Profiling a process launched by another process?
I am currently evaluating AQTime Pro for our needs here. In particular, I want to profile an application of ours that uses MPI (on only one process). The problem I have is that this executable cannot be started directly: it needs to be started through an MPI executable called 'mpirun.exe'. So, the command line equivalent would be 'mpirun -np 1 my_app.exe'.
I thought I could add 'my_app.exe' as a module to profile, and change the run parameters so that I could specify mpirun as the 'host' application and add the appropriate parameters. This actually results in AQTime successfully *launching* the application, but it does not profile it -- I get an empty results set.
Is it possible to do what I would like to do at all? What would be the correct way?
Thanks,
Charles Boivin
