Configuring your account for the cluster

• Setup your identity

  Setup single sign on throughout the cluster with the following commands:

  cd $HOME 
  ssh-keygen -t rsa1 -N ""  -f $HOME/.ssh/identity 
  ssh-keygen -t rsa -N "" -f $HOME/.ssh/id_rsa 
  ssh-keygen -t dsa -N "" -f $HOME/.ssh/id_dsa 
  cd .ssh 
  touch authorized_keys authorized_keys2 
  cat identity.pub >> authorized_keys 
  cat id_rsa.pub id_dsa.pub >> authorized_keys2 
  chmod 640 authorized_keys authorized_keys2
  		      

• Setup your path

  In your .cshrc, you may want to include the following in your path:

  # Use Chromium 
  set path = ( /opt/cr-1.7/bin/Linux $path ) 
  # Use Brook 
  set path = ( /opt/brookegpu-0.4/bin $path) 
  # Use MPI 
  set path = ( /opt/topspin/mpi/mpich/bin $path)
  		    

• Manage your password

  Never share your password and pick a strong password. To change it, use ssh to login to openlab.umiacs.umd.edu and run passwd. Be sure to limit your password to eight ascii characters.
