Posted 16 Nov 2022 by Alessandro Freda Post: Welcome back! About the tweaks, BoincStats still shows the project as "retired" is it a problem about the export of xml statistics or is it BS side that needs to be solved ? |

Posted 20 Nov 2018 by Alessandro Freda Post: I sent hum a private message yesterday to which I've had no reply yet. I've not deleted mine, I don't want them going out again wasting someone elses CPU time. These tasks are wasting weeks of crunching. Ok, so you suggest to suspend these WUs ? (to avoid to waste also my CPU time) Anyway deadline and reschedule will come. |

Posted 19 Nov 2018 by Alessandro Freda Post: Same problem on at least 2 my PCs (first running on AVX, 2dn on SSE2), these are some of the "long" WUs: ps_181113_input_107029_2_0 ps_181113_input_107029_1_0 ps_181113_input_107029_3_0 ps_181108_input_31762_6_1 ps_181108_input_31762_5_1 ps_181102_input_10465_1_2 ps_181020_input_169988_4_3 it seems to me that it was an old problem, seen some years ago The question is, it's happening again, or they're a new kind of WU ? I'm erasing them so far ... |

Posted 7 Jul 2015 by Alessandro Freda Post: I'm trying and app_info "avx only", on a xeon E5-2620 (win7 64 bit) and before with SSE3 and ps_150618* WUs cpu time was about 16000 sec, now with avx and ps_150619* WUs cpu time is about 20000 sec. Is this due to diff between WUs or on some avx cpu SS3 are more efficient ? Moreover, using app_info the WUs queue is always empty so seems that CPU stay idle many hours between WUs download. |

Posted 28 May 2015 by Alessandro Freda Post:
BTW if I limit HT via BIOS settings, this will impact other projects that benefit by the HT. Correct ? On a my old xeon initally with HT disabled, I observed a 5% RAC increase 30 days after enabling HT, could be realistic ? Could be correct say that highly optimized (double precision) apps do not benefit by the HT, while less optimized benefit more by the HT ? |

Posted 24 Apr 2015 by Alessandro Freda Post: ie (this is the one I found on the forums and use with W7 / i7 4770K / HT OFF) why HT off, performs better with avx ? I've an "old" xeon E5-2620, could I try to use app_info to switch from sse2 to avx ? |

Posted 4 Sep 2013 by Alessandro Freda Post: Any news about the problem ? On my PCs seems that the download fails are more than successful one. |

Posted 27 Aug 2013 by Alessandro Freda Post: Thank you. So how many "slow" WUs must be processed by validator, to choose the fastest client ? |

Posted 27 Aug 2013 by Alessandro Freda Post: Is normal that the same PC download (today) WUs both for SSE2 and non-SSE2 client ? http://asteroidsathome.net/boinc/results.php?hostid=19080&offset=0&show_names=0&state=2&appid= |

Posted 16 Jan 2013 by Alessandro Freda Post: Thanks for the detailed reply, i understand now This is my host: http://asteroidsathome.net/boinc/show_host_detail.php?hostid=7663 no OC (700MHz) and Radioactive and QCN clients running on their sensors, it's at 73% afer 2d 10h Despite the low consumption rasPi not seem to have an efficiency flops / watt interesting. But in the next few months could be interesting to evaluate this: http://www.gizmag.com/parallella-supercomputing-for-the-masses/24764/ |
