Message boards : Graphics cards (GPUs) : Why is there a work unit quota?
Author | Message |
---|---|
I had the system configured wrong so I received computational errors when attempting to crunch. I believe I have it set up correctly now, but the client won't give me any more work units because it says I have already reached my daily quota of 4 (quad core system). What is the rationale for limiting how much work people can do in a day? Will this limit be waived in the future? Why not let people crunch as much as they want? | |

I suppose it is because the project doesn't produce many workunits so they try to "spread" them as much as possible | |

...What is the rationale for limiting how much work people can do in a day? ... Because if there wouldn't be a limit people with misconfigured computers could produce hundrets or thousands computeational errors per day, which would slow down the whole projects because of resends. AFAIK every BOINC projects has a limit set. Some have a higher limit therefore you don't really see it, others have a lower limit... ____________ pixelicious.at - my little photoblog | |

The quota only applies if one is returning back to much error units. | |

Maybe because every singly WU on your computer errored out!? I saw in the stderr.out of your WUs that you use a 8800GTS, is that right? If so, your card is not compatible to the current app. Please have a look at this Thread in the FAQ to know why. ____________ pixelicious.at - my little photoblog | |

I don't think that this is the problem here, as there are three indicators of a compatible G92 chip :) | |

there really isn't need for more than the current amount of work, for most people here who can run this project have 1 graphics card and a dual or quad core computer. They then have 2 or 4 WUs, but can only run one at at time, so there is plenty of time to download another WU before running out. | |

There are 2 kinds of quotas. On is the limit for the amount of WUs one is allowed to cache. That's the limit set by the number of CPUs and the current minimum amount of work / maximum amount of GPUs you could possibly use. | |

I don't think that this is the problem here, as there are three indicators of a compatible G92 chip :) The project "banned" me for a day after I error. 4 task rule in action. I increased the core clock to from 602 to 704 MHZ and the memory from 1107 to 1258, giving a shader from 1296 to 1516. It computed to almost 70% without any problems and then it went whack! At 100% fan speed the core was at 63C. I'd be interested to know any success stories from any GTX280 overclocks in here! Otherwise, stock speed would suffice! | |

Indiana74 from our team has an overclocked GTX280, running at 684Mhz chip / 1458Mhz shader / 1296Mhz memory. Times are around 25100 seconds... | |

@Koschi: Indiana74 also gets some calculation errors.. not sure if I'd call this OC a success. | |

No, you don't have to request it. With every successful task you return to the project server, your daily quota will go up again... ____________ pixelicious.at - my little photoblog | |

What is the rationale for limiting how much work people can do in a day? Will this limit be waived in the future? Why not let people crunch as much as they want? The quota is adjusted automatically by the boinc server. The quota is to protect the project from hosts only returning errors. It limits the erred units until they are fixed so that these erred units do not quickly consume all the work needed by functional hosts. Too many errors returned on a work unit will cause it to not be processed any more. This causes problems for the project as it has to then reissue the work again. Too many hosts with errors could quickly consume all the work available, mark it all invalid and no-one would have work, thus slowing down the entire process making it a bad experience for everyone. The quota starts at a fixed number per cpu per day. If your host returns error, your quota is reduced. When your host begins to return valid results, your quota is raised. There are limits each project can set. To find your quota, go to the computers list under your account. click on one of the host id numbers. You will see somewhere on that page a line similar to this: Maximum daily WU quota per CPU 8/day The reason it is based on CPUs' is because before this project, there were only CPU's on BOINC. This is the way the BOINC developers (not the project) designed the system. | |

I have just installed 2 Nvidia GTX280 in my PC running under Vista 32 bits and, after doing all needed stuff (extend desktop, etc) I have gotten it to work properly. But I have a problem: | |

The number of WUs is limited by the number of cores of your CPU. If you own a Quad-core, you get 4 WUs at the time. At the moment the CUDA-supportet BOINC-version is experimental and in beta test. The only way top get more is at the moment to change the CPU to a Quad or Triple-core CPU. | |

Well, I have no intention to change my recently buyed Core 2 Duo, so I'll wait until BOINC allows to have more WUs downloaded at a time. In the meanwhile, it would be interesting for me to have only one GPU in GPUGRID, so I can have the other one crunching for FOLDING. My question is: | |
