What it does

Ppopp Experiments is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when designing or auditing a PPoPP paper's evaluation, covering the twin bar of concurrency correctness and measured scalability — speedup curves, strong vs weak scaling, core/thread sweeps, NUMA and GPU effects, contention microbenchmarks plus real workloads, variance and measurement hygiene, and honest strong baselines.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Journal-specific Claude Code/Codex skill packs covering mainstream journals — AER, QJE, Nature, Cell, 管理世界, 经济研究 & 200+ more — your fast track to getting published. | 覆盖主流期刊的… The licence is MIT.

When your agent uses it

  • Auditing a PPoPP papers evaluation
  • Covering the twin bar of concurrency correctness and measured scalability — speedup curves
  • Strong vs weak scaling
  • Core/thread sweeps

  • “/ppopp-experiments”

What it can do on your machine

Read from SKILL.md and the folder at commit 932eb23. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ppopp Experiments loads about 1.3k tokens when it runs. Until then it costs about 86 tokens; SKILL.md has 512 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~86
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use when designing or auditing a PPoPP paper's evaluation, covering the twin bar of concurrency correctness and measured scalability — speedup curves, strong vs weak scaling, core/thread sweeps, NUMA and GPU effects, contention microbenchmarks plus real workloads, variance and measurement hygiene, and honest strong baselines.

PPoPP Experiments

Design the evaluation to clear PPoPP's twin bar: the contribution must be correct under concurrency and measurably scalable. A speedup with no correctness argument, or a correctness proof with no scaling data, each fails half the venue. Reviewers are parallel-systems experts who will interrogate the baseline, the machine, and the variance before they believe a number.

Match evidence to the claim

Claim shapeEvidence PPoPP expectsCommon failure it catches
A lock-free/wait-free structureThroughput vs. thread count under varied contention; a linearizability/progress argument; memory-reclamation overheadSingle contention level; "no race seen" instead of an argument
A parallel runtime/schedulerOverhead vs. sequential; strong+weak scaling on real workloads; load-balance behaviorMicrobenchmarks only; no real application
A GPU/accelerator techniqueSpeedup over a strong GPU baseline; occupancy/divergence analysis; transfer costs countedIgnoring host-device transfer; a weak baseline kernel
A parallel algorithmScaling on real inputs; NUMA/locality effects; comparison to the best known implementationOne input; a naive baseline
A memory-model / race toolSoundness/coverage claims; runtime overhead; false-positive/negative characterizationOverhead unmeasured; no ground truth

The scalability story

  • Show the curve. Report performance as a function of thread/core count, not one configuration. The interesting information is the shape: linear region, saturation point, collapse.
  • Distinguish strong vs. weak scaling and label which you show. Strong scaling (fixed problem, more cores) and weak scaling (problem grows with cores) answer different questions; conflating them is a classic PPoPP tell.
  • Sweep the topology. Cross-socket and NUMA effects, thread pinning, and (for GPUs) occupancy and divergence often dominate; a single-socket-only result invites "what about NUMA?"
  • Count the hidden costs. Memory reclamation, host-device transfer, allocation, and scheduling overhead belong inside the reported numbers, not in a footnote.

Correctness under concurrency

  • Provide an argument, not just testing: linearizability (with linearization points), lock-freedom/wait-freedom (progress), or a checked property. "Passed a stress test" bounds confidence but does not establish correctness.
  • Name the memory model you assume (C/C++11 atomics, the GPU model, hardware TSO) and show your synchronization is correct under it, not just under sequential consistency.
  • If you use a model checker or race detector to support the claim, report its configuration and what it covers.

Baselines that survive scrutiny

  • Compare to the strongest real competitor, at the competitor's best settings, on the same machine — not to your own unoptimized code and not to a strawman.
  • Rebuild and re-tune baselines yourself where feasible; citing a competitor's paper number measured on different hardware is not a fair comparison.
  • If you are the first at something, construct the most credible reasonable baseline and justify it.

Measurement hygiene

text
[Repeats]     multiple runs; report median/mean with variance (error bars / percentiles)
[Warm-up]     discard JIT/cache/allocator warm-up; state the steady-state protocol
[Pinning]     pin threads to cores; state the topology and the pinning policy
[Isolation]   quiescent machine; no co-tenants; disable turbo/frequency scaling or report it
[Inputs]      real workloads plus targeted microbenchmarks; state sizes and sources
[Provenance]  exact CPU/GPU, socket/NUMA layout, memory, compiler and flags, OS

A single-run bar chart with no error bars, on an unstated machine, is the evaluation a PPoPP reviewer trusts least.

Anticipate the rebuttal questions at design time

The two questions PPoPP reviewers ask most — "does it still scale at higher core counts / on another GPU?" and "how does it compare to baseline X?" — cannot be answered in the short rebuttal window if the runs were never made. Pre-run the larger core sweep and the obvious alternative baseline before submission so the numbers are already in hand (see ppopp-author-response).

Output format

text
[Twin bar] correctness argument present? scalability curve present? both required
[Scaling] strong/weak labeled, core sweep, NUMA/GPU topology, hidden costs counted? yes/no
[Correctness] hazard + argument (linearizability/progress) under a named memory model? yes/no
[Baselines] strongest real competitor, same machine, tuned? yes/no
[Hygiene] repeats+variance, warm-up, pinning, isolation, provenance? list gaps
[Rebuttal pre-runs] higher core count + alternative baseline already measured? yes/no
