no-GUI is now just the normal entry minus the GUI: bee.gui=off with
bee.nvidia.mode=normal (drops the previous gsp-off/pci=realloc it had picked
up). fail-safe is now simply the GPU/PCIe-workaround boot —
bee.nvidia.mode=gsp-off pci=realloc iommu=pt over the standard base — instead
of the old noapic/nodma/nomce/nolapic/nosmp minimal mode, so it can actually
run GPU tests (nvbandwidth) to verify the iommu=pt half of the vendor fix.
Applied identically across all four sources (grub.cfg + live.cfg.in templates
and build.sh write_canonical_* generators).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The GRUB and isolinux menus (and their two sources of truth — the staged
templates and build.sh's write_canonical_* generators that rewrite the built
menu) had drifted: GRUB shipped a lean set, isolinux carried extra
display-debug entries (gsp-off, kms, kms-gsp-off) and lacked a WIPE entry in
the canonical writer. Collapse all four to one set:
normal, load-to-RAM (default), no-GUI/troubleshooting (gsp-off, pci=realloc),
fail-safe, WIPE ALL DISKS, Memory Test, + UEFI Firmware Settings (EFI only)
The fail-safe entry gains iommu=pt (AMD-Vi passthrough) — the OS-side half of
the vendor fix for the MSI CG480-S6053 cross-socket nvbandwidth reboot; ACS
can't be toggled from a stock-kernel cmdline so that stays a BIOS setting.
default stays index 1 = toram (config.cfg set default=1).

Replaces the old nvbandwidth-all-gpu-power-watch scenario (dropped: the
power/IPMI-sampler framing was a dead-end — the blackbox shows every other
load test, incl. NCCL all-reduce across all 6 GPUs, passes with power fully
connected; only nvbandwidth on cross-socket GPU P2P reboots the box).
nvbandwidth-acs-ab is a two-phase reproduction for the MSI CG480-S6053 case.
Phase 1 disables PCIe ACS redirect at runtime via setpci (saving each
bridge's original ACS control word to /run/bee-acs-orig) then runs
nvbandwidth across all 6 GPUs — expected to survive. Phase 2 restores the
saved ACS values and repeats — expected to reproduce the reboot. Safe phase
first so its full blackbox reaches the USB stick before the risky phase can
reset the box (sync-bracket before the final job flushes phase-1 evidence).
ACS mutation runs via `bash -c` since scenario cmd is exec'd directly with no
shell. Both shipped copies (repo scenarios/ and image overlay) identical;
verified both parse via ParseScenarioJSON (4 jobs).

`bee run <scenario>` called platform.System.RunScenario directly with an
empty base dir, which defaults to /var/log/bee-sat — a tree the blackbox
worker does not mirror (it mirrors DefaultExportDir, /appdata/bee/export).
So a scenario launched from the CLI wrote its logs where blackbox never
looked: the sync-bracket hooks fired and flushed the export dir, but the
scenario's own output never reached the USB stick. The web-UI path was
unaffected because it goes through App.RunScenario, which defaults the base
dir to DefaultSATBaseDir (under the export dir).
Route the CLI through App.RunScenario too — matching the doc comment that
already claimed both paths did — so `bee run` output lands under the mirrored
export tree and shows up in the blackbox capture.

The Scenario page's Run button enqueued a task with target "scenario" that
never launched any load: the queue runs each task in an external
bee-worker subprocess (RunPersistedTask -> executeTaskWithOptions in
task_runner.go), whose target switch had no "scenario" case, so the task
died with "unknown target: scenario". The case had only been added to
taskQueue.runTask's switch in tasks.go — a stale copy exercised solely by
unit tests, which is why the tests passed while the button did nothing.
Add the "scenario" case (ReadScenario -> ParseScenarioJSON -> RunScenario)
to executeTaskWithOptions, and collapse runTask into a thin delegate to it
so there is a single target dispatch. The old runTask switch had already
drifted into a subset (missing nvme-format, *-write, raid-*, nvidia-config,
...); removing it eliminates the divergence that hid this bug. Also drop the
now-orphaned taskQueue.statusDB helper.

nvme-cli emits large 64-bit counters as JSON-quoted strings on some

{lo,hi} objects, so power_on_hours/data_units_read/data_units_written

handled this correctly. Unify both paths on a single exported

Show an explicit per-source status line after "Read All" instead of hiding
failed/blocked sources in a "(skipped: …)" tail. Sources blocked by a missing
Supermicro license (SFT-OOB-LIC / SFT-DCMS-SINGLE) are flagged in red with an
actionable message, so engineers see that SAA DMI is gated rather than silently
falling back to the futile ipmitool FRU path (BIOS re-syncs FRU from DMI on boot).

"inactive" to the OK service states: the fixture now uses a failed service and

nvme-cli emits smart-log counters as JSON strings and uses field names
avail_spare / percent_used instead of the prose names in the NVMe spec.
The nvmeSmartLog struct had int64 fields with wrong JSON tags — Unmarshal
returned an error and the whole health block was skipped, leaving every
NVMe drive with status=Unknown.
Fix: switch all numeric fields to jsonInt64 (already used for lsblk
block sizes) which accepts both bare numbers and quoted strings, and
correct the avail_spare / percent_used tag names.
Also fix validateIsVendorGPU for NVIDIA: previously counted any NVIDIA
PCIe device (including NVSwitch bridges) as a GPU, producing wrong
estimates (12 instead of 8 on an HGX H100 system). Now requires
device_class to be videocontroller or processingaccelerator, matching
the existing AMD filter logic.

Bee Services: treat inactive as OK — oneshot services (bee-sshsetup,

\b does not fire between a digit and '_' because '_' is \w in RE2.

When sdrStep.PSUInW is available, prefer it over DCMI for

Delta is now SDR-to-SDR (sdrStep.PSUInW - sdrIdle.PSUInW) for
consistency. DCMI path kept as fallback when SDR has no PSU data.

MSI servers place PSU_POWER_IN/OUT sensors on entity 3.0, not 10.N
(the IPMI "Power Supply" entity). The old parser filtered by entity ID

Now delegates to collector.PSUSlotsFromSDR — the same name-based
matching already used in the Power Fit benchmark.

As metrics.db grew (1 sample/5 s × hours), handleMetricsChartSVG called
LoadAll() on every chart request — loading all rows across 4 tables through a
single SQLite connection. With ~10 charts auto-refreshing in parallel, requests
queued behind each other, saturating the connection pool and pegging a CPU core.
Fix: add a background compactor that runs every hour via the metrics collector:
• Downsample: rows older than 2 h are thinned to 1 per minute (keep MIN(ts)
per ts/60 bucket) — retains chart shape while cutting row count by ~92 %.
• Prune: rows older than 48 h are deleted entirely.
• After prune: WAL checkpoint/truncate to release disk space.
LoadAll() in handleMetricsChartSVG is unchanged — it now stays fast because
the DB is kept small rather than capping the query window.

Ramp step 1 reuses single-card calibration results (no extra run); steps
2..N run targeted_power on the growing GPU subset with derating active.
Remove OccupiedSlots/OccupiedSlotsNote fields and occupiedSlots() helper —
they were compensation for the old all-GPU calibration approach.

Previously each GPU was calibrated sequentially (one card fully done
before the next started), producing the staircase temperature pattern
seen on the graph.
Now all GPUs run together in a single dcgmi diag -r targeted_power
session per attempt. This means:
- All cards are under realistic thermal load at the same time.
- A single DCGM session handles the run — no resource-busy contention
from concurrent dcgmi processes.
- Binary search state (lo/hi) is tracked independently per GPU; each
card converges to its own highest stable power limit.
- Throttle counter polling covers all active GPUs in the shared ticker.
- Resource-busy exponential back-off is shared (one DCGM session).

Remove telemetry-guided initial candidate; use strict binary search
midpoint at every step. Clean and predictable convergence in O(log N)
attempts within the allowed power range [minLimitW, startingLimitW].

Power calibration previously stepped down 25 W at a time (linear),
requiring up to 6 attempts to find a stable limit within 150 W range.
New strategy:
- Binary search between minLimitW (lo, assumed stable floor) and the
starting/failed limit (hi, confirmed unstable), converging within a
10 W tolerance in ~4 attempts.
- For thermal throttle: the first-quarter telemetry rows estimate the
GPU's pre-throttle power draw. nextLimit = round5W(onset - 10 W) is
used as the initial candidate instead of the binary midpoint, landing
much closer to the true limit on the first step.
- On success: lo is updated and a higher level is tried (binary search
upward) until hi-lo ≤ tolerance, ensuring the highest stable limit is
found rather than the first stable one.
- Let targeted_power run to natural completion on throttle (no mid-run
SIGKILL) so nv-hostengine releases its diagnostic slot cleanly before
the next attempt.

During power calibration: if a thermal throttle (sw_thermal/hw_thermal)
causes ≥20% clock drop while server fans are below 98% P95 duty cycle,
record a CoolingWarning on the GPU result and emit an actionable finding
telling the operator to rerun with fans manually fixed at 100%.
During steady-state benchmark: same signal enriches the existing
thermal_limited finding with fan duty cycle and clock drift values.
Covers both the main benchmark (buildBenchmarkFindings) and the power
bench (NvidiaPowerBenchResult.Findings).

When a targeted_power attempt is cancelled (e.g. after sw_thermal
throttle), nv-hostengine holds the diagnostic slot asynchronously.
The next attempt immediately received DCGM_ST_IN_USE (exit 222)
and incorrectly derated the power limit.
Now: exit 222 is detected via isDCGMResourceBusy and triggers an
exponential back-off retry at the same power limit (1s, 2s, 4s, …
up to 256s). Once the back-off delay would exceed 300s the
calibration fails, indicating the slot is persistently held.

USB Export Drive:
lsblk reports TRAN only for whole disks, not partitions (/dev/sdc1).
Strip trailing partition digits to get parent disk before transport check.
LiveCD in RAM:
When RunInstallToRAM copies squashfs to /dev/shm/bee-live/ but bind-mount
of /run/live/medium fails (CD-ROM boots), /run/live/medium still shows the
CD-ROM fstype. Add fallback: if /dev/shm/bee-live/*.squashfs exists, the
data is in RAM — report status OK.
Dashboard Hardware Summary:
Show server Manufacturer + ProductName as heading and S/N as subline above
the component table, sourced from hw.Board (dmidecode system-type data).
Validate:
Remove Cycles input — always run once. cycles=1 hardcoded in runAllSAT().

NCCL all_reduce is always attempted when 2+ GPUs are selected; a failure
leaves InterconnectScore=0 (no bonus, no penalty) and OverallStatus
unaffected. Exposing the checkbox implied NCCL is optional and made a
failed run look like a deliberate skip.
- Remove benchmark-run-nccl checkbox and its change listener from pages.go
- Client sends run_nccl: selected.length > 1 (automatic)
- api.go default runNCCL=true is unchanged
- Selection note now mentions NCCL automatically for multi-GPU runs

- Add RampStep/RampTotal/RampRunID to NvidiaBenchmarkOptions, taskParams, and
NvidiaBenchmarkResult so ramp-up steps can be correlated across result.json files
- Add ScalabilityScore field to NvidiaBenchmarkResult (placeholder; computed externally
by comparing ramp-up step results sharing the same ramp_run_id)
- Propagate ramp fields through api.go (generates shared ramp_run_id at spawn time),
tasks.go handler, and benchmark.go result population
- Apply ServerPower penalty to CompositeScore when IPMI reporting_ratio < 0.75:
factor = ratio/0.75, applied per-GPU with a note explaining the reduction
- Add finding when server power delta exceeds GPU-reported sum by >25% (non-GPU draw)
- Report header now shows ramp step N/M and run ID instead of "parallel" when in ramp mode;
shows scalability_score when non-zero

When --query-gpu CSV fields fail (exit status 2 on some Blackwell +
driver combos), enrichGPUInfoWithMaxClocks now also parses from the
verbose nvidia-smi -q output already collected at benchmark start:
- Default Power Limit → DefaultPowerLimitW
- Current Power Limit → PowerLimitW (fallback)
- Multiprocessor Count → MultiprocessorCount
Fixes PowerSustainScore=0 on systems where all three CSV query
variants fail but nvidia-smi -q succeeds (confirmed on RTX PRO 6000
Blackwell + driver 590.48.01).

Before the per-GPU compute phases, run `dcgmi diag -r targeted_power`
for 45 s while collecting nvidia-smi power metrics in parallel.
The p95 power per GPU is stored as calibrated_peak_power_w and used
as the denominator for PowerSustainScore instead of the hardware default
limit, which bee-gpu-burn cannot reach because it is compute-only.
Fallback chain: calibrated peak → default limit → enforced limit.
If dcgmi is absent or the run fails, calibration is skipped silently.
Adjust composite score weights to match the new honest power reference:
base 0.35, thermal 0.25, stability 0.25, power 0.15, NCCL bonus 0.10.
Power weight reduced (0.20→0.15) because even with a calibrated reference
bee-gpu-burn reaches ~60-75% of TDP by design (no concurrent mem stress).
