You need to setup passwordless ssh between the nodes. Please see the README for more instructions.
Hello! When I try to exec my program on several machines, there is some trouble:
When I use one node, there is all right. Before starting, system ask me:
mpiu@ub1's password: ...
But, when I try with two nodes:
mpiu@ub2's password: mpiu@ub1's password: ...
On one line! I try to typewrite password, but there is just stop and don't work. Without any issues or errors messages.
I use mpich 1.4.1 and Ubuntu 12.
