When I run executable under Nsight Systems 2019.5.2 it is doing nothing. So its console is empty, CPU is free. Executable is matrix multiplication sample from CUDA 10.2 with tiny changes, built with Visual Studio 2019, release mode. If I stop profiling after a couple of minutes, I get
Process ID Name Arguments CPU utilization
10480 matrixMul72.exe 60,15%
9356 conhost.exe 39,85%
Process ID Module name Address CPU time (overall) CPU time (per process)
10480 C:\Windows\System32\nvapi64.dll [unknown] 44,73% 74,36%
9356 C:\Windows\System32\win32u.dll [unknown] 28,02% 70,32%
10480 C:\Windows\System32\ntdll.dll [unknown] 14,14% 23,50%
So no CUDA kernels execution trails.
Tried with default settings and with several parameters changed with the same effect.
