Blue Gene Lite is cooler (Score 1)

The Blue Gene Lite system by IBM is actually running even cooler (article).

The 440PPC processor being used is designed for embedded computing, so each node (2 processors and 4 FPUs) uses only 15 watts per node. That means that the 1024 processor system (512 nodes in normal configuration), now at #73 in top500, only uses about 7.7kW of power. At 240 processors or 120 nodes, power consumption would only be 1.8kW. This is far better than the Transmeta numbers.
