vtune hardware event-based sampling for mpi app

$

I am trying to use vtune to analyze an mpi program which is a mixture of python, c and fortran. I am able to do hotspots collection for this program just fine, but when I try to do advanced hotspots or snb-general-exploration it hangs.

I run with

mpirun -np 1 -l amplxe-cl -collect snb-general-exploration --result-dir appge -- python <...args...> : -np 7 python <...args...>

I'm running on a single node with 16 cores for now but would like to do this analysis for larger cases on multiple nodes. Compiler version is 14.0.2.

I am able to run a "hello world" mpi application written in c with the snb-general-exploration or advanced-hotspots collection using a command similar to what I'm trying to use with the python/c/fortran app, so it is not an issue with sampling drivers.

Any ideas how to get this to work? Thanks in advance.
