[Beowulf] gpu+server health monitoring -- ensure system cooling

Thank you each for the notes. The current host bios/bmc appears to read
data from a MIC card but not the Nvidia. I'm considering to find a
method to simply force an increased fan speed in the server for jobs
using the gpu. I'll also ask intel again if they can help, perhaps with
a custom sdr file. I assume they have done this on their current
generation of hardware which would hopefully be portable to a sandybrige
Are there published average running temperatures of gpu: k20, k40, k80?
nvidia-smi reported 66C during a few test jobs. This is below the power
throttle temperature on the gpu, but the utilization was still below 75%.
Thanks, I'll check for the ECC errors too.
