Posted 22 May 2020 by ![]() Post: There are lots of tasks due to time out in the next 48 hours, including quite a few from the 8+ week turnaround "1337" Ryzen. I see that it now has less than 20k tasks in progress. It seems to be returning tasks a couple of hours before the deadline in order to get lots of 3rd 4th or 5th places. https://setiathome.berkeley.edu/results.php?hostid=8652081&offset=60&show_names=0&state=4&appid= The final tasks in progress have deadlines of 25 July or later, although I think there will probably be only a few thousand left by then. Results out in the field is now below 250k, about 24 hours later than I expected. The curve seems to be flattening at the moment, but I think it will get a bit steeper when a lot of timeouts from the last few days of Original Replication arrive in the next few days. |

Can anyone remember the name of it? I cannot think of it for the life of me I think this http://wuprop.boinc-af.org/results/delai.py is it. |

Posted 20 May 2020 by ![]() Post: While I was looking at the history of exoplanet discovery, I found this article https://blogs.scientificamerican.com/observations/who-really-discovered-the-first-exoplanet/ In 1979, Gordon Walker and a few colleagues at the University of British Columbia began searching for planets. He was the world’s preeminent authority in precise Doppler observations. He designed his survey on the premise that all planetary systems resemble the Solar System. The biggest signals—and, given the limitations of his equipment, the only signals he had any chance of detecting—would come from giant planets, similar to Jupiter, which takes 12 years to go around the sun. Which meant that Walker needed to commit to a very long-term project. That sounds familiar to some of the hostility towards SETI research in the past |

Posted 20 May 2020 by ![]() Post: 21 years ago, there were almost no known exoplanets. However the first exoplanet discovery may have occurred but not been recognised in 1917 https://www.jpl.nasa.gov/news/news.php?feature=6991 In the last 21 years a lot has changed https://exoplanets.nasa.gov/alien-worlds/historic-timeline/ SETI@home is refining and focusing the search, and hopefully we will resume in a few years by looking in the more likely places. |

Posted 18 May 2020 by ![]() Post: 8 of the top 20 by RAC still have a significant number of tasks In Progress. From a few hundred, up to over 20k. I did look for Any WU's that still need Validation, I didn't find any. The host with over 20k tasks should have a lot less by the 23rd of May, including about 6 of my last 15 WU's |

Posted 18 May 2020 by ![]() Post: I've just looked through around 2500 Tasks assigned to one of the top computers by RAC There are a lot that have deadlines in the next 5-6 days, and another big block around 14-15 June However, I was looking for any tasks with deadlines beyond 23 July, I found 3 or 4 for 25 July, but nothing beyond that. So the last Workunits will Probably be finished before the end of July, but there might be a very small group in August |

Posted 18 May 2020 by ![]() Post: Given that the lab is closed, and all the desktop computers off, it is highly unlikely that Eric has been able to run through the outstanding tasks. He may have done a few from home, but nowhere near enough to clear the pool. The most probable explanation is people actually running the tasks or aborting them, thus allowing work units for which the canonical result has been declared to clear from sight. Remember that once the canonical result has been declared our part in the science for that work unit is done, extra completed tasks for that work unit are ignored, but as far as I can see credit is awarded where applicable. I would have thought that one or more of the servers could easily crunch 800 tasks in a few hours. You could be right, it depends how soon they want to start working on the next stage of Nebula with the "complete set". The notice at the top of the front page seems to indicate that all the canonical results are done. That message appeared about a week ago. I also noticed that it promotes Science United, so I suspect that DA posted that message :) |

Posted 18 May 2020 by ![]() Post: I suspect that Eric may have run the last few hundred on local machines in the lab if they wanted to get the last few Results into the database. I looked at the top 20 hosts a few days ago, None of them still have any Pendings or Inconclusives left. There are still tasks In Progress going up to the last week of July, but some of the Workunits have up to 6 Tasks, and every one that I have looked at is already Validated https://setiathome.berkeley.edu/results.php?hostid=8191899&offset=0&show_names=0&state=1&appid= is an example of a few 3 month deadline WU's, there are probably a few others out there. [Edit] I just noticed that there could still be WU's In Progress one month before my personal 21st anniversary. I wonder if there will still be any at the end of August :) |

Posted 13 May 2020 by ![]() Post: I think the majority of the ghost units, have now been completed and validated by one of the duplicate replications, however there are probably still some, possibly many, Ghosts in progress It probably won't be worthwhile doing any personal ghost recovery, because most of those units have been Validated, and are not needed. A few days ago, the number of Workunits still awaiting results was about 0.12% so there might be about 650 still needed, but the project staff might have processed the last few locally by now I wonder if anyone still has any Pendings or Inconclusives left ? I just looked through the top 20 hosts by RAC and there are 0 Pendings and 0 Inconclusives between any of them ! 4 of the top 20 by RAC still have several thousand tasks In Progress, another 4 or 5 just have a few hundred each, I'm guessing that Most of them are probably Ghosts, because they have been in contact with the servers in the last 24 hours. |

Boinc Credit - Cobbles, New, Screws, and Another New Idea?
(Message 2048897)
Posted 12 May 2020 by ![]() Post: I think the current situation at SETI is fairly exceptional, most projects don't usually send out 6 tasks when they only need 2 results. The deadlines should have been cut to 7 or 14 days at the end of March, or earlier. If a project were to routinely send out more tasks than needed for quorum, they should enable code to reduce Unnecessary waste of time or effort. Some projects need rapid turnaround, while others can usually wait a few weeks or months for the results. They can't really change the rules after the tasks have already been sent. |

Posted 12 May 2020 by ![]() Post: I think it would be 2 or 3 scripts, one of which has been done before I'm not an expert on the BOINC server code, but I think it is basically switching an option on or off, then updating. The load on the servers now is probably low enough to turn on the options that were previously off due to excessive load. |

Posted 11 May 2020 by ![]() Post: Aborting tasks now could case "Too Many errors" state. If Eric wants the last few results quickly, he could probably make sure that all the Ghosts are re-sent if needed, and then Cancel Unstarted Tasks. That would probably be more effective. |
