Posted 30 Oct 2019 by bronco Post: How do you assign credits?this is a question that no one could ever answer. I have brought up this topic a few times, and with the exception of rather dumm replies from a certain member there was never ever a logic explanation. Actually the replies given were very logical to anybody with average intelligence and a little understanding of how computers work. Apparently they were too complicated for certain dumm members who think bitching and whining about things they refuse to understand can make the impossible become possible. |

Posted 21 Sep 2019 by bronco Post: You don't seem to understand that explanation or perhaps you just don't like it so I won't bother repeating it because chances are you still won't buy it.thanks for your nice and friendly reply, anyway. Was very helpful :-( Your attempt at sarcasm is noted. The irony is that my reply is actually the very reply you need to hear, think about and take to heart which makes it friendly even if you don't like it. The reasons for illogical credit awards have been explained several times but it seems you just brush them aside in your never ending mission to be the sqeeaky wheel who motivates the devs (BOINC and LHC) to solve the crazy credits problem. But there is no good solution and devs (BOINC and LHC) know it. Accept that fact and squeak instead about a problem that does have a solution. |

Posted 12 Sep 2019 by bronco Post: This is the point The credits are nonsense the second they are awarded. What does it matter If they degrade and become even more nonsensical later? The only purpose they serve is to give bored people something to discuss. The more ridiculous credits become the more there is to discuss. |

Actually the server will send your Linux box the native Sixtrack app automatically if Sixtrack is selected in your prefs. To run Linux native Theory and ATLAS follow the somewhat tidy procedures given in other threads here and of course select "native" in project prefs. |

Posted 5 Sep 2019 by bronco Post: From what I gather, theory is Linux specific. Anything else to keep in mind on that front - is VB still required for Linux, too? You can use VB on Linux if you want to but it's not recommended. It works well enough (some say) but it's very inefficient. LHC@home has 3 native apps for Linux: Theory, Sixtrack and ATLAS. Since they are native they don't require VB (which can be a real PITA sometimes) but the best part is the much more efficient use of memory and other precious system resources. (BTW... I'm not plugging Linux as a more efficient OS. The same efficiencies could be achieved with native Win apps but unfortunately only Sixtrack has a native Win app, there is no native Theory or ATLAS app for Win. ) My linux box is completely headless so not sure how to go about grabbing the latest vb and extension pack using ssh as I'm still a Linux newbie... If you can use ssh, cut and paste command lines into a Linux terminal and edit a few config files (as su (superuser)) then you can easily install the 3 Linux native apps following the somewhat tidy procedures given in other threads here. Well worth the effort, imho. |

Posted 20 Jul 2019 by bronco Post: Really hard to keep sitting on your hands. Well done, bronco !! Not so hard with assistance from my watchdog script. I haven't yet found a way to make it query the McPlots database (credentials problem) so I screen scraped it and saved it as a text file which the watchdog searches for the job. From the McPlots report it calculates the job's viability. For that +4 day job the viability was 2 out of 10, not promising. The script also watches the number of processed events. That task ran for 2 days before processed events rose above 0. As the processed events increases, the script is able to predict completion time with some accuracy (in most cases accurate almost to the minute, so far). Since completion time was well before deadline and the script indicated no warning signs like 'Y out of bounds', it was allowed to continue. The questions are: 1. With so few tasks failing now that the bad Sherpa jobs are being filtered at the server, is it worth spending CPU cycles on a watchdog script? 2. What will happen when we start a new workflow? Will all jobs in the McPlots database initialize to "0 attempts, 0 success, 0 fail, 0 lost" and if so then how will the server filter out the loopers? |

(Message 39388)
Posted 18 Jul 2019 by bronco Post: Oh, joy. Several/many hours of my time that I'll never get back but luckily I have only used this host for Boinc and hopefully it might even be faster as it should clear out all the rubbish my sister left on it. All that work so you can run 1 single core Theory VBox and maybe a Sixtrack simultaneously. That's dedication to the cause. With just a little more work you could put Linux with a small desktop GUI on that machine and run a single core (2 athena threads) ATLAS plus a (Theory or Sixtrack), like I do on my old X2 with 4 GB. Yes, a bit of a learning curve but you could learn enough in a day to get you up and crunching. Anything to get rid of VBox. It's not just the overhead it's the ongoing PITA. |

Glad I didn't. It's easier to have patience with long runners now that the loopers are filtered out. |

Posted 8 Jul 2019 by bronco Post: I don't know how to setup a local proxy. I read the SQUID link and it's outside my wheelhouse. I see "openhtc.io" in the title of this thread but don't know how to do it unless the sequence of commands above do it. The instructions for Squid are a bit confusing but you've got the CVMFS, the Singularity, you're over the hard part. Ask in the squid thread and I'll give you a working example. With 240 WUs DLing.... I just can't see it working nicely without a Squid. I can't even see it working badly unless you have outrageously fast connection and unlimited data. |

(Message 39304)
Posted 6 Jul 2019 by bronco Post: Ignore the increments, they mean nothing. You are caching too many tasks, that is the reason you have results with "Not started by deadline - canceled" status. You need to reduce the number of cached tasks. In your computing preferences what are your settings for "store at least" and "store up to an additional"? Reduce those settings to half of whatever they are now. Then abort any tasks that have not started. Allow at least 24 hours for the new settings to settle out. With a CPU as slow as your Sempron you should never have more than 1 task running plus 1 task waiting to start. Also, check to see if you have throttled the VM. It should be at least 90%. |

Posted 4 Jul 2019 by bronco Post: The filter seems to be be working well. I've caught a few sherpas recently and some have been long runners but they finish successfully. The forever loopers seem to be gone. The filter has obsoleted major portions of my watchdog script, at least for this workflow. Next workflow maybe not so much. Toying with the notion of turning my watchdog into "Sherpa hunter" which rejects all the easy jobs and crunches only sherpas with a bad rep from McPlots. <gloat> Pythias are like sixtrack. Anybody can do 'em. </gloat> |

However, I have nevertheless investigated for myself and here are the results: The filter seems to be be working well. I've caught a few sherpas recently and some have been long runners but they finish successfully. The forever loopers seem to be gone. Thank you, Laurence :-) |

Posted 27 Jun 2019 by bronco Post: What if the limits are just a bit too strict? I assume we're speaking to problems with TheoryN not Theory VBox 1) Set task duration to 4 days (on my hosts it seems 95% finish in < 3 days) 2) Set (deadline + days of grace) = 15 3) Allow users a way to extend the task duration if they wish. 4) Allow graceful shutdown I realize 4 is tricky and might take some time to implement. It may even be impossible. Do 1, 2 & 3 for now. Maybe 4 later. |
