  • And that's different from most existing closed source software how?
  • Google sells search engine services to other companies to place on their web sites such as Redhat, Yahoo, Latino.com, the Washington Post, eToys, eGroups, WebVan, etc. These search engines include a good amount of customization and Google gets a monthly fee out of it of upwards of $2,000.
  • As much as opening source would be a Good Thing(TM), we look at Seti@Home and I just don't think this can be done in an open-source way.
  • i have tryed distributed.net , dcypher.net and seti@home. all of them have pretty interesting projects (distributed: math/crypto , dcypher: physics & seti@home: astronomy?) and i even intend to try popular power and parabon.
    here are my thoughts on all of these projects. i hope you will find them informative

    seti@home is really cool project BUT they already have enough ppl on the project so they are recycling units + they refuse to further optimise their clients because they have enough of computing power. clients exists for every possible platform in the world.

    dcypher.net has really interesting projects going on and is going to pay for processing power in the future. (they are already giving out some money on random basis. like 100$ to a random participant). problem with dcypher.net imo is that their software is still in the development phase. for example stats are not that good + you can cheat in gamma flux project by submitting same units twice or more (your computer generates gamma rays randomly so by just copying your buffers and submitting them once more you can get extra creds on the stat page). i believe that dcypher.net is going to be really good distributed computing effort in few months when they develop their software. clients exist for gnu/linux, freeBSD and windows. mac client is under development.

    parabon still doesnt have a gnu/linux client (they are developing it) so its out of question for most of us slashdot users even if they have really cool project (chemotherapy ). client seems to exist only for windows.

    popular power currently has a project on optimisation of influenza vaccination. they intend to pay for your computing cycles in the future. currently there are clients for gnu/linux and windows. mac client and solaris client are under development. linux client needs really lots of work , its really user unfriendly right now. it excepts you to install separate user just for running client. i will try it when it gets more user friendly.

    and at the end, my currently dist. computing project of choice. distributed.net. oldest dist. computing effort on net. you have several projects to choose from. its 100% non-commercial, you can get most of the source code for their clients, stats are great, clients are stable, they exist for "every os" in the world :). so right now i would recommand to go on with distributed.net (join team SLASHDOT :) but look into dcypher.net, popular power or parabon in few months.
  • I take it someone else pays your dorm fees?
  • It's a good idea you've got there, but the problem with good ideas is that someone else often wants to muck with them.

    With the way things have been going, I can imagine "shrink-wrap" licenses on your dishwasher, toaster, etc., saying that you haven't actually _bought_ the CPU inside, but are just leasing its use for its intended purpose. Moreover, The Company That Made It reserves (and requires) the right to run for-pay distributed services on "their" CPU your appliance in order to offset the cost of providing you with the appliance-in-question (or so the story will go).

    You heard it here first, folks...

  • i think you are missing the point here.
    you dont start distributed project to render one picture. distributed projects are suitable for tasks that need lots of computing power while they are not producing enourmous amounts of data. for example when you download an ogr stub from distributed.net your computer crunches on it for a week. size of one stubb is less than 1kb.
  • Hey, I got one of those Slashdot Cruisers, and let me tell you, they're chick-magnets!
  • If there is money involved, someone will compromise the integrity of the data being reported back, reporting that they have processed more data than they actually have. This has already happened with other distributed efforts that are not for profit. It's okay to have mistakes doing seti research, it's not okay to have mistakes in cancer research.
  • Why no company would ever touch it
    Quite the opposite, most companies invest a huge amount in computers that are idle a large amount of the time. Being able to recoup some of this cost is very attractive. It's like a school renting out a hall or gym outside of school hours.

    I just think it's a shame that it can only be done once. By that I mean, there's a huge amount of untapped CPU time out there, but once a system is in place to use it that's it, you can't use it twice. It's like compression -- one go and it doesn't recompress. Where compression "doubles" the storage capacity of a system, distributed computing "doubles" the efficiency of a computing system. From there on it's just tiny, incremental upgrades...

  • Should our goal for these programs be to leave them on all hours of the day so that we make, if we're lucky, .50 US an hour over electricity? No! We all walk away from our PC sometimes (during dinner, when nature calls, when a friend calls, whatever). For those times when we don't want to mess around with shutting the system down for some reason is why we should use these. You may make a little bit of cash, you may find the cure for canser or find an alien, and you get to brag about how much faster your box is compared to your neighbor/friend/chat buddie's with a realistic stat (except for me. I have a PII-233. Only 64MB ram. A HAHAHAH ATI RAGE PRO WITH 4MB RAM! HAHAHAHAHAHA!!!).

    Which brings me to my next point, what about the video card? During non-game use (you know, schhool work, surfing on the web for cheats, etc.), how much of your brand-spankin' new Hercules Prophet II with 64MB DEDICATED RAM (wah! can ya buy me one?) is in use? Probably not even half, and that's if you go for the highest resolution and color depth. Why not utilize these for something? 3D modeling would be hard to implement intelligently, but it would still be possible.

    And a vicious cycle gets started here. Companies like this idea, put out all of their power-munching projects, and we end up with an inbalance with too much needed power. With all these different programs, usage will be split. Then, when enough users and power equalizes, the projects will dry up, leaving some company (probably fresh out of IPO) with no cash, no revenue stream, very little property, etc. Critics will shoot down distributed computing fast. In a few years, someone will try it again. We'll repeat history. A bit apocalyptic, but realistic.

    ProcessTree, if they ever do pay, may have the right idea. This is a great way to fund micropayments. If you're running low, let your computer run overnight and your account filled back up. Unfortunatly, we'll never see this properly. If PayPal is dominant, they'll have a high surcharge (ever look at the fine print on a credit card application? A must-read...). Also, how can we create a unit without trouble from the US government (you know about this problem if you know about experts-exchange.com. Here, you get points for answering questions, and spend another type of points for asking questions. They wanted to just make one type of point, but the IRS(or some other goverment agency) said to do so was illegal.) Wah! The best part!

    Finally, like has been said before here, no one is paying yet. We may never see one that does in our lifetime. Why? Internet companies are stabilizing and becoming sensible. Giving money for borrowing a few wires? Sounds silly.

    Don't get me wrong, I like the idea. But this rant explains my problems.
  • So is this why http://www.dcypher.net can never get any press on /.?
  • Since Hemos brought distributed.net up in a "subliminal message", it made me feel like doing a little ranting. Seriously though, I'm still trying to figure out why so many people are still wasting their idle CPU cycles on the RC5-64 effort. So far, d.net has spent THREE YEARS working on cracking RC5, and they have only gotten through 30% of the keyspace! At the rate they are going, it will probably be at least another year before they find the magic key that unlocks the encrypted message. And when that happens, so what? The whole idea of the project was to show how weak existing security encryption is, but instead, d.net will have ended up proving quite the opposite. Spending four years and using the resources of about 100,000 computers just to break a simple security key won't look very impressive in a press release, and it DEFINATELY won't scare the government into thinking that existing encryption is too weak. It seems that this project has de-evolved into a bragging contest on who can crack the most keys. Gloating comments like "My computer can crack RC5 faster than yours" or "My team is higher in the rankings than yours" seem to be all that's left of this project. A major waste of time, if you ask me.
  • People allready offer banner clients.
    Some make money some banners trade for services (free ISPs)
    The problems with them are the timeout.. forcing you to click on a banner every once in a while.

    If instead you were asked to trade cycles for bandwith..

    You know who to call if they have a back door...
    Same rules that keep open source develupers from sleaking back doors into software will keep closed source clients from doing anything more than using your procesing cycles...

    If you discover otherwise... class action lawsute...
    Then you make some sereous money...

    This is good. Admitedly for closed source.. it might hurt open source a tad..

    But it burns Microsoft...
    Basicly why buy Netscape or Opra when you have IE for free?
    Thats what keeps Netscape free... but... Netscape with a distributed client... can generate money and be free..

    It could also mean we'll see more Linux software and games ported to every Unix platform including Solarus.
    You are sharing processing cycles in trade for software... Linux, BSD and Solarus boxes tend to be left on and running while Windows boxes tend to be turnned off..

    This is less a stability issue and more a geek factor... Macs get in the 50/50 range as they have a strong Geek, Busness and newbe attraction..
    Avrage people turn things off.. lights.. TV... radio etc...

    Windows users turn computers off when they are done like turnning off a TV or turnning off the lights...
    *nix users tend to leave computers running as if it were vital hardware...

    Any computer can run as an alarm clock.. *nix and Mac systems are however more likely than Windows to run as such...
    Simply becouse of the kinds of users who run Windows...

    Anyway so this translates into prefering systems that stay on all the time normally over systems that get turned off...

    Why support 11,000 users who only provide 1 to 2 hours of idle cycles... vs 1,000 users who provid 24 hours of idle cycles a day... in some cases 48 hours of idle cycles a day.. (Two computers... and the occasional time bender)...
    It costs money to support users... and while *nix users support themselfs you gota convence the avrage CEO of this..
    So basicly paying to support 1% of the users who represnt 80% of available idle procesor time is a really good deal..

    and once they realise we don't accually need support... it'll be even better...

  • I doubt any company can sneak a distributed computing client onto a PC; it takes one person to notice and publish their findings. The backlash against the company would be huge.

    I occasionally run a load monitor, and I suspect many others do.

    On a device like a WebTV client, there is no way to run a load monitor. The software is completely controlled by the manufacturer, and probably embedded into the device.

    In addition, most of the people accessing the internet through such a device are unlikely to have the computer literacy to notice, or even care. So it makes sense to exploit the idle time of a device like that.

  • Quite the opposite, most companies invest a huge amount in computers that are idle a large amount of the time.

    Never said everyone doesn't want to get paid, but there are huge reasons not to be the one doing the paying

  • With enough patience, skill, and a good debugger, it is always possible to reverse engineer a binary.

    Yes, but is it legal? DMCA, EULA, and UCITA make reverse-engineering illegal, and the software would probably detect most common debuggers.

  • If paying for distributed CPU cycles becomes the norm, and every appliance you ever buy eventually has a powerful computer+internet connection, you could feasibly get those appliances for free.

    If the cost of the processor cycles was greater than the cost of the computers themselves those companies wouldn't be giving the computers away; they would be building them, keeping them and selling the processor cycles themselves.

  • Yes, but is it legal? DMCA, EULA, and UCITA make reverse-engineering illegal, and the software would probably detect most common debuggers.

    Do you even remember how this thread started?! Someone worried that because distributed processing schemes might be closed source, people could become unwitting participants in Echelon or Carnivore. I disagreed, pointing out that no intelligence agency would let software processing potentially classified data run on untrusted computers. Allow me to clarify: intelligence agencies are paranoid. They assume that they have enemies with skill and resources. They would assume that these enemies would participate in such a distributed scheme to gain access to whatever possibly secret data was being processed. The fact that it might be illegal to reverse engineer the software would be irrelevant. It's illegal to break into cars, but I'm willing to bet that the NSA, et. al., don't leave classified documents sitting around in the trunks of cars on the side of the street. Finally, intelligence agencies assume that they have enemies competent enough to step through the code using a decent debugger, noticing if the code is trying to check for a debugger, rather than just running the app full tilt and then attaching Turbo Debugger, or whatever the hell you're thinking.

  • My SETI client IS my load monitor.
    Undisturbed, I can do about 10% an hour.
  • Imagine walking into your average Best Buy and EVERY applince there is free.

    Ain't gonna happen. Why? Well - there is no need of selling this then. The distributed computing companies can walk into your average Best Buy store as you say and get the hardware for free themself.

    The main principe of the current "for free" programs (Internet for free, mobile handset for free, info-servers for free) is that you pay the money in some way eventually. On connected services, by watching comercials and so on.

    With free computers paid by computing cycles, the distributed companies actually do not need you at all. :)

  • but I do wonder with these pay schemes if the payment will actually be enough to cover the cost of electricity.
    Those of us with broadband connections tend to keep our machines on 24/7 anyhow, so this isn't an issue.

    Making money while I sleep...
    Sounds like a nice idea.

  • I was thinking about a method of dealing with sabotage. Why not send the same problem packet to two (three?) different machines signed up with different IP domains. If the answer packets don't match, then send it out to two more machines. This would (I think) take quite a tremendous effort to circumvent. Of course, it requires more than twice as many cycles, but the ability to release full source clients may make up for that.

    I quote the distributed.net FAQ [distributed.net]:

    Doesn't running the client waste a lot of electricity?

    Many modern computers can enter low power-usage states when they detect they are idle. This mostly involves powering down the monitor, stopping the hard drive, and allowing the CPU to enter a slower idle state that does not produce as much heat. Running the client on a normally idle should not affect its ability to power down the monitor, which is a significant part of the power usage.

    However, the hard drives of a power-saving machine may be prevented from spinning down if the client continues to periodically save or load blocks to disk. If you have multiple hard drives in your machine, you may want to consider ensuring that your client buffers and logs are on the hard drive that is most likely to have other activity as well (such as your OS swap file, or OS System directory), allowing the other less frequently accessed drives to spin-down unaffected. You might also want to consider enabling the Client's "nodisk" mode so that it only uses RAM for its operations, but be aware that your work may be lost if your computer crashes or loses power (wasting the power and idle cycles that the client could have used for productive work if it wasn't lost). You might also want to be aware of the fact that spinning up/down your hard drives can actually reduce its lifetime.

    Additionally it is true that the Client will also probably prevent your CPU idle from entering its reduced power consumption idle cycle mode (sometimes called "HLT" mode in x86 processors). However, the actual power consumption by the CPU processor alone is actually a minor portion of the total usage by the computer (much less than 20% usually), and entering the lower usage idle mode only reduces that amount slightly. Note that this idle mode is unrelated to the CPU frequency-lowering that is sometimes done automatically by APM services when no user interactivity is detected (the client will not interfere with this reduction). You should also be aware that sometimes computer fans run only when excessive heat is detected (such as from a continuously operating CPU or hard drive). These cooling fans are an additional source of power usage.

    Overall, the actual difference in power consumption by computers that are running the client during periods of time when they are normally left on (for unrelated purposes) is very minor....

  • I can't comment on paid distributed computing, but I can vouch for alladvantage paid ads. Not a large check [in fact, they changed their rewards recently to make them lower :(]
    The best thing is that you can easily filter out the ads with a proxy. Money wants to be free :)

  • We're only a couple of steps away from not owning our own computers. If you think you dislike having someone dictate when or how you can watch your own DVD or use your own word processor, how do you think you'll feel when your new PC comes with a mandate from its maker that you MUST let them run whatever idle-time daemons they want? That you MUST let them use your internet connection whenever they want? To some extent, this is already happening. If this trend continues, we're all going to be paying for our CPU-seconds again, just like in the good old 1950s.
  • Subject says it all :)
  • What is thought of running these types of pay-for-idle processor time setups at work. I know that a lot of people set up distributed.net or SETI clients at work (machines not owned by themselves) I wonder if companies will mandate that all computers run a clients that pay you back. The money could significant if you are at a site with several hundred computers. And what are the implications of making money off your employers spare computer cycles?
  • We are consistently accelerating our chip schedule because of these mammoth computing resources," Intel vice president Pat Gelsinger said at an Intel conference last week. "We sped up validation on (our) latest chip by eight weeks."

    Hey intel-didn't you recall your latest chip because you didn't do enough validation before you released it?

  • ...the system has to be highly redundant. Send each calculation job to, say, 10 random nodes. Grab the 10 outputs. If one of them looks different, discard it.

    Repeat offenders would be shut down from the calculation ring and notified that either their piece of code is malfunctioning or has been tampered with.

    This way the client software could be open-source'd without any problem. I actually think SETI@Home does something like this.

  • Not true. Most OS's execute (Win9x is the exception) a HLT-loop in idle time. Halt puts some parts of a CPU in sleep mode, where they consume significantly less electricity than normaly. Buck a month would not cover the increased in your electricity bill.
  • What the Slashdot story and the underlying CNet article don't mention is that nobody is actually getting paid yet. I got all excited when I read these stories, and I proceeded to visit every company site named in the CNet story. None of them are paying out yet, and none of them even have pay rates figured out. Save your time.

    Going further, I did a search on Yahoo, and hit just about every company listed under Distributed Computing. None of them are paying out - they're just taking in money from investors.

    The Slashdot story is only partly right - there is indeed money to be made from this idle-cycle scheme, but it isn't going to be made by folks like you and me. It's being made by the companies who are suckering investors into this. Of all the sites I went through, I counted a rough total of over sixty million bucks in funding that the companies had gotten from investors. And not one dime has been paid out yet....
  • thats probably why distributed.net is sending each ogr stub twice and discards it if they are not identical when they are returned.
  • My bill is about $300 for 3,000 kwh per month. Using my MIT PhD, this gives a marginal rate of about $0.30 per kwh (yes, this is simplified, but given the itemized transmission charges, generation charges, fuel adjustments, warthog taxes, all all the rest on your bill, not a bad approximation). A P2 333 will take roughly 16 hours to do a seti set under Windoze and 12 hrs to do it under BeOS (since it is the same machine it must be M$ "innovation" tax I guess...). Lets figure it as 12 hrs, lets further figure that there is a 200 watt load for this. This is thus 2.4 Kwh for the set or $0.72 per seti set of electicity. If you are someplace that needs air conditioning, figure the cost of the heat removal also, if you are heating, give yourself a credit. A 450 Mhz G4 will do it in 6 hrs, thus $0.36 for the sake of argument. Seti scales directly with the speed of the cpu, but the Athlon and P3 etc. machines are more power consumptive than the standard P2, so I would assume that although a 750 Athlon does it in 6 hrs, it requires 300 watts to do it. On average, the "fair price" to cover the electricity seems to be around $0.50 per seti equivalent set. A bargain compared with the $1000+/cpu hour that things used to cost, but I suspect that break even is only going to be on machines whre someone else pickes up the electricity bill.

  • I run the Popular Power client on both my home and office computers. PP basically goes after both the greedy and altruistic tendencies in all of us by allowing the user to set whether they want to maximize profit or benefit non-profits more. Nice feature but since there isn't any paying gigs as of yet, currently useless. PP was the featured company in the Wired Magazine article which you can find here [wired.com]. The client keeps statistics of your usage so there's definitely a competitive incentive.

    Basically, I figure "Why not?". I'm not using my home computer while I'm at work, nor my work computer while I'm at home. Given the necessary security measures, it's nice to be of help. I think this will be a technology widely used in the future.

  • There was a thread [slashdot.org] about the problems with open source and hacked clients in an earlier discussion. I'm not sure if it's much help.

  • You're looking at it from the wrong angle here. First, unless you paid the company, you wouldn't be able to distribute a task. Second, the whole point of these things is that they are distributing packets to you, and you get paid for processing those packets. You'd have no idea what you're processing (well, you might, but most likely won't). It's meant for companies who need, say, a movie rendered quickly, they send a different frame to each computer waiting, and it gets done quickly.

    Your whole post doesn't make sense because you either a) didn't read the article, or b) just don't get the concept.

  • If you look at Andover.net's financial disclosure reports, you'll find that Slashdot, which earns revenue through solely ads, is profitable. Therefore the model, if properly executed, can be profitable.
  • That's why, for this to work well, you'll need to arrange for the distributed app code to run in a standard secure 'sandbox'. Doing it in a Java JVM would work, for example. A JVM can easily be set up to limit access to (and hence potential damage to) local system components.

    Interested in seeing it sooner? mojonaton [sourceforge.net] is an opensource project.

    The most difficult part (IMHO) of writing a payment for cpu cycles type of system is sandboxing the code so that it can't intentionally or unintentionally do anything evil (ie: it needs to be MUCH more secure than Microsoft Outlook ;).

  • Mojonation [mojonation.net] look like they are ahead of everybody in this game. They are ALREADY paying people for thier HD space / spare CPU cycles.

    From the Mojo website:

    You can sell your idle online resources to others for Mojo (the internal currency), and then can trade Mojo to download content yourself or exchange it for cash after the Beta test is complete. This makes it easy for anyone to start getting Mojo. No paperwork to fill out. No wait. Just start running the software and you can begin earning Mojo as other users buy services from you.

    Community members contribute resources by running one or more services on their computer. Most services can be operated from behind firewalls and with modest Internet connection speeds and can be launched and start earning Mojo for you with a couple clicks of the mouse. Anyone, even those connected by modem, can offset their charges by providing services to the system. Examples of services that users can provide to earn Mojo include:

    • Publishing and storing content for the Mojo Nation data service.
    • Actively caching popular content.
    • Hosting a tracker service to help other users find particular content or resources
    • Providing a relay service, so that users who work behind a firewall or use a client-level anonymizer can operate services.

  • Using the RC5-64 challenge as an example...

    One way to check the security of completed blocks is to have each block also calculate some incidental security check.

    For example, as well as making note of all keys that decrypt to "The secret word is", it could also make note of all keys that decrypt to "The". In each block of 2^32 keys, there should be around 256 which decrpyt to this.

    If a returned block contains (say) 200 or more keys which decrpyt to "The", these can all be checked by repeating the decrpytion of only these 200-or-more keys (which should take milliseconds). If any do not decrypt to "The", then the returned block is definately bogus.

    If all the 200-or-more match, then it's reasonable that the client did it's job properly, since there's no way (in theory) to work out which of the 2^32 keys would result in this decryption, without going through them all one by one, which is exactly the job the client is being paid for.

    The returned block contains below 200 keys, all of which decrpyt to "The" then this returned block may be bogus. It's possible that this key block is a freak where only a few keys decrypt this way, but it's more likely that the client stopped short and retrurned the incomplete block, hacked to look like a completed block.

    As an extra security check, the central server could re-issue a proportion (say 10%) of completed blocks again, to see if other clients give the same result. If two clients return different completed blocks for the same job, then one of them is bogus. You can run the block yourself to find out who.

    Re-issuing will result in a slow-down, so is best used sparingly.

Even if the clients are theoretically secure, and no person gets enough information to understand what the data or results is, MANY (many, many) companies are so paranoid about their intellectual property that they'll never do this.

    Also, it didn't really get much into the fact that not all problems are particularly well suited to distributed computing. In fact, I'd say the majority of all computation problems AREN'T easily suited for distributed computing. Either because you'd lose the computational benefits due to the overhead of transmitting really large blocks of data or the algorithm is too dependent upon being feed serial data.

The official client binaries, OTOH, are considered "trusted binaries" and may in the near future be digitally signed.

  • Nothing too new in that article save for the commercial aspect, which was arguably inevitable. I'll be more impressed when people start building distributed computing clients into embedded devices that need to be on all the time. Distributed projects aren't about getting fast hardware hooked up, but about getting *huge* numbers of mediocre devices working on little bits of the problem - so things like microwaves and VCRs and even car trip computers could, given a way to connect, out-CPU all the supercomputers in the world. That raises interesting issues of how to pay people back for the use of the electronic gizmos they've bought. Even though I don't always like the leased or licenced (as opposed to owned) approach to buying hardware devices (or software for that matter), it does make a natural fit here, where you could receive a discount on the lease price for the use of a device's spare CPU. Companies that make hardware would probably contract out the actual distributed networking and computing aspects.

    That also leads into the other point, about wasting power and generating heat. Some devices really are intended to stay on 24*7 (whether they always really need to or not), so they may as well be recruited for this. Things like SETI@home, on the other hand, strike me as very wasteful - not only will people leave their power-hogging computer on & awake where they might not otherwise, they'll even stop the monitor from sleeping so they can see the "screen saver" display (and here I thought we'd finally gotten over burning power for useless animation). Wasn't there a /. article a short while back on the burgeoning power demands of all our overfast computers in the years to come?
  • You hit the nail on the head with the last part. If the incentive is good enough, people will install all manner of questionable crap.

    Also, don't count on too much information being released on the clients. Any company who is a client of one of these CPU-for-dollars service will want to believe their data is accurate and that the people running individual clients can't steal the majority of their precious intellectual property.

    Most of the free 'for fame & glory' distributed projects wont even release source code because they are afraid it will cause people to send in garbage data results in an attempt to cheat to get to the top of the list. And putting in some sort of fancy security layer on top of the client to make sure data is valid would likely invalidate most of the gains of a distributed project, because you'd burn tons of cycles on the server trying to do re-validation...

  • ...data to be processed on untrusted computers whose owners could, closed source or not, reverse engineer the software and gain access to presumably valuable information.

Wether busy or idle, most computers spend the majority of their lives waiting for human interaction -- Not crunching numbers.

    While the idea for large-area distributed computing is cool, of what practical purpose is it? Its not going to help me do the things I do any faster than I would normally. Its not going to help me browse the web any faster, read the daily news any faster, dial out any faster, sell CDs any faster.. The only sort of applications (it seems, perhaps i'm being short-sighted here) that could benefit from this sort of thing are 3D modelling/rendering applications, graphics apps, and scientific applications, all of which require tremendous amounts of computing effort.

    To me, it would probably take more time for my machine to "distribute" a task and reap the result than it would be to perform the task singularly with my own box. Sure, if I had some enourmous image I was doing work on, it might be a good idea.. But for most things, the overhead incurred by distributing the workload over X number of remote machines via the net would be more time-consuming than just doing it locally on a single box with multiple CPUs.

    Mind you, I have nothing against the idea. I think it rules. But i'm at a loss to find any particular mainstream usage for such a technology. Most of us are leaves on a tree, not branches. We're seated at the end of the line when it comes to the life of a particular piece of data.

    On the legitimate side of this, the company that is most likely to succeed is the one that markets itself best to corporations. In my limited experience, most corporations just run lame screne savers. If you go to them and explain that they are losing money running screen savers, they will be happy to oblige.

    On the sinister side of this, the distributed processing company that integrates an employee monitoring system into the client and markets that to large corporations will probably do pretty well also.

    You don't have to cover the total cost of the electricity anyway. You just have to cover the difference between the cost of power consumed at idle now, and power consumed running the client. The question then hinges on how well the "power saving idle mode" works on most PCs. Anybody got the numbers?

    Assuming that the numbers make it beneficial for corporations to run the client, the question may then be one of whether or not there is sufficient demand for distributed services. Right now, render farms and weather forcasts are the two obvious commercial applications.

    The real (hidden) costs:

    • Electricity - min 5-10$/month
    • Server Bandwidth - SETI uses about $22,000/month of taxpayer funded bandwidth last I asked, more by now.
    • User Bandwidth - not everyone has Cable/DSL ya know. Bandwidth isn't that cheap outside the .us.
    • Server and User Hardware - also not free, wear and tear, etc.

    Why no company would ever touch it:

    • Privacy/secret loss - you cannot do distributed computing and not give out your raw data and trade-sercet code. Period.
    • Security - you cannot do anything to prevent bogus results and things from inteligent crackers. Period. If there is money involved, peoelpe will try hard to cheat.

    So you have huge hidden costs, total loss of any capitalist advantage, and huge headaches for the admins. Keep dreaming folks.

    Can open, worms everywhere:

    So maybe the toaster can tailor the ads to match your food choices? If you put a lot of bread in the toaster, will you be shown ads for jelly? Perhaps something like the supermarket checkout thingies which give you coupons for competing brands. If you're always microwaving Celeste Pizza for One, maybe your microwave will force you to watch an ad for Stouffer's French Bread Pizza?

    And I don't even want to think about what the privacy advocates are going to say about this.

  • Electricity - min 5-10$/month

    Server and User Hardware - also not free, wear and tear, etc.

    "Real" supercomputers have these costs too; if you count them here, you should add them to the cost of "real" supercomputers.

    Server Bandwidth - SETI uses about $22,000/month of taxpayer funded bandwidth last I asked, more by now.

    User Bandwidth - not everyone has Cable/DSL ya know. Bandwidth isn't that cheap outside the .us.

    Asymptotically, bandwidth is cheap. The cost of bandwidth is dropping by a factor of two every 8 months (Gilder's law), while the cost of computing power drops by a factor of two every 18-24 months.

    The bigger issue is latency. Partial pivoting (ie, linpack) *must* have low latency. Many other algorithms also require low latency.

    The big problem is going to be finding algorithms which work even with high latency interconnects.

    (1) It seems that most posters fail to appreciate that this form of distributing computing is limited to problems which are essentially "trivially parallelizable". Anyone who has done parallel computations knows that MOST interesting parallel algorithms MUST exchange information with other processors while doing useful computation. Both the bandwidth and the latency over the internet will NEVER come close to matching what can be found inside a high-end parallel machine where the processors are all mounted in a single unit. The performance of any "coupled" problem, be it a traffic simulation or a climate model, will be absolutely dog poor on these widely distributed computer networks.

    All said, this is still a very cool concept for SOME projects, like distributed rendering for films, and analysis of vast quantities of data (ala SETI@home). One shouldn't underestimate the marketing value in a distributed rendering project for a film, either! (Who wouldn't go see a film they had helped render on their PC! Especially if one could "preview" the result as it was being rendered.)

Some electric companies have even started PAYING their large corporate customers to take days off and to shut down their power supplies so that these electric companies can keep electricity flowing to the general public without causing safety risks.
