The local spool directories with the name of each node will be  
created automatically by SGE in the specified superior directory. You  
need just a directory like /var/spool/sge on all nodes to have it  
local, which will lower the NFS traffic in the end.

Sharing the $SGE_ROOT has the benefit, that an update is just  
necessary in one location - on the NFS-Server.
