Debugging CUDA Graph Broke the GPU
mike64_t · x · 2026-07-11
The author recounts an absurd debugging experience with CUDA Graph, where the complexity caused node-level profiling to directly trigger a GPU Xid 43 error, leaving the GPU "poisoned" for all subsequent applications.
The takeaway is that these issues will only worsen, implying that troubleshooting and maintaining stability under complex CUDA or GPU workloads is becoming increasingly difficult.
