-------------------------------------------------------------------------- WARNING: There are more than one active ports on host 'bms03', but the default subnet GID prefix was detected on more than one of these ports. If these ports are connected to different physical IB networks, this configuration will fail in Open MPI. This version of Open MPI requires that every physically separate IB subnet that is used between connected MPI processes must have different subnet ID values. Please see this FAQ entry for more details: http://www.open-mpi.org/faq/?category=openfabrics#ofa-default-subnet-gid NOTE: You can turn off this warning by setting the MCA parameter btl_openib_warn_default_gid_prefix to 0. -------------------------------------------------------------------------- -- started at 05/17/2019 20:57:00 -- mdtest-1.9.3 was launched with 260 total task(s) on 26 node(s) Command line used: /scratch1/leh015/io-500-dev/bin/mdtest "-C" "-t" "-F" "-w" "3901" "-e" "3901" "-d" "/scratch1/leh015/io-500-dev/datafiles/io500.2019.05.17-20.39.18/mdt_hard" "-n" "11500" "-x" "/scratch1/leh015/io-500-dev/datafiles/io500.2019.05.17-20.39.18/mdt_hard-stonewall" "-W" "0" Path: /scratch1/leh015/io-500-dev/datafiles/io500.2019.05.17-20.39.18 FS: 1117.6 TiB Used FS: 14.4% Inodes: 0.0 Mi Used Inodes: -nan% 260 tasks, 2990000 files [bss017:92838] 179 more processes have sent help message help-mpi-btl-openib.txt / default subnet prefix [bss017:92838] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages SUMMARY rate: (of 1 iterations) Operation Max Min Mean Std Dev --------- --- --- ---- ------- File creation : 9641.274 9641.237 9641.266 0.007 File stat : 0.000 0.000 0.000 0.000 File read : 0.000 0.000 0.000 0.000 File removal : 0.000 0.000 0.000 0.000 Tree creation : 562.922 562.922 562.922 0.000 Tree removal : 0.000 0.000 0.000 0.000 -- finished at 05/17/2019 21:02:11 --
