back to article Oak Ridge lab: Behold, I Am TITAN, hear my 20 petaflop ROAR

Oak Ridge National Laboratories is really eager to talk about the "Titan" supercomputer, which weighs in at more than 20 petaflops of performance and which has just been activated this month. In fact it's too eager to wait until the SC12 supercomputing trade show in November to give out all the feeds and speeds. Cray and Nvidia …

299,008 Opteron cores

Holy crap.

And this is why AMD still isn't out of business.

How does 300k cores compare to an average data centre?

Re: 299,008 Opteron cores

Fujitsu/RIKEN's K computer has 700,000 SPARC cores. The comparison (setting aside the GPU part of Titan) is quite interesting:

K: ~700,000 cores, ~10 petaflops

Titan: ~300,000 cores, ~3 peteflops.

So K's SPARC cores are doing rather better than Titan's Opteron cores. Which suggests that a hypothetical SPARC/GPU hybrid would be quite an impressive machine!

It's also interesting to note that the GPU element of a Titan node delivers about 8 times the performance of a K SPARC node and about 9 times the performance of the Opeteron part of a Titan node. Somehow factors of 8, 9ish feel a little disappointing; GPUs are massively parallel internally (hundreds of cores) but it's not adding up to hundreds or even tens times quicker than a CPU. Still, the Titan is a truly impressive bit of kit.

But can it play Crysis?

And does it support Flash?

No and No - No flash, no Crysis, but it did print out an interesting recipe for creamy rice pudding that I want to try out....

WTF?

"...the US Department of Energy hopes will facilitate significant breakthroughs in research in the physics, combustion, materials science, nuclear energy, and combustion."

Are they planning to set fire to it?

I'm more impressed that it takes this much computing power to simulate an internal combustion engine.

Forget nuclear modelling

Combustion is so important, they have to mention it twice

Obviously a Blazing Saddle fan...

"Qualifications?"

"Physics, combustion, materials science, nuclear energy, and combustion."

"You mentioned combustion twice."

"I like combustion."

"upgraded to 298,592 x86 cores..."

Yeah, but nothing really uses more than one core anyway.
