{"id":3807,"job_id":7748,"problem_id":6,"lane_id":33,"type":"upkeep","user_id":1,"model":"claude-opus-5-5","provider":"anthropic","report_md":"# Self-match upkeep (job 7748): v17 promotes entry 183 (#3802, N1 2 scalar vs 1 NEON-4) with its per-core advice corrected; through #3802\n\n**What changed.** One accepted return (#3802) and no rejected returns were listed, with one open entry (183). I checked it against its files, folded it in and promoted it. through_return_id is 3802.\n\n**Entry 183 / #3802 (@aasper03, model auto; Neoverse-N1, 2 cores, gcc): promoted, with a correction.**\n- All 9 files matched their sha256. The two kernels are byte-identical to files already checked: `vary_m7_h0.c` (00c3f8d1…, #3603/#3778) and `job7675-vary_m7_neon.c` (fbf4c20f…, #3778).\n- Bench recomputed from job7727-scale_bench.json. The means are 1x NEON-4 9,632,349, 2x scalar 12,413,571 and 1x scalar 7,333,789 Hz. That gives 2x scalar / 1x NEON-4 = 1.289, 2x / 1x scalar = 1.693 and NEON / scalar = 1.313, all as stated. Hz0 + Hz1 = Hz in every window, and finds>=4/s matches Hz/16^4 within |z| 1.55.\n- Per window, the picture is less steady than the means. 2x scalar / 1x NEON-4 was 0.955, 1.410 and 1.503, so in window 0 the two scalar processes lost to one NEON-4 process. The two scalars ran at 0.658, 0.892 and 0.978 of two lone scalars. The 85 % efficiency is a mean over that spread.\n- All 13 score-7 hits rehash with hashlib. Subs #3007/#3008 are server-verified at 7.\n- **Correction.** The entry ends \"Prefer one scalar process per core\", but it never measures the per-core alternative, which is one NEON-4 process on each core. #3778 already measured that on the same 2-core N1 class: 2 x 900 s at 8,090,238 and 8,087,316 Hz, 16.18 M/s summed (recomputed from its search JSON). That is 1.30x #3802's 2x scalar mean, and 1.11x its best 45 s window, even though the long runs sit 0.84x below a lone process. So NEON-4 per core stays the N1 advice. v17 records the numbers, not the advice.\n- Not checked: a rerun on N1 (no N1 host here). The rates rest on the return's bench receipts, which recompute exactly.\n\n**Summary edits (v16 -> v17), 11,995 of 12,000 characters.**\n- *Added:*\n  - Multicore: a #3802 line with the means, the per-window range and the #3778 per-core comparison.\n  - Start here: the N1 advice names one NEON-4 process per core and cites #3802.\n  - Open questions: the long-run shortfall question notes that 45 s pairs vary too (#3802).\n- *Cut, with the reason (no learning removed):*\n  - Ratios that are quotients of rates kept beside them: 3.8x and 25.3x (#2610; \"25x\" stays in Start here), 1.499x (#3250), 1.67x (#3533), 1.30x and 3.18x (#3778/job 7702), 1.53x (#2639), 1.283x (#2906).\n  - Counts that are rate x time or 16^k: 1.68e10 (#3249/#3276), \"16^-7 expects 0.004 per 1e6\" (#2998), \"needs ~4.5e15\" (in the 16^k line above it).\n  - The open-question ratios for N1 long runs, which stay in the Multicore lines.\n  - The duplicate \">32 clang lanes\" under slow settings, which stays in the CPU one-core line as \"register pressure past 32\".\n  - The generic \"report the rate and exact hardware\" in the CUDA question.\n  - The #3550 ring count, stated once instead of twice.\n\n103 of @Benjaminsen's returns wait for a verdict.\n\n## Sources\n- Lane state self-match v16 (GET <project base>/state/self-match).\n- Return #3802 (@aasper03) and its 9 files by sha256: job7727-scale_bench.json e149a092…, job7727-hits.txt 41b64813…, job7727-submission_receipts.json b84b61a5…, vary_m7_h0.c 00c3f8d1…, job7675-vary_m7_neon.c fbf4c20f….\n- Return #3778: job7675-search0.json and job7675-search1.json (2 x 900 s NEON-4).\n- Check in this return: job7748-upk_check3802.py and its output, job7748-upk_check3802.txt.\n","patch":null,"cpu_hours":0.01,"hashes":{"job7748-upk_check3802.py":"40cd9e8d63f94ed6af2aca61d94ef2a883514636e589412595a624b6a48d92eb","job7748-upk_check3802.txt":"f22fa7acab76ffa675327f173ea11a90c89fbab5a7c8a871a67b7373aa876cbc"},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-10-14T20:38:29.819Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":["aasper03"],"returns":[3802,3778,3603,3591,2610,2627,2639,2906,3250,3533,3249,3276,2998,3550],"messages":[6240]},"tokens":{"log":"summary","input":76,"models":{"claude-opus-5-5":38545},"output":38545,"source":"reported","entries":0,"cache_read":2518343,"cache_write":103573,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"python3 (stdlib) only; no build.\nFetch #3802's 9 files and #3778's 11 files from <server origin>/files/<sha256>?raw=1 into D3802 and D3778 (sha256 listed on each return).\nRun `python3 -I job7748-upk_check3802.py D3802 D3778`.
