Cheers 5pot
----------------------------------------I'm thinking along these lines http://uk.msi.com/product/vga/N560GTX-Twin-Frozr-II-OC.html It's hitting that price/performance/energy consumption/reliability/lack of noise sweet spot... that's the tricky bit The debate is Is the TI version worth the extra £30/$47 ?  I always wondered what those other graphics card slots were for   |

----------------------------------------Have you looked at the latest ATI cards? The wiki page comparing them suggests far higher GFLOPS/Watt than the NVIDIA ones. The HD7770 seems pretty good in price/performance/watts comparisons. [Edit 1 times, last edit by widdershins at Mar 11, 2012 9:46:33 AM] |

David On Folding@home, the Nvidia cards do significantly better than AMD. That is in part because the CUDA wrapper that Nvidia uses is more optimized for that type of work than the OpenGL that the AMD cards use. Maybe it will be quite different here, and I think Nvidia now supports OpenGL also, so maybe that is what the WCG projects use. But they have very different architectures, and I don't think you can just look at the GFLOPS and get any meaningful comparison yet. Have you looked at the latest ATI cards? The wiki page comparing them suggests far higher GFLOPS/Watt than the NVIDIA ones. If you don't need a graphics card right away, I would wait until the Kepler cards come out from Nvidia (6000 series apparently) to see how they compare to the Southern Islands cards (Radeon HD 7000 series) from AMD.

Is the TI version worth the extra £30/$47 ? Only if you get the TI 448 version which is even more expensive.JMHO For reference.http://www.newegg.com/Product/Product.aspx?Item=N82E16814127615 I'm assuming you do know what OC stands for. Overly costly. (To buy and run)

Cheers for the feedback guys
----------------------------------------I've read that the ATI cards produce more GFlops/W but my heart tells me otherwise Ever since they swallowed up 3dfx, and the Voodoo 5 card never arrived, I've been with Nvidia - much like I've been with AMD since that first Palomino'ed core Athlon XP 2100+ blitz my PentiumIII I'll pocket the £30 and put it towards the second one  |

Sometimes, I get a message sequence like this:
3/11/2012 5:49:52 PM World Community Grid Sending scheduler request: To report completed tasks. 3/11/2012 5:49:52 PM World Community Grid Reporting 1 completed tasks, requesting new tasks for GPU 3/11/2012 5:49:54 PM World Community Grid Scheduler request completed: got 0 new tasks 3/11/2012 5:49:54 PM World Community Grid Message from server: No tasks sent 3/11/2012 5:49:54 PM World Community Grid Message from server: No tasks are available for The Clean Energy Project - Phase 2 At other times, I get a sequence like this: 3/12/2012 1:19:29 AM World Community Grid Sending scheduler request: To fetch work. 3/12/2012 1:19:29 AM World Community Grid Reporting 1 completed tasks, requesting new tasks for CPU 3/12/2012 1:19:35 AM World Community Grid Scheduler request completed: got 1 new tasks So my question is, why are requests being made sometimes for CPU tasks, and at other times for GPU tasks, and why do the the GPU task requests fail while the CPU task requests succeed, even though the project is the same, and even though my machine has both a CPU and a GPU? |

A GPU enabled client is ignorant of whether a project has GPU work or not. If it connects and WCG tells it has no GPU work, it also tells the client not to ask again within the next 14 days. If you though hit the Update button it resets the back-off counter for GPU work requesting and sends one again. If you let the client ask itself, it will only ask for GPU work until the 14 days have passed. So until WCG actually launches a GPU version of a research and has work for your GPU [and you've opted in to actually receive GPU work of WCG], you'll continue to see these messages.

Thank you for this very good information.
This leads directly to 2 obvious follow-on questions: 1. When is WCG planning to launch a GPU-version project in which I could participate, and for which project(s)? 2. Is the Update button to which you referred the one under the "Projects" tab of the BOINC Manager? I just want to make sure that I know where to click. |

Hi dkapetansky, yes to both questions.
----------------------------------------For the first question though, a little more info... They're planning on launching GPU with HCC, although as to when, it'll be soon. First though, they've got to 'prepare the ground' (i.e., that's what all the Server upgrade work that's currently ongoing is setting up), then, there'll be a very long Beta period - so as to work out the exact details of what GPU card will/won't work and to ensure that when it DOES launch, that it'll go smoothly (or as smoothly as posssible). So, basically, 'Watch this space'.  |
