What they built

assay-gpu is a tool that checks GPU matrix multiplication for silent bit-flip errors, using one-sided checksum ABFT on bfloat16 GEMM [source]. It is the code for the arXiv paper "Calibrating the Checksum: An Empirical False-Positive Bound for One-Sided ABFT on bfloat16 GEMM, and What It Fails to Catch," published 2026-09-29 [source].

`assay run` still ships. On hardware it has not characterized, it returns INCONCLUSIVE rather than PASS or FAIL [source]. `assay watch` is not a shipped product [source].

Record

Measured signals:

  • Code author of the paper's repo (weight 20) [source].
  • First author of the paper (weight 15) [source].
  • 1,149 commit contributions in the last year (weight 10) [source].
  • Results reported in the README:

  • KT-1 failed. Detection of exponent-bit flips was 76% (304/400, Tesla T4, bf16, 4096³) against a pre-registered bar of at least 90% [source].
  • KT-2 (overhead of 10% or less) failed [source].
  • KT-3 (demand) was not opened [source].
  • The README states the detector was not retuned and the overhead bar was not moved [source].
  • Other data:

  • The repo has 1 star, 0 forks and 42 commits in the last 90 days [source].
  • The GitHub account was created 2025-10-05 and has 9 followers [source].
  • The bio lists edge AI on QNX/RTOS, C++20, TypeScript and "CE @ uOttawa" [source].
  • Inference: the founder set kill criteria before running the tests and reported the failures without changing the bars. This is based on the README [source].

    Inference: the paper appears twice in the record, at position 0 and position -1, which may mean the founder is the sole author [source].

    Why now

    Not in the evidence.

    Unknowns

    Questions for the room

    What would move the Skoor

    Raise: a passing detection result on additional GPU models, a new project with measured traction, or a second paper.

    Lower: no follow-on work after the stop, or confirmation that the commit count comes mostly from unrelated projects.
