No. The only reason I could imagine wanting to try this is if the 2 GPUs are different and one is slower.
If this is the case, you basically have to use them for different simulations. For parallel sims, because of the serial nature of Molecular Dynamics, a parallel job could very easily be slower than one run on the fastest GPU (since it will be waiting for the slowest one to finish).
