- scheduler/: day/night engine (conf-driven redesign), psi/perfsnap collectors, proxmox-ctl, systemd timer templates — ported from ~/projects/ultix per the breakout map in scheduler/README.md - loop/: perf-loop driver (baseline/audit/tweak/rebaseline), cpu-bench (new CPU leg), baseline-diff (tolerance compare) — smoke-tested locally - docs/ARCHITECTURE.md: full program design (loop, resource groups, VM/spindle balancing, k8s-vs-Slurm, beszel+RAPL/iDRAC telemetry spine, workload classes, solar/HA + two-site power economics) - docs/report-amt-power-telemetry.md + docs/report-moonlight-desktop.md Redmine: https://projects.knownelement.com/issues/826#note-2

# systemd units — day/night profile timers
|
||
|
||
Install per host (adjust names to your unit namespace if not knelperf-):
|
||
|
||
install -m 0644 knelperf-dayprofile.service /etc/systemd/system/
|
||
install -m 0644 knelperf-dayprofile.timer /etc/systemd/system/
|
||
install -m 0644 knelperf-nightprofile.service /etc/systemd/system/
|
||
install -m 0644 knelperf-nightprofile.timer /etc/systemd/system/
|
||
systemctl daemon-reload
|
||
systemctl enable --now knelperf-dayprofile.timer knelperf-nightprofile.timer
|
||
|
||
Design notes (carried from ultix, keep true here):
|
||
|
||
- `Persistent=true` — a missed flip (host powered off) replays at next boot,
|
||
so the host can never get stuck in the wrong profile across a reboot cycle.
|
||
- Services are `Type=oneshot` calling the profile engine with the SAME conf
|
||
file; the conf — not the timer — is the only place values live (fixes the
|
||
ultix wart where the day-flip time was sed-edited on the live timer).
|
||
- Day schedule 07:00, night 22:00 local time (batch window 22:00–07:00).
|
||
Change the OnCalendar here when a host needs a different window; the timers
|
||
stay trivial and identical in shape.
|
||
|
||
Reboot-safety invariant: slice unit files must carry the DAY values as their
|
||
static defaults, so an unattended reboot always lands in day mode.
