Oops sorry I made the test too fast: it still does not work properly with several logins:
I start on user1's machine: mpirun -np 2 --machinefile machinefile.txt MyProgram with machinefile: user1@machine1 slots=1 user2@machine2 slots=1 and I got : user1@machine2 password prompt ?! (there is no user1 account on machine2...) My problem is still open... why is there a connection attempt to machine2 with user1 ... Has somebody an explanation ?
