Just so everyone knows, ATI released a new driver for their GPUs yesterday, version 11.2. So far, I have had ZERO driver restarts when running the multibeam application, even when I am running 2 tasks per GPU on the 6950. This is very good news!! Thats so true! It's bad programming that you could not install the new drivers just over the old ones! I even had to use GPUclean before it worked!! I had to switch back to one job at a time because there were some strange crashes. Win7 64 HD6970 |

I am seeing one glitch though running a GPU WU and watching a video on youtube is a no no. I completely locks my computer down In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

I am seeing one glitch though I have the same problem with both the 5870 and the 6950. I've just learned to suspend the GPU processing for a bit while I'm watching a video, or watch it on one of the nvidia machines, which really don't have any issues with playing a video while running seti. Odd, isn't it? -baron_iv Proud member of: GPU Users Group |

my 5850 never killed a WU while I watched a video. This really is odd. In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

2 all who experience various lags - what period_iterations_num do you use? |

For some reason its not using my ati 4650 on my second computer. The app occupies a whole cpu core (0.05 is set in the app_info), the gpu usage stays at 0%, and the completition at 0% too. After an hour i stopped the WU. App info is from the release page, i only deleted the platform line. Am i forgetting something? Edit: boinc 6.10.58 catalyst 11.1 win7 32 |

-period_iterations_num 2 try more cause it's the purpose of this setting - to fight with lags. |

Right, it has only 128. Does this mean its useless for the "AP GPU ONLY" app too? I tried the hybrid app once. It works, but its not really using the gpu. |

No, only r177 of MB app is affected, AP should run OK. |

I tried the hybrid app once. It works, but its not really using the gpu. The Brook-based hybrid application does use the GPU, but only in short bursts and only for a very small percentage of the overall processing time. But unless you have other applications which can make full use of the GPU, it's better than nothing when it comes to speeding up Astropulse on a GPU where the OpenCL application is not an option.

I'm reinstalling the drivers. I'm getting locked up while I'm away from my computer. I attempt to bring it up and the screen stays blank. another thing is the CCC doesnt start with the computer as it should In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

I got report that with new Cat 11.2 there were no driver restarts with r177 HD5 still, will see how long it will be so :) It looks like somehow the drivers are sensible for overclocking the CPU...! I had to clock back from 4G to 3.5G before it was stable. (Or maybe my poor OC-capability) result oke though; http://setiathome.berkeley.edu/result.php?resultid=1807173127 With 10.12 I could do 2 jobs at a time, but in the processes of upgrading the driver I went back to one to avoid crashes. I do not trust this driverversion yet.... |

Looks like all of a sudden the app does not like vlar units on my system, I have a string of vlars that all crash at 29:42 with a -177 error. http://setiathome.berkeley.edu/show_host_detail.php?hostid=5338281 |

You're got: <message> Maximum elapsed time exceeded </message> According to your Application details for host 5338281 you're only just completed your 10 initial validated tasks, !?!?! but you're also got 30 Consecutive valid tasks!!!! now the server has scaled your work, it should get better (Edit: maybe), but you'll need to use Fred's Rescheduler to fix any existing work, and new work too, Claggy |
