Message 53047 Posted 16 Feb 2026 by [TA]Assimilator1 |
In reply to Crystal Pellet's message of 14 Feb 2026:In reply to [TA]Assimilator1's message of 14 Feb 2026: Thanks :), I see this for one task I have running :- PYTHIA Warning in StringFragmentation::fragmentToJunction: bad convergence junction rest frame PYTHIA Warning in JunctionSplitting::SplitJunPairs: parallel junction state not allowed. PYTHIA Warning in JunctionSplitting::CheckColours: Not possible to split junctions; making new colours PYTHIA Warning in JunctionSplitting::CheckColours: Made a gluon colour singlet; redoing colours PYTHIA Error in StringFragmentation::fragment: stuck in joining PYTHIA Error in Pythia::next: hadronLevel failed; try again PYTHIA Error in MiniStringFragmentation::fragment: no 1- or 2-body state found above mass threshold PYTHIA Warning in SimpleSpaceShower::pT2nextQCD: weight above unity 100 events processed PYTHIA Error in SimpleSpaceShower::pT2nearThreshold: stuck in loop PYTHIA Warning in SimpleSpaceShower::pT2nextQCD: small daughter PDF 200 events processed PYTHIA Error in StringFragmentation::fragmentToJunction: caught in junction flavour loop 300 events processed 400 events processed 500 events processed PYTHIA Warning in StringFragmentation::finalRegion: random axis needed to break tie 600 events processed 700 events processed PYTHIA Warning in MiniStringFragmentation::ministring2two: random axis needed to break tie 800 events processed 900 events processed ends :- Pythia::next(): 19000 events have been generated 19000 events processed 19100 events processed 19200 events processed 19300 events processed 19400 events processed 19500 events processed 19600 events processed I assume it's still running then? Is there anywhere in that file that shows progress point? Are the warnings anything to worry about? |

Yea I've had loads that have appeared to be stuck at 100% and I aborted quite a few too! Would've been useful if the LHC guys had sent us a BOINC message warning about the long runtimes and the inaccuracy of the BOINC % for VM tasks, would've saved wasted crunching time :(. My 'show graphics' button is greyed out, any idea why? |

about a dozen WUs are showing "Postponed: VM Environment needed to be cleaned up", now firstly that message is talking past tense, so is it sorted now or is that just bad English and it should say ..."needs to be cleaned up". Apologies for a very late reply (I forgot about this and gave up on LHC VM apps) & and thank you for your reply. I've no idea what a PR is, but I take it you've long since taken the fame! :D Well spotted on my typo, I make many, but usually spot them just after I've posted, so BOINC forums extremely limited edit time occasionally thwarts that ;) Re concurrent tasks, I would've just let BOINC do it's thing, if only 1 task could (can?) be run at a time, I wouldn't know how to limit BOINC like that. Nor would I have known (or know) how to do this "- Use VirtualBox Manager and VirtualBox Medium Manager to remove orphaned "disks" and VM definitions." I don't recall BOINC giving me those 3 instructions from a core message, beyond its "Postponed: VM Environment needed to be cleaned up" Re the forum's 1st rule :- Our message boards are moderated. Posts are subject to the following rules: Posts must be 'kid friendly': they may not contain content that is obscene, hate-related, sexually explicit or suggestive. I've no idea what you are talking about here, my post was kid friendly, not in the slightest obscene nor did it have any of the last 3 misdemeanours. The most you can say is that I was slightly rude by calling the app 'rubbish', perhaps you could say I breached the last point in rule 5, but that was my opinion and I said it in a very mild way. Anyway, it's been ~2.5 yrs since these posts, Have these issues been resolved now? Or does VM LHC still require micro-managing/setting up? |

LHC@Home is not a plug and play project like other BOINC-Projects are. After forgetting why I stopped running LHC last year, I ran it again and quickly ran into problems, not wanting to go through that mammoth post (and spend hours following the dozens of steps!) about how to get VM working properly I tried the 2nd option as above, choosing Theory sim (as it seems to have the most WUs). But even sticking with that, and when I had 100% cpu time set, I still ran into problems :(, about a dozen WUs are showing "Postponed: VM Environment needed to be cleaned up", now firstly that message is talking past tense, so is it sorted now or is that just bad English and it should say ..."needs to be cleaned up". I thinking perhaps the later because multiple WUs are showing that message, also another 6 WUs are showing the message "Postponed: b" ,and no I haven't typo'd that's all they say :p. So why am I getting those messages even though I'm only running Theory sim exclusively? Also, LHC is causing bad system lag, even though I have loads of spare RAM available. What's that about? Additionally, some WUs are showing ETAs of 10 days! What's that about? (although I don't think any are actually taking that long). Main rig specs in sig. I really like the LHC@home projects ideas and the research it's doing for LHC, one of the projects I'm most interested in, but this rubbish VM app is just making it a nightmare and I'm not going to bother if it's going to take hours to fix. I thought I could just run Sixtrack again, but that project seems to often run out of WUs. PS, Yeti, your user of the day :) |

I don't recall seeing that on the front page. Anyway, disabling Atlas seems to have done the trick, no problems caused by LHC running now, but I currently have 14 errored WUs, 13 are for CMS sim, no idea why (exit codes mean nothing to me). Common ones are :- 207 (0x000000CF) EXIT_NO_SUB_TASKS 194 (0x000000C2) EXIT_ABORTED_BY_CLIENT And a single 1 (0x00000001) Unknown error code Also the estimated times for some Theory sim WUs are 8-9 days! Lol. But they aren't actually taking that long. |

Ah yea, you got it, now unticked, thanks :) |

Message 44587 Posted 28 Mar 2021 by [TA]Assimilator1 |
As per title I disabled the ATLAS apps, I did this because it was taking more CPU resources than was set by BOINC! And now, after a few weeks strangely, it's downloading ATLAS WUs again! Wth?? Anyone know what's going on? (and yes I have re-confirmed they are still disabled). For now, I've shut off new WUs completely. Hoping someone can help, as I would like to continue to contribute to LHC. |

Just thought of a better answer, rather than not run LHC altogether (I want to run it!), I've disabled the Atlas app. Let's see how the other apps behave.... |

Well this takes the biscuit, I'd set BOINC to 85% computing time to leave some CPU power for GPU folding. Last night and this morning I found my system had ground to a crawl and LHC VM was taking 100% CPU time! So I restricted BOINC to 50% and now LHC is 'only' taking ~70%. What with BOINCs messed up way of trying to balance credit, and now LHC hogging resources I'm done with it :( But why was it taking 100% when I'd set 85%!? It should of left any spare threads for Rosetta, not try and run another 8 with LHC VM. (that's with Atlas WUs) |

But I now have a WU stuck at 100% and 1.5 days elapsed time! |

In the short to medium term I would've just quit running LHC if I needed to go through all that. Anyway, some team mates managed to help me - https://forums.anandtech.com/threads/weekly-dc-stats-28feb2021.2591268/post-40454305 Turns out AMD-V was disabled in the bios, and it was called SVM mode, hence I didn't spot it in the manual or bios. Since enabling it, I've had no errors. |

Thanks for your reply, that's a very large post of yours you linked, is their a particular part I can get away with reading? I don't want to spend hours on this. |

Thanks for your reply. Never heard of it, what is it? I don't recall seeing that in the bios, and I don't see it mentioned in the manual... |

I'm getting a ton of errors atm, I had a quick look at the task details, but it doesn't mean much to me. I've got no errors in Rosetta atm, for what it's worth. Can anyone help? |

Yep switched my main cruncher over to R@H & F@H some weeks ago, good to hear LHC pitching in too :) |

What's the latest on this Eric? (I've not monitored results in a while, & just caught up with this thread) Ah good to hear 1 of them replied! :) When I said 1 of them, I was referring to a user with major host problems, as per this thread. I never said they weren't part of the project, btw most of us are in different teams ;) :P. |

Other CPU intensive tasks shouldn't cause any errors. |

Setting a weeks worth of work is too long really, as you discovered when you got more 8hr WUs. I usually set a cache of 3-4 days. The only way I know to see how long a WU is going to take is to look at the time 'remaining' in the tasks list. So no you can't 'cherry pick' the longer WUs. And yea LHC often runs out of WUs, that's normal ;), which is why I have it running alongside other projects. |
