Sorry for the poor information giving. It only on my two nVidia machines. As soon as I dumped the config files and restarted with only one iteration of gpu work, everything returned to normal. I wonder if there is something wrong with the config file. This is the one I used..... The <gpu_usage>0.50</gpu_usage> tells BOINC that each task should use half of a GPU, thereby allowing 2 tasks per GPU. The <max_concurrent> is pretty much useless except in very limited situations. |

I think your problem is the "<max_concurrent>2</max_concurrent>". I believe that tells BOINC that only 2 total instances of all setiathome_v8 tasks can run, regardless of whether they're GPU or CPU. I'd recommend removing that line altogether. I think Jeff's got it. You're telling you want to run lots of WUs (ie all CPU cores & 2 on the GPU), then you're limiting it to 2 in total.

You might be pushing those processors a little hard IMO. Try backing off number of instances. If they then appear to work fine, then you need more feeding capacity. Wow! Never considered it would take that much cpu to keep the gpu happy. I guess maybe I should just leave well enough alone and run just one per gpu. I really appreciate all the help you guys toss out. I think I've learned more about the whole project in the last couple of months than I did in the first 10 years. Thanks again guys!! |

Wow! Never considered it would take that much cpu to keep the gpu happy. I'd suggest keeping the GT 730 with only 1 WU, any more will slow things down IMHO. The GTX 650Ti can handle 2 no problems, and will actually result in doing more work per hour than just running one. But you need to get rid of the max_concurrent; swapping the cards over between systems may also give some boost to output, particularly AP work. Grant Darwin NT |

I've never cared for putting that max concurrent right there. If what you mean by power issue is the power supply, nope, got plenty of wattage there. I guess I could swap the cards. I've been thinking of upgrading the MB and CPU in the Athlon anyway. Thanks!! |

Wow! Never considered it would take that much cpu to keep the gpu happy. Okay, I will first redo the app_config files and see what that gives me, not that I've got a clue as to what's going on.....thanks to all of you. |

Great news. I have two cpu cores running and two gpu cores running at the same time. I just deleted the lines you told me about and bingo....running great now.....holding breath...grin I'll try it on the other system in a bit, but I don't have much doubt that it will work fine. Thanks again!! |

Wow! Never considered it would take that much cpu to keep the gpu happy. Thanks, but that was probably my error when I tried to copy it to post here. Glad that you guys are really on the ball around here though. Sure makes it a breeze for us dim-wits. |

This is really interesting....at least to me....the 730 is using about 80-90 percent of the gpu and the 650 is using about 50-70 percent. I would have thought that they both would be nearly maxxed out. They both do bounce around a lot, but on average, that's about what they are using. I do realize that the 650ti has more cuda cores than the 730. |

I do realize that the 650ti has more cuda cores than the 730. The 730 is much older hardware, and the software is more optimised for it. The 650Ti is more recent & more powerful, but as the software hasn't been optimised specifically to take advantage of it, the load on it is much less. When you ran the Lunatics installer, what version of CUDA did you select for each card? From the Lunatics Windows Installer v0.44 thread, Rule of thumb selection guide: Cuda 2.3: PreFermi - NOT to be used on Fermi/Kepler/Maxwell Cuda 3.2: mixed systems Cuda 4.2: Fermi Cuda 5.0: Kepler/Maxwell EDIT- correction, looks like both the GT 730 & GTX 650Ti are Kepler class, just different variants. GK106 v GK208 They really don't make it easy to figure things out. Grant Darwin NT |

BTW, I see I have some ap's coming up and they are running on the 730. The config file has the gpu and the cpu usage both at .5, which is different than the non ap units at .5 on gpu and .04 on cpu. Will this be a problem when it goes to run the ap's? I noticed that they are opencl nvida 100 too. |

Allen, I see both your 730 and 650 have cuda 32/42/50 tasks, So just leave it alone for 24 hours and see what application BOINC settles in with and wants to run. |

Your task list is just showing you what the tasks were originally assigned when they were downloaded as "stock", before you switched to Lunatics. If you look at the Stderr for any that have run since you switched, you'll find they were run under "setiathome enhanced x41zi (baseline v8), Cuda 5.00", in other words, Cuda50, regardless of the original assignment. |

And set your cache to 0.5 days (there is no shortage of v8 work) It is much easier for testing if you don't have a pile of work you don't want. PS, you might want to consider shutting down a core on your AMD 5000, I know my AMD 4200 and 750Ti (Especially for AP). That would be: GPU 0.5 CPU 0.5 |

I guess I've just not spent enough time devouring all the technical information about the software side of SETI. I really appreciate all of you taking the time to explain the intricacies of the software. I guess I'm not as dumb as I had thought though, since I had surmised the possibility that the d/led wu's were d/led prior to installing Lunatics software. I really am grateful to Lunatics as well...they make it so damned easy to set up. |
