We have an MPI application (written in C) and are interested in profiling just one section of the code. We have successfully used VTune Pause/Resume to analize these sections of our code when running multithreaded on one processor. When we try to use two MPI processes, no profile data is generated. Is Pause/Resume supported for MPI applications?
Running on CentOS 6.3 using Intel(R) VTune(TM) Amplifier XE 2013 (build 253325). App is compiled with icc.
