I am a new comer to Open MPI.
I have spent the last day trying to diagnose why a "hello world" MPI application compiled with OpenMPI v1.6.1 (64 bit) hangs when run on two EC2 Windows instances. I note they are running on different subnets so I'm using the mca btl_tcp_if_include 10.0.0.0/8 parameter. My two hosts are 10.242.73.81,10.116.114.238. I've placed the executable in the same path on both machines. Diagnostic info requested is attached along with sample application source. When I run two processes on one instance - the command succeeds: C:\mpi\exe>mpiexec -n 2 -host 10.242.73.81 --mca btl_tcp_if_include 10.0.0.0/8 MPIHello.exe WE have 2 processors Hello 1 Processor 1 at node AMAZONA-BMCKVD6 reporting for duty When I run across two hosts, the executable is launched on both instances but the process hangs: C:\mpi\exe>mpiexec -n 4 -host 10.242.73.81,10.116.114.238 --mca btl_tcp_if_include 10.0.0.0/8 MPIHello.exe connecting to 10.116.114.238 username:greenbutton password:********* Save Credential?(Y/N) n WE have 4 processors Re-running with debug: C:\mpi\exe>mpiexec -n 4 -host 10.242.73.81,10.116.114.238 -d --mca btl_tcp_if_include 10.0.0.0/8 MPIHello.exe [AMAZONA-BMCKVD6:01240] procdir: C:\Users\GREENB~1\AppData\Local\Temp\2\openmpi-sessions-greenbutton@AMAZONA- BMCKVD6_0\63746\0\0 [AMAZONA-BMCKVD6:01240] jobdir: C:\Users\GREENB~1\AppData\Local\Temp\2\openmpi-sessions-greenbutton@AMAZONA- BMCKVD6_0\63746\0 [AMAZONA-BMCKVD6:01240] top: openmpi-sessions-greenbutton@AMAZONA-BMCKVD6_0 [AMAZONA-BMCKVD6:01240] tmp: C:\Users\GREENB~1\AppData\Local\Temp\2 [AMAZONA-BMCKVD6:01240] mpiexec: reset PATH: C:\Program Files (x86)\OpenMPI_v1.6-x64\bin;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\Sy stem32\WindowsPowerShell\v1.0\; [AMAZONA-BMCKVD6:01240] mpiexec: reset LD_LIBRARY_PATH: C:\Program Files (x86)\OpenMPI_v1.6-x64\lib connecting to 10.116.114.238 username:greenbutton password:********* Save Credential?(Y/N) n [AMAZONA-BMCKVD6:02728] procdir: C:\Users\GREENB~1\AppData\Local\Temp\2\openmpi-sessions-greenbutton@AMAZONA- BMCKVD6_0\63746\1\0 [AMAZONA-BMCKVD6:02728] jobdir: C:\Users\GREENB~1\AppData\Local\Temp\2\openmpi-sessions-greenbutton@AMAZONA- BMCKVD6_0\63746\1 [AMAZONA-BMCKVD6:02728] top: openmpi-sessions-greenbutton@AMAZONA-BMCKVD6_0 [AMAZONA-BMCKVD6:02728] tmp: C:\Users\GREENB~1\AppData\Local\Temp\2 [AMAZONA-BMCKVD6:02728] [[63746,1],0] node[0].name AMAZONA-BMCKVD6 daemon 0 [AMAZONA-BMCKVD6:02728] [[63746,1],0] node[1].name 10 daemon 1 [AMAZONA-BMCKVD6:01500] procdir: C:\Users\GREENB~1\AppData\Local\Temp\2\openmpi-sessions-greenbutton@AMAZONA- BMCKVD6_0\63746\1\2 [AMAZONA-BMCKVD6:01500] jobdir: C:\Users\GREENB~1\AppData\Local\Temp\2\openmpi-sessions-greenbutton@AMAZONA- BMCKVD6_0\63746\1 [AMAZONA-BMCKVD6:01500] top: openmpi-sessions-greenbutton@AMAZONA-BMCKVD6_0 [AMAZONA-BMCKVD6:01500] tmp: C:\Users\GREENB~1\AppData\Local\Temp\2 [AMAZONA-BMCKVD6:01500] [[63746,1],2] node[0].name AMAZONA-BMCKVD6 daemon 0 [AMAZONA-BMCKVD6:01500] [[63746,1],2] node[1].name 10 daemon 1 WE have 4 processors I'd appreciate any guidance to getting this example to run on two instances on disparate subnets on Windows Server 2008 R2.
