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] |

Posted 12 Apr 2020 by DeleteNull @Rebirther: I am sorry to read that. Tests with worktodo.txt: In the self compiled stuff: o.k. runtime about 8 min. In the unpacked ZIP: Failure. In the ZIP is contained: mfakto_Kernels.elf This will work only for the specific hardware and Linux for what this file was compiled for. This file has to be deleted ... it will be compiled during runtime in the target system. After deletion of mfakto_Kernels.elf the test is also running for the ZIP content. I have made my own app_info.xml.....but project doesn't accept this. |

Posted 12 Apr 2020 by DeleteNull Thanks. results are failing: 13:20:23 (13094): wrapper: running ./mfakto-x64 ( -d 11 --device 0) app_config.xml tells -d 11 but the argument --device 0 ist still there... How can we deal with this? |

Posted 12 Apr 2020 by DeleteNull I have managed to install the AMD 20.10 driver for linux and the Radeon 5500XT now passes the selftest without errors. Can you please allow new work for linux boxes with AMD GPU? |

Posted 11 Apr 2020 by DeleteNull Do you mean it's not recognized or it does not run? The device is recognized and calculation starts but fails. To test if this is a driver issue I have replaced the Radeon 5500XT with an R9 380 and now the selftest is completed with success. But now I can't get new work to test if "AMD with Linux x86_64" is running or not?! |

Posted 7 Apr 2020 by DeleteNull Just copy the file libcudart.so.10.1 into your /lib64 folder (or whatever your distribution needs) I followed the instructions in FAQ and found libcudart.so.10.1 in one of the folders. For all other PC's I copied libcudart.so.10.1 into the /lib64 folder and this works perferctly (for me). |

Posted 4 Apr 2020 by DeleteNull both works (not) for me. -d 00 seems to be the same as -d 11 GPU is listed and the test starts, but the selftest fails. GPU is a Radeon 5500 XT and mfakto doesn't like these new GPU's: Unknown GPU name, assuming GCN. All settings are wrong: AUTO, GCN, VLIW4, VLIW5, APU => selftest FAILED! |

Posted 29 Mar 2020 by DeleteNull mfakto runs on OpenCl devices. That can be AMD/ATI, NVidia, Intel and also some CPU. And RTX2070 is capable to run CUDA and OpenCL-Code |
