I suspect the time frame is longer than that, although the window-of-opportunity for the money is apparently on the order of days, and a quote before the procurement meeting would help. Any ideas? Who's good? What it should cost? Thanks!" If you're quick, maybe you can become the world's newest manufacturer of custom beowulf clusters.

      Be warned, Atipa was recently bought by MicroTech computers, and they are sometimes known for not being very good about support, or providing decent equipment. I know that Microtech fired a whole bunch of the Atipa employees though. Before this though, Atipa was looking very good.

      If you are interested, SGI can sell you turn key beowulf solutions also. You can also go to http://www.beowulf.org and they have a list of commercial companies that provide beowulf clustering solutions.
      • By far and away MicroTech is the sleaziest of all possible computer vendors. They only really have money, because for a while the state of Kansas dictacted that computers must be bought in state. Their PC's break after about 1.5 years and they try to wiggle out of complete support contracts, which would have 1.5 years left on them by saying stupid shit like memory is too expensive so we're not going to replace it (even though they are contractually obligated to do so). And they're laptop support is utter crap. You'll call about a failed laptop. Trace the problem down to bad memory (himem.sys won't even start because it can't access sections of memory), request to have it replaced, but they'll send it back saying Norton anti-virus fixed the problem. But the problem pops up in the returned box. Oh yea, and you can't find drivers for anything. Sorry to be so mean, but I've really had more than I can take of Microtech.

      This summer I was employed at a finite element analysis company in Philadelphia, and I designed, budgeted, and built a 10 processor AMD System (Octavian) based on gigabit ethernet, 1.2 Gig MP AMD chips on Tyan mobo's with half a gig of RAM per node, and it did not cost more then $13000 plus some setup time. (This was with a gigabit switch, etc AND the current cost with dropping prices would be less then $10000) The computer was designed to run LS-DYNA (a Livermore software finite analysis program) and it has not let them down.

      Here are some benchmarks:

      Octavian Benchmark runs
      as of 8/17/01

      6 Processors: 34 minutes
      10 Processors: 24 minutes

      Analysis of the execution throughput indicicates a linearly increasing speed
      (1/wall clock time)

      And here is a review of the results:

      the cluster is performing BEAUTIFULLY, and we have been crunching problems on it pretty much nonstop since it was brought online. It has really saved our butts, as we could never have met some key project deadlines without the speed. I've included some bechmarking stats below FYI for a contact problem that took only 24 minutes to run on octavian using 10 cpus. The comparable time on our $50K dual CPU octane workstation is 3 hours and 26 minutes, which translates into a speed up of 8.6 times for about 1/5 the cost.

      So, What I am trying to say is build the thing yourself. You will know much more about the system, and you will be able to install any software you want to without having to deal with "customer service". Also, it will save you a bundle as a turnkey solution is nearly 3 times the price. (Even if this cluster was built with Myrinet it would still be far less then any of the pre-built solutions) Lastly, design the cluster for what you need. If your problems involves lots of RAM, then spen money there. If CPU is the bottleneck spent money there. If communication is the bottleneck....

More often than not the principal investigator will then suddenly remember that proposal by some group member to spend big bucks on some obscure (for him/her anyway) technical thing and get on the bandwagon. At that point things need to move fast...

      As someone who actually owns a quad Xeon (Intel Sitka 4x400MHz 1M cache) and is building 2 more for a cluster... the answer, as always, is "depends". It all depends on what the intended use is. For a embarrassingly simple parallel processing job (aka running 20 seti@home jobs) the price/performance ratio can be quite poor. Prices are definately down, but the motherboards and RAM are still fairly expensive (typically you need EDO ECC DIMMs with high end server boards, not the cheap SDRAM). You can pick up several 1GHz barebones Athlons for the same price and run the data serially thru each at a faster pace.

      On the other hand, if you have a true multi-threaded, highly integrated task that requires high inter-process communication, separate boxes are a poor choice. Something like a large relational database or multi-dimensional vibration calculation wherein each calculation requires knowledge of it's neighbors motions, is far superior on a multi-CPU box. Unless you implement an expensive Dolphin/Myrinet network, the process communication alone, be it over ether, SCSI, or FC, kills a multi-box solution. Not to mention the fact quad Xeon boxes typically take 4-8GB of RAM so everything is always local.
  • You can't buy (or make) a x node cluster and expect to run Quake x times faster : parallel processing machines require parallel programming. This is usually means that you want a cluster to solve a particular problem, that the problem is specified, the parallel application is properly designed, architectured and implemented.

    Would 2 Quad boxes be better than 4 duals? I don't think they're *much* more expensive (per slot)and administering two boxes might be more practical than four. The performance gained by eliminating communications overhead may make for a desirable price/performance. I don't know; I was just thinkin'...
    • Two quad boxes would theoretically outperform 4 duals, because you have more bandwidth between the processors. Of course, if it's not a parallel task in the first place, extra processors won't give you anything.

      You're wrong about the price though. Two quad boxes would be _much_ more expensive than four duals, because you can no longer use your traditional PIII/Athlon processors. You have to up it to an Alpha or Xeon. Both those processors and their respective motherboards cost 1.5-3x the price of PIII's, for the equivalent number of processors.

      The point of Beowulf clusters is to be able to put bunches of computers that are not very powerful in and of themselves together to make something really powerful, so using quad processor boxes kinda defeats the purpose. The ideal price/performance balance is two processors per box, and this is easy to see by looking at the commercially available solutions.
    • Probably depends where most of your collisions take place, but I do know that when you have multiple Pentiums (not sure on Xeon based), that when one CPU is accessing the memory or I/O, the other has to sit and wait. That's one of the big benefits of a multiple Athlon system - both CPU's can access memory simultaneously.

    • wow, you sound like my brother... are you adopted?! Beowulfs in lieu of paintball, and in charge of pumping up the nerds...like looking into a nerd-mirror.
    • Most of the apps for Beowulf clusters tend to be scientifically oriented apps. It really comes down to there being only certain kinds of problems that can be broken down into parallel processes that can be executed concurently, then the answers "recombined" at the end to get the result.

      IIRC, Mosix allows for using the machine as one large machine, essentially allowing each process (or groups of processes) a single CPU, but funneling the result back to the main controller, so to the user, it looks like one large machine. This is different from a standard parallel processing Beowulf cluster, which behave like classical parallel processing machines.

      For that domain (parallel processing), aside from coding your own stuff (hard to due, even if you are a master coder, from what I understand - due to having to understand what classes of problems can be broken down into parallel tasks, and then actually applying that knowledge to real tasks), there is one application that would prove to be "fun" - Ray Tracing.

      Fortunately, POVRay has a paralleled version available, for Beowulf clusters. I don't have a link, but I know it exists (heck, you can probably get it at the POVRay site).

      One other disclaimer: Everything I have said should be interpreted as "coming out my ass", simply because I have no experience at building or using Beowulf clusters or any other parallel processing architectures. Most of what I know about them have come from /. discussions, various web sites of Beowulf cluster projects, books, and magazine articles (as well as one funky book I picked up at the library detailing programming in Fortran for a Connection Machine - eeepp!). The POVRay stuff is true, though...
      • As much fun as rendering seems over a large network, if you are really doing any major rendering and you don't have Cray-linked SGI's .. you are better off treating it as a NOW (network of workstations).
        The POVRay rendering dropped off at 8 procs or so, if i can remember correctly.

        We render a hand full of frames per box and do this on several boxes. This keeps the network overhead between machines low.

        Sometimes when people talk about beowulf, what they really mean or really want is just a bunch of managed computers running tasks. If the task can be broken down at submission time, like most renders, then take advantage of a NOW.
        • Good points.

          In a way, from what I understand, this is kinda what Mosix does for you, automatically, and and thus different from a true Beowulfed parallel processing app.

          I guess it also depends on if you want to learn parallel processing techniques, or if you are trying to get a job done.

          The drop off I would imagine is due to slow interconnects among the nodes - I am sure there would be better gains the higher speed your interconnects were.

          Anybody know how the POVRay for Beowulf machines really works? Does it break the viewport into n sections, handing each section to a different node, or does it process multiple rays (ie, a node per ray), or what? Anybody got a link on this?

    • > This is what clustering is all about, turning cheap off the shelf systems into a super computer.

      No, this is not what clustering is about. Beowulf, specifically, is about gaining raw performance without concern for stability or fault tolerance/redundancy.

      There are many other uses for and of clustering; not all of them are concerned with speed (your super computer quotient, if you will), less of them are concerned with saving money.

      Granted, the original post specifically mentioned Beowulf, but from that one should not assume that clustering == Beowulf.

      But get this: I built the whole thing for $170 per node . That's everything, shipped to my door.

      They load the kernel off the floppy and grab the NFS root from a fileserver I've got set up, so no need for hard drives. Granted, there's a bit more network and memory overhead (both /var and /tmp sit in memory), but I can buy more nodes from the money that I've saved on hard drives.

  • How to make a Beowulf cluster in 2 hours for free.

    1) Find a single machine to use as cluster server.
    2) Install some linux (I prefers debian.)
    3) Set it up as a diskless client server.
    Debian have some diskless packages, but I prefers
    to use cluster-nfs form clusternfs.sourgeforge.net
    it makes it easier to maintain the system.

    you can find a howto for setting up a mosix cluster
    at the cluster-nfs site dropping the mosix stuff and installing
    mpi and pvm should do it.

    4) To use your groups computers as diskless nodes
    go to http://www.rom-o-magic.net make some boot floppies
    and use them to boot against your server.

    5) Have fun with your new Beowulf cluster.

    Whenever you need a Beowulf cluster just boot up
    via the floppys.
    In this setup it is only one the server you need to maintain.

    oh wait. Never mind.
  • Honest to goodness curious question that I'm sure the slashdot crowd could answer: what exactly does "turn-key" mean here?
  • Ah yes, you must work for the government.
    Yes with the fiscal year ending we all have lots
    of money to spend this year or we'll loose it
    next year. Don't you love working for the government?
    Sometimes I think the only job in America that
    is better than working for the government is being a domestic cat.
  • Has nice setups. www.wsm.com
  • Try Aspen Systems [aspsys.com] or Einux Network Solutions [einux.com]

    Not sure how "out of the box" the Einux ones are, but you can get a 10 node dual-Athlon setup for around $25k.
  • You might want to check around to see what companies locally might make them. IBM clusters are avaliable through a number of smaller companies, most will ship them just about anywhere in the country, but you can save a ton on freight be finding one local. There is one in Houston, TX that I know of if you are in the Texas area, that is PCPC, Inc. (www.pcpcdirect.com) that custom configures and builds IBM clusters

  • Microway [microway.com] also sells these toys. If you want Alpha, look here [microway.com]. If your budget runs more to Athlons, look here [microway.com]. Unfortunately, you will have to choose between 8 and 16 CPUs on the low end here; they don't have a 10 CPU Athlon cluster.

    You should think a bit about whether the extra abilities of the Alpha boxes are worth the extra bucks for your application. One thing which I think that I remember about the Alphas is that they use a crossbar switch to link the several processors on a motherboard to memory, et cetera. This should give better throughput. They also have huge caches which should help with big matrices. I think that if you have lots of little problems which should be run in parallel, more nodes with lower price and capability per node might be the way to go.


    I remember back in the days of the XT, Microway used to sell math coprocessor and video boards for PCs which cost more than the box you hooked them to, along with high-grade compilers which would put that hardware to work. They were once the place to get hardware and software for doing seroius number-crunching on a PC.

  • but it may take a while before it gets shipped (grin)

  • Buy ten machines, and build it yourslef? I mean.. that's all a beowulf is... it was a project to work on using off the shelf hardware for parallel processing.

    DO you have some app that needs it? I mean, you can't just run anything....
    Did some department just come up with some app already designed with the PVM libraries or something?
  • or was it so obvoius that he's asking this for those reasons?

    I'm not complaming - i'm just finally glad to see /. as something USEFUL.

    fight on!
  • But am I the only person here to think "working on my morning M&Ms?"
  • I've seen a few stories about researchers looking for a cheap, quick, and powerful cluster for their research purposes who decided to go with Apple hardware. One group got an 8-node iMac cluster up and running in less than a day (which I can't find the link for.. sorry).

    A quick search of Apple's site actually mentions clusters [apple.com] [apple.com]. Perhaps 10 dual G4's would suit your needs?
