I am trying to use ompi-server with Open MPI 1.10.6. I'm wondering if I
should run this with or without the mpirun command. If I run this:
ompi-server --no-daemonize -r +
It prints something such as 959315968.0;tcp://172.31.3.57:45743 to stdout
but I have thus far been unable to connect to it. That is, in another
application on another machine which is on the same network as the
ompi-server machine, I try
MPI_Info info;
MPI_Info_create(&info);
MPI_Info_set(info, "ompi_global_scope", "true");
char myport[MPI_MAX_PORT_NAME];
MPI_Open_port(MPI_INFO_NULL, myport);
MPI_Publish_name("adam-server", info, myport);
But the MPI_Publish_name() function hangs forever when I run it like
mpirun -np 1 --ompi-server "959315968.0;tcp://172.31.3.57:45743" server
Blog posts are inconsistent as to if you should run ompi-server with mpirun
or not so I tried using it but this seg faults:
mpirun -np 1 ompi-server --no-daemonize -r +

Am I doing something wrong?
