Ask HN: I have access to NVIDIA GPUs: 2x K80s, 1x K40... what should I do?

Just as the title says, I have access to 2 NVIDIA Tesla K80s and one NVIDIA Tesla K40. These GPUs were used for about a years worth of experiments and research, and those experiments are over for the time being. 1. Is there a way to help "the greater good" with them? 2. If you had access to them, what would you do?
