I've got an E6600, no CUDA, Seti only & run with a 4 day cache. I've got about 24 hours work left on the system & am getting the "limit on tasks in progess" message whenever it requests new work. Grant Darwin NT |

When seeing the message of task limit, how many tasks are currently in the queue? What is the threshold? For what it's worth, the 20 limit for this PC has been confirmed. It finished the WU and sent it, requested work and got 1 more. Further requests yield the message. I have a 10 day cache set and this is a Core 2 Duo 3Ghz machine. WUs generally complete in under 2 hours. In my opinion, the calculation is either way messed up or they have set a limit of stored WUs independent of performance calculation. |

There's definately some truth in the thought that there is a limit of 20 tasks. Luckily - or not depending on how you look at it i had 23 tasks remaining and was receiving the limit message, as soon as there were 19 it downloaded 1 task ....rinse cycle repeat 3 times now. Whatever decides the limit it cannot be hardware performance i've just beefed the rig up to 3 x 480 and have a 10 day cache set, i am only hoping this may be a temporary thing to ease the innevitable strain on the servers today.....and we'll all wake up tommorrow with 10 day cache's ;-)) |

confirmed here too. I got exactly 20 tasks. Janice |

Then I can set SETI to NNT for whole 1-2 days and forget about any work for my ATI card... Too many CPU tasks onboard... |

20 on the machine I'm watching now, too. Report 1, get 1. Report 3, get 3. I sure hope this is temporary as three day server shutdowns will leave me looking for something else to crunch, or cool the machine as it sits idle. |

This could be a mechanism that insures that everyone receives a little work at the beginning of the download cycle. It is not necessary to completely fill the cache in the first 2 or 3 hours. We have all weekend to fill the caches again. Boinc....Boinc....Boinc....Boinc.... |

Primegrid does that on their challenges perhaps we are seeing that on seti now. I'm betting the limits will ease off as we hit the weekend. everyone will have their uploads done and they can start pumping out more work In a rich man's house there is no place to spit but his face.

We have all weekend to fill the caches again. This makes sense to me, and for me, I prefer this method as long as it eventually increases prior to the next outage. I hated waiting for potentially days to get work after an outage. |

We have all weekend to fill the caches again. Matt said this yesterday Programming wise, Jeff was able to tackle some longstanding datarecorder issues. You may have noticed our results-to-send queue has been growing rather large - these are some test tapes Jeff's been splitting which will be sent out rather quickly once the floodgates openMaybe these are the test work units he was talking about.

We have all weekend to fill the caches again. Or maybe We've hit the Limiter? Someone might know, Or We wait until after Midnight(PDT) to see if any downloads happen. :D Uploads went well, I only had two instances of HTTP errors, Not bad at all. :) The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

We have all weekend to fill the caches again. But then why not come with a message that can be understood?? btw I DID get 2 new tasks 3-4 hours ago (even though I have more than 20 WUs in cache) but since then only been getting the limit message. |

Like I already mentioned in one of the other threads.. MilkyWay@home have a limit of 12 tasks in progress. If BOINC ask for more, BOINC get: Message from server: No work sent Message from server: (reached limit of 12 tasks in progress) Because of the SETI@home server say not the max limit, I guess something is wrong here. |

As can be seen below, upload a completed task, get one in return. 7/2/2010 2:22:53 PM SETI@home Sending scheduler request: To fetch work. 7/2/2010 2:22:53 PM SETI@home Requesting new tasks for GPU 7/2/2010 2:22:54 PM SETI@home Scheduler request completed: got 0 new tasks 7/2/2010 2:22:54 PM SETI@home Message from server: No work sent 7/2/2010 2:22:54 PM SETI@home Message from server: This computer has reached a limit on tasks in progress 7/2/2010 2:22:55 PM SETI@home Started upload of 02mr07ah.11033.7843.15.10.247_3_0 7/2/2010 2:22:58 PM SETI@home Finished upload of 02mr07ah.11033.7843.15.10.247_3_0 7/2/2010 2:23:10 PM SETI@home Sending scheduler request: To report completed tasks. 7/2/2010 2:23:10 PM SETI@home Reporting 1 completed tasks, requesting new tasks for CPU and GPU 7/2/2010 2:23:12 PM SETI@home Scheduler request completed: got 1 new tasks I suspect that this limit will increase as time goes on and the downloads will be more liberal.

After the 3 day maintenance, my BOINC got 2 GPU WUs. ~ 15:55 UTC. Every ~ 10 mins UL/report of a result. But since 15:55 UTC no new DL. If the limit of 20 tasks in progress per host, how we could use the ReSchedule tool? :-| Usage of VLARkill CUDA app? -> damaged quota, backlog -> not ask for new work. :-| SETI@home have always new surprises for us. :o) |

Argh! I wish. I uploaded and reported 1200 tasks four hours ago and haven't gotten one single download.. 800,000 tasks and none for me. Edit: I see the problem after reading below. I still have 194 GPU tasks and 24 CPU tasks. Guess I won't get more work until they get down to 20 tasks.. |

Network traffic has dropped right off & there is plenty of work ready to send, so i guess almost everyone has finally hit the task limit. Grant Darwin NT |

Network traffic may have dropped off, but the master server is still taking a pretty good beating. It really would have been nice to know what their plans are on this. Janice |

It does seem so. :) Hopefully this will now even out a slow spread of cache limited work units to everyone. :) Off-topic, where in Darwin are you bro? Maybe you should message me privately, i'm in Rapid Creek. :) - Jarryd |
