Description

Raw recordings, logits, plans, run outputs and analyses behind the preprint "Accuracy is not compatibility: two Evo 2 checkpoints hinge on one FP8 matrix multiplication", which the software repository summarises but does not hold. D1: the RTX 4060 FP8 tensor-core hardware ground truth (173 recordings, manifest SHA-256 be1270ed64432a1311ab5e2c98ccb69028f72e3424ad4c6148d4cd468fba6695), as one tar. D2: the raw output of the H100 PCIe probe of 15 Oct 2026, including the full output bits of the 21 FP8 projections of Evo 2 1B. D3: the live split-K calls of the H100 PCIe sweep of 16 Oct 2026. D4, D8: the H100 PCIe official Evo 2 1B and 40B bf16 logits. D5: RTX 5070 Ti Evo 2 1B per-position log-probabilities. D6: the RTX 4060 official Evo 2 1B and 40B logits. D7: the plans of the two H100 rentals (Chinese, with English summaries in the README). D9: the plan and results of runs A7, A9, A11 and A12. D10: the locally hashed (self-attested) localisation plan PLAN_C with its deviation log, code, outputs and block-0 tables. D11, D12: the matched residual interventions (35 Evo 2 1B cells; plan, code, results; captured tensors). D13: the RTX PRO 6000 follow-up on a CUDA 13 stack (1B, 7B, 40B; forward, generation and BRCA1 tests; operator comparisons). D14: the RTX 5070 Ti Evo 2 40B BRCA1 500-variant follow-up. D15: the RTX 4060 exploratory probes of 10-11 Oct 2026. D16: the paper's number ledger, post hoc analyses and figure scripts. The software, mmaemu 0.1.0, emulates a reference GPU's FP8 GEMMs bit for bit on the recorded evidence; the rest of Evo 2 runs natively, so whole-model outputs are close to the reference GPUs', not identical. Plans and logs were scrubbed of instance identifiers, host names, key names, AI-assistant session paths and local account information (exceptions kept as recorded where checksums pin the files: six members of the D1 tar and one PLAN_C script, see README.md); README.md lists every placeholder and FILES.tsv every file with its SHA-256.

Technical info (English)

Each item directory is deposited as one zip archive. Download all files into one directory, unzip every archive there (for z in *.zip; do unzip -q "$z"; done) and verify with sha256sum -c SHA256SUMS (macOS: shasum -a 256 -c SHA256SUMS); ARCHIVES.sha256 lists the SHA-256 of every other deposited file. D12 (about 13 GB of captured tensors) belongs to D11; copy its runs/ into D11's directory to check D11's MANIFEST.sha256. Arrays are numpy .npz (load with allow_pickle=False). PyTorch files (.pt: block-0 tables, captured tensors, two recordings in D1 and D2) are Python pickles: load them only with torch.load(..., weights_only=True). D1 replays with tools/replay_truth.py of the mmaemu repository (MMAEMU_TRUTH_DIR=<dir>/tcemu_ada_truth). Scripts read inputs from absolute paths on the author's workstation; README.md maps them to the deposited items. Clock times are Pacific time (PDT) unless marked Z (UTC).
