What are the guidlines for the 100TB (1012 recs) JouleSort category?
Many have pointed out that the largest and fastest sorts in the world appear to be egregious wasters. This category is intendend to promote and estimate the energy-efficiency of the largest sorting machines in the world. Since our largest performance-oriented category starts at the 100TB mark, we set the input size accordingly. • The input is 1012 100-byte records generated by gensort. In this case, the records must be binary. • The JouleSort paper states, “Our aim is to account for all energy consumed to power the physical system executing the sort. ” Since measuring the energy consumed by a 100 or 1000 node system can be a challenge in practice, we will accept reasonable estimates based on measurements of pieces of the system. • To estimate energy use across a large distributed system, one must measure the average power of each distinct class of machine or device in the system and extrapolate total average power. The usual rules for measuring the power of individual servers and piece
