        Yeah, the kind of dream you wake from out of breath and with your heart racing. I, for one, am not yearning for a violent, ignoble death. But for those of you that are, it's probably easy to arrange.
    • They didn't even use a rack mount solution, they used regular Shuttle XPC SS51G Mini-PCs

      The question has to be... why? I've never understood why so many people build clusters with essentially desktop PCs. Haven't these people ever heard of the 1U rack mount case? Yes, it's a slightly more expensive inital outlay. But surely the cost savings in terms of floorspace and power/cooling for such a large volume would outweigh that in no time flat? Plus the Shuttle, like most other desktop cases, don't have the option of hot swappable drives. With the number of machines in this sort of cluster, drive failure is a major problem. The ability to just pull the failed drive out of the front to replace it would be a huge win.

      • Actually, you should be careful about the benefits of making the servers more and more dense! 1U servers are a pain to deal with for cables, and keeping the things cool. If you have the space, there is almost no real benefit to fitting the equipment into as tight a footprint as possible.

Okay, let's say $1550 CAD. Well with that I could buy a pretty sweet computer, actually a REALLY sweet computer, considering it doesn't need a monitor, or a fancy video card. I mean, we're just talking mobo, CPU, fan, RAM, network card, case. I could easily make a small cluster. In fact I was using small cluster at work in the summer. It has about 3 or 4 to begin with, and I bet the cost about $1500 CAD, but I'm pretty confident they were less. They were just 1.2 GHz Athlons. We ended up dismantling it (reducing it to only 2 units!) but still, it is cheap. I just don't see how they make that claim.

  • As much as I am a fan of cheap 'beowulf' custers, there is a certain issue which troubles me. In this case, the cluster in question cost less than 300,000$, a healthy sum, but much less than a large cray or sgi server would cost. Such clusters can be used for an array of activities, such as nucular bomb tests (one of the driving forces in pushing supercomputer technology is nucular weapons), or cracking encryption.

    Supercomputers are controlled by USA export laws, but powerful beowulf clusters can be made by anyone with a reasonable amount of money and knowlage. Since the software is free and of the shelf components can be used... wouldn't it be possible for terrorists to use open-source software to create their own supercomputers to test nucular weapons, crack American law and millitary encryption, ect... ?

    I believe this 'beowulf' techonology, as great as it is, could be possible dangerous to American interests. It is my hope that this software will soon be controlled by the American millitary and not be spread for free because I fear for the safety of my family and country (bless them both) if terrorists have access to supercomputing technology.

      • The physics behind nuclear weapons is well understood and widely published. It took a small town full of geniuses to figure it out the first time, (and determine that it's even possible) but no longer. They also designed a Uranium gun-type weapon and a Plutonium implosion-type weapon. The latter is muchmuch more complicated. Designing a gun-type Uranium weapon is trivial, and anly slightlymore difficult if you're restricted to pen, paper, and sliderule. (Granted I'm an MIT student, so I'm probably overestimating the amount of brain power available to a large terroist organization.) The difficulty lies in the tremendous amount of effort/electrical energy/sapce/time/money required to perform isotope seperation/smuggling without getting caught before you have the chance to detonate the weapon.
      • Cracking bulk ciphers is basically infinately parallelizable and does not require much communication bandwitdth at all. Beauwulf clusters don't gain you much. You'd get better performance running your cracking programs over V2OS, FreeDOS, or some other ultra-lightweight OS.

Planes filled with fuel, boats filled with conventional explosives, and dirty bombs are all very simple and can be potentially acquired by a single autonomous cell. I'd be much more worried about poison gas attacks and coordinated massively distributed firebomb attacks. These are the kind of low-tech high-casualty attacks at thier disposal right now.

      Up until 3 hours ago, we [swin.edu.au] said we were the only machine in the top500 dedicated solely to astrophysics. Now we are one of 2 :)

      But we use 180 processors, @ 2.15 GHz, and get about 0.90 Gflops/processor, whereas they get about 0.88 gflops/proc, getting us in the top 180th.

      The difference being they have faster memory, and we have a big badass switch. They have two switches, with something like only 10 gigabit between the switches! We have 250gbit within our one switch. a third of our nodes have 2 gigs RAM, and we also have room for upgrade to more nodes on our switch, and they don't. So, in the words of Nelson "Hee haw!" :)

      When they say $1000 per proc, they are not factoriing in their two switches. This will bring the price up to about $500,000, unless someone is donating a switch or 2 :)

      We have about the same cost ratio - something like 250,000 .au dollars for all our procs (and maybe switch - I don't know the details) - half the performance, half the cost.

    • Back in the days when I was working with LAVCs (Local Area VAX Clusters) over 10-Mbit Lans, diskless systems were possible but any disk I/O hit the bandwidth of the entire network. Pageing could murder the system. Also for larger clusters, simply loading the system on a number of machines took time as a mass storage server can only serve one system per request.

      Ok, modern LANs, especially this one is a lot faster, but you still don't want to burden your cluster communications bus with disk I/O requests.

      Anyway, that 80 gig Maxtor does not add much to the cost of the node.

      • Anyway, that 80 gig Maxtor does not add much to the cost of the node.

        It's not the price of a hard disk in a cluster node that causes the trouble, it's the fact that you now have one more power-drawing, heat-generating, moving part - that's more likely to fail than anything else in the system!

      Sounds like they have 10 ports @ 1Gbit each free, so get about 10Gbit between the switches. When we [slashdot.org] (position 180 on the latest top500) were investigating thin-tree connections, we thought that we might be able to effectively run one job on a third of the nodes, another on the second third, and miscellaneous jobs on the 3rd (since we have two or 3 researchers who like to use lots of resources, and people like me who only need a single proc at a time). So you just partition the nodes and only allow your mpi jobs to sit on one group at a time.

      Then there are things like openmosix which deal with topology automatically somehow. They will try to calculate the speed of the interconnect and the various nodes' procs (if heterogenous), and work out the distribution in the most efficient way. I am going to try to convince my sysadmin to try out openmosix on the lesser-used nodes of the cluster, because there is a feature of it that I think one of us might like - the combination of memory of the different nodes in one big contigous space, but right now we are busy cleaning up after the upgrade.

    The free software and low cost supercomputer are not so much news anymore since every intelligent consumer of compute cycles has at least one of these clusters available. No one has to "imagine" them anymore; they are real and commonplace.

    What's a nice development here is that the Los Alamos team has not only brought down the ratio of

    $/FLOP
    but they've started looking to bring down the ratio of
    Watt/FLOP
    as well.

    It represents an uncharastically appropriate use of resources at the Department of Energy and it also helps point the way for businesses looking to further minimize operational costs of racks of computers in air-conditioned rooms.
