Thanks. It looks like mpiexec thinks that all four nodes are local nodes, which is a bug that was fixed after 1.4.1p1 was released. Can you try the mpiexec from 1.5b1:<br>

You don't need to recompile the application. Just run it with this new mpiexec.<span class="HOEnZb"><font color="#888888"><br>
