CREATE HPC statistics¶

Node information¶

Data on CREATE HPC nodes (number of cores and GPUs, amount of memory) is available to download as a .csv file.

Power usage effectiveness¶

Power usage effectiveness (PUE) of a data centre is a measure of how efficiently a data centre uses energy. Specifically, it describes how much energy is used directly by computing equipment vs. other requirements such as lighting and cooling. An ideal PUE of 1.0 would mean that all energy is used directly by computing equipment.

CREATE HPC hardware is spread across several data centres. The PUE for these data centres in 2024 was:

Location 1: 1.23-1.38 (mean: 1.33)
Location 2: 1.23-1.7 (mean: 1.57)
Location 3: 1.29-1.54 (mean: 1.37)

Most of our active HPC hardware is located in Location 3. The estimated energy usage for these locations in 2024 was:

Location 1: power monitoring not available
Location 2: 273 MWh
Location 3: 758 MWh

Hardware purchasing and disposal¶

Researchers who wish to purchase dedicated compute or storage for specific research projects are encouraged to do this via e-Research. Details about costing compute and storage for grant applications, as well as current server prices, are available on the Costing Grants page. Our main supplier is Lenovo, with some additional purchasing from Dell.

Hardware that has reached its end-of-life is disposed of via Converge Technology Solutions. Converge are the preferred Waste Electrical and Electronic Equipment (WEEE) handler for King's, for desktop computing hardware as well as HPC hardware. Any data-bearing equipment is securely erased, and the hardware is reused or recycled.
