Ok, sorry. Here is the details:
---
hello.c
---
#include <mpi.h>
#include <stdio.h>
#include <sys/utsname.h>
int main(int argc, char **argv)
{
int myrank;
struct utsname unam;
MPI_Init(&argc, &argv);
uname(&unam);
MPI_Comm_rank(MPI_COMM_WORLD, &myrank);
printf("Hello from rank %d on host %s\n", myrank, unam.nodename);
MPI_Finalize();
}
---
srun -N 4 ./hello
Hello from rank 0 on host A14
Hello from rank 0 on host A12
Hello from rank 0 on host A13
Hello from rank 0 on host A11
