Yes. Copy your ~/.ssh/id.pub to the server ~/.ssh/authorized_keys - it 
is done with this command:
  ssh-copy-id joe@example.com

then you will not be asked for a password, just as usual:
  ssh joe@example.com

You might want to have a pass-phrase on your local ~/.ssh/id and then 
use 'ssh-add' once when you boot your local machine, and you will 
only have to type your pass-phrase once every boot.

Maybe this should go into the parallel man page.
