Hi Team,
I’m a beginner with CUDA, and I just got an error when I use NVPROF but I don’t know why.
Several days ago when I used only one GPU device, nvprof works fine. And the hardware and software didn’t change these days. I’m wondering what should I do if I hope use nvprof to profile the application. Thanks very much!
I used pgf90 (CUDA Fortran) with -Mcuda.
==22439== NVPROF is profiling process 22439, command: ./Xvicar3dPAT-2.4.0
======== Profiling result:
No kernels were profiled.
No API activities were profiled.
======== Error: incompatible CUDA driver version.
