Energy-Efficient Supercomputing Comes of Age with TOP500-Green500 Merge
09 Jun 2016
There was a time when the only thing that the high performance computing industry paid attention to was FLOPS. Indeed, for most of the history of HPC, floating point operations per second was the one true metric, and only those machines that delivered them in the largest quantities were deemed to be true supercomputers. Performance, after all, is HPC’s middle name.

The Green500 List
The purpose of the Green500 is to provide a ranking of the most energy-efficient supercomputers in the world. For decades, the notion of "performance" has been synonymous with "speed" (as measured in FLOPS, short for floating-point operations per second). This particular focus has led to the emergence of supercomputers that consume egregious amounts of electrical power and produce so much heat that extravagant cooling facilities must be constructed to ensure proper operation. In addition, the emphasis on speed as the ultimate metric has caused other metrics such as reliability, availability, and usability to be largely ignored. As a result, there has been an extraordinary increase in the total cost of ownership (TCO) of a supercomputer.
Environmentally Responsible Supercomputing
The Green500 provides rankings of the most energy-efficient supercomputers in the world. We raise awareness about power consumption, promote alternative total cost of ownership performance metrics, and ensure that supercomputers only simulate climate change and not create it.
