Another thing about DCF, as Richard found out, there is a safety factor built in, if the DCF goes too low, then it restricts d/loads. While it may be true that 0.02 can't be represented exactly, you are forgetting the other side of the coin. Both sides of the equation will be off by the same amount when you try to compare the constant "0.02" with someones DCF of "0.02". So they will be equal. |

Richard I am posting this only to report my experience with my GPU (only) processing. After I used the process you described of resetting the project, the DCF reset to 1.00 but then dropped from 1.00 to 0.017663 in approximately 10 hours. I looked at the "In Progress" count on my page for "Valid Tasks for Dave Lewis" maybe 10 times today during that 10 hour period and at no time did I have more than 150 WU's "In Progress." The WU's I received were overwhelmingly shorties. As expected, as soon as the DCF dropped below 0.020 all new WU's stopped flowing. I was surprised how quickly the DCF dropped. Last night I modified the app_info.xml file and this morning I am seeing just under 400 WU's in the cache for my GPU. After making the config file change the DCF was around 2.3 and overnight it has dropped to 1.015. I will be removing the addition of <flops> to the app_info.xml file when the problem is fixed because the cache size is still smaller than I prefer. Thanks for your suggestion. It didn't work as well as I hoped but it worked a whole lot better than what I had been experiencing. |

OK....what NOW? My top rig is down to 233 total tasks, of which 32 are AP on the CPU. And I am getting the limit of tasks in progress message??? Meowgrrrrrrrrrrrrrrrr. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

Yes, I've had to re-apply the treatment myself. In my case, my GTX 470 does work for GPUGrid as well, so I'm not in the slightest concerned if the SETI queue is temporarily dry - it has something else to do. Since I was down to a single task, and downloads seem to be flowing reasonably freely today, I thought I'd try the true 'one click' test (although I did make a copy of my last WU's datafile, just in case). Clicking 'Reset project', as expected, deleted the WU and set DCF to 1.0000 It also wiped out the communications deferral, and started a new work fetch almost immediately. Even though I was, in theory, "too soon" after the previous request, the WU I'd just abandoned was re-sent with no delay, and subsequent work fetches got additional, new, work. So, the quick'n'dirty approach can buy you a bit of crunching time, though as you say not a lot. My card burns through shorties in around 90 seconds, or forty per hour. Using that rule-of thumb that DCF will fall too low again after 200 - 300 tasks, that would be 5 - 7 hours, which is roughly what you experienced. The advantage is that it avoids the somewhat delicate operation of editing config files, and can be applied while BOINC is still running. |

well the DCF is fluctuating a bit but not really getting above 0.2*** . Task duration correction factor 0.242121 Hopefully this will get all worked out eventually. I am running climateprediction.net also now and It only runs on CPU ( I think ) I will still try to run GPU on seti@home , and Just not worry about it... will try to get it set up in seti prefs to do GPU only right now . work on seti is hit or miss anyway , so untill it gets fixed , might as well as do some good for somebody ... Not leaving s@h just using resourses as effecienty as i can... Crunch away ! |

'Reset project' is the nearest thing I can think of to a one-click solution just at the moment - everything else involves manual editing of files. But it can't be used if you have multiple applications, and only one of them has run out of work - but in that case, your DCF wouldn't have got down as low as 0.01, so I assume it doesn't apply here. when you say applications , do you mean like Cuda and CPU work , or like 2 differend projects , like seti and milkyway ? |

OK....what NOW? When I got home this morning I was out of GPU WU's, I lowered the number of tasks per card and rescheduled a few "spare" VLAR's over from CPU. Not enough WU's available to keep the faster machines happy. Kevin |

OK... Need help. Math is my sore spot. Flops for dummies......real dummies. Don't know an 08efffp from a kitty phhhhhhht. How do I try flops for my top rig? And this pisses me off to no end, cuz I shouldn't have to be mucking about with it in the first place if the server code were fixed. And rather a pita when you have 8 rigs running. But I gotta try something. Thanks. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

OK... Yes, most certainly it is not our problem...and yet the result of it is. The kitties need more kibble. So, I have asked for help with flops. Snarling all the way. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

Ok... I have a few questions about this debt between projects thingie ! Since Seti :-( , is almost Not doing anything ( much ). I started running another project , It is running about 500 % more than seti , :-( . so how does this project debt work ? Will it cause the second project to stall , when a certain point is reached ? This isn't hijacking this thread , because the reason is no cache for seti and Only getting a couple wu's at a time about 3 times as long as it needs to be... |

It's your thread, my friend. You may hijack it any which way you please. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

Well...... I'll be out for the evening. The kitties will have to play with their DCFs and flops and scratch up whatever WUs they can sniff out on the Seti servers. They just meowed at me.... What's that, kitties? Translating from feline to human can be a bit tricky, but I think they said.... "More work from Berk, please." "Freedom is just Chaos, with better lighting." Alan Dean Foster |

Will it cause the second project to stall when a certain point is reached ? Not at a certain point (of debt amassment) but when SETI@home is providing your host(s) with enough work again. Then the SETI@home tasks will take precedence. Gruß, Gundolf |

Will it cause the second project to stall when a certain point is reached ? Thanks GruB how do you check the amount of debt ? these WU's from climatepredictions.net are HUGE WU's They run about 21 days long... 580 (approx) hours , CPU at this time... I'm trying to run GPU WU's for seti , but you know how that is working out right now ! That should cause a HUGE debt , unless seti gets fired up again pretty soon , and starts working like it should... |

Thanks GruB Name's Gundolf ;-) how do you check the amount of debt ? In the Projects tab, you can right click the projects and request a properties display. There might even be a button, but I can't tell for sure, since I'm still running BOINC 5.x. Greatings, Gundolf |

It's the bottom one in the 'Commands' group, that's the top group on the Projects tab. There are two sorts of debt: 'Short term' - which is used to choose which task to run next. This is known as "scheduling priority" on the property page. 'Long term' - which is used to choose which project to request work from next. This is known as "work fetch priority" on the property page. |

I must be thick headed... I noticed that about work fetch Priority in properties , I guess i was just looking for the word debt in it somewhere... Sigh... Thanks Richard and Gundolf... :-) ( and sorry about the name mistake ) :-) |
