  1. Re:We make jokes about Quake on MandrakeClustering Shows Off At ISC2003 · · Score: 5, Informative

    Where I work (www.ornl.gov) we run weather models, nuclear stuff (explosions, fallout tracking, power plants, nuclear medical materials simulations), genome projects, particle flow analisys, a bunch of stuff (though unfortunatly for Mr. Dyslexic here no speel checker for slashdot :) ). Oil companies process seismic data to try and map what's underground, medical companies help develope medicines and gene therapy.

    Some of the projects (human genome most currently) may run for weeks over 10-20 terabytes of data. The algorithms used are pretty mundane - you just need to do them A LOT. Some of the particle flow stuff may model individual molecules in a furnace for example (not rendering the frames, but modelling the interactions and how to create a more effecient jet engine).

  2. Re:Benchmarking on Apple Hardware VP Defends Benchmarks · · Score: 1

    Yes, it does matter. I want best case (optimised for processor), worst case (no optimisation), and "average" case (normal apps).

    If processors A's best case is 1500 (units - I don't care what they mean), worst case is 1450 and average is 1475 that may be a better choice than worst case 500, best 2000, and and average 1500 if you can not get optimised code for that specific processor and are going to run lots of differently optimised code over a long run.

    Especially when running on an architecture that they code may be written in such a way that processor optimisation is hard worse case can be VERY valid, though less so for normal desktop users.

  3. Benchmarking on Apple Hardware VP Defends Benchmarks · · Score: 4, Insightful

    The Apple guy is both correct and wrong.

    Correct in the sense that he wasn't necessarily being unfair. I don't think Apple was raelly cooking the books here. OTOH benchamarking is quite difficult.

    No, it would not be fair to compare intel compilers to gcc compilers. But what about, say, another non-hardware tied compiler? Look at it this way - 3dmark scores on graphics cards. Theoretically it should give a good impression on thier relative hardware - but we all know that it doesn't necessarily. It may do something bad on one system, great on another, one system may cheat and have special code to work better with that particular test.

    Same here. Ideally you would find many benchmarks, not just gcc, but both with all optimizations on, with all off, both with the best compilers, worst compilers, and middle of the road. You also need memory intensive, processor intensive, grpahics intensive, floating point, integer, and many others to get the full idea and compare it to what you need to do with the computer. For many of the crowd that worries over this stuff overclocking can become an issue also.

    This is why benchmarking is as much art as science. I care about all those numbers - I have code compiled specifically for my athlon-mp's, some generic, and some optimized for p4's for the consumer tasks. On our computation cluster we use specialised compilers. I care how it runs on all of it for real world use. But no hardware manufacturer does those extensive of a tests - they pick the best of the ones they can claim "fair" on usually.

    And lastly, in the end, who cares? Unless you are regularly running 4 hour jobs from a console it is irrelevent. It is more important that you are productive with the interface and that is personal choice. Few consumer tasks (and even programming tasks) require that power - and the stuff that does is generally handled by specialised hardware. Then if they have the fastests today they won't tomorrow.

    This is probably going to hurt my karma to dare say so, but one cannot help but notice the parralel with most religious beleif systems.

    Both yes and no. It depends on the conspiracy theory and religion you are comparing. Most religions do not consider lack of proof to mean anything. There are valid reasons to believe in a religion - but no proof.

    Some conspiracy theories have the same thing, just because they are conspiracy theories doesn't make them untrue (look at the original Illuminati several hundred years ago). But they look at coincidences and draw conclusions - usually they are not totally correct but can come close. That is "lack of hard proof" has nothing to do with it - just a series of stuff that doesn't add up and no contrary evidence to the theory. One can easily belive some of that.

    The strong form of the alien crowd not only says that no proof constitutes proof, but that evidence to the contrary is proof they exists as this is only a diversion. That is quite different from religion and a few of the conspiracu theories. It is completely blinding yourself to the evidence if it doesn't agree with you.

    The weak form (of which I subscribe) just says there is life out there - just because the universe seems large enough that it is difficult to think that we are the only existence. Nothing about it size, it frequency, or it's ability to travel. Like religion, there is no contrary evidence. Lack of proof has no bearing on this beliefe. Should you require undeniable proof before you believe then that is OK also.

    Not only that but the Vis market is also turning towards small clusters for rendering and driving the hardware. (to note, I don't work on the following project - I just get to hear them complain about stuff)The people here are purchasing 5 dual athlon systems with tons of ram per box and nvidia quadro cards. One central point and four rendering machines - I think (though I am not sure on this point) that the quadro's are off the rendering machines to drive the CAVE system. In any even the cluster is capable of driving the hardware

    This will spell the death knell for a large chunk of SGI. The contract costs on the origin machines is more per year than they are spending on the whole render farm - and you get no upgrades. They can, cheaper then just maintenance, upgrade thier machines once a year if they choose to. SGI will have to shrink based on this. They still provide some kick ass hardware in the actual CAVE system, but I don't really know if they can survive on it - though I think a company surely can - just not as large as they are now.

    I used to think the same thing. I've been working at a national lab for about three years now. I have seen at least two tinfoil hat stories about projects that the people I know are working on and have found them to be wild fancies. Does the govt do some shady tings? sure. But it's not that prevalent or extensive.

    It reminds me of seeing in one of the old building from the Manhattan Project a large red button with "magic" written on it in a halway with nothing else. We had all sorts of theories about what it did (the building does nuke power stuff, we occasionally had meetings in there). Turns out it was simply the building emergency power shunt.

    As for saic, they supply our Q clearence office workers (not the secretaries). These are the guys that print out checks, manage our administrative machines, networking contractors, and that sort of thing. A lot of thier involvement with secret stuff is in supplying that manpower. Of course they also have thier own research staff in other places (much like lockheed-martin or other defense contractors).

    The underground tunnels are empty. The Q clearence "secret" stuff is usually mundane. Usually if it really is something secret you are not going to know something about it (take the f117 or sr-71 projects for example). If you do, it is so remote and little that you are going to be wrong or just a very lucky guesser.

    That's a crappy job market. Ours just sucks compared to the dotcom bubble - which was insanely high. The jobs have basically came down (though a little lower) than what they should have been all along.

    I do agree with your second paragraph also. Give it time to adjust - at the small state school I went to there were about 10-12 CS, 20-30 IS, and over 100 IT. That is really out of proportion. Nearly all the IT (and a few of the IS) was because it was easier and made good money, once it is certain it will not make the fortune they wanted, they will move on.

    I work at a US national lab in High Permformance Computing - plenty of geeks. In the older crowd (30+ to 35+) not really that relevant. Most know nothing about it or think "cartoon == kids" 30- tends to like cartoons in general.

    The current group I am in I am the next to youngest (28) and am obsesed with it. The youngest has (24 I think) has never weighed in. The others (29, early 30's, 40's) think it is sorta wierd but have never really watched any (other than the wierd stuff I have explicitly showed them - though to be fair they don't watch much of anything, either tv or movies).

    As far as students go. The first year - one against (again in the 30's), three indiferent. They thought some stories good, some bad. Treated it as any other movie.

    Next year, one indifferent, one obsessed, one generally liked it.

    the last group I never polled about it.

    So, I would say it definatly has a large enough crowd to justify being on slashdot, that it is not just "Taco like Anime". Though it is not universal. It is almost a correlation of 1 of likes anime and likes video games. That, in and of it self, lends me to think it is valid.

    First off, microsoft employees tend to be quite happy so that is moot.

    Secondly there are several different types of monopolies, not all of which are bad. Take wal-mart - they have a near monopoly. They got there, and maintain it, by offering services very cheap for what you get. Large grocery stores ran out small busineses by offering the same food much cheaper. No one raelly complains about them (some do) because they use thier near monoply to offer cheap good and do not really abuse thier position. If a competitor is in the area wal-mart outsells them - not hire all thier help away, try to make it illegal for them to operate by draconian liscenses, and other such non-competitive practices. The good monoplies actually benefit consumers by providing sevices that could not easily be rendered otherwise while still allowing innovation.

    OTOH Microsoft employes all these and more. They do not maintain market dominance by provideing a superior product, they sue, hire away workers, try bad liscenses (take stacker and beos for instance) to maintain market dominance. In other words, thier monopoly is only perpetuated by thier monopoly, not through producing a product so wizbang or cheap no one else can compete. This is bad for the market as a whole. Though Microsoft is not as bad as some of the steel/oil monopolies during our industrial revolution.

    What will/does cisco do? well right now they still produce a very nice product, a larger corperation/money base allows them to be more experimental than a small company - they can afford the loss. It does impose standards - which is a good thing - but (I think) they are relativly open and dont follow the "embrace extend extenguish" approach. Of course they do not have the monoply that microsoft does either. Only time will tell.
