Hi,

I'm a new user of openmpi, and I tried to run hello world in mpi but
get tons of warning during runing. I tried to go through the FAQ but
still could not figure out why these warnings happen. Could anyone
help to give me some hint?


Thanks a lot!

Best,
Zheng


I'm running openmpi on a opensuse linux of a two quad core machine.

=======Code ===========
#include "mpi.h"
#include <stdio.h>

int main( argc, argv )
int argc;
char **argv;
{
MPI_Init( &argc, &argv );
printf( "Hello world\n" );
MPI_Finalize();
return 0;
}

========Warnings during run time ========

Another transport will be used instead, although this may result in
