I've updated the Nvidia/OpenCL application to 0.52 which should fix the failures on the 23* tasks. |

Matt, how do I find the name of the new 0.52 OpenCL app so I can update my app_info file to download it? I see it listed in the project apps list but can't figure out how to get it without reverting back to no app_info. I use app_info to change my count to .5. Thanks, Keith |

Never mind, I found the download directory. Keith |

All my linux hosts seem to be failing all tasks with the new 0.52 OpenCL app. I have set them to no new work. So far my Windows hosts are doing fine with the new 0.52 OpenCL app. |

Yes, I am having computation errors with all tasks using the new .52 Linux OpenCL app also. Will revert back to the .50 app until it gets figured out. Keith |

I have also the same problem : all the wu 0.52 are failing on my linux ubuntu 10.10 host http://milkyway.cs.rpi.edu/milkyway/show_host_detail.php?hostid=66288 I am using nvidia 270.18 x64 with a GTX260, boinc 6.10.58 x64 and have reseted the project. Any help, please ? |

All my linux hosts seem to be failing all tasks with the new 0.52 OpenCL app.I made a really dumb mistake in the Linux build. Should be fixed now (0.54). |

Matt, thanks for making the new build so quickly and fixing the problem. Running 0.54 quite well now. Keith |

Matt, Thanks for the update. I too was having huge problems. Looking forward to producing good WUs again. Regards, Steve Ubuntu 10.04 |

Matt, Im running 052 ver on 2 gtx 460's and for some reason the cards will not finish the unit? it will keep working untill i close bonic. one unit worked up untill 175%? i could complete a unit in 12 min, now hours. Any ideas how to fix this problem? happy crunching, Landon Oswalt |

Any ideas how to fix this problem?A bunch of workunits were started which were way too big and taking too long on CPUs and many weaker GPUs. The total number of steps in the progress calculation was overflowing the 32 bit limit and wrapping around, causing progress bars to go over 100%. These should go away soon. |

I'm still having major problems on my machines (Ubuntu 10.04 with GTX460 cards). Up until about 5 days ago, things were running great, the cards were switching off with Einstein running 2 WU's simultaneously. Life was good. Now, despite detaching and re=attaching through BoincStats and doing anything else I can think of, I can't even get work units or the apps downloaded. The one machine that had a big backlog of v .50 WU's was unaffected but has now finished all of those WUs. It has been showing 3 WUs for nbodySim 0.21 for days in "downloading" status, but nothing has come through. Einstein is having a field day with all of the GPUs to itself. Is there anything that I can do from here to get things going again with MW? Thanks for the help. Regards, Steve |

If you checked the server status page, you will have noticed that there are no work units to download. Something is messed up with the server at this moment. |

Well, at least I won't be sending back bad WU's anymore due to computational errors. Hope it all gets sorted out.Judging from the various postings, it sounds like multiple unrelated problems. Regards, Steve |

I just switched back over to the Linux side and now have 14 tasks that exited with a compute error on the new 0.54 Linux OpenCL app. Could this be because of the recent incorrectly sized work that was sent out?

All my 0.52 (cuda_opencl) WU's end within one or at most some seconds with a computation error. My laptop uses a NVIDIA Geforce GT445M. What can be wrong? |

Other than the few WU that were too large and errored out, I seem to be running OpenCL WU on my 64 bit Linux 0.54 app successfully. Just looked at two WU, just reported and they validated. Maybe Matt needs to look at the build of the 0.52 Windows app and see if he missed something like the obvious goof he made on the Linux 0.52 app. Keith |

Ohh.. a pity, MW@h canceled the CUDA apps? Now OpenCL? AFAIK, at least 197.x nVIDIA driver needed. But, my machines need to stay with 190.38 which give the best performance @ S@h/stock CUDA23 app. I tested one MW@h WU with the new OpenCL app - immediately error. But, why got my machine with 190.38 the OpenCL app? It's not possible (via server) to send out the OpenCL app only to hosts with at least 197.x nVIDIA driver? If there are a lot of < 197.x driver hosts out there, wasted project server performance. DL/errors, DL/errors and DL/errors.. It's possible via app_info.xml to use the old (IIRC 0.24 CUDA23) app? Or this app don't work with the new WUs? BTW. In past I saw the german translation of this site. Since a few months only english. It's a mistake or wanted? |
