Posted 18 Dec 2023 by dcdc Post: Interesting! Looks like you got one of not many tasks - 70 in total. |

Posted 20 Feb 2021 by dcdc Post: Any idea why these tasks are for Linux vbox? I would have thought the Linux and Windows vbox would be the same as far as the tasks running in the VM are concerned. |

Posted 14 Feb 2021 by dcdc Post: I've upgraded to the vbox version of BOINC and added Ralph on one machine. Will add more as I get around to it unless any tasks appear, in which case I can add a few quickly. |

Tasks not running on Android 10

Posted 10 Apr 2020 by dcdc Post: It's working now. I have no idea what I changed. Running BOINC 7.4.53. Turned off battery optimisation for BOINC in the Android App settings. Not sure if I did something else too... |

Posted 5 Apr 2020 by dcdc Post: Ok - thanks. It's useful to know it's not an Android 10 issue. Maybe OnePlus are doing something strange that's stopping BOINC or the task from running, unless it's just my device. I've turned off battery optimisation for BOINC, but that hasn't helped. |

Tasks not running on Android 10

Posted 2 Apr 2020 by dcdc Post: My phone (OnePlus 7T - Android 10) won't run Ralph tasks and I don't think it will run any other projects either. My old OnePlus 3 (Android 9) runs everything that it downloads. This phone will download tasks but they sit at 1 or 2 seconds forever. I am wondering if it is an Android 10 issue as posted here: https://github.com/BOINC/boinc/issues/3290 Specifically, it seems that Android 10 needs the tasks built with a newer SDK. Specifically this post:
Is anyone else experiencing this? I understand it won't (and shouldn't) be high priority. D |

Ralph and SSEx

Posted 28 Dec 2015 by dcdc Post: My understanding is that Rosetta is made up of modules, so is the sensible thing to do to take one of the smaller/most commonly used modules and have a look at optimising the code there? |

Posted 20 Oct 2015 by dcdc Post: I would exit BOINC and restart it in that situation rather than aborting them. Yes exactly, although flagging it up as an issue is useful as it obviously shouldn't happen and something needs fixing (whether that's in Rosetta or BOINC or elsewhere). |

Posted 9 Oct 2015 by dcdc Post: Eliminating an non-SSE2 version of Rosetta would eliminate Pentium 3 and Athlon XP or earlier CPUs, so I'd guess less than 0.1% of output. |

Posted 1 Feb 2009 by dcdc Post: Yes I know it's a still used application. my guess would be that some of the devs are using mini but some are still working on code that hasn't been ported yet... |

Posted 30 Jan 2009 by dcdc Post: I've just stuck a virtual machine on ralph (so if it goes wrong rosetta will pick up the slack on the real pc) and it downloaded 5.98 but i can't see any mention of that app on the msgboards - is it right or should it've downloaded rosetta mini? |

Bug reports for 5.66-5.68
(Message 3202)
Posted 15 Jun 2007 by dcdc Post: Yes, the failures do attempt to connect directly back to the project to report additional traces. And unfortunately with ZA, each version of Ralph AND Rosetta must be enabled. Please enable the current v5.68 by clicking the program control, and then the add button and selecting the .exe from your BOINC/projects folder zonealarm used to have a 'changes frequently' option that you could give to a program so it always allowed internet access. Don't know if that was just ZA Pro or not though... |

New crediting system
(Message 2184)
Posted 19 Aug 2006 by dcdc Post: I think it is way easier to fake the numbers of decoys generated than to fake the internal benchmark. So the currently tested system is not fake-proof either. I'd be very suprised if that were true, but I'd like to hear DK's thoughts on the subject. |

New crediting system
(Message 2182)
Posted 19 Aug 2006 by dcdc Post: I'll throw something else in here. One advantage of the proposed new credit system over any that use benchmarks is credit-crunching alignment, which is the very thing we've been requesting here. Benchmarks are rarely perfectly aligned with the work to be done. As one example, the size of CPU cache may play a large part in crunching ability, but it is rarely a factor that influences benchmarks as they tend to be small and quick. By not using a benchmark, or rather using a whole decoy as a benchmark, the credits are exactly aligned with the credit system. The only issue remaining is that there is variation in time taken to produce decoys on any given machine, but no variation in credit awarded. If this averages accurately, then I believe it to be the best system. If someone tweaks their computer by, say increasing the FSB, which removes a CPU-RAM bottleneck, this is unlikely to be picked up in any benchmark, but will show up in this system. The other option of course is to try and make the benchmark realistic. This is difficult, because of the size and variation in algorithms used within the WUs. The 'new credit system' includes for this. My final point regards the golden machines used. I've posted somewhere - here or at Rosetta - that the makeup of the golden machines needs to reflect the wild population for the following reason: If the golden machines are 10 AMDs running Windows, which are very good at 2 in 10 WUs (as they fit into a small cache), but take much longer with the remaining 8 (as they are slightly larger than the AMD cache) then the first 2 WUs will be assigned little credit, while the remaining 8 will be assigned more. In the wild, although a Pentium isn't affected by the difference between the WUs sizes due to its larger cache, it will still get the credits that reflect how the AMDs crunched them. This may be a minor point with regard to CPU cache sizes (or it may not), but there are a great number of factors that could influence this, including whetstone performance, dhrystone performance, CPU cache size, FSB/HyperTransport speeds, RAM availability etc... The place that matches the wild population of computers the most is, of course, the wild population! Thats my current take on a credit system. I can see that a well aligned benchmark can be more accurate in the short term, which is good for those wanting to push their computers, but after a week or two of crunching I'd be suprised if this system didn't prove more accurate. cheers Danny |

Posted 16 Aug 2006 by dcdc Post: prior to the currently in-testing credit system, I thought that flops counting was the ideal, with the benchmark as either a library to be included in the BOINC code during compilation (don't know if it'd be possible to create a moduel that isn't 'tamperable'), or a standard benchmark to be included in the project apps. Infact I remember my very first DC post over at UD said the very same thing back in 99 or 2000! I haven't seen anything that says that this is an accurate system though- as Ethan says, what value to you assign to FPU operations over Integer operations etc. There is some arbitration even in that system isn't there? (I might be wrong - my understaning of programming is pretty minimal beyond VB...) |
