Abstract: Since 1991, the performance per watt of a supercomputer has only improved 300-fold and the performance per square foot only 65-fold. Clearly, we are building less and less efficient supercomputers, thus resulting in the construction of massive machine rooms, and even, entirely new buildings. Furthermore, as these supercomputers continue to follow "Moore's Law for Power Consumption," the reliability of these systems continues to plummet, as per Arrenhius' equation when applied to microelectronics. To address these problems, we constructed Green Destiny, a 240-processor supercomputer that fits in a telephone booth and sips only 3 kilowatts of power. Green Destiny provides reliable supercomputing cycles while sitting in an 80-90 F dusty warehouse at 7,400 feet above sea level, and it does so without any special facilities, i.e., no air conditioning, no humidification control, no air filtration, and no ventilation.
