IBM has introduced a supercomputer equipped with a water
cooling system that reduces energy consumption by 40 percent.
The Power 575 supercomputer uses water-chilled copper
plates above new IBM Power6 microprocessors to remove heat.
The setup requires 80 percent fewer air conditioning units
and, due to the water-cooling system and latest processors,
is three times more energy efficient per rack than supercomputers
that use previous microprocessors.
The Power 575 is designed to handle intensive computing
problems related to energy, engineering, aerospace and weather
modelling. The National Center for Atmospheric Research
in Boulder, Colo., plans to upgrade to the Power6 version
of the supercomputer.
"Ever faster computers are vital to our research on hurricane
formation and climate change" - Al Kellie of the Center
said in a statement. "We're especially pleased to see that,
with the new Power 575, IBM has been able to drastically
increase performance while remaining very energy efficient."
