CUDA map normal cache: retained compiler cache¶
| Scope | Previous (s) | Lazy fused normals (s) | Ratio |
|---|---|---|---|
| Complete fresh process | 10.814164 | 9.595271 | 1.127x |
| Complete map evaluation API | 5.174729 | 3.945734 | 1.311x |
All 8 processes are retained, including first initialization and compilation. The retained cohort has 4 alternating pairs. Cold mode starts each worker with a separate empty cache. Retained mode starts each method's cache empty and retains it across its subsequent fresh processes. No warmup, timing exclusions or discarded observations enter these medians.
Every original byte is preserved, including operator input paths in provenance.

8d7a6477343d2a727ae02c86704fe8c76f894c5c. Both source trees, actual-import hashes, exact
launchers/schema, complete observations/results, timings and cache-file hashes
are bound by publication-index.json. Raw scans and compiler binaries are external.
The measurements use an unreserved host and are descriptive, with no portable
speed guarantee. This is the existing copied-sensor KITTI execution control,
not independent two-LiDAR calibration accuracy or bag decoding/odometry timing.
