Epic CUDA Debugging Fail

mike64_t · x · 2026-07-11

This is a technical rant about CUDA Graph and GPU driver compatibility issues. The root cause wasn't the driver itself, but rather an exceptionally bizarre API usage triggering an anomaly in the compatibility layer. Replies describe the situation as the CUDA Graph being so complex that node-level profiling directly triggers a Xid 43 error, leaving the GPU compromised for subsequent applications, with a warning that "things will only get worse."
