My error rate on the gtx460 was certainly higher with earlier versions of the driver than with 314.22, but since I updated to r1761 it is hard to say which made the improvement. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

Let's see if the driver update fixes it. It's hard to say what's going on with the AP tasks with just one to look at. But, you're also getting a higher than normal inconclusive rate on the stock 6.10 gpu application as well as the optimized version that you stopped running, so you need to watch that to see if there is improvement.

That is where i download from.. My GPU software is linked to the website. All i did was clicked on "check for update's" |

I was not aware there was an update version for my GPU I just updated it. And about the Lunatic's program. I know some people don't have issues with it where as others may have, ever since i installed that program i had problems with BOINC Manager one after another. As it is right now i am doing just fine without the program, better even. See this thread; OpenCL AstroPulse crash after processing completion You can probably avoid most of those Access Violation (0xc0000005) Errors by adding parameters to your ap_cmdline_6.04_windows_intelx86__opencl_nvidia.txt file. |

Those manual installs is not my thing. I don't trust my self to do them.. not a programer even for copy & paste. I'll stay with the irritating issue i have unless it's an install type app. |

I'll stay with the irritating issue i have unless it's an install type app. There isn't any type of Install. All you are doing is adding a line of text to a text file that has already been installed. The text file was installed, by default, for the sole purpose of adding such lines of text. They can't add the correct line of text during the install because it is different for every class of GPU. YOU have to add the correct line of text for YOUR GPU. Sorry, there isn't any other way. You add the correct line to the file or, it doesn't happen. The instructions are in every new App package released, the most recent is here, Current OpenCL apps are available for download on Lunatics again

So what is a 'compute unit'? |

And the number of compute units for a specific card are found where? GPZ? Documentation? Nothing I'm coming up with says "X card has Y compute units." |

And the number of compute units for a specific card From your stderr_txt from one of your completed Wu's. Claggy |

There are a couple of useful Wiki pages: Comparison of Nvidia graphics processing units Comparison of AMD graphics processing units The Nvidia (cuda) page lists "SM Count - Number of streaming multiprocessors" for each card, but whoever maintains the AMD page doesn't seem to bother with a compute unit count. |

Too late to edit, but I've had a PM to say that the compute unit count can be found on the AMD wiki page: The column "Config core" has three numbers separated by colons; Unified Shaders : Texture mapping unit : Render Output Unit (ROP). |

Too late to edit, but I've had a PM to say that the compute unit count can be found on the AMD wiki page: The AMD wiki and GPU-Z might say 16 ROPs for my HD7770, but OpenCL says 10 Compute Units, so they might not match. Claggy |

There are a few exceptions, especially with the older GPUs. OpenCL says my NV8800 has 14 Compute units. On those occasions when I run an AP on that card, anything over an unroll of 6 causes the entire computer to become unresponsive. Even though I'm not using the monitor attached to the 8800. Using an unroll of 6, the GPU load is maxed out anyway, so, there isn't any advantage to using a higher setting. The other older card, the ATI 4670, is listed at 8 Compute units. The 4670 is maxed out using an unroll of 4, and I think I even get warning notices with a much higher setting. That's covered by the line 'Your mileage might vary' in the Readme. That's another reason those Command Lines are not set by the Installer. |

Thank you everyone. I'm sure these answers will be as helpful to others as they have been to me. Again thanks. |
