this host has huge ratio of errors and non-empty results http://lhcathomeclassic.cern.ch/sixtrack/results.php?hostid=10301941 and this http://lhcathomeclassic.cern.ch/sixtrack/results.php?hostid=10339565 this one is rated high in inconclusives http://lhcathomeclassic.cern.ch/sixtrack/results.php?hostid=10137504 |

I upgraded mother board, raid drives, and CPU still with windows 8.1 Pro (64 bits) and had only one problem of system shutdown when CPU overheated. Intel´s furnished cooler could not handle the 186 watts. Went to water, no more problems. Last weekend went to Windows 10 Enterprise (64 bit)build 9926 but upgrading to 1041 or 1046 this weekend. Have set no more tasks to down load. Seems that every other task is giving me the invalid or inconclusive tasks, even with CPU not over clocked. Watch message board, but see nothing on Windows 10 issues. My other projects are not generating any errors at all. HELP please. Bill in Brazil William C Wilson São Paulo Brazil |

Seems that every other task is giving me the invalid or inconclusive tasks, even with CPU not over clocked. Bill I'd propose you to run BOINC in Compatibilty modes and play with 32 and 64-bit versions compatibility Win7,8 , Vista etc and see output. Also in properties set "Always Run as Administrator" make sure your BIOS is latest and no fancy settings about CPU and memory there. Finally play with CPU settings in BOINC and LHC project |

Thanks; I have e-mailed the user. In fact all errors seem to be DISK_LIMIT_EXCEEDED. Still, not good for him nor us. Eric. |

Thanks Bill; this could be really interesting and useful. Fast machine, Windows 10, ...... I am now watching closely all your Wus and trying to determine the cause of the Invalid. Shame it takes so much CPU time but there you are. Eric. |

Eric so users do crunch x86 on their 64-bit PC right? isn't it possible incompatibility point? |

Eric I run SixTrack and other 32-bit BOINC project applications on 64-bit Windows 7 with no problem at all. If anyone is having problems with their SysWOW64 environment, it's specific to their computer, not general or widespread (Windows 10 - as yet unreleased - is another question entirely, of course). 32-bit Linux apps on a 64-bit system are more of a problem, because many projects rely on 32-bit compatibility libraries and not every user installs them. But that results in an immediate application crash, not the sort of pseudo-valid results that Eric is wrestling with. |

It could be, but all my tests work and there is no consistent failure. Still there might be something on perhaps very new machines. Once I have cleared all the "noise" I'll get back to the basic problem of genuine result differences. I have one CERN customer (maybe two) who have different Validated results for the same task! Bill seems to be suffering from a real problem too. I don't feel I can publish my work until these are resolved. (I shall be on vacation from 14th to 28th April and this will be a great chance to investigate in real detail :-) Just want to leave the service in good shape and the customers and clients happy. Eric. |

Also my executables are all statically linked, though there could still be other compatibility issues. I think Microsoft are very strong on backwards compatibility; many many users/owners run 32-bit apps. I am trying to keep an open mind and analyse the evidence. Remember we are sill talking about very few differences among millions of tasks. Seems to be getting worse though. Eric. |

DISK_LIMIT_EXCEEDED. Apropos of nothing really, I had a bunch of LHC and SETI stop with this error yesterday, but I was running my first CMS-dev job which had also crashed... |

DISK_LIMIT_EXCEEDED. Yes CMS-dev is what caused that to happen. Volunteer Mad Scientist For Life |

Hello, my machine (id: 10327477) has started to get some invalids. Is it normal? |
Send message Joined: 29 Nov 13 Posts: 59 Credit: 4,012,100 RAC: 0 |
I only see 3 you have as invalid, 2 of those were also invalid for other hosts, looks like those were dodgy WUs. The 3rd maybe down to your machine, but I wouldn't worry about just 1, just keep an eye on your tasks page to make sure they don't grow in number. Btw why have you cancelled so many WUs? Host linked as someone seems to of forgotten to do that ;) http://lhcathomeclassic.cern.ch/sixtrack/results.php?hostid=10327477 Team AnandTech - WCG, Uni@H, F@H, MW@H, Ast@H, LHC@H, R@H, CPDN, E@H.

About cancelled WUs... Because I have often got network issues with my repeater and "flash"-tasks (that terminate in few seconds) could leave my machine without work. I edited my ncpus from cc_config to get about ~150 WUs and to ensure workload for an entire week, but I got too many ~8h tasks that weren't finishing on time. |

to get about ~150 WUs and to ensure workload for an entire week why would you need that many? if router fails you will see it in day or two, not a week I guess? If units failed due to timeout you put other users job in waste bin as they lost their already executed tasks due to your timeout I think. Admins, correct me if it's not like that. |
