Hi again,
I tried a simple mpi c++ program:

using namespace MPI;
using namespace std;
int main(int argc, char* argv[]) {
int rank,size;
Init(argc,argv);
rank=COMM_WORLD.Get_rank();
size=COMM_WORLD.Get_size();
rt will be used instead, although this may result in
lower performance.

However, as before the program does work in this special case, and I

Do these errors indicate a problem with the Open MPI installation?

Hi Jody,Indeed, all the nodes are running the same version of Open MPI. Perhaps I was incorrect to describe the cluster as heterogeneous. In fact, all the nodes run the same operating system (Scientific Linux 5.2), it's only the hardware that's different and even then they're all i386 or i686. I'm
Hi all,
First of all let me make it perfectly clear that I'm a complete
beginner as far as MPI is concerned, so this may well be a trivial
problem!
I've tried to set up Open MPI to use SSH to communicate between nodes
on a heterogeneous cluster. I've set up passwordless SSH and it seems
