-------------------------------------------------------------------------- WARNING: There are more than one active ports on host 'bss018', 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. -------------------------------------------------------------------------- IOR-3.2.0: MPI Coordinated Test of Parallel I/O Began : Tue May 21 23:28:48 2019 Command line : /scratch1/leh015/io-500-dev/bin/ior -w -C -Q 1 -g -G 27 -k -e -t 47008 -b 47008 -s 110000 -o /scratch1/leh015/io-500-dev/datafiles/io500.2019.05.21-23.18.14/ior_hard/IOR_file -O stoneWallingStatusFile=/scratch1/leh015/io-500-dev/datafiles/io500.2019.05.21-23.18.14/ior_hard/stonewall -O stoneWallingWearOut=1 -D 0 Machine : Linux bss018 TestID : 0 StartTime : Tue May 21 23:28:48 2019 Path : /scratch1/leh015/io-500-dev/datafiles/io500.2019.05.21-23.18.14/ior_hard FS : 1117.6 TiB Used FS: 9.8% Inodes: 0.0 Mi Used Inodes: -nan% Options: api : POSIX apiVersion : test filename : /scratch1/leh015/io-500-dev/datafiles/io500.2019.05.21-23.18.14/ior_hard/IOR_file access : single-shared-file type : independent segments : 110000 ordering in a file : sequential ordering inter file : constant task offset task offset : 1 tasks : 160 clients per node : 16 repetitions : 1 xfersize : 47008 bytes blocksize : 47008 bytes aggregate filesize : 770.52 GiB Results: access bw(MiB/s) block(KiB) xfer(KiB) open(s) wr/rd(s) close(s) total(s) iter ------ --------- ---------- --------- -------- -------- -------- -------- ---- [bss017:127153] 159 more processes have sent help message help-mpi-btl-openib.txt / default subnet prefix [bss017:127153] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages stonewalling pairs accessed min: 110000 max: 110000 -- min data: 4.8 GiB mean data: 4.8 GiB time: 313.6s write 2511.63 45.91 45.91 0.138069 313.98 0.028703 314.14 0 Max Write: 2511.63 MiB/sec (2633.63 MB/sec) Summary of all tests: Operation Max(MiB) Min(MiB) Mean(MiB) StdDev Max(OPs) Min(OPs) Mean(OPs) StdDev Mean(s) Test# #Tasks tPN reps fPP reord reordoff reordrand seed segcnt blksiz xsize aggs(MiB) API RefNum write 2511.63 2511.63 2511.63 0.00 56025.18 56025.18 56025.18 0.00 314.14443 0 160 16 1 0 1 1 0 0 110000 47008 47008 789013.7 POSIX 0 Finished : Tue May 21 23:34:02 2019
