  1. Re:40Gflops on Audio Processing on Your Graphics Card? · · Score: 1
    They aren't making the GPU more complex, nor adding capabilities. They are leveraging the fact that the GPU is capable of running these simple transforms *without modification of the processor*. RTFA, nowhere do they indicate that this is anything than a stock Nvidia GPU...

    So where is the problem? The GPU is not being modified or made more complex or getting any added capabilities. Truth be told, you could simplify and strip some capabilities from a GPU and still have a decent DSP.

    Think for a second, any modern video card is capable of displaying 16M discrete colors, right? The equivalent in the sound world are notes, of which in the chromatic scale there are 12. Even running octaves through the entire human audio spectrum still prduces less than 16 million notes. We can even add all those tiny little frequency shifts that individual instruments may have and still be under 16 million notes.

    I could see your concern if doing this involved fundamental changes to the GPU, but that is precluded by this method. What the developers have done is found the one piece of silicon in your PC which is closest to being a DSP. In point of fact it is more capable and powerful than a built for purpose DSP. The game designer doesn't give a rat's ass what you do with your GPU when he isn't using it, so why not use it, especially since it does not require modification or addition of any additional silicon.

    If you want to knock it, try and hit something relevant. For example, the GPU is not a DSP, that seems to indicate that there is some software magic which is interpreting what the GPU spits out. If you ask me, this is where the flaw is likely to be, not in some non-existent complexity or extra capability...

    And this is a problem how?

    No really, I'm interested to hear why this is a problem. Ever heard of any assembly line? Yeah, that's the thing where a group of simple workers outperforms a group of complex workers. Cars can be built by braking down the task into a number of simple tasks that can be completed without leveraging expensive resources. Similar to the GPU and CPU, the GPU is capable of performing a rather significantly larger number of simple operations compared to the CPU. Similar again to audio editing, which is nothing more than the application of a series of simple transforms.

    There are tasks in audio eiditing more suited to the CPU than the GPU, but from what I read, you would be using the GPU for tasks suited to the GPU, and the CPU for tasks suited to it...

    Finally, and anecdotally, I've ripped apart more than my fair share of electronic recording equipment, signal processing gear, etc. etc. etc. I've never found an Intel Inside sticker on one, nor anything that would be better than marginal as a general purpose CPU. Usually a bunch of ASICs, specifically DSPs. Your GPU is an ASIC too. These two ASICs have more in common with each other than either does with your AMD/Intel/VIA/Transmeta/what-have-you. The biggest difference is the GPU is evidently less differentiated and capable of a wider set of tasks than you would expect.

    Your reaction seems to be one of "cool for it's own sake, but so what?" but this really is a case of using the right PU for the job...

    I had a Prof in U who used to make similar statements. On one occasion a student took umbrage with this position and demanded data and proof. The prof indicated he would be happy to do so, as soon as the student was able to give him two problems, one 25% more complex than the other. After 15 minutes of demolishing every example offered by the student, the prof went on to explain that until the student was able to evaluate complexity in a meaningful and coherent fashion, any such proof would be a waste of time. The student was citing examples, which as the prof demonstrated, were consistent with scaling not complexity. A 25% increase in scale, while easy to understand and quantify, is not (in most cases) a significant increase in complexity, and certainly not a 25% increase.

    More often I think folk don't understand what a 25% increase in complexity really is. Once you have a valid framework to make this evaluation it is easier to see how this relationship works, well, after you evolve some way of evaluating solution complexity as well...

  8. Re:From memory on Does Shareware X-Chat for Windows Violate the GPL? · · Score: 5, Insightful
    Dangerous ground there my friend.

    If a principle is only a principle when "big business does it" then what is the point of the original principle?

    More to the point, the drafters of the GPL utterly rejected that proposition, violation of the GPL is violation of the GPL, regardless of how many employees you do or don't have.

    Lastly pally, you seem to think that everyone should just pipe down and be happy they are getting something for nothing. They aren't, this free software doesn't spontaneously code itself, real people do that. When real people contribute their time and effort with no financial compensation and little formal recognition, perhaps their motives are worth examining. When you begin this examination, you start to realize that only certain projects seem to collect these voluntary laborers, and the vast majority of these are GPL. The sophisticated observer at this point will stop, ignore the fact that the software is free, and maybe begin to wonder why this is, and how come there is so much of it. I'll submit to you that maybe, just maybe, it is BECAUSE of the GPL that all that free software is available.

    So perhaps we should look a little deeper before making crass observations about just being happy things are free, and maybe look at some of the why's and wherefore's and maybe developing a more sophisticated view of F/OSS than "something for nothing" (Which it most certainly is not, ask some-one who writes code...)

    As for X-chat, every individual who has contributed code needs to step up and demand the code be removed. The rest of us should remove the program, cease any participation in the development thereof, and make clear to the developer that we cannot accept his interpretation of the GPL, and that no OSS project can survive in an environment of apathy, which his current actions are virtually guaranteed to create.

    In summation, lock both the developer and the original poster in a small closet with RMS.

    First, you aren't going to put 15-20 Xeons in place of a single Alpha, if only because the majority of your x86 budget is going to be chewed up by redundant costs. Consider: I can stick that Alpha in a small server closet, with a smaller environmental control system, a smaller UPS/backup generator, and a smaller fire supression system. Best of all, only one system to worry about backups and administration for.

    Now, I simply am not going to be able to beat that with 15-20 Xeon boxes, even nice flat 1U rackmounts are going to have higher requirements in all those critical categories. Never mind system/cluster administration, SAN crap, etc. etc.

    The point is there are other criteria than simply cost and processing power. If I made all my decisions based on price vs performance without taking into consideration reliability, ease of administration, etc. etc. etc., well let's just say my employer wouldn't be worried about my /. time, since I wouldn't be employed here.

    Ultimately diversity is a good thing. In fact diversity is the underlying reason for the success of the x86 architecture. The thesis that there is no need for any other architecture, simply rack up the x86s, is irresponsible, short-sighted, and in fact flies in the face of reasonable analysis. Maybe taking pot shots at x86 chips is bullshit, but denying the value of other architectures, approaches and ideas is so much more bullshit.

    Okay, so some people have had their sense of ha-ha programmatically removed...

    But, since I have been attacked, I will defend. Allthough meant to be humorous, you will note I clearly delimited that the TCO studies in question were Microsoft-funded, not Pro-Microsoft. Is it possible to have a TCO study that is Pro-Microsoft and not Microsoft-funded? Of course! As you point out, you use the right tool for the job, and in some cases that may mean Microsoft.

    As for your first question, do you not understand the quote? The choice is between one of three types of lies, not just the first two. To answer your question a pro-linux tco study (if a lie) would be #2, a damned lie, since it was not funded by Microsoft, and my personal viewpoint makes it a damned lie, as opposed to the ordinary version...

    However, the only lie in all three posts so far is your assertion that TCO in general is a lie. Your trivial and irrelevant example bears this out. You could save money on gas by switching to a bike, would you save money overall, probably not, since the time required is prohibitive (and money is nothing more than a unit of time, as in my employer is going to be pissed about the 15bucks worth of time I'm wasting teaching you how to prosecute an argument...) TCO done wrong, (like the Microsoft funded TCO studies cited originally) are worse than useless. Any study which reaches a predetermined result, particularly one in keeping with the interests of the funding body..., need be considered suspect. Over-applying the results of a TCO study, for example to other businesses or sectors of the economy where the study was not taken (incidentally another feature of the Microsoft funded TCO studies...) is equally useless in the best case scenarios, and smacks of fraud in the worst case scenarios.

    Ultimately, most people don't know how to evaluate the information being presented to them in a TCO study, nor are able to apply those results meaningfully to their own situation. These folk tend to question the value of the entire process, rather than questioning the process (something liable to yield results!) This bias tends to create situations where they discount an idea because of the method of presentation, comitting the egregious sin of omission, much like they would like to accuse the presentation method of doing...

    To return to your facile example of the car/bike analysis, apart from lousy phrasing, there certainly could be conditions where riding the bike the 20 miles would be an overall time/money savings. I don't know if you are a 350 pound couch potato that could desperately use some activity to improve your health (and incidentally extend the amount of time you have on this Earth, which unless I'm mistaken would be a profit...) or if you are a health nut who spends $100/month to go to the gym and ride a stationary bike every day, in which case not paying for the privelege also saves those fees.

    I suspect that if you think about it for five minutes that your problem is not with TCO studies, but poorly done TCO studies, much like my issue with poor analogies.

    In such an environment children are a resource, not an expense. Birth control is only attractive to a culture where children are an expense, not a resource. Until you materially bring up the overall level of prosperity in these cultures you cannot escape that simple economic reality.
