Another option would be to provide side-by-side options so that people can transition at their leisure. SSH for those that want familiarity, and something like XCPU for those that want to actually use their big systems. Many LANL users eventually got used to our BProc systems, but we should have made the transition much smoother for them (e.g. run the system as lightweight BProc, but provide a full distro file system and start up sshd on each node). People don't expect to be able to ssh into individual cores, but they unfortunately don't tend to think of clusters the same way. Unless it is something like an Altix. -- Andrew Shewmaker
