Top 500 Supercomputers

Anonymous Coward writes "sendmail.net has a piece on the new Top500 list of supercomputers. 'So who came out on top? Well, three US Department of Energy machines have taken spots one, two, and three to lead the list: ASCI Red (manufactured by Intel) at Sandia National Labs in Albuquerque, ASCI Blue-Pacific (IBM) at Lawrence Livermore Labs in Berkeley, and ASCI Blue Mountain (SGI) at Los Alamos. These are the only three systems to exceed 1 TF/s on the Linpack benchmark, and represent 7.4 percent of the total Flop/s on the list.' The story notes that the average growth rates for the list exceed the number set by Moore's Law. "

    Mere "flops" is a very specialized metric. It biases toward low-level programming or calculations that are easy for the programmer to partition. The more the programmer must know about the solution to the problem in order to write the software to solve it, the fewer problems get solved.

    A better metric for computation power is given by this formula concerning the memory heirarchy:

    bandwidth*size*speed where memory

    bandwidth is the average speed at which data streams to or from memory

    size is the amount of memory

    speed is the responsiveness to random access

    What the massively parallel processor advocates frequently forget is that locality of reference is an expensive assumption. A similar mistake is made by memory heirarchy advocates. For example, many systems where CD-ROM jukeboxes were included to expand the size of the memory the architects overestimated "locality of reference" and therefore underestimated the profound impact that moving the robot arm around would have on latency. Such designs are convenient for the hardward designer who wants "good numbers" and a nighmare for advanced software application that needs unpredictable access to lots of information at a high rate in order to get the solution out of the machine before the solution is obsolete. The operands have to come together through that maze of wiring. If you have partitioned the memory, it profoundly affects both latency and bandwidth. The critical thing is to allow _shared memory_, and that means advanced memory control units.

    Seymour Cray kept ahead of the supercomputer pack for more than two decades by focusing his best talent on fast, high bandwidth memory control units and building the biggest semiconductor memories to match.

While cluster-based projects have firmly established a foundation upon which small- and medium-scale clusters can be based, the current state of cluster technology does not support scaling to the level of compute performance, usability, and reliability of large MPP systems. In contrast, large-scale MPP systems have addressed the problems related to scalability, but are limited by their use of custom components. In order to scale clusters to thousands of nodes, the following must be addressed: Use of non-scalable technology must be bounded or eliminated. Technologies like TCP/IP, NFS, and rsh have inherent scalability limitations. Scalable management and maintenance is critical. The complexity of maintaining the cluster should not increase as it grows. Usability of the machine is critical.

      Brilliant! -- and to think, all those "experts" they have at DOE didn't notice this...

      Think about this for just a sec... If you take a fairly communications intensive benchmark (such as linpack), which clusters do you expect to give you the best "bang for the buck"? We know that performance will be a function of 1) processor speed, 2) number of processors, and 3) communication speed/bandwidth. Obviously, those clusters with the least comms overhead will have the advantage. Now, do you expect a machine with 10^2 procs to have the same comms speed/bandwidth available per processor as a machine with 10^4 procs?

      So on one hand, you could say ASCI Red is an inefficient POS, and with respect to a benchmark like linpack, you'd be somewhat correct. On the other hand, given a less communications-bound benchmark (like a prime-number sieve, or something distributed.net-esque), ASCI Red would look a lot better.

      Now this brings about one more topic: Why do they use linpack as a benchmark, and not something with fewer comms? For "Real-world" applications on supercomputers (as they apply to science/engineering), most of the computational effort is spent doing operations on sparse matrices (i.e., matrices that are mostly zeros). One way of handling these operations is to do them in the same manner as a dense matrix (multiplying/adding all the zeros), which is horridly inefficient. The preferable alternative is to spend a great deal of time "looking" for work to do on nonzero entries. This "looking" is faster than performing all the unnecessary computation, but obviously implies more communication. Thus, putting the machines with more processors at a disadvantage.

      Happily, though, there are plenty of people with computational needs that aren't terribly comms intensive, who would rather have the 9000 processors than awesome comms speed, because for us, that's what makes our codes run faster. (That and we don't sit in a queue all day waiting for a block of cpu's to free up)

      Quake Analogy:
      Your pals across the street share a T1 and play on the same server with the same number of people all the time. With their nice ping, they each average 1024 frags/hour (gotta be even powers o' 2). Now you have a LAN party, and 64 other people (of equal "talent") get on the same server, abusing your T1, lagging it out, and you each average 16 frags/hour. Thus, looking at the first situation, they look like a butt-stomping, fragging machine. Whereas in the second situation, you look like a bunch of gay pansys. However, is it really fair to say that you're a worse quaker just because your ping sucks compared to that lpb across the street?

As the adoption of Linux systems expands across all marketplaces, Ohio scientists, educators and engineers can begin to use the state's largest Beowulf cluster as a starting point into scalable high-performance computing.

    "Presenting new technologies, like the 128-processor Linux cluster, to Ohio is central to OSC's mission," said Charlie Bender, executive director, OSC. "This type of project provides the center with an opportunity to expand its role as a statewide resource by bringing even more scalable computing power to Ohio's scientists and engineers. This collaborative project with SGI will help us assist researchers using Linux at their desktop to use the high-performance computing systems found both at OSC and the National Science Foundation supercomputer centers."

    Beowulf clusters like OSC's are specialized supercomputers that are gaining popularity in the technical and enterprise computing market because of their high performance at a relatively low cost. Beowulf clusters are used for solving very specific types of problems through what is known as parallel decomposing.

    Ohio's research community will be able to access the Beowulf cluster through OARnet, a division of OSC. OARnet is the state's high-performance network providing Internet connectivity to more than a million Ohioans. As a leader in computing and networking, OSC is a state-supported resource for Ohio's scientists and engineers with an impressive array of machines and visualization equipment including Cray T3Etm and Cray T94tm supercomputers, two Origin 2000tm servers and several Silicon Graphics® 320 and Silicon Graphics® 540 visual workstations.

    "SGI continues to pave the way for highly scalable, parallel Linux solutions in both technical and commercial markets. Our cluster solutions offer the unique capability to scale both high and wide for the right price-performance to meet our customers' application and budget requirements," said Jan Silverman, vice president of marketing, Computer Systems Business Unit, SGI. "Together with OSC, we hope to focus our attention on building better management tools, workload balancing and high availability for these cost-effective clusters."

    The OSC Linux cluster will consist of 32 SGItm 1400L servers, each with four 500 MHz Intel® Pentium® III Xeontm processors. Preloaded with the SGItm Linux® Environment with Red Hat® Linux 6.0, the SGI 1400L server is an enterprise-class server designed to fulfill customer needs for comprehensive and cost-effective solutions that merge SGI's expertise and innovation in scalability, bandwidth and performance with industry-standard components and operating systems.

    The number listed in the Top500 for processors is a bit mis-leading, this is in fact the number of nodes. The Hitachi nodes are made up of a number of processors, each with pseudo-vector optimisation (allowing them to miss the cache when loading large memory blocks).

    In 1965, Gordon Moore was preparing a speech and made a
    memorable observation. When he started to graph data about the
    growth in memory chip performance, he realized there was a striking
    trend. Each new chip contained roughly twice as much capacity as its
    predecessor, and each chip was released within 18-24 months of the
    previous chip. If this trend continued, he reasoned, computing power
    would rise exponentially over relatively brief periods of time.

    Moore's observation, now known as Moore's Law, described a trend
    that has continued and is still remarkably accurate. It is the basis for
    many planners' performance forecasts. In 26 years the number of
    transistors on a chip has increased more than 3,200 times, from 2,300
    on the 4004 in 1971 to 7.5 million on the Pentium® II processor.

And that level does not get to see the "sensitive" code yet. I help tune these codes for performance, and am not allowed to see the most sensitive sections that contain the cutting edge algorithms.

These processors are highly specialized and much more expensive than regular processors (G4 notwithstanding ;-). Our humble Cray J90's CPUs, for example, can process 64 array elements (each element is an 8byte word) with each vector command making it very fast for matrix-style calculations. As far as I know, the LINPAK benchmarks vectorize quite nicely, thus, giving vector machines an advantage.
    Unfortunately, since SGI sucked all of the life out of Cray Research, all of the recent developments in vector hardware have been from Japanese manufacturers, thus leaving many US gov't agencies without big vector iron.
