# L18 build resources

Limits: CPUs 0–11, `-j12`, normal priority, 6 GiB address-space cap. Governor stayed `powersave`.
These are the final builds after the cell-coverage and owner ceiling corrections.

- Clang 19, `-ffp-contract=off`: exit 0, 31.689 s, peak process RSS 436,088 KiB, peak VMS 586,240 KiB.
- GCC 14, default FP contraction: exit 0, 48.648 s, peak process RSS 903,168 KiB, peak VMS 1,014,716 KiB.
- Largest measured runtime process was the final Clang gate run at 897,276 KiB RSS. The determinism matrix peaked at 603,172 KiB and the crossing matrix at 548,664 KiB.
- An earlier GCC build was interrupted by owner steering before producing a binary; the final GCC build above completed successfully.
