what you can find in Torque but not in SGE: request a mixture of  
nodes, i.e. one heavy node with much memory (or big I/O options) and  
5 nodes with less memory or less disk performance for a parallel job.

OTOH, if you have parallel jobs: http://www.beowulf.org/archive/2007- 

What is different between them from the idea: in Torque you submit a  
job into a queue, while in SGE you request resources and SGE will  
select an appropriate queue for you.
