Fastest SuperPi?

[Nazca]

How fast could the IBM Blue Gene/L (world's fastest supercomputer, with 32,768 processors) do SuperPI to 1M, or even 32M digits?

I'd reckon it would thrash Coolaler's attempt a little

 

[KizZ]

Hmmm.

 

[Jokester]

Actually, I wouldn't be so sure. SuperPi is single threaded so it wouldn't get any benefit from the multicores. Typically the individual processors aren't that powerful, certainly not as powerful as a Conroe core I would have thought.

The one at the place where SuperPi comes from can find 1m in 5 seconds, probably faster now as time's moved on.

 

[Gashman]

could you not run super-pi on the PS3, i reckon all those cells should come up with respectable time?

 

[Gibbs]

has the cell not got 8 cores?

EDIT:

the Cell processor can be split into four components: external input and ouput structures, the main processor called the Power Processing Element (PPE) (a two-way SMT multithreaded Power 970 architecture compliant core), eight fully-functional co-processors called the Synergystic Processing Elements or SPEs and a specialised high-bandwidth circular data bus connecting the PPE, input/output elements and the SPEs, called the Element Interconnect Bus or EIB.

i think it has 7 cells and 1 control (poor word i know) one, but apparently floating point performance is 218GFLOPs, which is a fair few flops whatever a flop is...it is in theory mind bogglingly powerful though, and each cell runs at 3.2Ghz i believe

Edit: so in theory its a eight cored processor...which is nice

Yeah unfortunately the yields are horrific so its also turning out to be mind bogglingly expensive for Sony

but, the question is, could it beat the conroe time in super-pi if it would work? the RSX is apparently 99% identical to G71 (which is 7900 i believe) but will be a lot faster as all games made for PS3 will be optamised entirely for that GPU, wish they could do that with PCs, maybe with unified-shaders this might become possible

I don't think unified shaders is going to make it much easier to optimise for PCs, there will always be a huge range of hardware a PC game must run on, different amounts of memory, CPU speed etc. The benefit of a console is that you can optimise levels to fit in the memory, you can dynamically allocate the memory pool as and when its needed etc.

hench why the PS3 is potentially so much more powerful than a 3.2Ghz PC with a 7900GTX, pity no benches can be run, i would like to see how much power it actually has to be honest

I heard all this with the 360 went out and got one and the gfx are ok but nothing to write home about atm.

 

[slap ed]

so what is the fastest 1mb super pi score ?

Yeah its all great in theory. At tv resolutions even HD it looks so naff when you are used to a 1920x1200 display.
