 # The D0 Cluster
-
+(this is modified text copied from http://d0.physi.uni-heidelberg.de/d0.html )
 --- 
 
  d0 cluster got his name from the first node, "d0". It was deployed during 2006. The original hardware has died, but was replaced with equivalent. It is still hosting login scripts, cluster monitoring, the batch system and GuestNet. But since it is less powerful then a modern phone and still runs SLC4 OS, it make no sense to use it interactively.
