Mobisys Reproducibility

MobiSys Reproducibility

Use this before submission and again before the artifact-evaluation deadline. On-device results are fragile across hardware and framework versions, so reproducibility at MobiSys is mostly about provenance: recording enough of the device and measurement context that someone on a different phone can rebuild the result.

Evidence map

• Map each latency, energy, throughput, and accuracy claim to a verifiable location in the paper, appendix, or artifact package.
• For each on-device result, record device model, SoC, OS build, framework/runtime version, model checkpoint hash, power source, ambient temperature, and thermal state at run start.
• Record the power-instrument setup and the energy boundary so an energy figure can be re-derived rather than trusted.
• For stochastic results, report seeds, repeated runs, and the spread; a single number from a single phone is not reproducible evidence.
• Explain missing data, firmware, or hardware honestly, and describe how a reader could reproduce the result in principle on a different device.
• Keep the artifact consistent with the manuscript; a number in the PDF that the artifact cannot regenerate is a review-risk multiplier and an AEC failure.

What survives a different device

Marking a device result "reproducible" without its provenance is a recognizable MobiSys red flag, because the AEC and reviewers cross-check the artifact against the PDF and read a gap as carelessness about the rest of the paper.

Vignette: an on-device inference paper

Consider a runtime that keeps CNN latency stable under load, validated on four phones. Its reproducibility spine: the four device models and OS builds, the runtime version and model checkpoint hashes, the power-monitor model and sampling rate, the ambient temperature and the steady-state thermal traces, the workload trace, the seeds and run counts — plus one honest sentence about the device it could not test and why the result may differ there.

Degrees of reproducibility

• Turnkey: one script regenerates each figure from logged runs on the target device.
• Scripted: scripts exist but need the specific hardware or manual device setup.
• Descriptive: prose detailed enough that a competent reader could rebuild the pipeline on a comparable device.

For MobiSys, the on-device measurement path should be as turnkey as the hardware allows, and a hardware-optional downscaled or emulator path should let an evaluator without your exact device reach at least Functional (mobisys-artifact-evaluation). State the achieved level honestly rather than overpromising turnkey behavior that fails on a different phone.

Legal and privacy provenance

• Decide early what traces, firmware, and datasets can ship; on-device data often carries user, sensor, or vendor-firmware restrictions.
• Strip identifying content from screenshots, logs, and demo media before release.
• If data cannot ship, provide a synthetic or public substitute and name which results it cannot reproduce.
