Yes, you are correct. Didn't think about what I was writing about being so used to using an app_config. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

Please use this comandline Thanks again, Mike! I tried your suggested commandline again and its working great! My BLC tasks are finishing in about 7 minutes (instead of 8 minutes with without your commandline) on both my RX470 and RX570. It's been running for a few hours now and everything looks good. |

I do want to point out that I'm getting a lot of invalid Astropulse v7 results (approximately 50%) on both CPU and ATI GPU. I'm not overclocking anything and temperatures are good. This has been ongoing, even before I entered the new commandline. The regular v8 8.00 CPU and 8.20 ATI GPU tasks are nearly 100% valid. |

i just upgraded and now have https://setiathome.berkeley.edu/show_host_detail.php?hostid=8656624 up and running. i have a feeling i can get a lot more out of this machine but have been very busy for the last few years with other things and have forgotten much i once knew. If anyone has any suggestions for tweaking for better performance i would be very happy to hear them. Intel i5 8600k CPU. NVidia GTX 680 card. Gigabyte Z370 XP SLI MoBo. Case with 5 fans plus a Noctua NH D14 CPU cooler. i thought i knew how to have the video card run ( at least ) 2 jobs at once but i seem to have stuffed that up.

Easiest way: look up app_config.xml and make one for yourself. Are you running stock SETI or the Lunatics version? ATM, I do not recall if it works on stock seti, you will have to check that out. (76, and counting...) |

With the current applications you would be best to avoid running two tasks on your GPU - it will struggle! Before diving into the "fun" of tuning allow time for BOINC to work out what the best application is - probably (but not certainly) it will choose either "SoG" or "CUDA50" - this can take a few days (or even weeks) as it has to work through the dross first - I see CUDA32 appears to have ben kicked out due to a high failure rate, there's nothing new there then.

You have a couple of choices. With the 680 and the CUDA50 app you could run two tasks on the card. The old CUDA apps were light on the cpu usage needed to support the gpu task. Or you could use the Lunatics installer to select the SoG application. Generally the SoG is the fastest app nowadays. But you might actually get higher RAC with the CUDA50 app at two tasks per card over the single task per card that the SoG is required to run. Both apps can be tuned with application settings but many more parameters are needed for the SoG app compared to the one or two parameters that the CUDA50 app allows. Read the readme for both apps in the /Docs directory in the Boinc directory for tuning suggestions.

running the Lunatics version . . When running the SoG app one at a time is not a requirement, but seems to be preferred by most people. I still run two at once on GTX950/1050/1060 cards and I believe Zalster runs 3 at a time on his beasties. If you have doubts about the behaviour of your 680 under the settings you have chosen I suggest you d/l a copy of Afterburner, the monitoring section is great. I can see at a glance how any changes I make affect the way the cards run. I find it a handy tuning tool. I find too that twosies give me about a 10% plus improvement with SoG. Stephen . . |

Yes, you can run doubles but not with the most aggressive tuning. Which negates the best RAC output for the most part. Whenever Raistmer the app's developer recommends singles, I go with what he recommends. And Zalster doesn't run Seti on SoG anymore. The two hosts he left running here are the special app on Linux. Most of his iron works for GPUGrid now. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

I should probably keep more up to date on what other users are doing but there are so many :) Stephen ? ? |

GPUGrid does high-performance all-atom biomolecular simulations from their About snippet. "Doc" Zalster has an obvious interest in the projects goals. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

OK, his interest is good, but I still have no idea of what they do ... :) I guess I would need to do some serious reading. (Is it perhaps concerned with studying disease behaviours?) Stephen ? ? |

You can just read the main page intro for the project. Looking for new drug possibilities, modeling diseases and such. Pretty much common to all the biomedical research distributed computing projects that require a supercomputer to crunch physical interactions in real-time.

That sounds like a worthwhile successor project if they ever pull the plug on SETI. Stephen :) |

Hello Stephen: Earlier today i downloaded and installed Afterburner. After installing i looked at tasks and rather than seeing Running (0.24 CPU's + 1 NVIDIA GPU ) i saw Running (0.24 CPU's GPU missing ) i uninstalled Afterburner, rebooted. Back to normal. Did i stuff up somewhere ? Is there a way i can see how much work is being crunched by my GPU vs the CPU ? i have 16 GB RAM installed, any thoughts on how much performance adding another 16GB would add ? i can have up to 64GB on this machine. Because the universe is just too big for us to be alone in. |

Is there a way i can see how much work is being crunched by my GPU vs the CPU ? Just checking the processing times lets you know how things are going. Running 1 WU with aggressive settings would improve it's output, although the system responsiveness may be seriously affected. Tweaking the values used can improve the responsiveness, while not affecting output too much. i have 16 GB RAM installed, any thoughts on how much performance adding Zero. Seti on the CPU doesn't use much RAM- if the system isn't doing anything else, even 4GB is plenty. Grant Darwin NT |

Hello Stephen: . . I doubt if Afterburner caused that issue but it may have contributed to it. I have had the same thing happen on this machine sometimes after a reboot, so maybe Afterburner is introducing some sort of delay but I think it may be the version of BOINC. On my other rig with a much older version of BOINC it never happens. The solution is quite simple, shut down BOINC and BOINC client, count to 10 or 15 if you count fast (the thousand and ... count does the job) then restart. It then always comes up OK. Is there a way i can see how much work is being crunched by my GPU vs the CPU ? . . 8GB is enough to run BOINC and the apps to crunch happily, 16GB is more than enough. If you purely want stats then 'BOINC Tasks' will collect them for you. A lot of ppl swear by it ... Afterburner is about monitoring the moment by moment performance of your hardware to be sure you have your settings right. . . I hope that answers your questions. Stephen :) |

Im in need of some help. I was an idiot and made a post before i even saw this thread. Heres a link to the post i made. https://setiathome.berkeley.edu/forum_thread.php?id=83880 |

I have to ask, did your actually load the drivers for it or is Windows just running the stock VGA driver for it? Cheers. |
