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.

Beowulfers,
Are any of you monitoring the power draw on your clusters? If so, can
any of you provide me with some statistics on your power draw under
heavy load? Ideally, I'm looking for the power load for a worst-case
scenario, such as running HPL, on a per-rack basis. If you can provide
me with the power draw and a description of the hardware, that would be
great.
I have some numbers from a friend who lurks on this list, but the more
data points I have, the better I can justify my power requirements for a
new cluster purchase I'm working on.
