Posted 5 Aug 2020 by zombie67 [MM] Does it work yet, running one task per GPU, with multiple GPUs on Windows? Back in April, I think it was still being worked on. But I haven't heard any update since then. Got it. I will stay tuned for more info. |

AVX-512?
(Message 6561)
Posted 6 Jun 2020 by zombie67 [MM] I am not so sure. Here is the result of a machine with AVX-512s: Using zero-padded FMA3 FFT length 560K, Pass1=448, Pass2=1280, 5 threads, a = 3 FMA3 is not AVX-512. |

Posted 14 Apr 2020 by zombie67 [MM] Got it. Ah well, I was going to add more GPUs to help speed up the current run. Bot most of my machines are multi-GPU. So I can add only one GPU each machine. |

Posted 14 Apr 2020 by zombie67 [MM] Question: Does it work yet, running one task per GPU, with multiple GPUs? I looked at the FAQ, and I see conflicting messages. Specifically, I am asking about NVIDIA on linux, and NVIDIA on Windows. Running mfakto (opencl) |

Posted 3 Apr 2020 by zombie67 [MM] Can you try standalone with: FYI, mfakto did not exist. It was still inside a zip package. I had to manually unzip it, cd into the unzipped directory, and then run the commands. Here are the results. Notes: - I currently have the cc_config.xml set to ignore the internal AMD Radeon Pro 580 (GPU1), and run only on the external AMD Radeon VII (GPU0). - It looks like the first and third commands show the 580, and the second and fourth commands show the VII. - BOINC startup info: 5 4/2/2020 12:37:57 PM OpenCL: AMD/ATI GPU 0: AMD Radeon VII Compute Engine (driver version 1.2 (Jan 13 2020 20:12:46), device version OpenCL 1.2, 16368MB, 16368MB available, 8645 GFLOPS peak) 6 4/2/2020 12:37:57 PM OpenCL: AMD/ATI GPU 1 (ignored by config): AMD Radeon Pro 580 Compute Engine (driver version 1.2 (Jan 13 2020 20:12:40), device version OpenCL 1.2, 8192MB, 8192MB available, 3456 GFLOPS peak) kyoko:srbase.my-firewall.org_sr5 zombie67$ ./mfakto -d 00 -st |

Posted 29 Mar 2020 by zombie67 [MM] If the app_config is not working try this here: This is working for me. One GPU is running gpu72, the other GPU is running a task from another project. |

Posted 29 Mar 2020 by zombie67 [MM] <app_config> I am having trouble understanding what you mean with #2. I am already running two tasks, as I have two GPUs. But both tasks are running on just one of the GPUs*. What are you suggesting "c" should be, to get one task per GPU? It is currently set to "1", as it says in the FAQ. Note: BOINCmgr shows one task running on GPU0 and one task on GPU1, even though both tasks are actually running on just one of the GPUs. |

Posted 29 Mar 2020 by zombie67 [MM] With regard to the app_config.xml file, to run one pask per GPU: 1) I am getting the following error in the event log, when BOINC reads the app_config.xml file: Sun 29 Mar 2020 07:30:41 AM PDT | SRBase | Entry in app_config.xml for app 'GPU72', plan class '' doesn't match any app versions 2) Even with the error message, it seems to be working. I am running one task on each GPU, where it used to run both tasks on just one of the GPUs. If you want host details, it is this one. Edit: It was working for the first two tasks. But once they completed, and started new tasks, it went back to running both tasks on a single GPU. |

Posted 27 Mar 2020 by zombie67 [MM] I thought the linux apps were updated so that installation of the toolkit was no longer required. I could swear I read that somewhere. Or am I going crazy? |

Posted 1 Aug 2015 by zombie67 [MM] Agreed. Longer deadlines would solve the problem for everyone. Panic mode causes the BOINC client to do abnormal things. |

(Message 1729)
Posted 1 Aug 2015 by zombie67 [MM] That doesn't solve the problem. But I did find a work-around using the app_config.xml: <app_config> <project_max_concurrent>N</project_max_concurrent> </app_config> It constrains the number of CPU threads available to the project. Setting this to be number of threads minus the number of threads needed for the GPUs. |
