COLSA, a U.S. Army contractor based in Huntsville, Alabama, today announced the purchase of 1,566 Xserve G5s to build a new supercomputer expected to be one of the fastest in the world. The supercomputer, named "MACH 5," is expected to deliver a peak performance capability of more than 25 TFlops/second at a cost of US$5.8 million and will be used to model the complex aero-thermodynamics of hypersonic flight for the US Army.

How cool is that! 25TFlops should stick it in the top three with ease as far as i can remember, although IBM are currently working on a supercomputer thats probably going to knock the earth simulator off the top spot in a couple of years!

IBM... hmm... does that mean it?s going to be with G5s? a supercomputer by IBM themselves?

The latest edition of the Top 500 list of the world's fastest supercomputers reveals that Japan's Earth Simulator supercomputer, built by NEC, retains the No. 1 spot for the third year in a row, while a new system called "Thunder" claims the No. 2 position. It is an Intel Itanium2-based cluster system at Lawrence Livermore National Laboratory (LLNL) in California. In addition, No. 4 and No. 8, prototypes for the upcoming IBM BlueGene/L system, make the list for the first time. The prototypes are a joint development of  and IBM and are currently at IBM's facility. The final system will be installed at LLNL and is expected to replace the Earth Simulator by June 2005 or by the end of 2004.

Dosn't sound like G5's... But rather somthing custom betweeen LLNL and IBM. - seems daft though considering the power to cost ratio of the G5 Xserves - Hell look at the difference of the cost of this new Xserve one at 5.8Mill conpared to the 350Mill Earth Simulator - yet the power difference is so small!

     Yeah, but if it is something custom, that's R&D that IBM is being paid for. That's good for the industry.

True, very true, and you never know it might just trickle its way down into the G6 Wink

Amazing to think how cheap you can get a seriouse supercomputer now though compared with say, 5 years ago

That sums it up a lot better. I think we now know where the G5 Xserve supply has been disappearing to.

Hypothetically -

How fast could a supercomputer made up of X-Serve G5's be if they spent the same amount of money as the really expensive clusters? (?350 mil)

meh we should be able to work that out. If we divide the cost of the Virgina tech computer by the number of nodes, then multiply by the closest denominator to reach 350million, then take that number and.... oh shit im lost. but its definatly easy to do... isn't it?!

I ran the numbers on the Virginia Tech supercomputer, way back a whole long time ago.

Baring everything that i dont know about (which is everything) it was some absurdly more powerful computer, for the same 350 million cost.  It really isnt that hard, i mean, how many Tflops can the VT computer pull now?  Divide 350 million by the cost of the Virginia Tech supercomputer, then multiply that number by the number of TFlops the VT computer can do right now.  And you have your answer.

350/5.5(?) = 63.5 (?) 63.5 x VT SuperComputer Terraflops = ?

His math is irrelevant because these clusters will not scale linearly.

Baring everything that i dont know about (which is everything)

Ace, i was running the numbers ignoring the fact that they wouldnt "scale linearly" as you say. I knew something like that would probably make my calculations moot.  But Ace, what would happen, would the end computer for 350 million be more powerful than what the numbers were that i came up with? Or would it be slower?

And by your guestimation, how much in each way?

Cmon mr. smart guy, enlighten us laymen.  Wink
