Ppopp workflow

PPoPP Workflow

Plan the whole cycle backward from the submission deadline. PPoPP's calendar is entangled with the co-located HPCA/CGO/PPoPP/CC week, so several dates (artifact evaluation, camera-ready, registration) move in step with CGO. The dates below are the PPoPP 2026/2027 snapshot read on 2026-07-09 (see resources/official-source-map.md); reopen the live Important Dates page first, and confirm whether the year runs one submission round or two.

The cycle at a glance (PPoPP 2026, the 31st edition)

Sep  1, 2025  Full-paper submission (abstract 100-400 words + PDF), AoE
Oct 27-29     Author-response period (the rebuttal window)
Nov 10        Author notification
Nov 17        Artifact submission to the AE committee
Jan  5, 2026  Artifact-evaluation notification
Jan  9, 2026  Final (camera-ready) paper due
Jan 31-Feb 4  Conference, Sydney (co-located with HPCA/CGO/CC)

For PPoPP 2027 (the 32nd edition, Salt Lake City, March 20–24, 2027), the summer round posts submission 3 August 2026 (ppopp27-summer.hotcrp.com), author response 6–8 October 2026, notification 26 October 2026. Whether a fall round also runs is 待核实 — confirm before you assume a second bite.

Backward plan from the deadline

T-0    Submission: 10-page two-column acmart PDF + 100-400 word abstract, double-blind
T-1wk  Freeze the scalability figures; run the double-blind sweep; set PC+ERC conflicts
T-3wk  Final experiments: fill in the core sweep, the strongest baseline, variance bars
T-6wk  Draft complete; run ppopp-writing-style and ppopp-experiments against it
T-3mo  Lock the study design: machines reserved, topology recorded, seeds fixed

The unmovable PPoPP-specific risk is machine time. Speedup curves, NUMA sweeps, and GPU runs need reserved, quiescent hardware; a shared cluster the week before the deadline yields noisy, unrepeatable numbers. Reserve the machine, and record its exact topology, before you need the final figures.

The rebuttal window (author response)

• The author-response period (PPoPP 2026: 27–29 October 2025) is a fixed 2–3 day window between reviews and notification. Treat it as a scheduled deliverable, not a surprise.
• It is short and word-capped; you cannot run a month of new experiments. The experiments that answer "does it scale?" and "what about baseline X?" must be anticipated and pre-run before reviews arrive. See ppopp-author-response.

After notification

• Accepted for a talk: proceed to the artifact round and the camera-ready.
• Automatic poster consideration: a paper not accepted for a regular presentation is automatically considered for the poster track, with a two-page summary in the proceedings — a real, citable outcome. Decide in advance whether you would take it.
• Rejected outright: reroute via ppopp-topic-selection (CGO/PLDI/ASPLOS/SC or a later PPoPP round) rather than resubmitting unchanged.

The artifact round (post-acceptance, CGO-shared)

• Artifact submission comes about a week after notification (PPoPP 2026: 17 November 2025) and evaluation runs into the new year (notification 5 January 2026). It is separate from and independent of the camera-ready.
• PPoPP's AE culture is shared with co-located CGO; confirm each cycle which committee runs it and which badge set applies. Build the reproducible package now — ppopp-artifact-evaluation and ppopp-reproducibility — not after the camera-ready.

Camera-ready and presentation

• Camera-ready (PPoPP 2026: 9 January 2026) de-anonymizes, completes ACM rights/metadata, and fixes the artifact DOI and any earned badges — see ppopp-camera-ready.
• Presentation happens inside the co-located week; at least one author registers and presents. Registration and travel for the HPCA/CGO/PPoPP/CC venue are shared logistics — book early.

Calibration and reverify

• Confirm the number of submission rounds and every date on the current Important Dates page.
• Confirm the artifact deadline is post-acceptance and CGO-shared, and the exact badge set.
• Do not assume last year's cadence; the summer/fall split is exactly the kind of thing that moves.

Output format

[Cycle target] PPoPP 20XX (edition), submission round, location, co-located family
[Critical path] machine reservation -> experiments -> draft -> double-blind -> submit
[Rebuttal readiness] pre-run experiments for the likely "does it scale / baseline X" asks
[Post-notification] talk / poster (auto-considered) / reroute
[Artifact] AE submission date, badge target, CGO-shared? camera-ready separate
