Hi Jenny: You should be able to run both SGE and Torque at the same time (though I haven't tried it) since they are drastically different systems. The only thing to keep in mind is that they use similar binary names for commonly used programs like qsub and qstat, so make sure you know which one you're executing.
But it might be just as easy (and cleaner) to install Torque and SGE on different installations (machines), and then you can see their performance side by side.
