- Benchmark page now shows two result sections: Performance (scores) and
Power / Thermal Fit (slot table). After any benchmark task completes
the results section auto-refreshes via GET /api/benchmark/results
without a full page reload.
- Power results table shows each GPU slot with nominal TDP, achieved
stable power limit, and P95 observed power. Rows with derated cards
are highlighted amber so under-performing slots stand out at a glance.
Older runs are collapsed in a <details> summary.
- memtester is now wrapped with timeout(1) so a stuck memory controller
cannot cause Validate Memory to hang indefinitely. Wall-clock limit is
~2.5 min per 100 MB per pass plus a 2-minute buffer.

Phase 1 now calibrates each GPU individually (sequentially) so that
PowerRealizationPct reflects real degradation from neighbour thermals and
shared power rails. Previously the baseline came from an all-GPU-together
run, making realization always ≈100% at the final ramp step.
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].
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
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).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
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

- 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).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
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).

- BenchmarkHostConfig captures CPU model, sockets, cores, threads, and
total RAM from /proc/cpuinfo and /proc/meminfo at benchmark start.
- BenchmarkCPULoad samples host CPU utilisation every 10 s throughout
the GPU steady-state phase (sequential and parallel paths).
- Summarises avg/max/p95 and classifies status as ok / high / unstable.
- Adds a finding when CPU load is elevated (avg >20% or max >40%) or
erratic (stddev >12%), with a plain-English description in the report.

clocks.max.graphics / clocks.max.memory CSV fields return exit status 2 on
RTX PRO 6000 Blackwell (driver 98.x), causing the entire gpu inventory query
to fail and clock lock to be skipped → normalization: partial.
Fix:
- Add minimal fallback query (index,uuid,name,pci.bus_id,vbios_version,
power.limit) that succeeds even without clock fields
- Add enrichGPUInfoWithMaxClocks: parses "Max Clocks" section of
nvidia-smi -q verbose output to fill MaxGraphicsClockMHz /
MaxMemoryClockMHz when CSV fields fail
- Move nvidia-smi -q execution before queryBenchmarkGPUInfo so its output
is available for clock enrichment immediately after
- Tests: cover enrichment and skip-if-populated cases

HPL 2.3 from netlib compiled against OpenBLAS with a minimal
single-process MPI stub — no MPI package required in the ISO.
Matrix size is auto-sized to 80% of total RAM at runtime.
Build:
- VERSIONS: HPL_VERSION=2.3, HPL_SHA256=32c5c17d…
- build-hpl.sh: downloads HPL + OpenBLAS from Debian 12 repo,
compiles xhpl with a self-contained mpi_stub.c
- build.sh: step 80-hpl, injects xhpl + libopenblas into overlay
Runtime:
- bee-hpl: generates HPL.dat (N auto from /proc/meminfo, NB=256,
P=1 Q=1), runs xhpl, prints standard WR... Gflops output
- platform/hpl.go: RunHPL(), parses WR line → GFlops + PASSED/FAILED
- tasks.go: target "hpl"
- pages.go: LINPACK (HPL) card in validate/stress grid (stress-only)

- Replace diag level 1-4 dropdown with Validate/Stress radio buttons
- Validate: dcgmi L2, 60s CPU, 256MB/1p memtester, SMART short
- Stress: dcgmi L3 + targeted_stress in Run All, 30min CPU, 1GB/3p memtester, SMART long/NVMe extended
- Parallel GPU mode: spawn single task for all GPUs instead of splitting per model
- Benchmark table: per-GPU columns for sequential runs, server-wide column for parallel
- Benchmark report converted to Markdown with server model, GPU model, version in header; only steady-state charts
- Fix IPMI power parsing in benchmark (was looking for 'Current Power', correct field is 'Instantaneous power reading')

- bee-gpu-stress.c: remove per-wave cuCtxSynchronize barrier in both
cuBLASLt and PTX hot loops; sync at most once/sec so the GPU queue
stays continuously full — eliminates the CPU↔GPU ping-pong that
prevented reaching full TDP
- sat_fan_stress.go: default SizeMB 0 (auto = 95% VRAM) instead of
hardcoded 64 MB; tiny matrices caused <0.1 ms kernels where CPU
re-queue overhead dominated
- pages.go: move nvidia-targeted-power and nvidia-pulse from Burn →
Validate stress section alongside nvidia-targeted-stress; these are
DCGM pass/fail diagnostics, not sustained burn loads; remove the
Power Delivery / Power Budget card from Burn entirely

- Add parallel GPU mode (checkbox, off by default): runs all selected GPUs
simultaneously via a single bee-gpu-burn invocation instead of sequentially;
per-GPU telemetry, throttle counters, TOPS, and scoring are preserved
- Make queryBenchmarkGPUInfo resilient: falls back to a base field set when
extended fields (attribute.multiprocessor_count, power.default_limit) cause
exit status 2, preventing lgc normalization from being silently skipped
- Log explicit "graphics clock lock skipped" note when inventory is unavailable
- Collect server model from DMI (/sys/class/dmi/id/product_name) and store in
result JSON; benchmark history columns now show "Server Model (N× GPU Model)"
grouped by server+GPU type rather than individual GPU index

- Sample server power (IPMI dcmi) during baseline+steady phases in parallel;
compute delta vs GPU-reported sum; flag ratio < 0.75 as unreliable reporting
- Collect base_graphics_clock_mhz, multiprocessor_count, default_power_limit_w
from nvidia-smi alongside existing GPU info
- Add tops_per_sm_per_ghz efficiency metric (model-agnostic silicon quality signal)
- Flag when enforced power limit is below default TDP by >5%
- Add fp64 profile to bee-gpu-burn worker (CUDA_R_64F, CUBLAS_COMPUTE_64F, min cc 8.0)
- Improve Executive Summary: overall pass count, FAILED GPU finding
- Throttle counters now shown as % of steady window instead of raw microseconds
- bible-local: clock calibration research, H100/H200 spec, real-world GEMM baselines

bee-gpu-burn now receives --seconds <LoadSec> so it exits naturally
when the cycle ends, rather than relying solely on context cancellation
to kill it. Process group kill (Setpgid+Cancel) is kept as a safety net
for early cancellation (user stop, context timeout). Same fix for AMD
RVS which now gets duration_ms = LoadSec * 1000.

nvvs (DCGM validation suite) survives when dcgmi is killed mid-run,
leaving the GPU occupied. The next dcgmi diag invocation then fails
with "affected resource is in use".
Two-part fix:
- Add nvvs and dcgmi to KillTestWorkers patterns so they are cleaned
up by the global cancel handler
- Call KillTestWorkers at the start of RunNvidiaTargetedStressValidatePack
to clear any stale processes before dcgmi diag runs

bee-gpu-burn is a shell script that spawns bee-gpu-burn-worker children.
exec.CommandContext default cancel only kills the shell parent; the worker
processes survive and keep loading the GPU indefinitely.
Fix: set Setpgid=true and a custom Cancel that sends SIGKILL to the
entire process group (-pid), same pattern already used in runSATCommandCtx.
Applied to Nvidia, AMD, and CPU stress commands for consistency.
