Posted 1 day ago by Bryn Mawr Post: For those looking to upgrade their systems for crunching Rosetta work (or other CPU based projects), don't want to wait for Ryzen3 to be released (and have more money than sense...) I joined because I could not think of a reason not to give someone a copy of my credits. |

Posted 14 days ago by Bryn Mawr Post: Why are there no usefull descriptions in the name of the work unit like "cancer" or "covid". I would suggest that the naming of the batches is to help the researchers keep track of their work rather than to tell the volunteers what they’re donating their computer resources to. |

Posted 19 Sep 2020 by Bryn Mawr Post: The Boinc Programmers think it works just fine and your 'tweaking' is unneccessary from their perspective. You obviously have never worked in a development environment. Take it from me, your suggestions go well beyond the odd tweak. |

Posted 18 Sep 2020 by Bryn Mawr Post: The Boinc Programmers think it works just fine and your 'tweaking' is unneccessary from their perspective. Do you really not see that the amount of work that you are suggesting that they undertake is well beyond the capacity of the number of programmers available to the project. |

Number crunching :
Credit varies by factor of one hundred for equal CPU time
(Message 98969)
Posted 11 Sep 2020 by Bryn Mawr Post: OK, I’ve just had a look at your setup and the first thing I would say is, unless you have a really unreliable ISP, cut down your work cache. A setting of 0.1+0.2 day’s work is far more manageable. Looking at the WU that was awarded 4.03 credits I think I can see why. It failed, twice, and called boinc-finish three times reporting 46, 1 and 1 decoy. Whenever this happens the credit scoring system appears to ignore all but the last finish command so you were credited for 1 erroneous WU and the 46 good WUs were lost. |

Posted 11 Sep 2020 by Bryn Mawr Post: The credit system is not a big deal for me, but I realize that I don't understand the algorithm. Is it discovery based? Rosetta is an unusual project in that work units run for a fixed time rather than do a fixed amount of work. The amount of work that your computer does in that time can vary greatly and the credits can reflect this. There can also be a settling in period for new installations or new apps as Boinc works out the work being done. If you look inside the work unit you will see details of the number of decoys completed. For a given starting position the number of decoys is a good measure of work done but it depends on the complexity of the protein being processed and so even this is not a strict measure of the credits you should receive. As you can tell from this ramble I don’t fully understand the credit system, it is an arcane process at the best of times, I tend to put a single WU with an odd credit score down to life’s experience, shrug, and walk away :-) |

Posted 6 Sep 2020 by Bryn Mawr Post: As usual I’m guessing, but I’d assume the Tasks ready to send are a buffer that the server maintains from which it can immediately service client requests for new work. If that buffer gets topped up from the Total queued jobs – which is what people are pointing out is getting smaller, and at the current rate will be exhausted before the end of the day – we are indeed about to run out of work. Give it a few more hours, and we’ll find out… You live and learn - thank you :-) |

Posted 26 Aug 2020 by Bryn Mawr Post: Hello all This is not really a question for Rosetta, it’s a question relating to Boinc Stats, but let’s have a go anyway. The problem is not associated with your team, the rac you are looking at is personal to yourself and the processing that you’re doing. If you log into BOINCstats.com and look at your detailed stats/last 60 days within BAM you’ll see that (taking Rosetta as an example) over the past few days you’ve been earning about 800 credits per day. If you go back a week you were getting about 1300 credits per day, indeed, on the 15th it was over 2000 credits. If you go back a month the figures are back down below 1000. There are a couple of possibilities, have you changed the amount of time you’re using your computer or leaving it switched on? Does the pattern of credits match periods of hot and cold weather in your part of the world? Your I7-640LM is not the most powerful CPU and laptops can be prone to overheating if pushed hard which means that you could easily be throttling in warm weather. |

Posted 25 Aug 2020 by Bryn Mawr Post: If I'm not mistaken, the BIOS shows the "ask" or VID voltage. Not what the Vcore really is under load. I like the zenpower driver because it uses the direct telemetery (SVI2) off the VRM's that supply the Vcore and Vsoc voltages like the Windows utilities like HWinfo. You can talk apples to apples when comparing systems with Windows users. Wonderful. My monitor of choice is PSensor but I'm not precious about it. |

Posted 24 Aug 2020 by Bryn Mawr Post: It validated as valid instead of error? Is that normal? I also got the same amount of credits for this task as my wing-man despite having half their run-time, somehow. Out of order and totally unnecessary :-( |

Posted 24 Aug 2020 by Bryn Mawr Post: I would have liked to monitor it under load but it’s the one time Ubuntu has let me down - I cannot find a utility outside of the bios that will report the real time value Interesting, it’s reporting a vCore of between 1.219v and 1.263v, mostly to the lower end of the scale, which is far more reasonable than the 1.445v (-0.1v) it was reporting in the bios. The effective CPU frequency is fairly steady at 3,900 with a max of 3,925 so no damage to performance so far. |
