Hello. I just recently started supporting SETI and notice a lot of issues with my client being able to download work (or communicate with the servers at all sometimes). Normally it would manifest in a strange manner in which a number of tasks would download in "bursts" instead of completing initially. Basically, the small amount of data transfer required wouldn't typically happen unless I manually forced the downloads to retry. At the moment, I can't seem to get very many tasks at all, and I'm stuck on a particular task that will not even download. Just to make this clear, this is only occurs with this project. So, suggestions? Edit: I sprawled the forums a bit and apparently I'm not alone. Are the project managers trying to work on this? |

This problem occurs when Astropulse work is being sent out which causes the download link to be badly overloaded. Cheers. |

... Wiggo's answer is basically true, though even before there was Astropulse work there were occasions when the 100 Mbps line was saturated. In 2007 for instance, the request for donations was accompanied by a budget which contained a line for the approximately $80000.00 they thought might possibly cover getting a 1 Gbps line. The Space Sciences Lab building where the project is located is about a mile from the main campus, with a major fault line to cross too. There were not enough donations, so we'll never know if the University would have approved it. More recently a 1 Gbps line was installed to the SSL, but for everybody there rather than S@H specifically. The web pages, forums, etc. go through that link, but the project has not yet been allowed to use it regularly for uploads, downloads, or Scheduler contacts. There are some sort of negotiations going on to get the needed permissions, and occasional mentions in the Technical News posts. Joe |

Actually, how much BW would be needed?? I can't see how much MB and ap data an hour that are floating through the cables. //TRuEQ TRuEQ & TuVaLu |

3 years of absence of the project and it nothing was improved in the Upload and download. The PC simply does not get enough WU to work generally. The stock is set on maximum. Maybe it is in Berkeley were already heard, shortly a Gauntlet takes place. But not with this performance. Wiki German Language, Wiki in deutscher Sprache View |

Actually, how much BW would be needed?? If AP's had their own 100MB line each then there would be almost no problem at all but if each had 200MB lines then reporting/uploading and requesting/downloading would be a snack plus be a good short term solution for a few years. Cheers. |

... Hmm, less then 2km away... Having 1 or 2 portable harddrives using a bicycle to exchange them to a seconc/third server there might work. //TRuEQ TRuEQ & TuVaLu |

... There is also a bit of hardware in the reach.com network or immediately after it that also has a problem which a good proxy will get around as many of us at times have found out but can not lock down. Cheers. |

Now I am downloading ap tasks with a speed 30-50Kb/sec which I very fast what I am used to. :) //TRuEQ TRuEQ & TuVaLu |

Now I am downloading ap tasks with a speed 30-50Kb/sec which I very fast what I am used to. :) The crickets didn't show a problem, but I think someone must have kicked something when he got in this morning. I just started connecting again after about 4.5 hours. (But I still get 'limit reached'; in progress is down to 645.)
