  1. Re:Same latency with 4 processors on A Three-Way AMD Opteron Server · · Score: 1

    You can have 4 processors in a tetrahedron configuration and still have any processor one hop away

    Ignoring the physical trace-routing issues, you can have N fully connected nodes as long as every one has a N-1 connections (ie, a dedicated link to every other node), plus you need at least one bus-drop somewhere.

    In practice, all those connections need to physically connect somewhere, making more than a handful of fully-connected processors all but impossible.

    Problem 1)
    Draw four circles on a piece of paper.
    Now draw a line from every circle to every other circle without crossing any lines.

    Problem 2)
    Draw four circles on a piece of paper. Draw two "pins" on each.
    Now draw a minimal path between any two circles such that you can only start and stop at a pin, and only one connection can go to a single pin.



    You have the right idea for problem 1, that for low-N, you can just route connections through different layers of the board. But that only works for low-N and doesn't generalize (though in fairness, neither does to the "3-CPU" solution).

    For problem #2, no real solution exists other than limiting the degree of connectedness to some low number of pins (2 gives the simplest case above single-CPU, a daisy-chain or ring topology), or having centralized signal switching (star topology).

    I have personally used it (the CPU, not that exact MB) as both a Linux fileserver and as an XP machine. For Linux, it works like a dream... Low heat, low power requirements, more than enough horsepower. For XP, it feels a little sluggish if you bog it down with a large number of tasks, but for web-surfing while listening to music, or even watching a DVD (almost almost all of VIA's MBs have hardware MPEG2 decoding, the newer ones support harware MPEG4 as well), it just does its thing without a problem.

    Have you bought a blender recently? A plain, ordinary blender, not any sort of specialty food-processing setup.

    I have. Repeatedly. Let me describe my experiences...

    You can get three classes of (home-use) blender... The uber-cheap $29.95 WallyWorld special by the likes of Hamilton Beach or Proctor Silex; the $60-$120 range blenders, typified Waring and KitchenAid (though they certainly make their share of low-end crap as well); and the elite makes such as the $400-$600 BlendTec Total Blender (as seen in "Will It Blend" - Short answer, "yes, it will", and no, I have no connection to them).

    The $29.99 blenders will usually work once. Sometimes they work a second time. I had one last a full three months, once.

    The $400 blender I can't say much about. I would expect them to work, and many of them have a lifetime warranty, but I won't pay $400 for a stupid ice-chopper. I'll do it manually with a bag and a hammer before I pay that much.

    Now, the $60-$120 blenders... Therein lies the sweet-spot. They may not blend marbles and broomsticks and ipods as with the BlendTec, but They turn ice into mudslides juuuuuust fine. And my current blender has lived for over two years. It does seem to start a bit more sluggishly these days, so I suspect it will eventually die from the lubricant dissipating or breaking down. But I'd say it has another year or two left in it.



    So, my point?
