@BerkeleyLab researchers r improving the energy efficiency of #supercomputers & the infrastructures that support them

The Power Usage Effectiveness (PUE) metric has been used for years to determine how much of the power in a data center is consumed by the IT equipment (as opposed to other facility loads such as cooling and power distribution). However, this metric is not effective in determining the efficiency of computer equipment when the system’s cooling fans or power conversions are located outside of the computer itself. The working group developed two new metrics to help evaluate these situations: (1) ITUE (IT‑power usage effectiveness), which is similar to PUE but focuses on energy use inside the computer equipment, and (2) TUE (total-power usage effectiveness), which combines PUE and ITUE to provide a ratio of total energy (that of both internal and external support equipment) as well as the specific energy used in the HPC. The TUE can be used to compare one HPC system to another....
