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_at_machine1 slots=1
user2_at_machine2 slots=1
and I got :
user1_at_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 ?
Thanks,
Olivier
