Titan Tops Top500 Supercomputing List
miller60 writes "The new Top500 list of the world's most powerful supercomputers is out, and the new champion is Titan, the new and improved system that previously ruled the Top500 as Jaguar. Oak Ridge Labs' Titan knocked Livermore Labs' Sequoia system out of the top spot, with a Linpack benchmark of more than 17 petaflops. Check out the full list, or an illustrated guide to the top 10."
2013 Calendar full of naked supercomputers displaying their petaflops!
Do it yourself, because no one else will do it yourself. [beta blockade 10-17 Feb]
Obligatory "Crysis Max Settings" joke.
The Internet King? I wonder if he could provide faster nudity.
NASA/Stennis Space Center, Mississippi. Used to be in the top 10. they have fallen way behind.
Sorry to be pedantic, but "petaflops a second" is redundant -- FLOPS means "floating-point operations per second."
more than 17 petaflops a second.
Wait... 17 petaflop per second per second?! How long can it keep that up?
i love how they have a super computer, and are still behind. what an awesome world we live in
Quadrillions of operations per second per second? So these machines only do scalar operations? I thought Linpack was a matrix test =)
There are 4 boxes to use in the defense of liberty: soap, ballot, jury, ammo. Use in that order. Starting now.
does it run Linux?
Petaflops mean nothing! They're just gaming Linpack! This new supercomputer has no capacity for doing REAL science! And oh... errr it's a US machine? Never mind then. USA! USA!
look at it this way: if they hadn't split their acquisition into 2 separate 391 (Rpeak) TFLOPS systems, they'd probably be good enough for #36.
Between all the time it takes to upgrade these beasts, and the time spent running proper benchmarks, how much time is available to run actual jobs?
"with a Linpack benchmark of more than 17 petaflops a second"
Supercomputers calculate on an accelerating performance curve now?
When will these press releases start giving some information about the OS and the way of scheduling and patitioning the tasks?

to get into Titan with a magnetron....
would have made it onto the June 2000 supercomputer list, and would have made 2nd place in the June 1993 list, both with the CPU alone. At least if Dongarra wrote the Linpack code :-)
2.3 GHz, 4 cores, 256 bit vector registers, one add + one multiply per cycle throughput = 73.6 GFlop/s theoretical limit; with hyperthreading one should get quite close to that limit. Top 500 in June 2000 was only 44 GFlop/s, 2nd place in June 1993 was 30 GFlop/s.
Meh. I have an $80 video card that does around 700 GFlop/s, and they sell cards that do 5600 GFlop/s for $1000 MSRP (GTX 690). The supercomputer in question does 17,000,000 GFlop/s. That's equivalent to 3,000 GTX 690's, or about 24,000 of my video card, or about 230,000 of your laptop.
p.s. If "Moore's Law" holds up, they might be selling ~$1000 video cards as fast as the supercomputer in 2029, or $80 video cards that fast in 2033, or laptops that fast in 2038.
Are we in a race to see just how fast we develop AI that will kick our asses? Skynet or the Forbin Project seem to be the goal.
The mind conceives, the body achieves, the spirit manifests.
Not only it is based on AMD Opterons, but on Opteron 6274, the Bulldozer architecture, which is bashed by every (desktop) review and here on Slashdot. It is funny that a "completely useless" processor powers the fastest computer in the world.
To be fair, only Phoronix does real server benchmarks, and even they have a different objective, not processor benchmarking. And to a large extent every benchmark is useless, you always have to benchmark your own application to get results which can be taken seriously.
Bear in mind, part of it has to do with *how* cores are counted. I wasn't at the top500 announcement this year (didnt have the time to head to SLC for a week, wish I did), so I can't speak to if they discussed it, but at previous SC top500 announcements in the past few years they've stressed the difficulty in reconciling core counts between GPUs and CPUs, including (last I heard) settling on a 4:1 GPU vector procs:cpu equivalent ratio for NVIDIA cards.

I think we are reaching the point where we are not limited by hardware as much as software. It seems like all these ultra-fast supercomputers can do is fairly simple calculations but at a massive scale. I bet we could do a lot more with the hardware we have now if we developed more subtle and complex software similar to how brains function.
The obvious question "which are running Linux" is almost impossible to answer. Are they sponsored by Microsoft? However, you can use the "sublist" feature to make a list of the first 500 computers and limit to "Linux" as operating system. The list contains 469 entries, and the first number that is missing from this list is "38".
Huh.
So while it will refuse to actually show the OS, the sublisting feature makes it able to wrestle it out indirectly.
Will Colussus and Guardian be measured separately or as a single device?
