I have been watching my Rosetta tasks. Even with the "12 hours requested" I am regularly getting what appear to be 8 hour tasks. What I am not getting is the 2-3 hour tasks that seem to be the group average for the beta task on the server page. Is there ANY chance a 2 or 3 hour task is more productive? A lot of volunteers seem to be going with it. Proud member of the O.F.A. (Old Farts Association) |

Rosetta tasks usually run for a set amount of time, and execute several models during that time, with diffrernt rng seeds. For some reason some workunit types run very fast, and produce lots of data . For example my task reached model 16 in 10 minutes of cpu time. |

I have been watching my Rosetta tasks. Even with the "12 hours requested" I am regularly getting what appear to be 8 hour tasks. 3hr runtimes aren't chosen by volunteers. They're 'default' runtimes that are screwed up within the task by the researchers. It's a mistake (IMO but I'm convinced I'm right). Default runtimes are <all> intended to be 8hrs. That's why Boinc is forced by Rosetta to show all unstarted tasks as 8hrs, even if other settings contradict that runtime. The task runtimes screwed up by researchers only run 3hrs by mistake. Those set to be a different time by the volunteer (eg you and me at 12hrs) run that time, but Boinc only realises 2/3rds or 3/4s through the task to adjust the remaining time - whether up to 12hrs or down to 3hrs. <No chance> the shorter runtime is more productive. I don't think <any> change to runtime improves credit/hr, except the start/stop overhead is less significant for longer tasks and shorter tasks waste the work that's provided to us, so we may run out of tasks sooner than expected. <Never> run any less than 8hrs (intentionally). If your runtime setting is "default" and you mean that to be 8hrs, better (currently) to set runtime explicitly to 8hrs, not 'default' Credit is awarded for the number of "decoys" completed <within> each task within your chosen runtime. The quicker your machine, the faster each decoy is completed, the more decoys you can complete within your runtime, the more credit you get. That's essentially it. After each decoy, the average time per decoy is worked out. If you have sufficient runtime left to complete another decoy, you do so. If you don't, the task ends. That's why tasks don't run exactly to your runtime. Sometimes a bit shorter, sometimes a bit longer. It's also why the countdown on runtime never drops below 10mins remaining, but then suddenly ends. The task doesn't ever know when the current decoy will complete until it does. Then sees there isn't time to do another, so it ends. ![]() ![]() |

Two more Validate errors tonight, meaning 2x12hr tasks not being awarded credit. Another unheard appeal for the daily job that cleans this up to be reinstated. Probably caused by some disk errors I'm getting locally, but annoying nonetheless :( ![]() ![]() |

I note that this host: https://boinc.bakerlab.org/rosetta/show_host_detail.php?hostid=6282139 I've got another idle few minutes to do some investigating. We worked out the system you were comparing to was more powerful than yours, explaining why it had better results. Working out its credit over the last 11 24hr tasks returned it's averaging 908 credits/task Looking at yours now, over the last 20 12hr tasks returned you're averaging 444.5 credits/task - equivalent to 889 credits/task if running 24hrs Still behind, but now very much closer. Also, your error'd tasks have reduced from about 1100 out of ~3000 (I worked out a while back it was 27% of tasks you downloaded) to 201 out of 2153 - 9.3% - and it'll drop down further once the older tasks age out. Much cleaner. Comparing with yourself, using your info at Boincstats Pre adjustments you made here, from April 1st to May 8th, your average credit/day was 95,340 Since then it averages 116,430 - an increase of 22% per day. Tbh I didn't expect any increase at all, as nothing we all suggested should have made any difference, but maybe by ensuring you didn't get timed out tasks and cancellations from the server and didn't miss any deadlines there was some free benefit in there none of us noticed. I suspect it's just a matter of getting all the credit your runtime deserved, rather than missing out on bits and pieces here or there. Either way, more is more. No tasks are lost nor hoarded, no deadlines missed, no credits lost, no threads unutilised, quicker turnaround times, fewer server hits. So much winning for everyone. A highly productive exercise. ![]() ![]() |

So how likely is my system to approach 116K rac? Proud member of the O.F.A. (Old Farts Association) |

Comparing with yourself, using your info at Boincstats The period since May 8th is very short and credits vary from day to day. Your average credit since then has dipped and now averages 115.073 Someone else will be better placed to say how long it takes for your RAC to reflect more recent results, but my feeling is that you need to allow about a month, if not 2 months, not just 8 days. On the Boincstats link, If you click across to the Charts tab, the 4th chart shows your RAC by two different calculation methods. I have to admit to not knowing how each is calculated, but you can see how it's varied over time. I also note your Task Errors are now down to 150 out of 2092 - 7.2% (down from 1100 out of ~3000 - 27%) - the vast majority of errors (all bar 10) caused by the project, not by your machine. ![]() ![]() |

Someone else will be better placed to say how long it takes for your RAC to reflect more recent results, but my feeling is that you need to allow about a month, if not 2 months, not just 8 days.Changing settings on a system that has been doing work for a long period of time without interruption (either the system or the project), it takes 2-4 weeks for those changes to fully flow through and be reflected in RAC. That is for a system doing a single project with little to no cache. The larger the cache, the more projects the system is doing, the more fiddling with the system in the mean time or interruptions in work, then the longer it will take for RAC to settle down to it's new range (1-3 months, or more if work supply/system/settings fiddling continue to occur).

Two more Validate errors tonight, meaning 2x12hr tasks not being awarded credit. Another validation error, this time on a different PC. The only common factor is I was working on it at the time and had a system crash. Partly heat-related too. Still annoying. A couple of thousand missing credits per week recently... ![]() ![]() |

I haven't received any Rosetta tasks in a month or so. I'm about ready to give up on Rosetta. It's become too unstable and unreliable for me. I just want to download tasks and let BOINC and my computer process them with little input required from me. You guys suggested some fixes and work-arounds. But I can't implement any of those because I am a digital dolt. S. Gaber Oldsmar, FL |

I haven't received any Rosetta tasks in a month or so. There are a number of other CPU oriented projects out there that should be pretty much plug and play. DENNIS@Home and World Community Grid are projects I am running. Both of these are biology/medicine projects. I also run Asteriods@home, primegrid, and milkyway@home. ===edit=== Let's not forget Einstein@Home :) I am assuming you were not able to add the two lines to the hosts file? Or even find it? Let us know how some of the other projects are running for you. Tell us about your computer, operating system and video card? Tom M Proud member of the O.F.A. (Old Farts Association) |

Tom: I request updates from Rosetta almost every day, but get no work. The server status shows zero tasks ready to send. As I said, I will not delete Rosetta from my project list, but I don't have much faith in getting new work any time soon. S. Gaber Oldsmar, FL |

This computer is already running WCG, Einstein, Milky Way and Asteroids, in addition to Rosetta. It has been crunching them for some time without problems.

I thought I posted this days ago, but maybe I didn't send it for some reason. Well, I made up for that. Sorry for the triple-post... Couple of things I've noticed in the last few days: Compute errors seem to have disappeared in the last week. We seem to be in the middle of a clean run, which is good as queued tasks have dropped to under 5million, while we're under 70k of in-progress tasks - still hand to mouth. My uncredited Validate Errors have dropped to only 1 across all my PCs, but I note Tom M has suffered 15, losing ~6600 credits and his average has dropped from 115k to 106k - still 11% higher than before, but much lower than it initially jumped up to. Otherwise, steady as she goes ![]() ![]() |

I thought I posted this days ago, but maybe I didn't send it for some reason. I just swapped the MB into a Mining Rack and added back the three Titan V's I used to run on it. Then had to troubleshoot for hours and had a brief house power outage so my RAC has suffered. Based on Free-DC, I am hopeful I will get back up past 103K and maybe as high as 117K on my RAC. I wonder what I did which caused validate errors? https://boinc.bakerlab.org/rosetta/show_host_detail.php?hostid=6327403 Crossing Fingers. Proud member of the O.F.A. (Old Farts Association) |

I try not to let it overheat by keeping it under 190 degrees F.I haven't received any Rosetta tasks in a month or so. Sid: I did just as you suggested. Copied everything into Notepad. It's still there at the bottom of the list. I updated Rosetta like you said. But nothing happened that I could perceive. I hit the Update tab several times per day, with similar results (i.e., nothing). Later, AMD did send two error messages which then went away. I have checked the typing of my Notepad entry to make sure it is exactly as you wrote it in your response. So I don't know why your patch didn't work. Maybe it's another example of my digital dolthood. But I'm not bothered by the lack of Rosetta tasks (aside from not contributing to the research). The computer is very happily crunching Milky Way, Einstein, Asteroids and WCG. To be honest, Rosetta's 3-day completion requirement sometimes posed problems trying to keep up with all of those. But I thank you for the attempt. Sincerely, S.Gaber |
