I'm looking for this in the logs now. This is probably an artifact of the way are BOINC 6 OpenCL kludge is implemented... See BilBg's post earlier, you need to try installing newer drivers, But Not any newer than Cat12.1 (ATI OpenCL Support is removed from Cat12.2 and later on XP drivers) Then use GPU-Z or GPUCapsViewer to see if you have OpenCL support. Only Boinc 7 and later can detect wether a GPU has OpenCL support, The Boinc 6 Kludge is that if you assume a GPU has a particular driver, then OpenCL Support should be there, But there is always a chance some dimwit only installed the driver component, and didn't install the OpenCL runtime (They were available at one point as separate downloads) The Server Bug is that because Boinc 7 didn't detect OpenCL support (and so wouldn't send opencl_ati_100 Wu's), it also shouldn't use the Boinc 6 Kludge and send ati_opencl_100 Wu's.

Took the Suggestion. | |

Took the Suggestion. If you dont have OpenCl support then yes, you need to uncheck the "Use ATI GPU" but if you have more than one computer you may want to set a different venue for this host so this setting wont keep you from crunching in other GPUs that are OpenCl capable. ____________  | |

In new ATI Catalyst Driver is no open CL driver included. | |

Now that I've read the posts on this topic I'm inclined to believe this BUG is the reason my Laptop's onboard video chip no longer works. :-( | |

Now that I've read the posts on this topic I'm inclined to believe this BUG is the reason my Laptop's onboard video chip no longer works. :-( Rubbish, Boinc doesn't detect a GPU on any of your hosts, and they have never received any GPU Wu's: Computers belonging to Sean Farrell Application details for host 6706265 Application details for host 6714919 Application details for host 6705145 Claggy | |

Now that I've read the posts on this topic I'm inclined to believe this BUG is the reason my Laptop's onboard video chip no longer works. :-( Highly unlikely. If your old T61 didn't have an OpenCL compatible driver, likely you were never sent any GPU work. Even if you were sent GPU work by accident, it would have never processed on the GPU and it would have simply erred out. Your video chip failing had to be for other reasons. | |

Fixed by unchecking. | |

I find that the dates and times do not match the ones listed in the link. Everything there will be left alone then and thank you for all the information it has been permanently filed in the old aging braincase. The upside is that in the next few days I will be getting in a GeForce 295GTX dual GPU 1.7GB memory card. I would get something better but that is the top end card supported by my motherboard. Final question concerning the operation of BOINC itself. In the last 17 days I have added 6 projects to my primary workstation but left the other machines just running SETI as I figured I had enough machine power to run them with damaging my SETI WU credit score. In fact I tweaked the settings for Resource share so that SETI had 70% of the resources and the other 6 projects had 5% each. But I am finding out that BOINC seems to be completely ignoring that setting and instead allocating time round robin between them all and result is that my average credit for SETI has dropped from nearly 4500 down to 2000 and the Einstein one has jumped to 3900, 3 of the others are together under 1000 and 2 are not generating any work. Was I wrong in believing I had read that you could force BOINC through the resource share option to partition out the work in the percentage that you wanted?

Fixed by unchecking. This is not a real fix (to uncheck 'Use ATI GPU') Your 'AMD ATI Radeon HD 4600 series' is listed as (hardware) supporting OpenCL: http://developer.amd.com/sdks/AMDAPPSDK/pages/DriverCompatibility.aspx Listed devices are: ATI Radeon™ HD - 4600 Series (4670, 4650) Which is your model? Can you give GPU-Z screenshot? (click 'Photo-icon' in the top-right of GPU-Z, upload to ..., copy link) Here is shown 'OpenCL version - OpenCL 1.0' (apparently valid for all 'Radeon R700' chips): http://en.wikipedia.org/wiki/Radeon_R700 ____________   - ALF - "Find out what you don't do well ..... then don't do it!" :) | |

Was I wrong in believing I had read that you could force BOINC through the resource share option to partition out the work in the percentage that you wanted? well, that's the idea...but when was the last time BOINC actually did something you wanted it to? that function doesn't work correctly for me either. two of my machines crunch LHC@Home Classic along with a handful of other projects. i used to allocate 90% of the CPU to LHC@H and the remaining 10% to the other projects b/c LHC@H hardly ever sees new work...so i wanted to be sure that my machines would give priority to LHC@H work whenever it is available. so one would think that BOINC would prioritize LHC@H work over all other work whenever its available, but does it? nope. instead, LHC@H doesn't even download new work on the rare occasion that its available, and all the projects that appear to have a minimal CPU resource share continue to grab more work... ...interestingly enough, one day i decided to reallocate the CPU resources such that all projects have an even share...and what do you know, all of the sudden LHC@H starts getting work when its available...go figure. ____________  | |

6.04 (opencl_nvidia_100) Yes, of course, the AstroPulse v6 6.04 (opencl_nvidia_100) / Windows app was just released. (it was available in some 'beta' form only for people/testers using the optimized apps) ... in the next few days I will be getting in a GeForce 295GTX dual GPU 1.7GB memory card. Why do you think so? Don't expect that your motherboard docs (.pdf) will include all the video cards it can accept. (it will list only those video cards available at the time the motherboard was manufactured) You can use PCIe 2.0 video card in an PCIe 1.x motherboard. (my PCIe 1.x motherboard is made 2006, my PCIe 2.0 video card in it is made 2011 (or 2012 ?)) Was I wrong in believing I had read that you could force BOINC through the resource share option to partition out the work in the percentage that you wanted? BOINC is 'supposed' to respect resource share in a long term (weeks?). ____________ - ALF - "Find out what you don't do well ..... then don't do it!" :) | |

My PC hasn't downloaded any work units from SETI in the past week. The GPU is Nvidia GTS450 and the drivers are 301.42. BOINC is version 7.0.28 (x64). Is there something I should do? | |

You could try Milkway, at least its always have work to do (GPU+CPU) so you will be sure there is no problem in your host configuration. | |
| ID: 1275580 · | |
|
Yes, Milkyway I have and it's working like a good 'un. It has 21 tasks in the list at the moment - half complete, half at zero. | |
| ID: 1275643 · | |
|
I've left it to do its own thing, and there was one attempt to get tasks this morning, with the response "Project has no tasks available". If SETI is out of tasks, that would explain the lack of work being done - but I'm surprised. Has it really run out of work? | |
| ID: 1276009 · | |
|
Not out of tasks, just no tasks on the download server at the instant your cruncher called for work. Now that one call has been made it should try again fairly soon, and keep going until your cache is full. | |

The feeder can only hold 100 work units at one time. | |
