- 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

- 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
