bf6ecab4f0 Add per-precision benchmark phases, weighted TOPS scoring, and ECC tracking
- Split steady window into 6 equal slots: fp8/fp16/fp32/fp64/fp4 + combined
- Each precision phase runs bee-gpu-burn with --precision filter so PowerCVPct reflects single-kernel stability (not round-robin artifact)
- Add fp4 support in bee-gpu-stress.c for Blackwell (cc>=100) via existing CUDA_R_4F_E2M1 guard
- Weighted TOPS: fp64×2.0, fp32×1.0, fp16×0.5, fp8×0.25, fp4×0.125
- SyntheticScore = sum of weighted TOPS from per-precision phases
- MixedScore = sum from combined phase; MixedEfficiency = Mixed/Synthetic
- ComputeScore = SyntheticScore × (1 + MixedEfficiency × 0.3)
- ECC volatile counters sampled before/after each phase and overall
- DegradationReasons: ecc_uncorrected_errors, ecc_corrected_errors
- Report: per-precision stability table with ECC columns, methodology section
- Ramp-up history table redesign: GPU indices as columns, runs as rows

02e44b1172 Fix USB/RAM status checks; add server model+S/N to dashboard; remove cycles
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().

813e2f86a9 Add scalability/ramp-up labeling, ServerPower penalty in scoring, and report improvements
- 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

58a6da9b44 Recover power limits and SM count from nvidia-smi -q in enrichGPUInfo
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).

f4a19c0a00 Add power calibration step to benchmark; fix PowerSustainScore reference
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).

9e3dcf9b4d Record host CPU/RAM config in benchmark results; check CPU load
- 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.

525ed8b8fc Fix GPU clock lock normalization for Blackwell (clocks.max.* unsupported)
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

e0d94d7f47 Remove HPL from build and audit flows 2026-04-08 10:00:23 +03:00
16e7ae00e7 Add HPL (LINPACK) benchmark as validate/stress task
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)

b2f8626fee Refactor validate modes, fix benchmark report and IPMI power
- 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')

d1a22d782d Move power diag tests to validate/stress; fix GPU burn power saturation
- 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

93cfa78e8c Benchmark: parallel GPU mode, resilient inventory query, server model in results
- 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

  with NVreg_EnableGpuFirmware=0. Handles EBUSY case with clear error.
- Write /run/bee-nvidia-mode (gsp-on/gsp-off/gsp-stuck) for audit layer
- Show GSP mode badge in sidebar: yellow for gsp-off, red for gsp-stuck
- Report NvidiaGSPMode in RuntimeHealth with issue entries
- Simplify GRUB menu: default (KMS+GSP), advanced submenu (GSP=off,
  nomodeset, fail-safe), remove load-to-RAM entry
- Add pcmanfm, ristretto, mupdf, mousepad to desktop packages

19b4803ec7 Pass exact cycle duration to GPU stress instead of 86400s sentinel
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.

1bdfb1e9ca Fix nvidia-targeted-stress failing with DCGM_ST_IN_USE (-34)
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

c5d6b30177 Fix platform thermal cycling leaving GPU load running after test ends
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.

1f750d3edd fix(webui): prevent orphaned workers on restart, reduce metrics polling, add Kill Workers button
- tasks: mark TaskRunning tasks as TaskFailed on bee-web restart instead of
  re-queueing them — prevents duplicate gpu-burn-worker spawns when bee-web
  crashes mid-test (each restart was launching a new set of 8 workers on top
  of still-alive orphans from the previous crash)
- server: reduce metrics collector interval 1s→5s, grow ring buffer to 360
  samples (30 min); cuts nvidia-smi/ipmitool/sensors subprocess rate by 5×
- platform: add KillTestWorkers() — scans /proc and SIGKILLs bee-gpu-burn,
  stress-ng, stressapptest, memtester without relying on pkill/killall
- webui: add "Kill Workers" button next to Cancel All; calls
  POST /api/tasks/kill-workers which cancels the task queue then kills
  orphaned OS-level processes; shows toast with killed count
- metricsdb: sort GPU indices and fan/temp names after map iteration to fix
  non-deterministic sample reconstruction order (flaky test)
- server: fix chartYAxisNumber to use one decimal place for 1000–9999
  (e.g. "1,7к" instead of "2к") so Y-axis ticks are distinguishable

- Compute Stress: checkboxes for cpu/memory-stress/stressapptest
- Platform Thermal Cycling: component checkboxes (cpu/nvidia/amd)

- bee-gpu-burn: default size-mb changed from 64 to 0 (auto); script
  now queries nvidia-smi memory.total per GPU and uses 95% of it
