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.

By 2018 I think we will have operating systems that will want to take advantage of the available hardware even for average use, and succesfully implement, or at least try to, things like the following:

- natural speech recognition
- virtual, more intuitive and immersive GUIs making extensive use of 3d graphics
- more embedded AI to take on simple maintenance tasks and repetitive actions responding to usage patterns that by today require active user intervention

Your average Joe will want a speech commanded computer evne more so than your average computer geek.
Fancier, more intelligent and intuitive interfaces on OSs are not there to benefit the power users as to make the less savvy ones get more easily comfortable with machines, so your average user will want the latest and greatest OS supporting the best eye candy experience he can get because it'll probably reduce his need to interact with the computer to a bunch of simple commands (issued by voice or simply by making gestures by waving your hands in the air rather than using a keyboard).

I think browsing the net 10 years from now will not mean just using a 2d browser showing 2d content, but something much richer and immersive.

2d browsing can't get much better than what we have now. I think tabbed browsing is the first shy step to start thinking about a 3d browser, and from them on 3d content should start appearing to take full advantage of the fact that even the cheapest IGP will have ability to decently cope with real time 3d content.
