Edit - note that this appears to be a generic (non-optimised) application. I normally get allocated the PNI version for SSE3 CPUs. |

LHC@home Science :
Hide host info
(Message 27126)
Posted 8 Feb 2015 by Richard Haselgrove Post: I want to hide infos about my hosts running LHC@Home. What can I do? Although you are perfectly at liberty to hide your computer details, please pause and consider for a second before you do so. Look at Uffe's computers or my computers. You will see that very much less detail is shown, compared to what is available when you look at your own computer. That automatic removal of detail may be enough to satisfy your perfectly understandable desire for privacy. If at any point in the future you encounter difficulties running LHC, you are always welcome to ask for help (though the Number Crunching forum is the traditional place to do this). It greatly helps people trying to assist you if we can find your computers, and view details of the tasks you have processed - all of this is lost if you hide your computer entirely from other participants. |

Host messing up tons of results
(Message 27122)
Posted 1 Feb 2015 by Richard Haselgrove Post: Perhaps, because we've had so much work recently, those inconclusives hung around on the disk for longer than usual - the resends wait at the end of the queue behind all the submitted first-run work. It all contributes to the server and database load. |

Posted 29 Jan 2015 by Richard Haselgrove Post: And the ones I got back in return all seem to be short-running, so I'm already generating new uploads to fill up the new disk (or cluster filesystem quota, as I suspect it may be). I hope the CERN admins are in a position to keep an eye on it overnight. |

(Message 27095)
Posted 29 Jan 2015 by Richard Haselgrove Post: I fear that we may already have reached catch-22... Most of the work I've succeeded in uploading this morning has gone into 'pending', and is waiting for a wingmate to upload their work so it can validate and move on. And I've got 55 completed tasks backed up, waiting to upload so they can validate somebody else's work. But how can get the two queues ever to meet each other? |

Error reported by file upload server: Server is out of disk space !?
(Message 27091)
Posted 29 Jan 2015 by Richard Haselgrove Post: Uploads are stalling - possibly due to ore smaller files being returned and the server cant keep up in processing? Unfortunately, the files seem to be all the same size, whether the task runs for seconds or several hours. We just fill up the space much more quickly if a lot of short-running tasks are passing through the system. It probably helps (marginally) if we report any tasks which have successfully made it through the uploading stage, so that the next stage of processing can take place and the space can be freed up. The Einstein project had a problem with uploads - thing that was due to number of files. The problem at Einstein was that the server disk file system became incredibly slow - it was taking up to 8 seconds to locate a free 'inode' so that uploaded files could be stored and indexed. Given the thousands of files that a server needs to process, that slowed everything down to a crawl. |

Avast antivirus - false positive
(Message 27071)
Posted 21 Jan 2015 by Richard Haselgrove Post: One of my machines threw four errors this morning. Turned out that Avast had developed an aversion to 'sixtrack_win32_4517_pni.exe' overnight - an application which we've all been using perfectly happily since May last year, and which no other antivirus program finds any fault with. The problem shows as Exit status -185 (0xffffffffffffff47) ERR_RESULT_START It can be worked round by temporarily disabling Avast's shields while a new copy downloads, and by excluding the BOINC data directory from scanning (Settings - Active protection - File system shield - customise - exclusions, in my copy of Avast Free Antivirus 2015). This is now the third BOINC project which has suffered from a false positive detection by Avast since I installed this version for testing (the other two are Climate Prediction dot Net and GPUGrid) - in all cases, like this one, a detection on a perfectly good file which has already been in use for an extended period. I'll report it myself, but it's reaching the point where BOINC itself should make a protest. |

Sixtrack 32 bit vs 64 bit program for Windows
(Message 26917)
Posted 20 Oct 2014 by Richard Haselgrove Post: 'PNI' stands for Prescott New Instructions, and was Intel's trade name for what became SSE3 (http://en.wikipedia.org/wiki/SSE3). So the instruction sets are the same, and the same application has indeed been deployed twice so that BOINC's feature detection works correctly on both Intel and AMD CPUs. I don't know the thinking on why a separate 64-bit deployment was necessary too. |
