(Message 10423)
Posted 14 Jan 2025 by DeleteNull I cannot recommend to uninstall "FPGA Emulation Platform for OpenCL" from Intel (https://www.intel.com/content/www/us/en/docs/opencl-sdk/developer-guide/2020-2/intel-fpga-emulation-platform-for-opencl-getting.html) because that will disable other things installed on this computer. But it seems that mfakto software is confused if more than one OpenCL device is available. |

Posted 12 Jan 2025 by DeleteNull It seems you have installed FPGA Emulation This is the message from one of your failed WU: OpenCL device info name Intel(R) FPGA Emulation Device (Intel(R) Corporation) device (driver) version OpenCL 1.2 (2023.16.12.0.12_195853.xmain-hotfix) FPGA Emulation will not work with the software mfakto. |

Posted 27 Apr 2024 by DeleteNull You can use a PCI-E extender, so that the GPU have "more air" between them. |

Posted 7 Feb 2024 by DeleteNull Are you sure Boinc is in the right order? I see it give a random order compared to say MSI Afterburner. I had a machine with 6 cards in it, and Boinc's order compared to MSI was something like 3, 5, 1, 2, 0, 4. I assumed it was physical connection order vs. driver loading order. Although Folding@Home is different again. Very annoying when trying to allocate cards or work out which is overheating. Yes in my case with "only" two GPU BOINC has the right order. The GPU where the boot screen appears is GPU0 and the other (dark) one is GPU1. The same order as the BIOS allocates the screens. |

Posted 7 Feb 2024 by DeleteNull Just made a test for two AMD GPU in a windows host. 5500XT and 6500XT. The wrapper works well, device 0 has this message: 2024-02-07 13:34:18 (8960): wrapper (7.24.26018): starting 2024-02-07 13:34:18 (8960): wrapper: running mfakto.exe (-d 0) 2024-02-07 13:34:18 (8960): wrapper: created child process 2012 mfakto 0.15pre7-MGW (64bit build) device 1 has this message: 2024-02-07 13:34:19 (6484): wrapper (7.24.26018): starting 2024-02-07 13:34:19 (6484): wrapper: running mfakto.exe (-d 1) 2024-02-07 13:34:19 (6484): wrapper: created child process 5128 mfakto 0.15pre7-MGW (64bit build) What does mfakto do? device 0: OpenCL device info name gfx1034 (Advanced Micro Devices, Inc.) device (driver) version OpenCL 2.0 AMD-APP (3592.0) (3592.0 (PAL,LC)) gfx1034 => 6500XT device1: OpenCL device info name gfx1012:xnack- (Advanced Micro Devices, Inc.) device (driver) version OpenCL 2.0 AMD-APP (3592.0) (3592.0 (PAL,LC)) gfx1012 => 5500XT This is a bit confusing because BOINC tells this: 07.02.2024 13:32:57 | | OpenCL: AMD/ATI GPU 0: Radeon RX 5500 XT (driver version 3592.0 (PAL,LC), device version OpenCL 2.0 AMD-APP (3592.0), 8176MB, 8176MB available, 4891 GFLOPS peak) 07.02.2024 13:32:57 | | OpenCL: AMD/ATI GPU 1: AMD Radeon RX6500 XT (driver version 3592.0 (PAL,LC), device version OpenCL 2.0 AMD-APP (3592.0), 4080MB, 4080MB available, 5499 GFLOPS peak) So this is the opposite assignement to that was mfakto does. The calculation in fact is done only with one GPU: the 5500XT (e.g. GPU-Z) So there seems a bug in mfakto, not in the wrapper. It is not a driver issue, PrimeGrid uses both GPU in parallel. |

Question/Problem with Intel GPU work units
(Message 9662)
Posted 6 Feb 2024 by DeleteNull The main problem is this (mfactc.c): GPU_type gpu_types[]={ {GPU_AUTO, 0, "AUTO"}, {GPU_VLIW4, 64, "VLIW4"}, {GPU_VLIW5, 80, "VLIW5"}, {GPU_GCN, 64, "GCN"}, {GPU_GCN2, 64, "GCN2"}, {GPU_GCN3, 64, "GCN3"}, {GPU_GCN4, 64, "GCN4"}, {GPU_GCN5, 64, "GCN5"}, {GPU_GCNF, 64, "GCNF"}, {GPU_RDNA, 64, "RDNA"}, {GPU_APU, 80, "APU"}, {GPU_CPU, 1, "CPU"}, {GPU_NVIDIA, 8, "NVIDIA"}, {GPU_INTEL, 1, "INTEL"}, {GPU_UNKNOWN, 0, "UNKNOWN"} }; Depending on different values for the integer in {GPU_INTEL, 1, "INTEL"}, you will get different results for the number of successful and "not successfull" self tests. But will never get it to 0 of not successful? |

(Message 8638)
Posted 7 Jan 2023 by DeleteNull As far as I know: BOINC passes e.g. "-device 1" to the device so may be we have to update the code that it understands -device instead of -d. |

Posted 30 Dec 2022 by DeleteNull Hello, you have to copy the needed libs into your library folder (for me /lib64). then create a link: e.g.: lrwxrwxrwx 1 root root 21 29.

Posted 22 Nov 2020 by DeleteNull Depending on the flavour of Linux you are using you have to choose the right directory. For Ubuntu (and derivatives) it is /usr/lib and in OpenSuse it is /usr/lib64. But there are some other Linux Distros to confuse the user ;) |
