Measured results

Current SM120 v71 runtime results

The current TP2/EP2 route128 validation artifacts are published under runtime-results/v71. They include the complete five-run FP8 and calibrated-NVFP4 MLA KV-cache KLD receipts, v71 workstation pair prefill and C1 decode receipts, the later C1-C16 stress matrix through the nominal 128K harness row, and a postable plain-text .log summary. See the main model card for the exact regime, results, capacity limitations, and thermal caveats.

Direct packed TP2 serving result

  • Mean BF16-teacher-to-runtime KLD: 0.022750847877671544
  • Scope: sealed final-0000, 2,047 causal prediction positions
  • Context: 2,048 input tokens
  • Top-1 agreement: 0.9384465070835368
  • Report receipt SHA-256: 2cfd1b90a65162784de5b67e1b05ef7a15f98979b77156092d5f7500c607ba67
  • Runtime-logits file SHA-256: 280c12452f429a79724cd1715a5bed2462de98a547746a80f04e7b8cdcd34746
  • Report: tp2-runtime-window-kld.json
  • Qualification: tp2-runtime-qualified.json

This is the measured 0.022 result from the actual packed two-GPU runtime. It is the serving qualification result, not one of the five offline full-panel runs.

Five cold offline decoded-K4 runs

Run Mean KLD Report
1 0.024554564249958208 run-1-kld-report.json
2 0.024554564249958208 run-2-kld-report.json
3 0.024554564249958208 run-3-kld-report.json
4 0.024554564249958208 run-4-kld-report.json
5 0.024554564249958208 run-5-kld-report.json

Each accepted run covers the same 25 sealed windows and 51,175 causal positions. The aggregate receipt is five-cold-run-kld.json.

The original fifth attempt received an external SIGTERM before writing logits and is excluded. Accepted run 5 is the clean run5b retry. Its different name records that operational retry; its measured KLD equals the other four accepted runs.

Exact five-run reproduction scripts

The source used for the accepted offline decoded-K4 measurements is preserved in this repository:

  1. capture_glm53_packed_k4_student_logits_ep4.py launches with torchrun --nproc-per-node=4, loads the immutable BF16 source checkpoint under Transformers EP4, independently decodes the hash-verified packed K4 experts into each rank's local BF16 expert parameters, and captures float32 student logits for the 25 qualification-only windows.
  2. measure_glm53_packed_student_kld.py computes tokenwise KL(BF16 teacher || packed-K4 student) in float64 over all 51,175 jointly valid causal positions and seals the per-token, per-window, per-domain, top-1-agreement, and aggregate results.
  3. aggregate_glm53_five_run_kld.py accepts exactly five independently sealed KLD reports and produces the five-cold-run mean and dispersion receipt.

Each accepted run begins with a new capture process and model load. The capture script is deliberately fail-closed: it requires the exact full-hash BF16 inventory, uniform-K4 contract, content-addressed packed surface, qualified MTP45 adapter receipt, and sealed token-panel receipt used by the campaign. This is the offline decoded-EP4 measurement that produced 0.024554564249958208; it is not the separate packed TP2 runtime measurement that produced 0.022750847877671544.
