Subject: [OMPI users] Tons of warnings in running my first openmpi job
From: Zheng Li (iamzhengli_at_[hidden])
Date: 2009-12-05 23:17:10


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 ========
