You cannot accelerate this in the way you are thinking, the reason the GPUs are not working with the short masks is because there's nothing for them to be doing. There isn't enough work to feed them. This is a common misconception/failure point when people try to use large GPU rigs. More GPUs is not always faster, and in many cases it can be slower or much harder to actually utilize.
