I am running some performance tests (Open SpeedShop) with a program which uses Open MPI and Infiniband.
I see a line of code which appears to be taking a considerable amount of cpu time in relation to other pieces of the code.
opal_paffinity_base_get_physical_socket_id (libmpi.so.1.0.8: paffinity_base_wrappers.c,118)
Exclusive CPU time in seconds.

Is this normal behavior?
