MPI on two machines with different choices of I_MPI_FABRICS

I am trying to run a simple "hello world" MPI program using two machines.

Here is the MPI program:

#include <mpi.h>
#include <stdio.h>

int main(int argc, char** argv) {
  MPI_Init(NULL, NULL);

  int world_size;
  MPI_Comm_size(MPI_COMM_WORLD, &world_size);

  int world_rank;
  MPI_Comm_rank(MPI_COMM_WORLD, &world_rank);

  char processor_name[MPI_MAX_PROCESSOR_NAME];
  int name_len;
  MPI_Get_processor_name(processor_name, &name_len);

  printf("Hello world from processor %s, rank %d out of %d processors\n",
         processor_name, world_rank, world_size);

  MPI_Finalize();
}

A few notes on my setup:

  • I am using Mellanox 3.18-2 OFED distribution, as directed by the Xeon Phi "MPSS user's guide"
  • For simplicity, I'm just trying to run MPI between two PC machines (no Xeon Phi involved)
  • Program is compiled using:
    mpiicpc helloMPI.cc -o helloMPI.XEON
  • Both machines are running bare-metal installations of CentOS 7 (i.e. no VMs)

I get different errors depending on some of the I_MPI_* environment variables.

The only configuration that works without any issues is:

export I_MPI_FABRICS=tcp
export I_MPI_MIC=1   # For some reason, I need this, even though I'm not running on a Xeon Phi
mpirun -ppn 1 -host 192.168.1.111,192.168.1.222 -np 2 ~/helloMPI.XEON

However, if I attempt to use other settings for I_MPI_FABRICS, then I get errors and it doesn't work.
For example, for the "dapl" fabric choice (which is my eventual desired setting):

export I_MPI_FABRICS=dapl
export I_MPI_MIC=1
mpirun -ppn 1 -host 192.168.1.111,192.168.1.222 -np 2 ~/helloMPI.XEON


 

host: 192.168.1.111
host: 192.168.1.222

I don't have access to the Intel MPI source code, so sadly I cannot figure out where exactly these errors are manifesting.

Let me know if there's any other information I can provide.
Cheers,

Dear James, could you please provide the outputs of "env | grep I_MPI" and the debug results when exporting I_MPI_DEBUG=6 under tcp/dapl/ofa fabrics. Thanks.

Although I do not have a fabric other than tcp, I find that if I omit setting I_MPI_FABRICS, that mpiexec appears to perform an ordered search using fastest fabrics to slowest fabric (tcp being last). Try removing the environment variable I_MPI_FABRICS and see what happens.
