IBM Power 575 performs at 600 GFlops per node

Computer enthusiasts that overclock their CPUs have known for a long time that liquid cooling has the potential to cool the processor better than air cooling. Liquid cooling in the enthusiast space is common and has even given way in the extreme performance categories to much more exotic means of cooling processors.

In the supercomputer realm companies like IBM have traditionally relied on air cooling for the CPUs via air conditioning for the room the supercomputer is in. IBM introduced its latest supercomputer called the Power 575, which is equipped with IBM’s latest Power6 microprocessor. The Power 575 has moved from air cooling to liquid cooling and thanks to the liquid cooling useing water-chilled copper plates located above each processor, the new supercomputer requires 80% fewer air conditioning units.

The significantly reduced need for air conditioning means that the energy needed to cool the data center can be reduced by 40%. IBM researchers say water can be up to 4,000 times more efficient than air cooling for computer systems.

The Power 575 supercomputer has 448 cores per rack and provides over five times the performance of its predecessor and is three times more energy efficient per rack. Each rack features 14 2U nodes each consisting of 32 4.7GHz cores of Power6 and 3.5TB of memory. Each node is capable of 600 GFlops and is three times more efficient in GFlops per kilowatt than the Power5 air-cooled processors.

10 Years Ago:

Buildings, bridges were the same.
Planes and ships were essentially the same.
Computers were completely different.

I know nothing of buildings, bridges, or ships. However, I work on avionic equipment and let me tell you... 10 years makes a big change in aircraft communications and flight control systems (not to mention munitions systems, radar systems, and electronic warfare systems for military jets). The air frames may look similar, and in the end they do about the same job... but they are more efficient and reliable. The point is that technology advances on all fronts, it just not may seem as obvious to the masses in many sectors because most do not deal with it on a daily basis. Pretty much everyone uses a computer so they can see the changes. Just look at the F-117 Nighthawk. The last plane wasn't even delivered until 1990 and already it is being retired... in roughly 20 years it went from top-secret project to obsolete.

it just not may seem

it just may not seem*.... alright. DT REALLY needs to figure out some way to let people make minor changes to their posts. Either that or I'll just continue smacking myself on the forehead and replying with the correction...
