I'm using NVIDIA Nsight Systems cli (nsys) to profile a simple cuda program (vectors adding). I've already checked the documentation but I think I'm missing something.
I'm running the nsys profile command with --stats=true flag.
CUDA API Statistics:
Time(%) Total Time (ns) Num Calls Average Minimum Maximum Name
------- --------------- --------- ------------ ---------- ---------- ---------------------
CUDA Kernel Statistics:
Time(%) Total Time (ns) Instances Average Minimum Maximum Name
And this is what I'm getting back (values omitted). Should I enable a certain flag to show memory statistics?
tested with the --trace=cuda flag but again no memory statistics
Is this a compatibility problem between Windows and Cuda should I downgrade? I really don't know. When I run the same command in Ubuntu is working properly. It's really driving me crazy.
Any help is welcome Thanks
The memory operation statistics you are referring to track unified memory (UM) demand-paged transfer activity.
The UM model on windows does not used demand-paged transfer of data, so you won't see these sections on windows.
