Hi All,

I am wondering whether there is any mechanism to automatically
power down nodes (e.g., ACPI S3) when idle for some time, and
automatically wake up when requested (e.g., by WOL, some cluster
scheduler, ssh). I imagine that I could cut down power & cooling
on our system by more than 50%. Any hints?

Thanks, Frithjof
