when I use nvvp to profile my OpenACC application (PGI 15.7-15.10) it does not produce the typical timeline even though it is able to generate the required “raw data” (pressing the Examine GPU Usage button and looking at the Details tab I get a table with all kernel launches and timing data etc.). Initially I thought it was because my program still produces a memory error in the final destruction phase and nvvp warns about it. But when I put an exit(0) before that the program terminates normally and nvvp does not complain. However, still no timeline.
I have tried with nvvp from cuda 5.5 and 6.6 and PGI compiler version 15.7,15.9, and 15.10.
Is there any known incompatibility or am I doing something wrong?
