US Air Force Buying Another 2,200 PS3s
bleedingpegasus sends word that the US Air Force will be grabbing up 2,200 new PlayStation 3 consoles for research into supercomputing. They already have a cluster made from 336 of the old-style (non-Slim) consoles, which they've used for a variety of purposes, including "processing multiple radar images into higher resolution composite images (known as synthetic aperture radar image formation), high-def video processing, and 'neuromorphic computing.'" According to the Justification Review Document (DOC), "Once the hardware configuration is implemented, software code will be developed in-house for cluster implementation utilizing a Linux-based operating software."
Maybe someone should tell them the new ones don't run Linux.
Since Sony's strategy (like Microsoft's) is to sell the consoles below production costs and make money on the games I guess that they are now pretty angry about organizations buying PS3s solely for computing...
Are we still at the point where we can't get hold of Cell processors for machines specifically designed for this sort of task?
I haven't checked the details yet, but I was told that IBM QS21 is Cell based blade system
-- Reality checks don't bounce.
They would buy Cell processors, but then then it would take an year and a half for the papers to be processed, six month for IBM and Dep.Def. to spec the systems, and about two years while competitors contest the order ... everything costing about 10 times as much for one half of the computing power, and would not be able to run much else besides floating point calculations.
BTW, has anybody tried DwarfFortress on a PS3 ?
They should wait for Black Friday, nobody is going to fight the Air Force for a doorbuster...
I suppose if they ordered a system designed specifically for their purpose it would cost a dozen millions more on top of this half that you mentioned and then they still had to do in house software stated in the summary. So indeed they saved some - even if you consider all the military expense a nonsense anyway it was still half a mil wasted instead of a dozen.
This is the US Government we're talking about. One of the few entities on the planet where "Budget" is virtually meaningless. Someone sneezes funny and a million dollars goes out the door. How much do you think it'd cost to financially compel Sony to enabling Linux installs on their machines? Exactly how much does a PS3 dev-kit license cost again? How hard to do you think it'd be to get a judge to sign some order compelling Sony to releasing the schematics to the US Government under NDA, so that they can write and maintain their own Linux loader for the machine?
Even if the cost of the above was in the lower 8-digit range without the machines included, which I really doubt, it'd likely be cheaper to source these machines than it would be to develop your own hybrid compute node and software for it (or nVidia's crazy-expensive, less mature solution).
Sony doesn't support Linux on these machines, which makes it practically impossible for the home user to boot Linux on them. (Well, tbh, 'improbable', look at how much reverse engineering has happened with the GameCube & Wii). But for someone with deep enough pockets, like say a government agency, it's almost trivial.
