HPCA Reproducibility

Use this to make an HPCA paper's results reconstructable — by a reviewer during the window, by an artifact evaluator after acceptance, and by you six months later when the environment has drifted. HPCA's artifact badges are IEEE reproducibility badges earned on a separate AE HotCRP, so build toward that pipeline, not the ACM one.

Pin the result chain

Every figure in the paper should trace back through an unbroken chain:

simulator commit (or machine + firmware)
  -> configuration file (core, cache, DRAM, interconnect)
    -> workload + input + sampled region
      -> raw output logs
        -> statistics script
          -> the figure/table in the PDF

If any link is unpinned — a simulator built from "latest," a config edited by hand, a region chosen ad hoc — the result is not reproducible, only re-runnable by you.

One manifest per figure

Give each headline figure a manifest that names its commit, config, workload, region, seed/trial count, and the exact command that regenerates it. A regen.sh per figure that reproduces the artifact from raw logs turns "trust me" into "run this."

Chain link	What to pin	Failure if unpinned
Simulator	Commit hash + local-patch diff	Silent behavior drift between builds
Config	Versioned file, not manual edits	Unreproducible operating point
Workload/region	Suite version + sampling recipe	Cherry-picked region suspicion
Statistics	Scripted, seeded	Numbers that cannot be regenerated
Silicon runs	Governor/turbo/SMT/NUMA + kernel/firmware	Noise mistaken for signal

Record machine state for silicon

A real-hardware result is only reproducible with its host state captured: frequency governor, turbo, SMT, NUMA policy, kernel and firmware versions, and the trial count with dispersion. Archive it next to the logs, not in your memory.

Handle non-redistributable workloads

SPEC-class and other licensed suites cannot ship in the artifact. Provide the recipe and checksums to reconstruct them, plus at least one freely available workload that exercises the full pipeline so an evaluator without a license can still reproduce a headline result.

Keep the environment resurrectable

Between submission and the badge round, environments rot. Containerize or script the build, pin dependency versions, and do a cold-start resurrection drill on a clean machine before you promise a reviewer or evaluator anything. The single rebuttal/revision window is not the time to discover your simulator no longer builds.

Reproducibility checklist

[Result chain] every figure pinned commit->config->workload->region->stats? (Y/N)
[Manifests] one per headline figure with a regen script? (Y/N)
[Silicon state] governor/turbo/SMT/NUMA + kernel/firmware + trials archived? (Y/N/NA)
[Licensed workloads] recipe+checksums + one free workload provided? (Y/N/NA)
[Resurrection] cold-start build drill passed on a clean machine? (Y/N)
[Badge readiness] packaged for the IEEE AE HotCRP? (Y/N)
[Top gaps] <ordered>
