Can anyone tell me why wu\'s I\'ve completed and was waiting on my wingnut to complete quorum (dropped the ball) was issued 2 resends and when they complete they both get credit and I get nodda? Just don\'t seem right. wu ID 4834991 4834992 A clear conscience is usually the sign of a bad memory |

For some reason the Wu\'s your not getting Credit for are marked Invalid ... I suspect it has something to do with your Wu being a v2.12 while the 2 other people that got Credit had v2.14 Wu\'s so the 2 Versions apparently clash with each other and somebody\'s out the Credit ... |

During the 2.12 > 2.13 > 2.14 `update` I recon quite a number of crunchers got this little `supprise` from cosmo, I lost fore WU to this changeover period, them being marked INVALID as well, its not a lot but a further irritation to cosmo`s latest batch of `interesting times`........ :( |

This has probably been raised before but I couldnt find anything. My current WU has been running for 54 hours (they usually take about 12). The progress bar rises to about 40% but then keeps falling back and resetting at about 3%. Will it complete? Should I trash it or let it run? |

The progress bar rises to about 40% but then keeps falling back and resetting at about 3%. Will it complete? Should I trash it or let it run? Two things to check before you throw it away: 1) Are you crunching for another project on the same machine and are they taking alternate periods of time (e.g. one hour on Cosmology one hour on other project(s)) 2) if the answer to 1 is yes check the setting in your general preferences on your account page here - the answer to \"leave application in memory when suspended?\" should be yes. If the answer is currently no go to edit preferences and change it to yes. If you use the home / work / school preferences you may have to change these instead / as well. Next wait a moment or two and in BOINC manager or BOINC View update the Cosmology project. I think this change only takes effect when BOINC has been restarted, so suspend all processing, shut down BOINC and restart it. When it comes up remember to resume processing. HTH Phoneman1 Edit : Just to add it probably only became a problem when the longer work units arrived 23rd July. |

How does \"leave application in memory when suspended?\" work when set to yes? Does it just leave the suspended application in the vitrual memory? I run a bunch of different projects on my machine and would be concerned about overloading the memory. |

I run a bunch of different projects on my machine and would be concerned about overloading the memory. Yes it uses virtual memory. See the BOINC Wiki (General Prefences section. If you click on Phoneman1 in the left frame here you\'ll see all the projects I have ever crunched for. About 90% of those were run at the same time on 1.8Mhz P3 with 1024Mb of memory. |

HTH Phoneman1 Edit : Just to add it probably only became a problem when the longer work units arrived 23rd July.[/quote] Thanks for the advice, I have now set to \"leave app in mem when suspended\". just a couple of thoughts/questions tho. 1 Does the same thing continue to happen when I turn my pc off or is the correct WU state saved in that situation? 2 Altho my credit total is pretty low, I have been crunching for a number of projects over a number of years and have never seen/noticed a similar problem with longer WUs. Surely any WU that will take more than a few minutes can be expected to be interupted. |

I run a bunch of different projects on my machine and would be concerned about overloading the memory. I\'m not sure how checkpointing would behave here. CAMB only gets round to doing a checkpoint when it feels its got something to write, which in my case can be around 30 mins. If I uncheck Leave app in memory when suspended will it do a checkpoint before quitting, or just lose the time back to the previous checkpoint I wonder? |

I have just noticed that the WU\'s progress has dropped back again even tho it hadn\'t stopped processing. Again, thanks for the advice, but its toast! |

If I uncheck Leave app in memory when suspended will it do a checkpoint before quitting, or just lose the time back to the previous checkpoint I wonder? ALL BOINC applications will simply lose whatever they have computed since the last checkpoint if you do not enable this setting. For some, this is of little consequence, since they checkpoint very often, but many projects only checkpoint after several minutes of computation, so you\'re losing those every single time you switch projects if it\'s not enabled. I\'ve had this setting enabled for... (looks when he first installed BOINC and does a few calcs) um... about 5 years now and it\'s never caused a problem that I know of on 18 different computers. Even though the \'Waiting to run\' applications are still using memory, the OS will move them to \'swap\' memory if another application needs to use the RAM on a more real-time basis. They take a couple seconds to move out of swap and back into real RAM when they start computing again, but that\'s almost always better than losing the computation time of simply stopping the process when switching projects. ![]() |

Yes and no. 5.6.x and later clients will try to wait for the next checkpoint before switching however they will only wait so long before switching anyway. If the client does not wait long enough then you loose all progress back to the previous checkpoint. BOINC WIKI ![]() ![]() BOINCing since 2002/12/8 |

Yes, I enabled checkpoint debugging, its interesting reading: 05:31:01|Cosmology@Home|[checkpoint_debug] result wu_072508_002234_1_0 checkpointed 06:55:47|Cosmology@Home|[checkpoint_debug] result wu_072508_002234_1_0 checkpointed 08:35:49|Cosmology@Home|[checkpoint_debug] result wu_072508_002234_1_0 checkpointed 08:42:06|Cosmology@Home|[checkpoint_debug] result wu_072508_002234_1_0 checkpointed At that rate if I was running another project along with C@H and switching every hour, C@H would just cycle around doing nothing for a week or so before it expires. |
