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. % of CPU Time Statement Location (Line Number) 19031.94 38.339796 paffinity_base_wrappers.c(118) 14188.66 28.583021 paffinity_base_wrappers.c(113) 10934.38 22.027282 paffinity_base_wrappers.c(129) 2185.16 4.401999 paffinity_base_wrappers.c(121) 1081.96 2.179606 paffinity_base_wrappers.c(130) 546.93 1.101789 paffinity_base_wrappers.c(114) 546.17 1.100258 paffinity_base_wrappers.c(65) 541.67 1.091193 paffinity_base_wrappers.c(126) 540.52 1.088876 ompi_mpi_abort.c(80) 2.23 0.004492 ompi_mpi_abort.c(101) Is this normal behavior?
