- You have to be a member of one of the 29 projects that may compute on Palma
In this case, the user can be registered in
myJAM. Here you also find an overview of the queues.
Another tool for a graphical view of the queues is pbstop-
The node for a worldwise ssh-Login is called palma.uni-muenster.de. If you wand to have a graphical login, you can use the
login via vnc
