The nodes are outdated xeon but you have hundred of them. It uses a lot more electricity than a newer supercomputer but the hardware has been built so it may not be so bad for the environment to use it a few more years. The electricity bill is going to be much much cheaper than similarly sized clusters in the public cloud but still significant.

Would you turn around and pretend you never seen it, or do you have suggestions about some useful things that can be done with it?
