Hi all! Just attached new host to the project (Debian Squeeze), it loading all the project's files but cannot process WUs: <core_client_version>6.10.17</core_client_version> <![CDATA[ <message> process exited with code 127 (0x7f, -129) </message> <stderr_txt> ../../projects/milkyway.cs.rpi.edu_milkyway/milkyway_0.21_x86_64-pc-linux-gnu__cuda23: error while loading shared libraries: libcudart.so.2: cannot open shared object file: No such file or directory </stderr_txt> ]]> I can't find a solvation here, in the Message boards, and instaed of using a shaman's technics I want to ask gurus how to make it work. If I need to make any symbolic links via ln then please explain me what exactly should I do. Previously on Xubuntu 9.10 x64 it started to work without any actions from my side. Thanks in advance! p.s. collatz is working on this host right after extracting an archive with application and corresponding files to the project's directory. |

Did you read the read-me file with the app? It should explain anything you need to do to the app. Doesn't expecting the unexpected make the unexpected the expected? If it makes sense, DON'T do it. |

Hm. Seeing into the /var/lib/boinc-client/ directory I can't find any readme. Remind that all project's files was downloaded automatically by BOINC Manager. |

Hm. Seeing into the /var/lib/boinc-client/ directory I can't find any readme. Oh, then you wouldn't have a readme in that nor will it run cuda. It is only a basic stock app. You need to download an opti app and install it yourself. Those will have a readme with them. *edit* looking for the site with cuda apps. |

Thanx, I'll try. It's strange that the stock application was working on Xubuntu a couple weeks ago... |

It won't run your cuda gpu though. (or atleast I don't think the stock linux runs gpu either) This thread might help; http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=584#9123. I can't find the cuda opti app only the ati app for linux. I know I am missing one site. |

Useless thread, unfortunately. I hope that someone of project developers will help... Resetting project was also useless. |

I'm running Ubuntu 9.04 on a C2Q host with a GTX265 (driver 190.18) and get the following error when I try to download a WU: Thu 03 Dec 2009 10:24:05 PM EST Milkyway@home Message from server: Can't use NVIDIA GPU app for MilkyWay@Home: NVIDIA driver version 19038 or later needed I'm assuming that the stock app is the only way to go since there doesn't seem to be an optimized app for CUDA at Arkayn's site. I don't see at the NVIDIA website where 190.38 is available for any Linux OS. What am I missing? |

I don't see at the NVIDIA website where 190.38 is available for any Linux OS Well, I only looked in the "CUDA Zone" at NVIDIA. Had I looked harder, I might have found these: http://www.nvidia.com/object/linux_display_amd64_190.42.html http://www.nvidia.com/object/linux_display_ia32_190.42.html Duh... <blushing with embarassment> |

The only thing I don't like is that BOINC Manager can't see an usable GPUs under my account - it need to be started via sudo /etc/init.d/boinc-client start to make it find a GPU... Earlier in Xubuntu there was a way to fix it - add boinc user to video group (usermod -a -G video boinc), but somewhy now it don't work..... Trying now to folow this advice from Gpugrid forums. Will see what happen. |

Well, everything is OK now - GPU is being recognized on system startup. There were applied two fixes (in my previous post and posted here. I don't know which of them is the main fix... :-) But it works. |

Do other CUDA applications experience the same behavior? Is the boinc user in the video group? |

Thanks for your reply. Do other CUDA applications experience the same behavior? No. I can play TrackMania Nations with 3D acceleration through wine without any problem. Collatz used to work fine on my host but lately it made my xorg dramatically freeze so I came to Milkyway to test it. Is the boinc user in the video group? No it wasn't. I added myself to the video group => same problem I added the root account to the video group => same problem These changes were done and the Boinc daemon was then stopped and restarted. Here are the messages in BoincManager: ven. 18 déc. 2009 14:26:27 CET Milkyway@home Starting de_s222_3s_best_1p_03r_43_5474221_1261046141_0 This is my cc_config in case something would be wrong: <cc_config> |

Is it acceptable to assume that it worked prior to v0.24? |
Send message Joined: 2 Apr 08 Posts: 10 Credit: 8,126,465 RAC: 0 |
Well, no idea since I missed Milkyway's first CUDA apps: I only tried with the current 0.24 version. I believe my system is OK since Collatz used to work without any problem until I began to get freezes with their new app, and this summer, I ran Aqua's CUDA app without any problem either. |
