[Beowulf] Power draw of cluster nodes under heavy load

Power draw will vary greatly depending on many factors.  Where I am at 
we currently have 16 racks of HPC equipment (compute nodes, storage, 
network gear, etc.) using about 140kVA but can use up to 160 kVA.  A 
single rack with 26 compute nodes each with 64 cores worth of AMD 6276 
(Supermicro boxes) is using about 18 kW across the PDUs, 3 phase at 240 
volts, with most of the nodes at 100% CPU usage.
