Posted 13 Sep 2008 by MSeery Post: Same problem here. This is my first LHC@Home unit so I don\\\'t have any \\\"it worked before\\\" to benchmark against. As I\\\'m writing this the work unit has been at 100% for 1hr 20mins and does not seem to be using any CPU usage on the WindowsXP task manager. However nor is it completing the task and other BOINC projects are waiting for it to finish. Are you using a 6.2.x client? A number of people have had this problem with the version 6 clients. The answer seems to be to downgrade back to 5.10.45. Hope this helps Michael |

Number crunching :
Actual LHC data to crunch?
(Message 20291)
Posted 12 Sep 2008 by MSeery Post: So essentially what MSeery is saying is that this project is entirely useless and will never get work. That is not what I\'m saying. The original question was about if we would be helping with analysing the data produced by the LHC, which we won\'t be. This project is about helping the scientists with the configurations for the beam, which in my opinion is an important and worthwhile function. There is also ongoing work being created for this. They are also looking at bring other physics projects into LHC@Home which hopefully will extend the usefulness of this project. Hope this helps clarify matters. Michael |

BOINC 5.10.x??
(Message 20277)
Posted 12 Sep 2008 by MSeery Post: I'm a bit confused here. I upgraded to 6.2.18 since I was having some vista issues with 5.x, and as we speak it seems to be happily churning on LHC WU's (I've even completed a few and gotten credits for them). What exactly is the problem with 6.2.x? Some people have been having problems as reported here. If 6.2.x is working okay for you, then I wouldn't worry about it. Hope this helps Michael |

Posted 11 Sep 2008 by MSeery Post: Today I joined LHCatHOME . But I\\\'m getting following error. There is a problem with the server at the moment, which is why you are getting the message. It will be solved when Alex or Neasan (the project administrators) fix it basically. They are based in London, so the working day starts about now, so I would have thought within the next few hours (unless they are at CERN for the switch on). Michael |

Actual LHC data to crunch?
(Message 20101)
Posted 10 Sep 2008 by MSeery Post: When, if ever, will LHC@home be crunching actual LHC data in WUs? In short, we won\'t be. The actual messages are over several threads, one is here. Snippets for a quick read are below Not a chance, a single dataset which a machine needs would be at least 1 gigabyte of data and your machine would have to download that before it could do anything else. We are TRYING to find something from the analysis of real data that will port but the big four have told us that the code is too, lets say, verbose. and We have a second project it\'s called the Grid. The LHC\'s computing needs are being fulfilled by that IF we can get something ported to BOINC we will but I reiterate we have no money. Also it\'s not just the download are you all willing to have large, hard drives, massive broadband connections and run only Scientific Linux (CERN edition) and not use your machines for anything else? and However this would require a person to port the software from the current Grid setup to BOINC and for the Grid software to be actually portable. Not only do we not have this person (see the money issue above) we have also been told that there is no way the applications the Grid runs are lightweight enough to be ported to BOINC. We keep prodding and asking about simulation applications/other experiments etc but nothing so far. Hope this helps Michael |

Posted 9 Sep 2008 by MSeery Post: Hey, The workunits are actually in progress, meaning that they have been sent to a computer, but have not yet been returned. To see if work is available to be sent to your PC, you need to check the top line, which currently states Out of work. Michael |

Posted 5 Sep 2008 by MSeery Post: Hi, Yes this is normal. The very short workunits are ones where the parameters make the beam unstable and it crashes into the LHC. Michael |

(Message 19945)
Posted 16 Aug 2008 by MSeery Post: If I set LHC at a low priority, when there Your other project will run at 100%. Also, does this affect how much work I get? To a degree. BOINC will try to ensure that each project gets the time that it should for the resource share assigned to it. If a project has a lower resource share than it gets less time, therefore less work. It is a bit more complicated with LHC, as time is almost always owed to LHC from other projects as the work is intermittent. Lastly is it 10 per user or 10 per computer? It is 10 per CPU core as I understand it. Hope this helps. Michael |

(Message 19736)
Posted 24 Jun 2008 by MSeery Post: I understand there's still no or little work, right? Correct. As the turn-up of the LHC is imminent now, are there any plans to use the help of the LHC@Home Community for doing the real science on LHC? No. As previously posted by the admin (these quotes have been snipped, but you get the general idea). We have a second project it's called the Grid. The LHC's computing needs are being fulfilled by that IF we can get something ported to BOINC we will but I reiterate we have no money. Also it's not just the download are you all willing to have large, hard drives, massive broadband connections and run only Scientific Linux (CERN edition) and not use your machines for anything else? and However this would require a person to port the software from the current Grid setup to BOINC and for the Grid software to be actually portable.

(Message 19676)
Posted 26 May 2008 by MSeery Post: Why are work units and results disappearing? Workunits are removed from the master database when all five results are returned. This ensures that the database remains as small as possible so that performance doesn't suffer. The results are still available to the project scientists. Hope this helps Michael |

Posted 15 Apr 2008 by MSeery Post: I want to reinstall LHC@home (after I lost everything due to a lightning strike), but the BOINC Manager "attach to a new project" button requires me to enter an "account key" You can have the account key sent to the email address you signed up with from this page http://lhcathome.cern.ch/lhcathome/get_passwd.php It also sounds like you have an older client. The current client only requires an email address and a password to sign up to a project that you already have a account at. You can download the latest client from here http://boinc.berkeley.edu/download.php Hope this helps Michael |

Posted 18 Dec 2007 by MSeery Post: The results I've had a quick look at appear normal, all your fellow crunchers returned them with a very short run time as well. This is normally caused by the magnet configuration being simulated being unstable and the beam failing as a result. Hope this helps Michael |
