Posted 15 Apr 2020 by DeleteNull Does the wrapper work without BOINC? So I create a test dir and copy the files into it? And yes...you will get the source. |

Posted 15 Apr 2020 by DeleteNull A new (test) version of the wrapper (mfakto/mfaktc) is here: https://p-numbers.net/wrapper_26016_7.16_mfakt The next test can begin..... |

Posted 13 Apr 2020 by DeleteNull The old wrapper code is here Tomorrow (after work) I will try to implement a method in the wrapper that it can deal with the .ckp file. The ini file should change from CheckpointDelay=300 to CheckpointDelay=60. (both: NVidia and AMD) |

Posted 13 Apr 2020 by DeleteNull I added a second PC to this test, and it runs too (had to reset the project). The good news: Two tests are running, one with Ubuntu 18.04, the other with Opensuse 15.1. One with driver 20.10 (Radeon 5500XT), the other with driver 19.50 (R9 380) One will need about 10 hours, the other will need 27 hours. The bad news: You have to wait with 100% until it's finished, or you have to extend the wrapper. |

Posted 13 Apr 2020 by DeleteNull In this case the file M97983883.ckp keeps the checkpoint: 97983883 77 78 4620 mfakto 0.15pre6: 17 0 B624ABF0 97983883 77 78 4620 mfakto 0.15pre6: 45 0 150D244C 97983883 77 78 4620 mfakto 0.15pre6: 72 0 7071D1B7 97983883 77 78 4620 mfakto 0.15pre6: 93 0 48AC81E6 97983883 77 78 4620 mfakto 0.15pre6: 116 0 9EC681F1 So the estimated runtime is 9:50 hours. But the name M97983883.ckp is different for each test. ...we need a few additional lines of code in the wrapper, so that it can handle the .ckp file. |

Posted 13 Apr 2020 by DeleteNull No doesn't work: version `GLIBC_2.29' not found The PC where I took the wrapper from has a very new linux and this dependency is awful. I compiled BOINC on Ubuntu 18.04, and this wrapper should be o.k.: https://p-numbers.net/wrapper_26016 For Linux it's a hard way to deploy software..... |

Posted 13 Apr 2020 by DeleteNull You can download here: https://p-numbers.net/wrapper Version information: wolfgang@i920:~/Downloads/boinc-client_release-7-7.16/samples/wrapper> ./wrapper --version 11:22:17 (26004): wrapper (7.16.26016): starting 7.16.6 11:22:17 (26004): called boinc_finish(0) If you need a verion from trunk, I can compile it too. It shouldn't differ from this version here. |

Posted 13 Apr 2020 by DeleteNull Yes with elf-file. But in the tests before (zip without elf-file) was the same error. Standalone test with wrapper and job.xml succeeded. So I don't know what the problem is. Sofware is o.k., but if the wrapper is started inside BOINC it fails. |

Posted 13 Apr 2020 by DeleteNull I get an error (two): A new attached PC: Download error (checksum fail) Previously attached: The old ZIP (without elf-file) remains, if you replace the file manually the file is deleted (zip error). It seems you have to create a new version, sorry. |

Posted 13 Apr 2020 by DeleteNull All my "standalone tests" are okay too. I think the problem ist that mfakto-x86_64 starts a child process to compile the mfakto_Kernels.elf file. I seems that this forces the CHILD_FAILED error. Can you include this file: https://p-numbers.net/mfakto_Kernels.elf in the ZIP? (Just for a test) |

Posted 13 Apr 2020 by DeleteNull Thanks, now I get a new error: process exited with code 195 This is an error from BOINC (wrapper) 195 is CHILD_FAILED, Which means the wrapper failed to start the worker app. |

Posted 12 Apr 2020 by DeleteNull I have extended the parameter list for mfakto. (and compiled) You can download it frome here: https://p-numbers.net/mfakto_linux_x86_64_device.zip HTH the new code snippet: else if(!strcmp((char*)"--device", argv[i])) { if(i+1 >= argc) { printf("ERROR: no device number specified for option \"--device\"\n"); return ERR_PARAM; } else if (argv[i+1][0] == '0') // parse to 00 { devicenumber = strtol("00",&ptr,10); if(*ptr || errno || devicenumber != strtol("00",&ptr,10) ) { printf("ERROR: can't parse <device number> for option \"--device\"\n"); return ERR_PARAM; } } i++; }[/url] |
