OK... For my edification, how "deep" into the GPU compute results does your proposal go? As in, would this be useful for catching unreliable GPUs (presumably, only after doing a second run, and not seeing the same residue)?

The question many will ask is it worthwhile to do this? A missed factor doesn't really impact GIMPS much (and certainly won't result in a missed MP). But I think there may be some interest in this ability (if it isn't too computationally expensive -- the second runs could be a random distribution).
