Show HN: Utilyze – an open source GPU monitoring tool more accurate than nvtop

Systalyze open-sourced Utilyze to measure real GPU compute efficiency in production, with negligible overhead claimed. The post says nvidia-smi and nvtop only check whether any kernel runs during the sampling window; an H100 has 132 SMs and 17,424 cores. The key issue is real throughput headroom, not binary utilization dashboards.

Why it matters: HKR-H/K/R all pass: the hook is sharp, the post explains the sampling flaw, and GPU waste is a real practitioner nerve. Unknown vendor and single-tool scope keep it in the 72–77 band.
