SGI & NASA Build World's Fastest Supercomputer

GarethSwan writes "SGI and NASA have just rolled-out the new world number one fastest supercomputer. Its performance test (LINPACK) result of 42.7 teraflops easily outclasses the previous mark set by Japan's Earth Simulator of 35.86 teraflops AND that set by IBM's new BlueGene/L experiment of 36.01 teraflops. What's even more awesome is that each of the 20 512-processor systems run a single Linux image, AND Columbia was installed in only 15 weeks. Imagine having your own 20-machine cluster?"

      a) obtain space. Usually, raised floors, rack systems, with adequate HVAC for the huge thermal load you're about to throw into a few racks. For collocation, it'll take some time for your provider to wire together a cage for your installation, especially if you need earthquake bracing. Expect two weeks.

      b) obtain power. For our production environment, each redundant power supply needs to be served by a separate circuit. The way most redundant power supplies seem to work is they split the load between the two circuits - so each circuit has to be able to handle the full load. Supercomputers may not have the same production requirements, but probably - lost cycles is lost money. Anyway, this is contracted out in almost all cases - expect two weeks minimum. b is usually dependent on a, some providers may perform buildout concurrently. Not much of an issue if you use Equinix - very cool overhead power systems (imagine a very large power track system, with drops wherever you need them).

      c) obtain equipment. delivery time from a week to 5 weeks.

      d) it takes some time to unbox 100 machines and rack them. Throw people at it, or throw time at it.

      e) network infrastructure. do it yourself, you're using a lot of time to cut cables to length. contract it out, you get very neat work, at expense, and usually only to rack-specific patch panels. Buy lots of different length cables and forego contracting, you save time, but you end up with a cage that looks like hell that's easy to snag.

      f) configure 100 machines. This is probably the easiest part - set up your DHCP server and PXE boot server, roll up some kickstart system, and deploy - 100 machines can be done in a few hours. There's obviously some setup and thought that needs to be put into the installation scripts, but that can be done ahead of time.

This introduces an overhead into the program, and the amount of overhead depends on the interconnect.

      Yeah, this was the idea behind the CPlant at Sandia some time back. Each node was an Alpha box with like 1G of memory, but only 256M was made available to Linux directly. The rest was a big block of contiguous memory with only very simple services (no paging, etc. but it did have 'pipes' for IO like HDD access, network access, services for IO (printf and such) and the like. When a 'parallel app' was run, it existed in this memory block and ran outside of Linux's sheparding for the most part. It had direct access to the high speed networks (Myrinet) and such without much/any OS overhead.

      Doing this, they had the flexibility of running Linux on each node for network services (netboot, ftp, ssh, etc) but had the benefits of having basically dedicated hardware with a custom OS (not Linux) that had a minimum of overhead for computational processes all on one node and running simultaneously.

      The nodes share main memory, but are not cache coherent in L1 or L2. It really is an interesting design. They trade off a lot for maximum efficiency, with respect to space and performance. I suspect power was mainly a concern only as it affected the maximum possible density.

      Lets say you have N processors, each capable of executing I instructions per second. Your total theoretical throughput would be N x I. However, this would only be the case if the system is 100% parallel, and no processor needed to communicate with any other. Rarely the case.


      In practice, the function of performance to processors follows a distribution that looks a bit like a squished bell curve. As you increase the number of processors, the performance gain decreases, reaches zero, and actually becomes negative. At that point, adding more CPUs will actually SLOW the computer down.


      The exact shape and size of the curve is partly a function of the way the components are laid out. A good layout keeps the amount of traffic on any given line to a minimum, minimizes the distances between nodes, and minimizes the management and routing overheads.


      However, layout isn't everything. If your software can't take advantage of the hardware and the topology, then all the layout in the world won't gain you a thing. To take advantage of the topology, though, the software has to comprehend some very complex networking issues. It has to send data by efficient pathways.


      If connections are not all the same speed or latency, then the most efficient pathway may NOT be the shortest. This means that the software must understand the characteristics of each path and how to best utilize those paths, by appropriate load-balancing and traffic control techniques.


      If you look at extreme-end networking hardware, they can be crudely split into two camps - those where the bandwidth is phenomenal, at the expense of latency, and those where the latency is practically zero but so's the bandwidth.


      The "ideal" supercomputer is going to mix these two extremes. Some data you just need to get to point B fast, and sometimes you're less worried about speed, but do need to transfer an awful lot of information. This means you're going to have two physical networks in the computer, to handle the two different cases. And that means you need something capable of telling which case is which fast enough to matter.


      Even when only one type of network is used, latency is a real killer. Software, being the slowest component in the machine, is where most of the latency is likely to accumulate. Nobody in their right minds is going to build a multi-billion dollar machine with superbly optimized hardware, if the software adds so much latency to the system they might as well be using a 386SX with Windows 3.1

      Commodity linux clusters are not the only kind of cluster out there. SGI has been building clusters since the late 80s. Their first super-computer product, the power-challenge clusters, were 16 and 36 way SMP boxes clustered together with hippi. Remember terminator-2 and jurasic park? Those were rendered on clusters of crimsons and indigo workstations. They may have called the NOW(network of workstations) instead of beowulf, but it was the same thing.

      As for linux, they stepped towards linux about the same time IBM, HP, and Oracle did. They've contributed a LOT of code to linux and GPL products. They have transitioned the bulk of their product-line to linux in the last year or so, but they started that process five years ago. They have a LOT of legacy customers and legacy code to transition. Linux is a stable and high performance OS, and it would be that way without SGI, but it got there a lot faster because of SGI's efforts.

      Furthermore, SGI doesn't give a damn (nor does anyone else) if slashdot loves them or not. They care if nasa, boeing, the US navy, BP, and NBC love them. These are the people with the bucks, more interested in a solution to a problem than to any license or technology.

      The real reason that SGI doesn't get the credit they should is much simpler: They put a crappy scsi controller on the mezanine-bus of the challenge-S server in 1994. In the early 90s SGI was the darling of the multi-media world. Their workstations were everywhere, and they made pretty cool servers too. They were poised to ride the same dot-com wave that SUN rode. They introduced a single-CPU server called the challenge-S, which was derived from the indy workstation. It was reasonably speedy and quite affordable (for a unix server of the time). The scsi controller, however, was quite prone to failure. They developed a bad reputation. While the world was busy buying sun servers hand-over-fist, they avoided SGIs except in the technical/defense/media markets. That legacy shaped the company into what it is today: a niche player, struggling against giants like IBM and HP, in the relatively small market for high performance computers.

So I agree with you that software can hobble the best multi-processing system, but I think you can scale higher even in hardware given the right network topologies and communication paths.

      The path-traversal algorithms for interprocessor communications was fairly cool and tolerant of partial link breakdowns. Each message passed had its ultimate destination address as the prefix. The receiving processor only had to bit flip one or more bits on it to choose its current path and send the message along the way.

      If there were no hyper-cube-link outages, then a message would have to traverse at most 10 (ten) edges to get from any node to any other node. If there were any missing edges in the system, the network could route around it, because there would be up to 2^10 paths to get from any node A to any other node B, even more if you allowed paths of greater than 10 steps (such as hitting a network-edge outage as soon as it occurred.)

    The ultimate solution z is limited by the speed x & y can be solved. You can have an individual computer solve for x and another for y in parallel. But no matter how many more computers you add, none of them can solve z until x&y are solved first, and none of them would speed up the computation of x&y.

      At the high level, things will always look similar. You can write Fortran and have it compile regardless of whether you're working on a RISC machine or a CISC machine, a register-rich machine, a register-poor machine, a three-operand R-R machine or a memory-based stack machine. The only thing you _might_ notice is changes in the communications topology, because it changes how you'd split up the problem, but that's not a processor issue (it's a network/interconnect issue).

      That having been said, there does seem to be a convergence within processors themselves. Much of this stems from very fundamental design constraints. It's easier to pipeline instructions if they only do one thing, so instruction sets either get RISCian or get translated into something RISCian. It's easier to access local storage instead of non-local, so everything has a register file and a cache hierarchy. There's demand for parallel execution of SIMD-style computations, so most things support that. Everything works better if you have an unbroken stream of independent instructions, so processors try their hardest to mask latency of things like branches and memory accesses through speculation, and re-order instructions to mask dependencies. The only technology that wasn't really used much for this was symmetric multithreading (SMT), which gets you a stream of independent instructions by pulling them from multiple threads, but this has finally trickled down into the mainstream. So, processor cores contain the same kind of fundamental feature sets by necessity. We're going to continue to see this, for example with the emergence of so many chip multiprocessing (CMP) offerings, where putting multiple copies of a core on die is a better use of space and power than trying to build (and feed!) a more complex single core or adding more cache.

      The devil is in the details, though. The instruction set architecture of x86 offerings is a very large mess with several inconvenient anachronisms, which takes working around. The PPC ISA is a bit cleaner in that regard, but I'm sure it has its own quirks. Itanium (1, at least) struck me as an experimental test bed for every bizzare instruction set feature they could think of, some of which may even pan out. If there's a chip that's pushing architectural boundaries, that's probably it (pity that it didn't help it much).

      However, unless the nature of the tasks being asked of a microprocessor changes drastically, or unless someone comes up with a really fundamentally different way of structuring data flow for problems, processors will continue to look more or less the same, even if the underlying fabrication technology ends up changing drastically (which I doubt it will in the next decade, at least).

      I'm less excited by a supercomputer with 10k processors than I would be by one containing as few as 64.

      The problem is that if you can build a supercomputer with 64 processors, you can build an even better supercomputer by wiring a bunch of 64-processor nodes together. Yes, you're increasingly communications-bound, but there are enough (useful!) problems with relatively low communications overhead for this option to still be attractive.

      Interestingly, this is increasingly the case for single processor machines as well. They're getting multiple cores on-die, because both increasing the complexity of a superscalar core and devoting added real estate to cache have reached diminishing returns. This trend will only continue.

    Weather prediction, it turns out, is *not at all* like playing chess. Chess is a deterministic linear process operating on rigid, unchanging rules. There is always a "best move" for every board state, which a sufficiently fast and capacious database could search for. Weather is chaotic, a nonlinear process. It feeds back its state into its rules, in that some processes increase the sensitivity to change of other simultaneous processes. Chaos cannot be merely "solved", like a linear equation; it must be simulated and iterated through its successive states to identify more states.

    Of course, we're just getting started with chaos dynamics. We might find chaotic mathematical shortcuts, just like we found algebra to master counting. And studying weather simulation is a great way to do so. Lorenz first formally specified chaos math by modeling weather. While we're improving our modeling techniques to better cope with the weather on which we depend, we'll be sharpening our math tools.

      Chess is not linear. What are you talking about?

      In its most general sense, linearity implies superposition of some sort. This is not present in chess. Rather chess can be modeled as a nonlinear dynamic program, not a linear one.

      The distinction between chess and "weather" is that chess takes place in a discrete, countable domain. i.e. it is possible to enumerate and count up all of the possible moves. Furthermore, it is somewhat practical to approximately enumerate all of the concievable moves (e.g. n-step look ahead + heuristics) given modern computing technology.

      Weather, on the other hand, is described by a set of nonlinear partial differential equation (i.e. Navier Stokes) over the globe, which is generally modeled as an uncountable domain (i.e. S^2, which could be mapped to a subset of R^2). A primary problem in weather is that we do not have the ability to observe some of the key factors affecting the dynamics---namely the ocean-atmosphere heat flux (oceans hold a lot of the heat so that this is important). Therefore, weather prediction relies on a lot of indirect modeling/speculation of these factors.

      It is true that the nonlinear models that match with our physical understanding tend to be mathematically challenging (one of the open Clay prizes is to simply prove uniqueness and existence of solutions to the Navier-Stokes eqns). Further, I agree with you that environmental sims are an appropriate app for mega-computing (no controversy there, note that the Japanese supercomputer is called the 'earth simulator').

I suppose that by modeling chess as a branching tree of possible next states deriving from the current board state and the rules, it's not exactly linear (branches). But that branching space can be sorted and searched linearly. That approach to "solving" chess in the early years of computer science was the basis for much of our general purpose database algorithms later. I appreciate your information of the formal mathematics of chess models.

Of course there were delays and problems and more delays while SGI announced MIPS-and-someday-Itanium systems and tried one Pentium system after another, at least having the sense to drop Windows NT for Linux in the process. Finally, in early 2003, having apparently failed to ever sell even a single Itanium system, mind you, SGI shipped Itanium 2 systems.

Even though SGI still has more model lines with MIPS processors in them, and has committed to keeping MIPS around until at least 2006 (and good luck getting rid of it then at this rate), Intel got SGI to sell its soul for a basket full of promises. Either SGI loathes Intel for this but is afraid to do anything about it (after all, switching architectures again would be a pain, even if they are now a Linux company and Linux runs on everything), or SGI has a nasty case of Stockholm Syndrome and thinks that Intel is actually on its side. Anyway, SGI has tied itself to Itanium for over a half-decade now, even if it didn't ship jack for most of that time, and it's unwilling to change horses.

    The answer here is "complexity". I do some scientific computing (have done chemistry, then materials science, now doing photonic devices) and there's always more you want to be able to consider. Of course, the best I've used is an 8-processor SGI machine (although that one was a bit old - I think the 2-processor opteron system I'm using now is actually better). But especially with the materials studies, ideally we wanted to do everything with full quantum-mechanical calculations. which turns into gigantic matrices, even for a system of 100 atoms or so. And even then we put strict limits on what orbitals we consider and all that good stuff.

    Slightly more concrete example - right now with my photonics simulations (finite element) on my dual-opteron rig the max I can handle is about 180,000 elements (which means a (4*180000)x(4*180000) matrix with complex elements needs to be diagonalized, among other things), and it takes about half an hour for a standing-wave calculation. To do any time propogation, repeat same calculation in picosecond increments. And with the gridding I can do, for a 100 micron disc resonator in 2-D I have to use light at about 40 microns. To go to the 320nm wavelength these resonators are operating at, I'd need roughly 2 orders of magnitude more memory. There's also the time factor to be considered. As with any design process, one must iterate. Tweak a little here, run the program, rinse, repeat. How long are you willing to spend in this process before you feel something is "good enough"? The faster the computer spits the answer out, the more things you can try, and the more you can think things over and hopefully make it better.

    And this is a single component in what can be a fairly complex integrated-photonics chip. [And might I mention again I've been working in 2-D this entire time instead of doing a full 3-D simulation?] You give me the computational power and I'll use it. And I'm an experimentalist doing fairly basic research who just wants to check some stuff in the computer before sinking a lot of time and effort into fabricating a test device.

    On the other hand, I actually don't want to have one of the T100 supercomputers in our lab. That would mean I'd be spending all day writing code and designing complex simulations instead of in the lab getting my hands dirty.

    And as for the commonality of problems requiring such computational power, I think almost any sort of simulation can easily use it. Consider more terms (everything I've done to date is horribly linearized - let's see some more terms in the Taylor expansion) to account for nonlinear behavior, grid things up finer to get more accurate results, consider more possibilities when dealing with chaotic behavior... I would hope any good scientist would find the possibilties endless.

    Yeah, Irix is cool. The trouble is, SGI resisted the hardware change. They kept on betting on the wrong horse (MIPS). At the same time, Intel and AMD were beating the crap out of all other CPUs.

    Sun, can hold up to 106 processers in its Sunfire 15K product, or 72 dual-core processors in the E25K. SGI's Origin systems are equally large I believe.

    Actually, SGI makes 1024-CPU systems using the older MIPS/Irix architecture (the Origin and Onyx platforms), and 512-CPU systems using the newer Intel/Linux (the Altix machines). And that's what they make on a regular basis. Experimental systems are even bigger. Also, the Intel/Linux SGI systems are still very young and likely to grow a lot more.
    That's one order of magnitude above Sun.

    SGI is leading the single-OS-image market in terms of the size of systems.

IT seems like it is once every other week there's a new record, or report on a shot at one, or similar. Perhaps my memory is not so clear and I'm blowing it out of proportion - and I realize in this case the record has been seriously outstripped - but it still seems like a high number.

    In actual truth, faster machines allow to perform more iterations of the same algorithm in the same time. Each new iteration adds more precision to the prediction. So, faster computers do enable better predictions.

    That's all coming out of RAM though - but with that much RAM, why not?

    The reported record stands at about 4 seconds flat on a 32-way POWER4 machine, I think. This was at the start of the 2.5 series though, and there have been a crapload of scalability improvements since then.

    You probably can't beat that by much because most of the time would be dominated by the final link phase, which is single threaded. A classic application of Ahmdal's law.

    You must increase your exposure - I have used Sun 10K's with 64 CPU's in an image and we got 80% scaling, I've used 72 CPU images and and got 75% scaling and what was running- crappy Oracle parallel code. If you think 15K's, Superdome or Big IBM's max out at 8 CPU's you just haven't run in a large corporate data center. When you have 10's of thousands of processes these monsters scale well - with increasing overhead, of course, as they get bigger. Where you want to make the cutoff depends but it is way higher than 8 cpu's - I would say around 64 CPU's these days.

      Read my comment again. Most computers over 8 are not smp. It's too much of a headache to handle. I'm pretty sure Sun E10K's are NUMA. In fact, if I remember right, Sun bought the design for them from Cray since SGI didn't want to have a division selling sparc based boxes. I also remember seeing some SGI promotional material about the interconnects on the e10k beinf far slower than the SGI links. So yes, it's possible to build a very large SMP machine. But nobody really does it anymore. Even Opterons are using NUMA because it scales better and is much easier to build logic around.
