Writing MPI programs II

Another Example (Again no messsage-passing) ( hello1.c):

    1 #include <stdio.h> 
    2 #include <mpi.h> 
    3 
    4 int main(argc, argv) 
    5 int argc; 
    6 char *argv[]; 
    7 {
    8     char name[BUFSIZ]; 
    9     int length; 
   10     MPI_Init(&argc, &argv); 
   11     MPI_Get_processor_name(name, &length); 
   12     printf("%s: hello world\n", name); 
   13     MPI_Finalize(); 
   14 }
