NVIDIA: Data Centers Need New Metric For Energy Efficiency
HPCWire, Monday, May 13th, 2024
Data centers need an upgraded dashboard to guide their journey to greater energy efficiency, one that shows progress running real-world applications. The formula for energy efficiency is simple: work done divided by energy used. Applying it to data centers calls for unpacking some details.
Today's most widely used gauge - power usage effectiveness (PUE) - compares the total energy a facility consumes to the amount its computing infrastructure uses. Over the last 17 years, PUE has driven the most efficient operators closer to an ideal where almost no energy is wasted on processes like power conversion and cooling.
