I try to profile my application with pgprof 16.1.
When I run the application in order to generate a timeline, all I get is a warning: ‘Unable to read session timeline.’ - no timeline is shown. In the console there are multiple error messages: ‘fatal : Problem during SQL operation: unable to open database file’
These are the options I used:
- Profile current process only.
Start execution with profiling enabled
Enable concurrent kernel profiling
Enable CUDA API tracing in the timeline
Enable unified memory profiling
Enable OpenACC profiling
Run guided analysis
My ‘executable’ file is a *.ksh-script, that contains the actual executable:
time mpirun -np 1 prog_exe
