Sure. But you will have to set up a load_sensor specific for your GPUs. And it would only allow a feedback to see that a particular gpu is fully loaded.

Why do they want to select a node by hand? With the complex gpu which you set up right now, SGE is aware and selecting an exechost where this resource is free. Checking the actual load (to be acquired by a load sensor) by visual inspection might give the impression that a node ist free, despite the fact that it's in a serial phase and the gpu usage may start soon. Then the node will become overloaded.
Having set up the consumable complex, should allow SGE to schedule the jobs without manual interference.
That a user requests a gpu and is not using it, can't be revised by a load sensor. Only by human negotiation. It's the same like someone requests a PE with 8 slots and starts only a serial computation.
