solprop.calibration

Calibrating the native backend to its machine (SEP 46).

The native backend’s CPU execution settings (how each operation threads, how idle threads wait, how wide the team is) are fitted to the machine by a bounded, one-off measurement, kept in a per-user store in the platform’s cache directory and applied by every later run, which records the settings it used in its metadata (calibration). Without a profile the native backend runs its built-in table.

This package reads, shows, exports, imports and clears profiles without loading the native extension. The manual page is docs/guide/performance/calibration.md.
