ci / audit (push) Failing after 26s
- 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

# KNELPerf CPU benchmark — the missing CPU leg of the perf loop (#826).
|
|
# Runs ON the target host (or locally). Zero-install friendly: uses openssl
|
|
# (always present) plus sysbench when available. Output = TSV tag/value.
|
|
#
|
|
# Design notes:
|
|
# - openssl speed = single+multi core crypto throughput (stable, comparable)
|
|
# - sysbench cpu (if installed) = integer event rate
|
|
# - /proc-derived context: governor, PSI at capture time
