I know in SGE 5.3 sge_execd would look at the hostname that the compute 
node thinks it has (what you get if you run 'hostname' on the box).  It 
would then send that string to sge_qmaster and used that to match the 
box to an exec host entry in SGE.   I'm not sure if it still does that 
in SGE 6.0 or not.
