theSkyNet Wants Your Spare CPU Cycles

An anonymous reader writes "Thousands of PC users are being called on to donate their spare CPU cycles to help create a massive grid computing engine to process terabytes of radio astronomy data as part of theSkyNet project. It will be used for, among other things, processing the huge amount of data expected to flow off Australia's forthcoming Square Kilometre Array telescope." One can only assume that "other things" will include achieving sentience and finding John Connor.

      This isn't exactly new. Sure modern CPUs have clock switching, but systems since the 80486 (possibly earlier) have halt instructions that allow the processor to stop doing work and save power until the next interrupt.

      OTOH, I know several people who run distributed computing software on their computers during winter, specifically because it produces heat, which otherwise would have to be provided by a fan heater (because they don't have AC), so it's not necessarily wasting energy, but it will cause your computer to use more energy, so it's not free (unless it's someone elses computer, heh).

      The advantage with cpu donation, is while the energy isn't free, the computing capital is, since the computer will depreciate just as fast whether it is running jobs or sitting idle. By donating your idle cpu time (at the expense of higher power bills) you can contribute more to a science project than if you were to simply donate the same amount of money you spent on power to the project, because they don't have to buy the additional hardware.

      To sum up, if they spent the money, they would have to buy computers and power to run the computers, and AC to cool the computers, but when you donate cpu cycles, you only have to pay for the power to run the computer, since you've already bought the computer for other purposes and a single desktop or notebook computer can generally be cooled adequately with passive convection.

    Yeah, people keep bitching about that first weekend where a software glitch caused the same work to be sent for the first weekend we were in operation. As someone close to the SETI@home team, please stop bitching about a bug that's been fixed for 11 goddamn years!

    BTW, we'd love to make use of the SKA, but it doesn't exists yet.

    Yeah, SETI@home found 114 sources of pulsed emission, possibly a new form of pulsar. But you don't wanna hear about that. You want to hear about the what the telescope that doesn't exist yet might find.

    How is Java at producing code SIMD code, or code that runs on GPUs? Java can outperform poorly written C code, which does form the bulk of scientific code bases. Outperforming well optimized processor specific code? Not really.

    Go investigate the relative performance yourself.

    http://shootout.alioth.debian.org/

    You are wrong. These comparisons are apples to apples, not “proper” versus “improper” code. I found that link from The Java is Faster than C++ and C++ Sucks Unbiased Benchmark, which satirically demonstrates how people may arrive at flawed perceptions about performance.

    Generally speaking, experience teaches engineers that languages are not slow. Algorithms and execution environments are slow. Bad code with good compilers can be fast. Good code with bad compilers can be slow. However, languages do affect developer performance.

    In the simplest sense, your belief that any language is slow relative to another is easily refuted. Consider two programs written in language X and Y respectively. Both programs produce identical output for identical input. Suppose we then introduce machine translation that compiles X into Y (or vice versa) before compilation. Or, alternatively, our respective compilers for X and Y produce identical output.

    See what I did there?

    Nobody was bitching, so chill, bro! I was not aware, that this was merely a bug. My impression from back then (it's been a while) was, that there was simply not enough data from Arecibo available due to other work being done with the radioscope (is that the correct term?). If that is not an issue anymore, then great!

    I'm completely with you on that. But it's simply gonna take a while. It's simply unlikely, that the first contact will be "Contact"-style ("Jackpot!"), where we get all kinds of wonderful things sent to us right away. Chances are, we detect something at some point, and then it will take a few decades of back and forth communication, if we even have a language we can agree on and understand each other. It might even turn out, that we are the advanced guys. In that case what are we gonna do? Send 'em a ZIP'ed copy of Wikipedia? :-)

    That's wonderful. But you're not conserving energy, the same way a car just idling in the drive-way, as opposed to actually being driven (the whole point of a car), is not exactly doing any favors for conservation/the environment.

    Especially not, when that computer you're letting sleep most of the time, will be thrown in the garbage 5 years hence because, although fully functional, can't do the things you want anymore. So, to use the car analogy again, is there really something reasonable about a car being scrapped, that has only been driven for 4500 miles all in all? Me, I don't think so. It failed its designed-for purpose. Or rather the user failed to use it for its purpose.

    But it's all good. You can, of course, do whatever you want with your machine(s). Even use them as nifty paperweights. :-)
    But me, even my old 486 is still chugging away on distributed projects. Why? Because it still works and it will do *something*, as long as it does.
