Top 500 Supercomputers Ranked
Shadow Wrought writes "The Register is reporting on (alternate ZDNet article) the latest list of the top 500 supercomputers in the world. Top of the list is the Earth Simulator Center in Yokohama, Japan, with a benchmark performance of 35.86 Tflop/s. HP and IBM claim 159 and 158 of the systems respectively. I wonder how many teraflops Deep Thought could have done?"

Since it was a chess computer, I'd say it could probably do about 0.000 FLOPS.

The Top500 server was slowed to a grinding halt of php time-outs by a number of measly desktops.

The NEC Earth Simulator is really just a different optimization point in the computer-design space. Huge amounts of bandwidth to memory and specialized vector-processing units tied to the processor core. The VLSI technology that NEC used to build these system is readily employed by Intel and IBM. So, if the latter companies wanted to build the world's fastest HPC computer, they could.

I don't see any major changes in this list compared to the one that has been up for almost 6 months. Only a couple of the computers on top25 has been been build this year. I'm certainly looking forward to see some new top placements in the near future (anyone know of something which might appear soon?). btw. the server isn't too fast, even when it's not slashdotted.

Interesting to note is that #3, #6, and #8 are all linux clusters. All three of which are at Livermore.
Cray's X1 also debuted, but it was much lower @112. However, it ought to be noted, that the examples out so far are only 60 processors at tops. As soon as the money gets ponied up, prolly at ORNL, they'll be waaaay up towards the top. My guess is, if all goes as planned, they'll be at #15 by year's end.
What I find exciting these days is actually the High Productivity Computing Systems Effort, the Blue Planet or Blue Gene. These are a little ways off from being on the Top500 list yet though. :D
I do wish there were more SC companies doing hardware development in the US. I love Cray, but a single vendor smacks of eggs in one backet syndrome...So, geeks, if ya wanna start a startup with a design, go for it...Betcha the NSA (aka Cthuhlu of HPC) would be happy to sponsor ya...;)
Do you know why the road less traveled by is littered with the bones of the unwary?
yeah, but people are gonna mod him up as interesting... typical.
Is this what slashdot evolved into ? A top-500 list of supercomputers decided upon using dubious benchmarks that are not representative of computing power ?
Doesn't any of us remember that FLOPs, as MIPS, are Meaningless Indication of Processor Speed ?
I'm feeling a little deceived actually...
Karma cannot be described by words alone.
How long is it before consulants and engineers run their simulations (like road traffic and passengers at airports) on small sized supercomputers? So, far it seems like single desktop is still the norm.
New year Resolution: Don't change sig this year
What I want to see is the list amended to include the iron that agencies like the FBI, CIA, NSA, and less well known acronyms are using.
My question to anyone out there that might now is what location has the highest computing resources. Looking at the list, it seems like Lawrence Livermore has at least 3 systems in the top 50, and more from there on down.
Anyone have a toal available resources in one location list?

The evil monkey commands you to dance.
That's what slashdot itself is running on, how else could it survive what can only be described as a 24/7 superslashdotting ;-)
Now how many of those run linux? SCO might be reading this too.
So.. does this mean that this is done in real-time???
This list would probably have been dominated by elxsi, Connection Machines, and Crays, if things had been different.
I never saw a live CM or Cray, but I did play on an elxsi, and it was a pretty hot system for it's time.

In my experience, a lot of small businesses rent time on university supercomputers to do some heavy simulation. But i also know of several small companies that run their own clusters. With x86-based hardware at a relativly low cost, i think that is evolving to be much more common in the near future.

Sheesh, I wonder why my rig didn't make it into the top 500 either?
I've spend a lot on a window, neon lights, fancy cooling systems, and STICKERS.. so many that I should rank atleast 354 out of 500!! It even sounds fast from all the chassis fans!
Maybe I need to go for the rear mounted spoiler to break onto the list??
Yep, love them Mac-fags, huh? Say something blatantly ridiculously optimistic about the performance of a Mac, they'll mod it straight up. Easiest Karma-whoring on slashdot.

Seeing how its been slashdotted, how high does the PS2 cluster, if it is even in there, rank? If it is really high, I suppose we can imagine daisy chaining a bunch of modded xboxs.
Could some organization or individual (gates gov whomever) with a ton of money had a supercomputer of this size built but not allowed it to be listed or not told anyone that they built it or classified it as top top secret. I don't know what they would want it for but I there could be a couple out there.....
I'd find it fascinating to see a breakdown of the languages used to write the applications which are running on these beasties. High Performance Computing has rather different needs from a language than programs that are, say, focused on interaction with a user, or database access. I expect that languages which sit well with infrastructures such as MPI and Open MP would be well-favoured, and I wouldn't be surprised to find that FORTRAN puts in a respectable showing.
And before I'm bombarded with comments pointing out how ancient FORTRAN is, it's worth remembering that FORTRAN is still an evolving language; the last updade came out in 1997/98, and the new FORTRAN 200x should be arriving within the next year or so. In my experience of a number of languages, I've found that FORTRAN still continues to excel at numerical efficiency and portability, and I hope these selling points continue to be a feature of the new standard. Of course, I wouldn't want to write a compiler in FORTRAN, but for stuff like computational fluid dynamics, it still rocks; and those aspects of FORTRAN 77 which made it awkward (such as lack of dynamic array allocation) are fortunately a thing of the distant past.

I wonder where on the list my companies cluster will show up. IBM is building a 500 node, dual 2GHz PIV Xeon cluster for doing various tasks including DNA research.
You're lucky you're far enough away from the black hole that is Rolla, Missouri.
it's still not playable in software mode (especially for CS/halflife)
My experience with running applications on these machines (massively parallel) was with the mathematical modelling of dynamic large-deformation phenomena (i.e. car crash simulations) every application I used was written in FORTRAN, and still is. FORTRAN is alive and very well.
I bet the Earth Simulator can't simulate Slashdot earthlings hitting a web site.

What if there were a beowulf cluster of the top 500 supercomputers?
:) Well, I guess it might be if there were an infinite number of computers, but unfortuneately this recursion has a root :( Actually, I think the answer to your question would be "a beowulf cluster of all computers in the world".
I suppose, if you truly see a beowulf cluster as a single computer, it would then be the fastest computer and the next 499 fastest would have to be aought out. But then the cluster would have to include these next 499 since it's a beowulf cluster of the 500 fastest. But then... is this a paradox?
"Question with boldness even the existence of a god." - Thomas Jefferson
Oh, come on. Everyone knows that God uses a Mac!
Pink is the largest LinuxBIOS cluster in the world to date. The only moving parts in each node are cooling fans. This translates into a small savings on hardware, but more importantly means the nodes are by design more reliable thanks to fewer moving parts. Each node is powered by two 2.4GHz Xeon processors with four gigs of RAM and Myrinet 2000 interconnects.
The raw hardware power, while impressive, isn't what makes this cluster unique. The kicker is in the software, more specifically Clustermatic 3 featuring LinuxBIOS. Stuff happens and nodes fail, but thanks to LinuxBIOS they can be back up in a matter of seconds, not minutes.
Additional tools for the frontend node from Linux Networx makes updating nodes super-easy. You can flash each node's BIOS with a single command all in a matter of seconds. BProc allows you to run basic shell commands on any node without even installing a distribution on those nodes. w00t!
What we see here is a big shift away from expensive hardware and proprietary software. The software powering this cluster is 100% GPL, so users save a fortune in software licensing costs alone. And while these P4 nodes in particular aren't exactly cheap, they provide pretty darn good power and are far less expensive than Alpha servers. Also, using the x86 architecture means that consumer boards are not far behind in clustering. In fact, you can check out the LinuxBIOS homepage and see some pretty cheap boards that are supported already. So if you have some spare cash lying around and a couple weekends to kill, you can pick up a cheap board + cpu + memory combo and set it up as a slave node for your desktop machine with the same software these guys use to power this huge cluster.
Is NCSA (National Center for Supercomputing Applications) still around? I thought they would have made this list, or did they go out of business?

Sandia May Help U.S. Regain Supercomputer Lead
By John Fleck
Journal Staff Writer
Sandia National Laboratories is negotiating a deal with legendary computer-maker Cray Inc. to build a $90 million supercomputer for nuclear weapons research.
In years past, this would likely be headlined something like "Sandia tobuild world's fastest computer." But the days of Sandia and the other U.S. nuclear weapons laboratories leading the world in high performance computing are gone.
The new Cray machine will be tremendously fast, and so big that a $3 million building must be constructed to hold it. But U.S. supercomputers have fallen far behind Japan's best.
Experts say the Sandia-Cray deal is an important step, however, in pushing the United States back toward preeminence in the supercomputer world.
The Sandia-Cray deal has the potential to push the state of the art in computer technology, said Horst Simon, director of the National Energy Research Scientific Computing Center in Berkeley, Calif.
Sandia announced in June that Seattle-based Cray has been chosen to build the labs' new computer.
Officials will not talk in detail about the deal until negotiations are complete, expected later this month. But in written responses to questions from the Journal, Sandia supercomputer program chief Bob Thomas said the new machine will be at least seven times faster than Sandia's current fastest computer.
That would make it second fastest among supercomputers currently operating around the world, but still well behind the Earth Simulator, a research machine built by Japanese computer giant NEC for a Yokohama-based research consortium.
The Earth Simulator shook up the high-performance computing world this spring with a staggering top speed of 36 trillion calculations per second, five times faster than its nearest competitor.
It was the first time in five years that a U.S. nuclear weapons laboratory has not held bragging rights as "world's fastest." For most of those five years, the title belonged to Sandia.
"The Japanese now have a trophy on their mantle," said University of Tennessee supercomputer expert Jack Dongarra.
But more than a trophy, leadership in high-performance computing is important to national security, Dongarra and Simon both argued.
Sandia and the other two U.S. nuclear weapons laboratories have long pushed the state of the art in high-performance computers in order to run the simulations needed to understand nuclear weapon design, reliability and safety.
Despite the Japanese leap to the title of "world's fastest," four of the 10 fastest computers in the world are at U.S. nuclear weapons labs, including one at Los Alamos and one at Sandia.
Among other things, the new Cray machine will be used to simulate warhead performance in the high radiation of a nuclear battlefield, according to Thomas.
While details about the new computer will not be revealed until the Sandia-Cray negotiations are complete, Simon said it is clear that Sandia is pursuing a different strategy to build the new computer.
The other large machines being bought by U.S. weapons laboratories are built around clusters of the sort of fast computers used in the business world.
"The machines we've been buying are nothing more than souped-up webservers," Simon said.
In contrast, in buying from Cray, Sandia has turned to a manufacturer that builds far more specialized machines.
After a series of mergers and corporate deals, the Cray of today is very different from the company that in the 1970s built the world's first "supercomputers" at Los Alamos.
But despite the corporate differences, the move to buy from Cray suggests that Sandia wants a machine designed specifically for scientific applications, Simon said.
Do you know why the road less traveled by is littered with the bones of the unwary?
does it support Ogg?
The article should read "Top 500 Supercomputes that we know about Ranked".
Wouldn't you love to know what the NSA uses to crack 128-bit keys? Ever wonder if the solution to RSA-1024 is just laying around in their files somewhere, the employees who know about it sworn to secrecy?
For all intensive purposes, "whom" is no longer a word. That begs the question, "who cares"?
Terraflops/second?
A trillion floating point operations per second per second?
How upsetting.
They should have used one of the top 500 to host the list of the top 500!

No kidding, Cray always has the coolest looking systems. The Connection Machine was pretty cool too, if I recall, it had 1000's of LEDs in a big matrix showing what was going on inside it, which was mighty purty (I've seen pictures).
The elxsi MBOS (Message Based OS, amazing I can remember after all this time) was able to run multiple OS's on top of it at the same time. It was the first partitionable system I'd ever heard of. Funny that's coming around again today - both directly (like IBM 690s) or indirectly (like VMWare). Kind of handy to be able to boot a virtual OS to do some testing. Too bad they folded and went to Singapore.

Wouldn't it make more sense for processors to be rated based upon their FLOP count? I mean; buying one base upon MHz is like buying a car based upon it's rpm rating.
And is there any program (preferably linux) out there that will do a benchmark test on my computer in FLOPS?

It's number 90 on the new list (was number 85 when it first came out), is entirely self-built by members of the theoretical astrophysics group here at LANL, and (in re: to a comment below) we've even been able to convince LANL to categorize it as a single computer, instead of 294 smaller ones.

Um, I'm only a novice Japanese student, and I might have totally mangled this, but let me try to explain as best as I understand. If you know this stuff a lot better than I do, feel free to correct me; I'm finished with my classes and am trying to learn the language on my own now. Anyway:
:) It's very difficult to translate a lot of Japanese to English (well, for me anyway :). I'm surprised Babelfish does so well but when particles like this are a little ambiguous, it totally fails, which of course is the case at least half the time.
This is a Japanese adage which basically means "pearls before swine". The 'ni' in this particular case is, in english, more like "to" than "in"; it has multiple meanings. So, it's more like "gold-coins to a cat". Or it might be more like "gold coins at the location of a cat" which could be more like "gold coins before a cat". Here's the link I read about it at.
Was that your translation or did you use babelfish? I only ask because it sounds kinda like a babelfish translation. They can be pretty funny

Near the bottom of the list are a bunch of clusters made with 100 odd workstation class machines on ethernet, so a well wired office of engineering computers could probably make the list. Guess that's why Beowolf is so popular and why US export restrictions are so retarded (not to mention that the Japanese or Europeans will be happy to sell most countries a supercomputer for "oil exploration" or the like) (yes I realize that oil exploration from 3D seismogrophy is a legit use for a supercomputer, it's just that many countries that would want to get their hands on large computers for military purposes would also be able to disguide it as an economic purchase of that type.)

Also, Windows wants to run on something that looks at least *vaguely* like a PC. Some of these supercomputers look like PCs with odd network peripherals underneath them, some look like clusters of multi-processor shared-memory PCs (sometimes with too many processors for Windows) with a communications layer between clusters. Some of these work ok for Windows (SETI, for instance), while others are too different.
Also, the communications patterns between nodes and between common applications programs are highly critical here. The tighter the coupling, and the finer-grained the parallelism, the harder it is to fit into whatever framework the operating system provides. Loosely-coupled systems can work just fine on Microsoft; very-tightly-coupled systems need more hacking. And a large part of the Windows plaform is really focused on desktop graphics applications, which simply aren't relevant for supercomputers. (There are people doing clusters with game consoles, such as the Sony Playstation, but that's because they want to use the fast parallel CPU in the graphics engine, not the boring CPU.)

But the big floating-point applications that NSA has are likely to be signal-processors like Echelon which are trolling for voice signals and such, which is a good match for large numbers of scalar processors. How tightly they're integrated depends on the conveniences of signal collection, which is beyond my ability to speculate credibly :-)

The NSA also does statistical analysis of encrypted data, looking for anomalies that provide valuable clues for cryptanalysts. That can suck up a lot of floating point horsepower.

HP claims to have 159 of the systems in the top500, but doesn't talk about the fact that over 100 of them are for computer architectures that HP has declared dead, those based on DEC's Alpha and HP's PARISC.
HP's future is based on commodity chips where the only advantage that HP has is size and the cash to support the significant amount of upfront large scale system integration. And I'm sure that a lot of the folk who have done this work in the past are headed for the chopping block as HP finishes off the parts of DEC that Compaq didn't.
