Yes, this is to be expected. By default 'ssh' is used -- so as your user
it is trying to use ssh, which you do not have setup for password-less
login (and is required). You can try using 'rsh' as your own user by using
the "-rsh" flag:

mpirun_rsh -rsh -np 2 host1 host2 ./exec

Can you give this a try?

Thanks,

Matt
