Can WIEN2k use multiple nodes which do not share memory with each other

If you are talking about a situation where you are unable to use
passwordless login like Peter suggested, there is a way to do it.
It is not trivial (i.e. `echo PASSWORD | ssh ...´ does not work) because
`ssh´ tries to prevent this kind of thing because it is insecure; you
have to trick `ssh´ into thinking its input comes from a terminal. One
such solution is provided by `sshpass´:
<http://sourceforge.net/projects/sshpass/>.
Use this script with care, if you have to. If you can, use the proper
"ssh-keygen / ssh-copy-id" method.
