I have been trying to collect mpi statistics of my application and have been using the following settings
export I_MPI_STATS=ipm
export I_MPI_STATS_SCOPE="all2all;all2one;one2all;comm;io;sync;time"
################################################################################
#
# command : ./test.exe (completed)
# host : asn5/x86_64_Linux mpi_tasks : 16 on 1 nodes
# start : 01/01/15/10:47:28 wallclock : 52.170432 sec
# stop : 01/01/15/10:48:20 %comm : 36.61
# gbytes : 0.00000e+00 total gflop/sec : NA

# %comm 36.6135 12.0343 43.8415
# gflop/sec NA NA NA NA
# gbytes 0 0 0 0
#
#
As it can been seen from the above output, the values of gbytes and gflop/sec are missing.
What needs to be done inorder to get the values of gbytes & gflop/sec ??
