Hi. I’m trying to analyze my application accelerated using OpenACC with NVIDIA Visual Profiler (NVVP). To launch the analysis, after I’ve opened the GUI, I select File → New Session → I enter the executable file location → Next ->Finish.
After the execution is completed an alert appears saying “The start and end timestamps on 12 kernels, memcpys, and other collected profile data are invalid. Those profiling records have beem dropped and will not be displayed in the timeline”.
The application without the profiler runs correctly and by calling nvidia-smi during its execution we notice that it is correctly offloaded on the GPU.
Is there any way to fix this situation? It happens on every accelerated app that I try to analyze. Thanks in advance.
