IBM HAS resorted to using water-chilled copper plates to keep its new Power 575 supercomputer cool.
The plates are located above each Power 6 microprocessor in the beast to remove heat from the electronics.
The Power 575 boasts 448 processor cores per rack. A single rack features 14 2U nodes, each with 32, 4.7-GHz cores of Power6, 3.5 TB of memory. But IBM still claims it is more energy efficient than traditional air-cooled designs.
In fact, at 600 GFlops per node, the Power 575 is three times more energy-efficient in GFlops per kilowatt than the Power5 generation of air-cooled processors , IBM said.
The system supports very large clusters with hundreds of nodes and enables extreme performance in dense packaging.

Dr. Hermann Lederer, head of Application Support at Garching Computing Center (RZG), Max Planck Institute for Plasma Physics in Garching, Germany reckons the computer "will enable Max Planck researchers to tackle new challenging scientific problems and solve single compute tasks five to 20 times faster than is possible on the current system, which was Germany's fastest supercomputer in 2002."
IBM boffins reckon water can be up to 4,000-times more effective in cooling computer systems than air. µ
