Hello, Please anybody who is involved in development of the CPDN Application, have a look at Result-ID 5110074. The story: yesterday I upgraded my kernel, and wanted to give the binary nvidia driver another try. I wanted to check, whether I could view the Graphics of CPDN. Just after I hit the \"Show Graphics\" button in boincmgr the Graphics showed up for about half a second, disappeared and an \"Computation error\" occured in just after that. After that i recognized, that the module failed to install, which might have caused the error. But IMHO showing the Graphics should not influence computation in such a way. All those preciuos CPU-cycles :( Please have a look at that Result and see the error message. And please keep me informed ;) Thanks for your interest. Greetings SC PS: If there is any info missing in this post please let me know. I\'ll see if I can get it ;) |

The last set of messages suggest that BOINC caused the crash: scan: boinc_ufs_cpdnout1.zip But there were errors in several palces before this, staring with: scan: boinc_ufs_cpdnout1.zip And this is yet another example of why \'the old hands\' have been saying for ages: Make backups! |

The file conversion shouldn\'t result in a client error. Most likely it was the display initialization. Which isn\'t really done by the cpdn app. Could you please provide detail of your graphics card. |

The last set of messages suggest that BOINC caused the crash: Hi, Thanks for the reply. So now there is a backup solution in place ;). Once a day there will be an update from now on. I am using backup-manager for that, and before starting the update the boinc client is stopped, the home-partition for the boinc client is then remounted readonly after waiting for 180 seconds (as I don\'t know yet how to tell when the app is really finished after requesting the shutdown). Please tell: Does the boinc client wait until the running app is definitely shutdown, or does it forward the request for shutdown and than immediately shuts down itself? Maybe a stupid question, but I want to do it right this time ;) . . . And sorry for wasting that much work. Some questions though: What happens to WU\'s that finished with a client error. Are they ever being retransmitted to another client? Or are they gone and never computed again? It would be a pity if important data was never collected, because of a users fault. |

The file conversion shouldn\'t result in a client error. Hi, my graphics card is a GeForce3Ti200 AGP with 64MB of RAM. But I want to add, that I was fiddeling around with my xorg.conf to find out, how to get the binary nvidia-driver to work again. I later recognized, that the nvidia module wasn\'t loaded but the nv-driver for X provided by Xorg. I had all config-parameters set up to start the nvidia module, but actually I forgot to change the name of the Display driver module to \"nvidia\" in the \"Device\"-Section of the xorg.conf. So the \"normal\" nv-module was loaded with a set of parameters tweaked according to nvidia\'s README: Section \"Module\" Load \"bitmap\" Load \"dbe\" Load \"ddc\" #Load \"dri\" #Load \"GLCore\" Load \"evdev\" Load \"extmod\" Load \"freetype\" Load \"glx\" Load \"int10\" Load \"record\" Load \"type1\" Load \"v4l\" Load \"vbe\" EndSection . . . Section \"Device\" Identifier \"Nvidia GeForce3 Ti 200\" Driver \"nv\" VideoRam 65536 EndSection At least I think the config looked like that, as the one I used for testing wasn\'t backed up too :/ Maybe that will help too. |

Failed wu\'s are marked for re-issue up to 4 times. However, they may or may not be used again; there are millions of combinations to try. |
