IBM Hydro Cluster Water Cooling  (Source: IBM)
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.

If anything, due to sloppy programming, certain important and common computer usages such as spreadsheets and word processing have slowed down in the last ten years.

Also, I'm still waiting for a computer that can effectively take input other than from a good ol' fashioned (or as Scotty would say, quaint) mouse and keyboard (and please don't tell me speech recognition works - or as the computer would probably hear - cheese bone smell my feet wrecking nation worse).

Is it just me... or is the whole micro$uck/M$/micro$haft thing getting old? I mean seriously? You think you're clever because you can substitute a dollar sign and or derogatory word into the name? I mean it's not like that's been done before. I know this is off topic, but I've been seeing a lot of it lately and its been "grinding my gears". So, I apologize, and at the same time don't.

not to mention vista still doesn't boot any faster than DOS used to on a 286.. :\

seems like all our gains in hardware are almost always (for better or for worse) countered by bloated software..

If you want fast boot times, load DOS 5.0 on your spanky new Core 2 Duo.

Oh wait, you actually LIKE all those new features since then, like a graphical UI, support for multithreading, task switching, more than 640K of RAM, hotswappable hardware like USB keys, etc, etc, etc.

Maybe some of that "bloat" is things you really want hrm? And just maybe (gasp!) its a lot easier to be an armchair-quarterback OS developer, than actually making intelligent comments?

All those things you list are part of XP or older versions Windows. Vista, which I have on two computers, is by comparison to XP, prettier, maybe more Mac-like (pardon my french), has a built in media center (XP MCE? umm..), and is just... better? Oh and as a bonus it takes considerably longer to boot than XP, has half or worse inter- and intra-drive file transfer speeds than XP, is missing the old-fashioned but unfortunately still quite necessary at times fax function (in all but business and ultimate), it cannot remain asleep, waking even out of hibernation on its own (even after manually disabling all device wake capabilities), and has no capability to limit GPU usage while Media Center is maximized (resulting in unnecessary power consumption, heat, and fan noise). But it looks so darn fancy!!! Well, you can't polish a turd.

Na i rater had that MS had just reworked te code of XP and slim it down, rater then blothed it for Vista whit things we dont use anyway ore realy need.

Aero glass looks nice but if they realy had wanted it to work nice, they should had inplemented Desktop vectoring becouse on LCD screens can only be realy used in native res evryting else gets blurry.

And think you have to explain to me how Vista is more inovated then XP and whit me all the other 600 admins i was whit at the MS Technet seminar for the roll out of server 2008.

during the seminar they MS technet guy go's on explaining all the benefits of Win server 2008 working together whit Vista for a bout 30min then he ask how many had rolled out Vista at work ... silent for 10~20sec
Then he ask how many ware planing to roll out Vista ... silents for a other 10~20sec then the hole room start laughing because the technet guy realized that he just wasted a half our on something no one wanted to use.

Because like me the other 600 admins think Vista is just a lemon that no one wants

And private i haven't notice it on my HP Vista machine IE still crashes and that password protection for everything that makes Vista so mouths more safe was bugging me so mouths that i had to turn it of just to be able to normally work whit Vista

After 3 months working whit Vista i was so fed up whit it that i did format C: and installed XP again so that i had control over my own machine again and my drivers ware working again 100% instead basic function driver.

Yeah there are some small things i liked and miss from Vista, but over all they are not worth all hassle that that blotted Vista gives me to use it over XP
