  1. molecular dynamics on GPU on Same Programs + Different Computers = Different Weather Forecasts · · Score: 0

    In molecular dynamics simulations, kinetics are known to be approximate and states at a given time are not considered directly correlated with that time point; we only hope to get statistically correct distribution of states across ensembles. Consequently, differences in rounding between wildly different compiler/hardware architectures are expected. However, deterministic behavior of the system is achieved by employing higher precisions for accumulation steps, which ensures that averages over a sufficiently long time (big enough sample) are the same no matter what hardware is employed. Consequently a tremendous speed-up is possible running CUDA code on consumer grade nvidia cards which have far fewer double precision execution units than single float precision units. So, we have deterministic trajectories but nobody expects these to match real-world processes on a time-function basis :-)

  2. Re:Wow on NVIDIA To License Its GPU Tech · · Score: 1

    I may be mistaken, but I anticipate that licensing the hardware will require sharing the associated driver sources with licensees. That seems like a step in the right direction, albeit for more profitable reasons.

    The state of the art on GPUs is the latter.

    We'll have +100 exaFLOP systems in five years, 100 times the performance. Major structures in cells, and complete viruses, will be modelled to the atomic level

    Waiting for faster interconnects!

    This isn't exactly representative but isn't too far off, either. The cost of living is commesurately high in comparison to the economy's strength. Unless you're in business, or working directly in the construction or oil industries, you're probably relatively poor.

  7. Re:Hundreds of million$ already on just glucose on $10M Tricorder X PRIZE Kicks off · · Score: 1

    The best solution would be a portable low-power high-field NMR (OK, I might as well ask for a flying unicorn). You can detect characteristic resonances for a gazillion compounds and through TOCSY isolate them from other signals. IMO 50% of diagnostic medicine or more could be done with NMR.

    The funny thing is, Planetes wasn't really about collecting space junk.

  9. Fair enough on China Calls For Even Firmer Internet Control · · Score: 0

    It's not like the US government isn't trying to subvert foreign governments worldwide. It's a reasonable concern. On the other hand, banning things like twitter isn't going to fix the problem.

    The internet is a fad. All too soon it will be vastly different from what it was for the last 20 years.

    Thanks to redundant backups, the average downtime of a cloud-top computer is likely much lower than that of a desk-top computer.

    Unfortunately science isn't free and funding is not proportional to the number of scientists.

  13. Re:Mutations on Central Dogma of Genetics May Not Be So Central · · Score: 1

    Oh, that may be believed, but its prevalence as a theory is due to the somewhat poor level of retrospect we currently have. I don't think anyone who's given it much though will believe it, anyhow. It's just that we don't have a simpler autocatalytic molecule to point to. While it's very likely that life passed through an RNA world stage; to imply it's the consensus on the origin of life is naive.

  15. Re:"ELEETO"? on Google Patches 10 Chrome Bugs, Pays Out $10K · · Score: 1

    It's probably an incremental title - the first (most) elite is elite 0, the penultimate h4x0r is elite 1, and so on... It's a privilege to be the best - a single digit is easier to type than a half dozen are, and 0 falls on the underused right-hand side of the qwertyboard.

    Wasting your own resources is not better. Just have it slow down the rate of password attempts exponentially as the number of attemps increments.

    You are also wasting your own CPU cycles. Just make it constant and lock them out after a set period of time.

  19. Re:The obvious solution on China Says US Uses Facebook To Spread Political Unrest · · Score: 1

    Ideally Facebook would give you a reasonable blend of information about the people you care about, with minimal information about or from people you don't really like. However, suppose there were heuristically-identified vectors for promotional material. Not salespeople - just the subset of the population which has sincerely latched onto some given idea. These users could be located among the whole user base by filtering user communications and user networks (social graphs...). Amplify the signal of these identified people in the information feeds of their peers, and you will have used people's identities for advertising by suppressing the stream of ideas and information promulgated by your adversary. Paying to advertise your ideas is equivalent to paying for censorship against your adversaries. Marketing is fraud.

  25. Re:Alternatives? on Inside the Fake PC Recycling Market · · Score: 1

    People have to accept that the cost of providing or obtaining an object may be much lower than the cost of owning that same object - but these costs cannot be escaped in an integral democratically-governed nation. It's a simple fact but it doesn't seem to exist in some peoples' (micro)realities. People have long hocked this scarcely-tangible commodity ( transfer of responsibility for disposal ). However, the scam is hardly as shocking as the high level of support it enjoys. Most people will still prefer to pay less for the scam service (which has caused endemic heavy metal poisoning among adults and children in many villages), rather than pay more for proper disposal.
