Posted 29 Jul 2021 by Dunx Post: Radeon VII 8x WU average 11 seconds each, sadly sits idle waiting for Wu's for too long.... R9 280x - HD 7970 average 42 seconds. D.C. |

Posted 29 Jul 2021 by Dunx Post: Please run this code on a Radeon VII.... But mine sits idle waiting for WU's anyway, so why bother ? Seriously, if it will keep my PC running 100% of the time then YES do it ! D.C. |

Posted 17 May 2021 by Dunx Post: Welcome Back ! My poor PC isn't keeping me warm without it's GPU wattage ! Glad you are on top of the situation, it's always worse when the academic side of operations is down. Back in the 90's we had it easy ! Nobody was really "hacking" the mini-computers the college here had. Looking forward to some more Work Units soon ! Regards, D.C. ( Wakefield, U.K. ) |

Ideal number of concurrent tasks.

Posted 7 May 2021 by Dunx Post: Thanks, for the info guys.... I was of the opinion that multiple clients wouldn't be allowed. The project sends 900 tasks which process in about 10 seconds each, then it sits for 15 minutes to pass, before sending more. At my desk I can poke it into action quite easily, but all day whilst at work it's on autopilot. Must investigate further ! Regards, Dunx |

Posted 26 Mar 2021 by Dunx Post: I'm running 8x on my Radeon VII but the real problem.... is the "Project" is not willing to keep it fed with work 24/7 ! I should sell it to some Bitcoin nut-job and scalp the hell out of them.... Grumpy old man, dunx |

Run Multiple WU's on Your GPU
(Message 70341)
Posted 12 Jan 2021 by Dunx Post: You need to build a tired old PC and add a few HD 7970 or R9 280X cards to it.... Just because Nvidia sell you a high priced item doesn't make it suitable for efficient use on this project. I bought a used Gen 1 GTX Titan Black for the high DP and extra RAM, but it is still 3x slower than a cheap R9 280X. I currently run a Radeon VII and spews out a result every 11 seconds, running multiple tasks on a quad core CPU. I would say Nvidia cards would be better used for GPUGrid, but they have no work available.... dunx |

Multiple GPU Problem
(Message 69988)
Posted 12 Jul 2020 by Dunx Post: I run six WU at once for an average time to completion of 10 seconds per WU.... eight is as fast, but my PC can't keep up with the multiple GPUs. The machine is limited to only four cores/eight threads, and the GTX 970 needs some CPU time too ! I now have an X79 system with a six core/12 thread CPU to play with, but it doesn't like my memory, so having to manually step through all the DRAM variables. dunx |

Posted 12 Feb 2017 by Dunx Post: Windows 7 Ultimate 64 bit - BOINC 7.6.33 - GPU Driver 14.1 Xeon E3 1270 V3 @ 3.7 GHz HT on MW 1 task only - GPU @ 1065MHz - Memory @ 1555MHz 40 seconds - NO CPU tasks ! Same with CPU tasks limited to 88% - 43 seconds dunx P.S. Tried two tasks per GPU, and it messed up all four GPUs.... liking the sensible VRM temps though ! |

Posted 18 Jul 2015 by Dunx Post: Theoretical yes. But windows throws around the Threads at random. I don't know any option or program that can reserve one Module. I use process lasso on my Intel i7 - W7 system, don't know if it can help you here ? dunx |

Posted 15 Mar 2015 by Dunx Post: I have two R9 280X cards and my error rate is similar to yours Tex.... I'm running two WU's per card and Cosmology on the free CPU cores. dunx P.S. Much as I dislike the waste of resources, it's a %age I'm able to tolerate.... P.P.S. NOT using X-Fire as ( like you I'm not a gamer ! ) - wonder if actually using X-Fire with two cards might work better overall ? ? ? |

Posted 7 Feb 2015 by Dunx Post: Hmmmmm. Magically I now have tens of minutes of WU to crunch (vs 1-2 minutes). Perhaps the Weiss IS listening in? Try :- <max_file_xfers>N</max_file_xfers> Maximum number of simultaneous file transfers (default 8). <max_file_xfers_per_project>N</max_file_xfers_per_project> Maximum number of simultaneous file transfers per project (default 2). dunx P.S. Not sure I've found the right options TBH.... |

Posted 4 Jan 2015 by Dunx Post: I get better results using 0.5 cpus per 0.5 gpus.... 32 per WU two at a time HD 5870 dunx P.S. @ 88% CPU utillisation - too leave a spare "core" for the GPUs.... |

Posted 4 Jan 2015 by Dunx Post: I found I needed 0.5 cpus per 0.5 GPUs to maintain a decent workload. Dropped CPU to 88% in BOINC manager. At 100% each WU took 50% longer to process. HTH dunx |

Tesla K40 & System Upgrade Thoughts?
(Message 61447)
Posted 29 Mar 2014 by Dunx Post: I would suggest that managing a system with two or more cards is made easier by mixing ATI/AMD with Nvidia GPU's, you can mix and run many projects, but a pair of cards can be set up as an SLI/X-fire pair. Each brand have their strengths on different projects, but I find managing them is easier. IMHO ( P6T7 WS + HD7900 + HD5800 + GTX 480 currently adding water cooling bit-by-bit...) dunx P.S. If that is an i7 4770 it has an i-GPU which can be used with the Intel OpenCL SDK - I'm running E@H on mine... |
