Yes, this will work.

Small addition: the hostgroup you would have to enter as "*@@mygroup"  
which is a little bit lengthy. I would suggest to attach a boolean  
complex like "bigio" to both queues - one time TRUE, one time FALSE.  
The default request could be coded in the "$SGE_ROOT/default/common/ 
sge_request" being "-l bigio=FALSE".

This means, only the IO itensive jobs must request "-l  
bigio" (boolean complexes have a default of TRUE when no value is
