Hello dear,
I’m currently tring to make some tests of calculation with CUDA. I have an ‘kernel launch failed with error [cudaErrorIllegalAddress]:“an illegal memory access was encountered”.’ error that I would want to debug, but I cannot make work cudamemcheck.exe.
There is my current configuration:
- Windows 10 64bits pro
- GTX 770
- Visual studio 2019 community
.\nvcc.exe --version
nvcc: NVIDIA (R) Cuda compiler driver

Then I’m trying to run cudamemcheck.exe with my program as executable is returning this error:
