PiSort
PiSort is an attempt to bring massive external sorting capabilities to the Raspberry Pi. I created it as part of a planned submission to the SortBenchmark contest, under the JouleSort category. Unfortunately, the submission never came to fruition, as I lacked the equipment to properly measure power usage in the format the contest necessitated. That said, we do have a working software implementation, which I have tested with datasets of up to 1 TB in size on the pi.
