Wow.. After days of trying to get APs and only getting one or two a day.. I go to sleep and wake up to find a task list full of them. 2010-12-16 07:50:54|SETI@home|Scheduler request succeeded: got 1 new tasks 2010-12-16 11:11:15|SETI@home|Scheduler request succeeded: got 15 new tasks 2010-12-16 11:33:12|SETI@home|Scheduler request succeeded: got 2 new tasks 2010-12-16 12:04:46|SETI@home|Scheduler request succeeded: got 2 new tasks 2010-12-16 12:25:53|SETI@home|Scheduler request succeeded: got 6 new tasks I really need about 15 more, but due to some issue that can't be found/resolved at the moment, occasionally an AP will run 8-16 hours longer than normal. If I save that WU and run it in stand-alone mode, 23-25 hours like normal. So right now my DCF is off by about 10 hours.

All of which goes to prove that Ned Ludd knew what he was talking about when he said that the download bandwidth needed to be more intelligently managed. I agree that 85% of available bandwidth would be better than 95%+, but looking at Scarecrow's Graphs the slope for Work in Progress in steeper this week than last. So as bad as thing are when maxed out, it's better for feeding the demand than only using 60% or so of the available bandwidth. Grant Darwin NT |

I think the point may be proved that its maxxed out bandwidth that causes ghosts. All my machines have had at least 40 resends in the last few hours. First time I've had (potential) ghosts since the project came back up. As I type this all are in "Project Backoff" with some units showing as much as 20 minutes elapsed. T.A. |

"Work in progress" is not the same thing as feeding the demand. One of my machines currently has 9 tasks ready to run, but 248 "in progress" but still trying to download. Ghosts are also counted in "work in progress", remember. |

One of my machines currently has 9 tasks ready to run, but 248 "in progress" but still trying to download. In the four hours since I posted that, the score for that machine is: Crunched 9, downloaded 0. Still 248 waiting to download. GPUGrid gets another timeslice ;-) |

just did a quick check on 1 box that is not downloading wus at the moment ... 571 wus waiting to be crunched 618 wus alledgedly in progress according to seti ghosts 47 |

When I look at mine, I have 80 wu on my machine with SETI reporting 7 valid, 57 pending, and 2 in error. That totals 146 which is what SETI says I have. I don't think I have any ghosts at the moment unless I am counting something in the total I shouldn't, but it sure would be a coincidence if that was the case. |

I am not terribly worried: I've got 4 AP units that BOINC thinks will take 200 hours (experience tells me 18 - 20 hours is more accurate). If you let run opt. project apps, you have added <flops> to your app_info.xml file? |

Right now I have 167 cuda's and 2 MB's downloading to one machine. It is running at about 22kpbs x 4 WU's at a time. Seems to be doing pretty good on my end. Traveling through space at ~67,000mph! |

MB download is very fast but astropulses takes forever. With each crime and every kindness we birth our future. |

That is because of the size of the download for AP tasks. "Time is simply the mechanism that keeps everything from happening all at once." |

No its because of the badwith. On MB task i have 30 K/s On AP only 1 - 3 K/s. With each crime and every kindness we birth our future. |

From what I have seen on my machine is I'm not limited per download but per computer how fast I can download. Last night I was getting work units at 22kbps on one WU but 10 on another etc. I seem to stay, combined, around 35-40kbps while downloading. Is there a limit placed on the speed from Seti or is this a bottlenecking issue? I've never paid attention to my speeds on download until here lately. Traveling through space at ~67,000mph! |

When the pipe isn't saturated, I would be able to download MBs in ~1 second, so 300-400k/sec. I would have expected that when there is still 50mbit of unused throughput on the pipe, I could use all 18mbit of my download speed for APs. Unfortunately, my observation on this is that it will only run between 50-200k/sec for AP downloads. I'm not complaining at all, but there does seem to be some kind of throttling somewhere. It takes between 60-180 seconds for each AP to download for me, but it isn't my hardware, because at any time, I can go download java from oracle's website and get 2.2MB/sec.

Unfortunately, my observation on this is that it will only run between 50-200k/sec for AP downloads. Yeah there is throttling indeed. Tonight I'm getting about 60kbps on my 30Mbit line. Should be getting much higher speeds, but your download speed will also be affected by your routing to the server etc. If there is congestion other places along the way it slows things down. However they are throttled on their end, and if they weren't you would possibly be getting worse speeds as everyone ate up everything! Not sure how accurate their cricket graphs are but the highest I've ever seen it was about 97mbps, so kind of makes you wonder what QoS they do have running. Right now it's only at 79Mbps!
