Posted 13 Jan 2014 by Ananas Post: I'm not sure wether the problem lays here or on the BOINCstats site ... http://boincstats.com/en/stats/134/host/list/12/0/0 shows the two top hosts in this project both with 86400 daily credits for yesterday. 86400 is 60*60*24, a value defined in the core client as the limit for short time debits - it would really be a strange coincidence, if both top hosts had exactly this value as their daily output. I currently don't have an idea, what might cause this, the host detail pages on BOINCstats (best 10 days and graphs) show some higher values - but it might somehow be related to the server side BOINC upgrade. |

Posted 30 Nov 2013 by Ananas Post: Some (a few) projects experiment with multithreaded applications but the majority of BOINC projects works single threaded. Many BOINC users run a project mix on their computers, running multiple BOINC tasks at the same time is just normal. p.s.: you can limit the number of threads in the Computing preferences, the value to modify would be On multiprocessors, use at most xx processors |

Posted 25 Sep 2013 by Ananas Post: On scheduler contact : Message from server : Server can't open database and it took forever to open this forum page to post a new message. p.s.: I guess the message is caused by a timeout, not total malfunction. |

Posted 7 Sep 2013 by Ananas Post: Boinc does not allow you to release an application which would be only available to specific Windows versions? If you want to support a specific CPU feature, that BOINC doesn't report, you could use a method similar to the RNA-World one : They deliver only one ZIP (for each OS basic type) that has everything : common files, SSE4 version, SSE3 version ... basic version. Plus they use an unzip "wrapper", that checks the CPU features, unzips the common files, then checks the ZIP file for the best version that fits the CPU. If unavailable, it checks the next one and so on. Advantage : It will work even with ancient BOINC versions, that are much older than the date the CPU feature has been introduced - without the need for am optimized app_info.xml. |

Posted 18 Aug 2013 by Ananas Post: Credits are a fun thing, used for competitions (teams or persons), success control for the efficiency of your host and stuff like that. There has been a university that payed BOINC credits with ice cream but I guess that has been an offer for their own students - I like the idea though (as much as I like ice cream). There is a Bitcoin BOINC project but I haven't checked what they exactly do. p.s.: depending on your location, on the tax office and on the project it _might_ be possible to make the electricity you invested for crunching into a tax deductable donation (sorry, I'm not so sure how to word it, I hope it is understandable) - but I guess that's quite a hassle in most cases, especially as too many factors influence the ratio between the watts used and the credits earned. |

Posted 18 Aug 2013 by Ananas Post: Sounds very much like a missing DLL. VC++ runtime not static maybe? Especially as the optimized version should rather be larger (loop unrolling) than smaller than the regular version. In fact it is about half the size. |

Posted 18 Aug 2013 by Ananas Post: Slightliy OT : I'm using an outdated core client, it doesn't report the CPU capabilities properly. So I downloaded the 32bit SSE3 version and now I'm trying with this app_info.xml : <app_info>
<app>
<name>period_search</name>
</app>
<file_info>
<name>period_search_10000_windows_intelx86__sse3.exe</name>
<executable/>
</file_info>
<app_version>
<app_name>period_search</app_name>
<version_num>100</version_num>
<file_ref>
<file_name>period_search_10000_windows_intelx86__sse3.exe</file_name>
<main_program/>
</file_ref>
</app_version>
</app_info>(Win x86 sse3 - Intel C2Q CPU) No result finished yet but I can already tell that the speed went up tremendously (estimated by factor 5). p.s.: I forgot that BOINC removes all results when you switch between BOINC downloaded application and anonymous platform (it does a complete project reset) so I lost two already started results. So before you try this yourself, crunch down your cache and report everything before switching. |

Posted 18 Aug 2013 by Ananas Post: I wonder if the x64 version without SSE support is even required. For RNA we made an SSE2 version for x64 "just in case" but is there even any x64 CPU without SSE3 (only talking about 8086 based architecture of course) ? |
