Executive Summary

In this paper, the authors describe the submission for the 2010 10GB JouleSort competition. The system consists of a machine with a low-power server processor and five flash drives, sorting the 10GB dataset in 21.2 seconds (?0.227s) seconds with an average power of 104.9W (?0.8W). This system sorts the 10GB dataset using only 2228 Joules (?12 J), providing 44884 (?248) sorted records per Joule. The entry for the 10GB competition tried to use the most energy-efficient platform they could find that could hold the dataset in memory to enable a one-pass sort.
