mpich using ssh

[Jon Tegner]

Hello,

As I understand it (haven't tried yet) a file
($HOME/.ssh/autorized_keys) containing the public keys for every node in

the cluster has to exist on every node AND for every user. Is this
correct? And is there an easy way to generate this file?

Would it be easier to instead use kerberos (in which case I guess one
needs a server separated from the cluster)?

Thanks!
