| Hello List,
|

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.
