    I haven't used an Altix, but from the docs it seems sgi's patches provide a lot of the tools and goodies from IRIX. On a montster Origin, "top" gives 4 nicely formatted status lines above the process details. For specific details on each processor and other aspects of the machine, there's "osview". There's also a handy script called "hinv" that prints out a hardware inventory of the machine. "hinv -m" even prints out the part numbers and laser-burnt serial numbers for the various boards in a system.
    I believe the Altix software environment provides all three of these utlities. Each of which gives pages and pages and pages of nicely formatted, human-readable details with the right flags.

  68. A Reasoned Approach by Anonymous Coward · · Score: 0

    I'm all for cleaner rivers, air etc, but you must understand that all policies and laws have a price. To understand if that price must be paid, we have to ask ourselves whether any particular observation is proof that our theory is correct. This must be based in science and not speculation.

    Why?

    Because the alternative is the same sort of specious 'reasoning' you just used. Unless it is tempered with logic and checked with reality you could just as easily use similar 'reasoning' to conclude:

    1. (Premise) If you don't believe in God you will go to Hell.
    2. You might as well believe in God because:
    a. If you do believe in him and he doesn't exist at least you won't go to hell.
    b. If you do believe in him and he does exist you might go to heaven.
    c. If you don't believe in him and he does exist you will go to hell.

    Using this argument most muddle-headed fools will just panic and start believing in god out of fear. Fear causes decognition which makes it impossible to rationally evaluate the likelihood of the premise, the possible outcomes or the validity of the conclusions. Never mind that the premise has not even a shred of proof.

    It's classic propaganda and mind-control. I'm sad to say that most educated fools fall for it also.

    Given this, it's also obvious that the propaganda being spread by many environmentalists in government is religious in nature. The very definition of a religious belief system is that its concepts are not falsifiable. Not matter what you tell the true believers, it is simply proof that their belief is true.

    Steps:

    1. Keep repeating to the general, uneducated populace that global warming is everwhere.
    2. Weather, by its very nature is chaotic. Yes that means you have local minima and maxima. Sometimes these locals change.
    3. If we are having a bad heat wave in Paris where grandparents are dying while mummy and daddy are vacationing in the Riviera, tell the people its because of global warming.
    4. If we are having a 'freak' cold spell in the winter, tell people that global warming causes that too.

    No matter what, use it as proof of global warming. Of course this line of reasoning is ridiculous, because the only proof that global warming doesn't exist is if we have several decades where today's temperature is never outside the first standard deviatiation.

    -- so ---

    Global warming might be real. Cold fusion might be real, but we don't arrive at intelligent conclusions by looking at chaotic patterns and 'cotton picking' the choice data samples we want for proof. This is the oldest mistake in the experimental play book. Don't fall prey to it.

    Please don't misinterpret what I'm saying. I'm not some sort of conservative nut case. I'm green in all the ways you might imagine me to be green. I don't waste energy. I'm all for advanced and cleaner forms of power. Wind. Solar. Newer forms of fission (pebble beds) as a mid term replaccement to coal. Transition to hydrogen or He3 or something similar when it becomes mostly justifiable.

    Good luck and use the brains that you were born with.

      4. Political dissent was brutally repressed (usually by raping, then torturing, then murdering entire families right in front of each other),
      5. Terrorists were harbored and their families paid off when they died in a suicide bombing.

      For liberals like you these facts never enter into your reasoning because blind hatred of President Bush trumps all. This is the same conflict we had during the Cold War, liberals afraid to be agressive or outright sympathetic to the enemy, versus conservatives who actually fight to win.

      We cannot win the War on Wahhabism on the defensive, going after funding and arresting the occasional terrorist. These things are symptoms. The disease is corrupt dictators and the thug culture they promote or are unwilling to control; free people don't tolerate these kind of leaders much less indoctrination of their children by murderous animals. Treat the symptoms, sure, but the primary preoccupation has to be curing the disease. In your presentation you ask 'for what?' The answer is to break the cycle of break the cycle of murder, opression, indoctrination, and terrorism by taking power away from the Wahhabists and giving it back to the silent majority. But we will be successful in spite of the constant pessimism and shortsightedness!

  71. Intel's compilers are "OK", long story by Anonymous Coward · · Score: 0

    Itanium compilers are the result of a long, crazy story. At one point, SGI was working on their own opensource "Pro64" compilers, but stopped when talk of highly optimized gcc/itanium came about. But... gcc on itanium suffered from major suckage, sgi had already canned their own compilers, and had to resort to Intel's fast-but-buggy compilers.

    For those who aren't keeping score at home, this is typical for sgi. They start working on their own mega-cool project then can it when they smell the vapor of some other company's product they could just implement instead. After awhile the winds blow the vapors away, sgi realizes the emperor has no clothes, and their whole product line takes a hit. This happened a couple time in the past... once when they stopped developing the MIPS R1x000 processors and stopped design of Beast and Alien processors when they heard of NT and Merced/Itanium. 18 months later and the damn chip still hadn't shipped, SGI's x86 PCs weren't selling, and their MIPS/IRIX customers were demanding something faster than R12K/400 in the workstations and big iron. SGI started CPU design again, but have yet to release anything more than speed boosts, process changes, and minor silicon tweaks. The same happened with graphics. They canceled the Bali (InfiniteReality replacement) project in favor of PC-based graphics clusters. When that didn't work, they had to tweak IR for two more revisions. It wasn't until this summer that they FINALLY got their massively parallel ATI FireGL system to market.

    SGI has done some cool things that have helped spark neat developments in the computing world, but they could have done even more had they stuck with many of their projects in the past.

    Altix rocks and Itanium2 is better than most folks are let to believe, but the gcc compilers aren't very optimized and the Intel compilers are a mixed bag of fast/slow performance and obscure bugs. SGI's Itanium compilers were never finished and never saw the light of day. SGI followed the vapor once again.

    Still, for the money, I'd take an Altix over anything short of a Cray X1. Altix is one hell of a machine.
