Consider the bandwidthTest example from CUDA samples. It works as expected when compiled and launched normally.
$ /usr/local/cuda-12.3/bin/nvcc bandwidthTest.cu -o bandwidthTest
$ ./bandwidthTest

NOTE: The CUDA Samples are not meant for performance measurements. Results may vary when GPU Boost is enabled.
However, it doesn’t work under Nsight Compute. Note that I have to use a standalone install of Nsight Compute 2019.5 because it’s the last version that supports Tesla P40 GPUs.

How do I fix this so that I can instrument my code with nv-nsight-cu-cli
?
