Blue Gene/L Beats Own Speed Record
Linked by Thom Holwerda on Sun 30th Oct 2005 15:30 UTC
IBM Now that full complement of 12544 Power5 processors have been installed, the Blue Gene/L supercomputer has hit 260 teraflops. Lawrence Livermore National Laboratory and IBM unveiled the Blue Gene/L supercomputer on Thursday and announced that it has broken its own record again for the world's fastest supercomputer.

Great work. I just dont quite understand "12 544 Power5 processors". So how many processors is that? 544 * 12 = 6528 processors?

12 544 = 12,544 or 12.544, depends on where you're from. Outside of the English-speaking world, people use . instead of , for thousands. In order to prevent misunderstandings, I or omit the ,/., or I just add in a space.

I think this 12544 with nothing needs to be the world wide standard with. 12 dot 544 for fractions <-;

I will write a letter to my MP

This website is in English, so it only makes sense to use the conventions of English-speakers.

The consideration is appreciated, but I'd really be hard-pressed to believe that anybody would think that there are twelve and one-half processors in a 260 teraflops machine!

Well, the Japanese will be angry... I seem to recall them attempting to build (with government support) THE fastest supercomputer in the world so Japan can regain the prestige of once again having the fastest supercomputer.

Yeah, I wonder what happens when BlueGene/P is finished ;)

Blue Gene/L is the "custom" system, made up of 65,536 custom CPU Nodes, each containing an ASIC with 2 PPC 440 (Book E) core, and subsystem support (cache, etc). It's noted here:
http://en.wikipedia.org/wiki/Blue_Gene
It's the ASC Purple that's composed of the 12,544 POWER5 Dual core processors. It's a more conventional supercomputer setup. This is the 100 Teraflops machine.
The Blue Gene/L is what one might call an "exotic" architecture, using lots of smaller processor nodes for doing work. Hmm, can you say "CELL".

ZDNET tomfoolery

thanks anonymous.
I was getting really pissed at the usual ZDNET tomfoolery.
how the hell does one get the facts of ones own article wrong in the header?
The Article clearly states that ASC(I) Purple uses 12544 POWER5 processors, and that BlueGene/L uses 65*** custom Power Variant processors. (If I remember correctly from years and years ago, variants that emphasize vectorization.)
It's all there, yet ZDnet (cnet) mainstream sucky news manages to mess up their OWN headline.
how is that even possible?

It doesn't run Halo.
The OS is Linux.
