ABSTRACT
From the birth of supercomputing, the metric of importance has been performance relative to operations per second, or more specifically, floating-point operations per second (FLOPS). With the cost of power, cooling, and facilities all rising rapidly, a departure from the "performance at any cost" mantra came into the public eye in 2002 with the announcement of the "Green Destiny" cluster supercomputer at Los Alamos National Laboratory (LANL). From the turn of the millennium through the first decade of the millennium, the awareness and necessity of green supercomputing continued to increase and build momentum in the HPC community. What the community needed was a venue in which to compete with respect to energy efficiency, in view of the public eye, with standardized methods and comparable results. Thus was born the Green500. Linpack has been a point of contention as long as it has been used in the Green500.
