My GPU is 1660TI, CUDA version is 10.1, Driver Version is 455.45.01, OS is Ubuntu 18.04
I input the code in my terminal
sudo /usr/local/cuda-10.1/NsightCompute-2019.1/nv-nsight-cu-cli --f ./test
the result is just like this:
==PROF== Connected to process 4835
==PROF== Profiling "matrix_add_2D" - 1: 0%....50%....100% - 3 passes
Success!
==PROF== Disconnected from process 4835
[4835] test@127.0.0.1
