Module auto 

Auto sizing: which profiles’ memory, slots and cpus the daemon changes now, from the advice, the runs since each profile’s last change and the limits [sizing] and each profile set. Pure: the daemon reads the history and when each profile last changed, writes each change through the config check as PUT /v1/config does, and records it. Never lowers a profile while a job is on its cap, never changes memory from fewer than [sizing] min_jobs jobs, never lowers within [sizing] interval of a profile’s last change or raises within raise_interval, never leaves a profile outside its bounds, and sizes each profile against the budget the changes before it in the same look leave. Moves cpus only on the CPU averages of runs at the profile’s current cpus since its last change and since the daemon got them, never on CPU peaks: a parallel build peaks at whatever cap it gets.

Structs

Context

What auto sizing reads besides the config and the history.

Look

What a look does: the changes changes picks, and the cpus raises it cannot make.

Functions

changes

The changes to make now, in order, one per profile at most. Empty unless [sizing] auto is on.

next_look

The changes changes picks, and the cpus raises the same look cannot make.
