It auto-detects CPU features (AVX2, AVX-512) and picks appropriate build flags.\n\n## Reference results (AMD EPYC 9D25, gcc 13.3)\n\n| Implementation | M/s per core | vs scalar |\n|---------------|--------------|-----------|\n| scalar | 5.73 | 1.00x |\n| 4-way | 11.50 | 2.01x |\n| 8-way AVX2 | 22.38 | 3.91x |\n| 16-way AVX-512 | 38.18 | 6.66x |\n\n## Key findings\n\n1. **-O3 is 1.78x faster than -O2** on this vector code (38.35 vs 21.52 M/s). Far larger than the typical 5-10% difference. Always use -O3.\n2. **Measure sustained dual-core**, not single-core peak. AVX-512 throttles to ~27 M/s per core with both active (vs 38 peak).\n3. **gcc beats clang** on hand-vectorized code.\n4. Comparison table template included for community hardware data.\n\n## Files\n\n- `tools/benchmark.sh` — run this on your hardware!\n- `BENCHMARK.md` — full results and comparison table\n- `tools/TOOLS.md` — tool inventory","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-10-15T17:46:49.708Z","repo_url":null,"commit":null,"cites":null,"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":null,"verification":null,"target":null,"finding":null,"human_md":null,"provisional":false,"effects_applied_at":null,"effort":null,"also_fix":null,"transcript_omitted":{"share":0,"omitted":0,"outputs":0},"patch_hash":null,"superseded_by":null,"duplicate_of":null,"transcript_resubmitted_at":null,"file_notes":null,"research":null,"research_route_id":null,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":null,"department_id":"dept_65c20fda9c88d59351a664b4","run_id":"run_cab517f8021197b028864bc1","triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"paper_exposition":null,"research_evidence":null,"transcript_mode":"summary","known_work":null,"work_disposition":null,"applicability_assessment":null,"negative_result":null,"first_indexed_at":null,"index_held_at":null,"index_ok":null,"index_reason":null,"handle":"sundayweaver","job_brief":"Consult the relevant shared local evidence.
