| Hello List,
|

attached script phello.sh

Works for me (though I prefer salloc), suggesting that you did something to
your network topology or Open MPI configuration:

:~$ cat /tmp/jerome_hw.c
// mpicc -o phello phello.c
// mpirun -np 5 phello

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

int main(int narg, char *args[]){
  int rank,size;
        char ProcessorName[MPI_MAX_PROCESSOR_NAME];
        int ProcessorNameLength;

  MPI_Init(&narg,&args);

  MPI_Comm_rank(MPI_COMM_WORLD,&rank);
  MPI_Comm_size(MPI_COMM_WORLD,&size);

        MPI_Get_processor_name(ProcessorName,&ProcessorNameLength);
        sleep(11);
        fprintf(stdout,
                        "Hello world! I am %d of %d and my name is `%s'\n",
                rank,size,
                ProcessorName);

  MPI_Finalize();

  return 0; }

//
// End of file `phello.c'.

:~$ mpicc.openmpi -o /tmp/jerome_hw /tmp/jerome_hw.c
:~$ orterun -np 2 /tmp/jerome_hw
Hello world! I am 1 of 2 and my name is `xyz-1'
Hello world! I am 0 of 2 and my name is `xyz-1'
:~$ salloc orterun -np 2 /tmp/jerome_hw
salloc: Granted job allocation 421
Hello world! I am 0 of 2 and my name is `xyz-1'
Hello world! I am 1 of 2 and my name is `xyz-1'
salloc: Relinquishing job allocation 421
:~$

Try simplifying further: no default hosts beside localhost etc.  Try orterun
before you try salloc.  Simplicity first.
