Hi HN, I built PantheonGPU because I wanted a better way to answer a simple question: is this GPU actually healthy and performing the way it should?A GPU can show normal temperatures and utilization and still be underperforming, unstable under certain workloads, or have memory, PCIe, or configuration issues.PantheonGPU actively tests the GPU instead of only monitoring telemetry. It currently includes 45+ tests covering compute, tensor workloads, memory, cache, PCIe, thermals, stability, and AI/LLM inference.It supports both NVIDIA CUDA and AMD ROCm.I’m also exploring a larger use case: running Pantheon across GPU fleets to identify individual GPUs that behave differently from the rest of a server or cluster.I’d especially appreciate feedback from people running AI infrastructure, multi-GPU systems, local LLMs, or GPU clouds.

Could you build this?
No Hardware diagnostics, PCIe bus saturation testing, and memory cell failure detection require low-level systems programming against CUDA and ROCm driver internals.
What it would actually take: Building this requires C/C++ or Rust directly interfacing with NVML, CUDA driver APIs, and ROCm SMI to execute low-level stress kernels, monitor hardware counters, and detect silent data corruption (SDC). The difficult part is writing custom GPU micro-benchmarks that intentionally stress memory controllers, clock domains, and thermal limits to catch hardware degradation. It demands deep systems engineering and GPU architecture expertise.
