Am running CUDA and it seems to be running okay, but have done three WUs and 1 has finished, one errored out and the other is growing in times, and sitting on 18 secs CPU time. IS this normal or am I experiencing a build up to an error? |

What you are seeing is the CPU time used, not the GPU time used... CUDA uses a small amount of CPU to help it along, and BOINC records this time and GPU time is not recorded. Though in reality, you are doing MUCH more processing than 18 seconds. |

Am running CUDA and it seems to be running okay, but have done three WUs and 1 has finished, one errored out and the other is growing in times, and sitting on 18 secs CPU time. The task that is stuck at 18 seconds is probably a Very Low Angle Range task or VLAR (0.1 angle rangle and below) like the ones you have with a compute error, and you should abort any tasks like those. You should also reboot after having one. It's also been suggested that you use the batch file lised in several of the threads so you can spot these tasks and abort them before they run. This thread has examples of those batch files. |

Thanks Byron Just ran it and "terminated" 10 WUs. Am using your amended version of the one that someone else quoted from someone else *grin* SO, shall now sit back and see if this makes compute errors a partial or full thang of the past. Thanks for the help. |

There is a update of a mod version from Raistmer http://setiathome.berkeley.edu/forum_thread.php?id=51289&nowrap=true#853108 This will abort VLAR if it detects them and you dont have to do it manual ... Before you install that make shure you have lastest gfx drivers ... Set seti to NNT (no new tasks), wait until all tasks at your list are finished, uploaded and reported. Then quit BM install the update, start BM and set seti to new tasks allowed ... |

Thanks Byron If you continue to have problems even with the script you can still try the lastest CUDA modified application V5a VLAR version |
