Nsight Compute profiling permission block
Three independent Nsight Compute profiles can expose the bottlenecks of the frozen T512-N32 baseline.
Diagnostic work, exact algebra and local capabilities are not treated as end-to-end mining advantage.
What was tested?
Three independent Nsight Compute profiles can expose the bottlenecks of the frozen T512-N32 baseline.
Why the test is meaningful
Hardware-counter profiling is useful only when the counters are actually collected; a successfully executed kernel with unavailable counters cannot support a profiling conclusion.
valid profile ⇔ kernel completes ∧ counters availableERR_NVGPUCTRPERM ⇒ environment-invalidno counters ⇒ no performance inferenceHow it was tested
Attempt the preregistered three-profile campaign against the frozen binary and stop immediately if the driver denies GPU counter access.
What happened
The kernel completed, but the driver returned ERR_NVGPUCTRPERM and Nsight exposed zero counters. The offered elevated-session path was cancelled and global permissions were not changed.
Exactness and statistical controls
The attempt is classified as environment-invalid, not positive or negative evidence about the kernel.
What the result means
No profiling conclusion can be drawn. Preserving the blocked run prevents permission failure from being misreported as a scientific result.
Limitations
- No counter data were collected.
- The profile was not repeated elevated.
- Static SASS analysis is a different experiment.
Evidence trail
Run the frozen command on a system where NVIDIA performance counters are explicitly authorized, without changing the binary or metrics.
