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).

- 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.

Adds a new checkbox (enabled by default) in the benchmark section.
In ramp-up mode N tasks are spawned simultaneously: 1 GPU, then 2,
then 3, up to all selected GPUs — each step runs its GPUs in parallel.
NCCL runs only on the final step.

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

Two issues:
1. BMC/management VGA chips (e.g. Huawei iBMC Hi171x, ASPEED) were included
in GPU inventory because shouldIncludePCIeDevice only checked the PCI class,
not the device name. Added a name-based filter for known BMC/management
patterns when the class is VGA/display/3d.
2. New NVIDIA GPUs (e.g. RTX PRO 6000 Blackwell, device ID 2bb5) showed as
"Device 2bb5" because lspci's database lags behind. Added "name" to the
nvidia-smi query and use it to override dev.Model during enrichment.

- Runtime Health now shows only LiveCD system status (services, tools,
drivers, network, CUDA/ROCm) — hardware component rows removed
- Hardware Summary now shows server components with readable descriptions
(model, count×size) and component-status.json health badges
- Add Network Adapters row to Hardware Summary
- SFP module static info (vendor, PN, SN, connector, type, wavelength)
now collected via ethtool -m regardless of carrier state
- PSU statuses from IPMI audit written to component-status.json so PSU
badge shows actual status after first audit instead of UNKNOWN

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')

Adds a "Multi-GPU tests — use all GPUs" checkbox to the NVIDIA GPU
selector (checked by default). When enabled, PSU Pulse, NCCL, and
NVBandwidth tests run on every GPU in the system regardless of the
per-GPU selection above — which is required for correct PSU stress
testing (synchronous pulses across all GPUs create worst-case
transients). When unchecked, only the manually selected GPUs are used.
The same logic applies both to Run All (expandSATTarget) and to the
individual Run button on each multi-GPU test card.

pulse_test is a PSU/power-delivery test, not a per-GPU compute test.
Its purpose is to synchronously pulse all GPUs between idle and full
load to create worst-case transient spikes on the power supply.
Running it one GPU at a time would produce a fraction of the PSU load
and miss any PSU-level failures.
- Move nvidia-pulse from nvidiaPerGPUTargets to nvidiaAllGPUTargets
(same dispatch path as NCCL and NVBandwidth)
- Change card onclick to runNvidiaFabricValidate (all selected GPUs at once)
- Update card title to "NVIDIA PSU Pulse Test" and description to
explain why synchronous multi-GPU execution is required

nvidia-interconnect (NCCL all_reduce_perf) and nvidia-bandwidth
(NVBandwidth) verify fabric connectivity and bandwidth — they are
not sustained burn loads. Move both from the Burn section to the
Validate section under the stress-mode toggle, alongside the other
DCGM diagnostic tests moved in the previous commit.
- Add sat-card-nvidia-interconnect and sat-card-nvidia-bandwidth
validate cards (stress-only, all selected GPUs at once)
- Add runNvidiaFabricValidate() for all-GPU-at-once dispatch
- Add nvidiaAllGPUTargets handling in expandSATTarget/runAllSAT
- Remove Interconnect / Bandwidth card from Burn section
- Remove nvidia-interconnect and nvidia-bandwidth from runAllBurnTasks
and the gpu/tools availability map

- 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

losetup --replace --direct-io=on fails with EINVAL when the target file
