HPC Power

As part of our reevaluation of our data center cooling capacity and overhaul, we need to get a handle on non-emergency power consumption in data center. This will be done by a third party consultant by clamping power cables in the penthouse of Excley. So I bought myself a metered PDU and have been busy plugging entire racks into it one at a time. I then measure “idle” and “peak” amperage consumption. The end picture should reveal how much Kw the HPC consumes of all non-emergency power (that is not on enterprise UPS). And we'll figure out how much Physical Plant spends supporting the HPC. Thanks PP!

In 2013 we found for our Dell Racks purchased in 2006 (full of PE1950 and PE2950 servers) Replace Dell Racks

So a great improvement in energy efficiency. We probably grew from near 5 teraflops to near 60 teraflops in this time period (double precision, floating point, theoretical).
