Los Alamos National Labs has begun taking bids to build the world's fastest supercomputer

Los Alamos National Laboratory (LANL) announced yesterday that it has begun taking bids to upgrade its existing computing power and to begin work on building the world’s fastest supercomputer.

The new supercomputer would be tasked with ensuring that the United States nuclear deterrent program remains operational without the need to detonate live nukes underground to ensure they still work. “LANL currently has some of the most limited computational capabilities of all the DOE laboratories. That will change with this new petaflop computer, which will fill an immediate need to increase the lab’s computing capabilities,” New Mexico Senator Pete Domenici said.

The new supercomputer, dubbed "Roadrunner," will operate at 1 petaflop initially with the ability to scale to 2 petaflops as the project is completed and will cost an estimated $900M USD when all is said and done.

and who pays for all of this? Thats what I'd liek to know :P

The government internally calls them "suckers." We like to call ourselves tax payers. ;)

90M is pocket-change compared to the first DOE super-computers!

hrrm your bitching about 90mil when the us govt spends how many billions on other defence projects

let me get this right... $90 for 1 petaflop for physics (bomb explosion simulation) based algorithmns.

Thats a lot of power.

But 1 petaflop = 1000 teraflop

and a single pentium 4 3.0GHz is approx = 3 to 4 teraflops.

Therefore a nest of 300, 100% efficient pentium 4 3.0Ghz would meet this calculation target. In practise, there is a lot of inefficiency in scheduling and this probably wouldn't match the 1 petaflop target. But the cost would be, say, 300 x $2000 = $600,000. Much less than $1M and nowhere near $90M.

BUT wait a minute , isn't the recently announced AGEIA PhysX supposed to be 100x as powerful as a pentium 4 3.0GHz at physics calculations? ie. One PhysX has been marketed to be (although on different calculation terms) circa 200-400 teraflops.

That means I could build one Pentium 4 workstation board, with each PCI slot (ie 5 of them) filled with an AGEIA PhysX, and a nice GPU so demonstrate the "boom" in real time graphics.

Now that would cost me, (and being very generous with my budget), $2000 for workstation board CPUs RAID and HDD subsytem, $500 for GPU and 5 x $300 for PPU. All in $4000.

The net rip-off to the US taxpayer = $90,000,000 - $4000 = $89,996,000.

Someone please tell me where I got my math wrong. Thanks!

Oh man, I wish I had an edit button. I just found out the "wiki" I was on was a horrible European site where they use a "," for a decimal point. Therefore my power calculations are wrong by a factor of 1000. :?( how embarrasing

Ok multiply my buget by 1000x and you get $4M for the consumer solution. A military one-off would be at least 10x a build your own price, so $40M. Therefore $90M allows a little room for the contractors profit margin :-)))

Excuse me, that sort of miliatary hardware is supposed to be fail proof. Read: More money to make sure it doesn't fail easily.

Besides, PhysX processors are not GP processors, they may not be able to handle all that is necessary.

Since when can a P4 do 3 to 4 teraflops? More like gigaflops. 4 Teraflops gets you onto the supercomputer top100 list.

So to reach a petaflop, you need 300,000 p4 workstations. I'm going to wager that 300,000 individual p4 workstations will consume a lot more power than a purpose built supercomputer.

Also don't forget that the initial cost of computer systems is usually a fraction of the system's lifetime cost - the rest is spent on maintainence and training/paying people to run it. If it breaks, who will fix it? You?

Also, now that you have 300,000 p4 workstations sitting around, how will you turn them into a supercomputer? To take advantage of those processors at 100%, you're going to need to saturate their bandwidth in the range of several gigabits per second EACH. How would you accomplish this? A standard network? I'm sure the fibre optic interconnects in supercomputers add something to the cost.

You'd also need an operating system that can manage them. Open source linux can scale as well as cray's operating system when dozens of processors are involved, but how about hundreds of thousands?

Finally, AGEIA PhysX might be able to do 100x as many physics calculations per second as a CPU, but those are dedicated physics processors, not general purpose processors. They also may not have the floating point precision they seek.

There's usually a good reason why people do these things. I personally would assume that the people at Los Alamos know more than I do.

For your digestion, check out
#3 can hit 60 teraflops with 10,000 processors. With 300,000, at the same scaling, they should hit 1.8 petaflops.

Pfft, I have a 5 exaFLOPS machine in my basement.

I overclocked MY 2 PetaFlop supercomputer to 2.7 ON AIR! Thanks, Zalman!

Best part: I can play Oblivion with all the settings turned on high. Well, for 10 minutes, anyway. Wish I weren't stuck with AGP...

Networking ain't cheap...

I know you were kinda joking but...

If anyone thinks that these tens (hundreds?) of thousands of nodes in the cluster are networked using the gigEth port on the mobo, you nuts. Anybody know the cost per port for Infiniband or Myrinet? And these are the cheaper cluster solutions. Imagine the cost of a proprietary solution.

Myrinet cards go for about $500. The switches cost a fair whack to. And you dont want to know about the cables.
A 1U server with 2 opterons will set you back about $3000-$4000 (without the myrinet card)

Would be nice to see the RFP then we would know what they was looking to getting CPU wise.

what companies make the chips and boards for this kind of computer? my guess is intel but that's completely uneducated...

IBM and CRAY are the major leaders. CRAY builds their own hardware I believe. Obviously, they outsource the manufacturing but I'm pretty sure most of these computers are designed in house. You guys ever read the story about a guy in a NYC apartement building a supercomputer (that took up the whole apartment) that matched the power of the CRAY's at the time in order to calculate PI?

Buyers guide

Would anybody care to suggest a buyers guide for $ 90M?

It's outdated I say!

It's already discontinued. Besides, the Japs will come back out on top. Gary Kasparov will still win at least one match against it's 'I can calculate faster than the bigbang, therefore I am unbeatable' algorithm.

The software cost a lot

Having 3000 or so PC linked together will not make it one super computer, it is still 3000 PC. Like others said, the connection and scheduling (or other software) that makes the whole thing works is going to be the key in performance and scalability.

Without scalability, you may add 1000 CPU and not make the system any faster.
