  1. Re:Good luck on the compiler on Intel Squeezes 1.8 TFlops Out of One Processor · · Score: 1

    Yeah, so I screwed up a bit: Intel's new chip, which has a somewhat similar architecture (bunch of less capable units working in parallel), does not actually run off a VLIW. However, my core points still hold: (1) there is a class of applications which will run well on this sort of processor, but the majority won't, (2) effective use of the processor will either need re-coding of applications in a parallel-conscious language or a very smart compiler, and (3) for many applications, a cluster of general-purpose machines will be more cost-efficient.

    Incidently, the sarcasm is not appreciated. I have a full degree followed by 13 years designing parallel and distributed systems. I admit that I confused Intel's research with stuff going on at IBM.

    In response to the sibling comment, the cost is in the design and manufacture of a new chip. The fixed cost to create a new processor is enormous, which means that have to produce millions in order to drive the per-unit price down. If I have an application that runs about as well on an 80-core processor at $500,000 as it does on 80 $1000 machines, guess what I'm going to choose? Heck, even if it takes 200 such machines, I'm still better off. (Excluding power considerations.) People have been building massively parallel machines for years, but they have never achieved broad commercial success.

  2. Good luck on the compiler on Intel Squeezes 1.8 TFlops Out of One Processor · · Score: 1

    As the article points out, this is a VLIW (Very Long Instruction Word) design -- in effect, each instruction word will be broken up into chunks, with a chunk going to each processor. This means that you can end up with some bizarre situations -- what happens, for example, if one processor needs to jump to one location in memory and the other 79 don't? Effectively, your compiler would need to be able to realize this, and have the instructions at that memory location for the 79 processors be the same. (In reality, I don't think you'd do this -- that processor would probably just sit and wait for the others.) This is not the equivalent of having two cores, with each able to run independently.

    The real bottleneck here is the compiler, not the processor, because the compiler has to be able to pick up on implicit parallelism in the code and dole it out among the available cores. While it's possible to the compiler by using a language where the programmer specifies the parallelism, if you think about it, that's the opposite direction from the progress of computer languages in the last 20 years.

    The biggest problem that this technology has is that it is expensive when compared with a compute cluster, which can scale easily and can be more easily programmed. The main time the cluster won't do better are the instances where each core needs results from other cores so frequently that the overhead in message passing is too high.

  6. Re:Scanning "not creative" enough? on Viacom Claims Copyright On Irrlicht Video · · Score: 1

    It depends. If it's a purely automatic process, then format-shifting does not create a new copyright. Copyright requires some creative expression beyond the pre-existing matter. So, for example, copying a recording of a congressional hearing onto cassette tape doesn't add anything new and thus there is no copyright. But, if you take that tape and do a bunch of audio engineering work to make it sound better, the result would probably be protected. Note that doing this produces something of a thin copyright -- a transcription of the tape would be in the public domain, because the transcriber didn't copy any creative expression.

    This was essentially the argument with photographs -- originally, there was an argument that a photograph was just a copy of something in nature. And, since you can't copyright nature, you shouldn't be able to copyright the copy. But, courts have found that photographers put a lot of creativity into doing things such as framing the shot. I don't know for sure, but I suspect this means that the output of, say, a surveillance camera is not under copyright, unless the action in front of it were performed.

    Aha! You can claim it, under the current Copyright Act. However, this guy claims that he invented the electric slide in 1976. But, the current version of copyright law that we have didn't become effective until 1978. His claim of copyright would have come under the 1909 act, which contains no such reference. There are other problems related to the 1909 act as well. If I recall correctly, publication was necessary for protection.

    Even under the 1976 act, it has problems. For example, the fixation requirement at the end of that quote may be at issue here -- if he created the dance AND fixed it sometime before others copied it, then it's probably protected. But, if he created the dance, others copied it and THEN he fixed it, well that's another matter. Fixation of a dance can happen in any of a number of ways, but usually happens either (1) in a notation used by professional choreographers for such things or (2) just by videotaping it.

    And, finally, up until the late 1980's, there was a notice requirement of copyright (Remember the Circle-C?). No notice, no copyright (with some limits.)

    Second, yes, I do believe the situation is better. It sounds like your scenario is not well-run -- any university that continually pulls their phd candidates' research out from under them is not likely to continue to have many such candidates. Bayh-Dole does not require your university to do what its doing.

If no company could get exclusivity to your work, no company would want to spend the effort doing the development. And, as a result, both you and your research languish in the university.

    Here's another way to think about it: the federal government pays for a bunch of research. Once the research is done, what SHOULD happen to it? Companies will very rarely develop technology which they do not have the exclusive right to -- the risk is that they do the development and then somebody else comes along and steals all their work. And, the federal government proved itself to be horrible at commercialization in the 60's and 70's.

    Hardly. Private companies do research all the time. Even if they didn't, your solution (denying patent protection to the results of federally-funded research) wouldn't help the situation: no private company would invest in research because if somebody in a university discovers it first, the technology falls into the public domain. The reason why we allow private entities to commercialize the results of federally-funded research is because the previous situation was so bad -- useful research was just sitting in labs because nobody could make any money off it.

There is already a thriving market in such research, thanks in large part to the Bayh-Dole act, which allows universities to exploit inventions funded by the US government. The gov't gets a non-exclusive right to practice the invention (or have it practiced for the government) and there are a few other relatively minor restrictions. Because of this, Universities have been mining their research for years. Especially in the biochem and biotech industries, the vegas-like attitude does not exist. Quite the opposite -- researchers typically now conduct their research with an eye toward its commercial practicability. Before Bayh-Dole, this rarely happened.

    First of all, the Constitution does restrict something -- the ability of the government to suspend the writ of habeas corpus. But, the fact that some rights are not enumerated in the Constitution does not mean that those rights do not exist.

Effectively, this means that our rights come from God; they are rights which we possess everywhere and anywhere, no matter what the laws of the place are. Under this view, while it is technically possible for a government to use force to limit the exercise such rights, any such limit is illegitimate.

    I will agree that whether people have the right to petition for the writ is very important. My point is that what you call "Gonzalez' analysis" was not a statement on whether people have such a right, but a recognition that if they do, that right is not specifically granted by the Constitution. It does not speak to the existence of the right, only to its source.
