Hi everyone:
Reducing power use has become an important topic. One of the questions I always wondered about is why more cluster do not turn off unused nodes. Slurm has hooks to turn nodes off when not in use and turn them on when resources are needed. My understanding is that power cycling creates temperature cycling, that then leads to premature node failure. Makes sense and has anyone ever studied/tested this ? The only other reason I can think of is that the delay in server boot time makes job starts slow or power surge issues. I'm curious about other ideas or experiences.
