So is OpenCL support needed to use the Raspberry Pi's GPU for WCG?
----------------------------------------How much memory does a GPU need access to for WCG? Sounds like Raspberry Pi's GPU will be around 25 GFLOPS. Would that be enough to be of interest. Unfortunately information on the Broadcom GPU is not very forth coming, but hopefully the situation will improve. Maybe if we have the right questions to prob, it will help.  |

My gts 520 had about 100 and it wasn't enough. From their research paper they stated they need at a minimum just to.run was I believe 10 Kb of shared memory. I personally, highly doubt it will be able to run it.

David,
Those are still only the first 10,000 cards that were created :( Us folks who didn't get the memo in the first few hours of preorder will have to wait for a few more weeks/months when they can produce larger quantities. *** again personal post and opinion *** Thanks, -Uplinger |

Thanks for bring this up folks. As an initiative to put small, low power computers into the hands of as many people in the world as possible, this project is outstanding. But a cruncher? Other than thrill of seeing if can be done, I am totally missing any practical crunching use. Please enlighten me.
----------------------------------------I have a suggestion, first test it on CEP2.  Interesting topic. Thanks!   |

"But a cruncher? Other than thrill of seeing if can be done, I am totally missing any practical crunching use. Please enlighten me."
----------------------------------------If it could be done it would be with the idea of only using a few watt's rather than 100 plus watts per PC to make some contribution to the community. Not all of us are obsessed with racking up the maximum points. I get the impression that folks in America don't seem to give a toss about their energy footprint. Whilst the Pi's CPU is not really powerful enough, the GPU may be, but there is no OpenCL support and its difficult to see why Broadcom would worry about support for what is essentially a mobile Soc. Still they are one of the companies contributing to OpenCL so they must have some interest in OpenCL. |

*** personal opinion ***
Well, from reading the about the devices, they use a standard 5 W power, nothing more. They do not even have a power switch on them. which means, if it's plugged in, it's turned on. So, with the potential to being a cheap power efficient video display device (netflix potential device), I could see it being plugged in for days at a time (especially if someone forgets to unplug it which would be someone like me). Thus some calculations can potentially be done in these periods of idle time. Now i have not seen what it can do for a video playback device, but it does say 1080p is supported out of the hdmi. So, instead of playing netflix through my ps3 (which is very power hungry) I can use something more efficient for a simple purpose. Again, it's a new device and it may have a horrible frame rate which would make it not very useful for a video playback device. But for the price, I'm willing to give it a shot and learn something new :) Thanks, -Uplinger |

@KeithSloan :
----------------------------------------If it could be done it would be with the idea of only using a few watt's rather than 100 plus watts per PC to make some contribution to the community. Not all of us are obsessed with racking up the maximum points. Your argument fails me. I would counter that a person who needs such a machine would be using it to improve one’s life rather than use it for crunching. Otherwise just a toy. As to “maximum” credits, big credits means a LOT of work done for the projects and that is why I am here. You? I get the impression that folks in America don't seem to give a toss about their energy footprint. Probably true but certainly not unique to America. To follow your argument here, the best thing I should do is de-install BOINC. Doing that would reduce my electrical footprint by over 90%, save myself $300-600/month and eliminate the associated hassle. You are correct that I do not give “a toss” (a tinker’s damn or a dead dingo’s ass) what my electrical footprint is. I care very much about how to produce/harvest more in a clean, sustainable and life-friendly manner. Then I plan to sell the power to you for a profit.  @uplinger: Ok, that seems to worthy of investigation. I have an idea for a University project. Someone builds a docking station, sticks a bunch of them in it and builds a low-cost, low watt, mulit-core cruncher. Seriously, if you think back to the beginning, that is similar to how GPU crunching took off. Some folks built some boards, stuck some GPU’s in it and the rest is crunching history.  Thanks for the comments. |

Dataman look at your badges versus mine. I am here to contribute but not at any cost. If BOINC was costing me $300-600/month. I would turn it off or at least turn it down. Seems this forum is dominated by people who want to clock up the maximum points. Community Grid should be about a lots of people doing their bit, even if that bit is small. I run BOINC because my machine is turned on for 8 hours a day anyway and having one processors worth out of two going to BOINC does not seem too bad an incremental on electricity. I have another machine that is 99% not turned on it could be doing BOINC work, but it is not because of the cost of electricity.
