Hi Reuti and Chris,

First of all, thanks for your answer.

No, we are not sharing the $SGE_ROOT between both clusters, they are 
different installations, and they are installed in different paths, and 
besides they are different versions, one is installed with *SGE 6.0u6* 
and the other one with *GE 6.1u3*

In this moments, the $SGE_CELL is "default" in both clusters. How to 
should I configure it?

The sge_qmaster/sge_execd ports are not the same in both clusters, 
should they are the same?

Yes, same user accounts exist in both cluster, but /home is not shared.

Sorry, how can I select a different cellname with qstat?

Ok, I have to read this.
