BOINC client :
Problem with cpu use on HyperThreading & multicore app
(Message 15552)
Posted 24 Feb 2008 by Travis Post: To solve your problem and slowdowns in all your projects try to set up in General preferences "On multiprocessor-systems, Use at most >1< processor" or change that entry in global_prefs_override.xml. But either way, aren't BOINC projects supposed to run on idle CPU time and should always throttle back no matter how many cores are running BOINC apps? I understand the role the OS plays when it comes to scheduling tasks, but it still doesn't make sense to limit BOINC's scheduling to 1 CPU in regard to multiple virtual/physical cores when running multicore applications. I still need to check out this behavior on a P4-D. |

Posted 9 Feb 2008 by Travis Post: What project(s) are you running? CPDN, Rosetta, LHC, and Einstein. I've watched them all exhibit this behavior, that's why I thought it might be BOINC instead of something project-specific. HT means not Dual-Core. You have only a SingleCore-CPU with 2 virtual Cores. First real Dualcores for X86 was P4-D or A64-X2. This is true. Windows doesn't know the difference. And since I'm not dealing with the Pentium-D or X2 (or higher) CPUs, I'm back to pointing out I'm seeing this on a HyperThreading Enabled CPU. Until I get to work on Monday I can't verify if I can reproduce this on a P4-D or Core2 CPU and isn't part of my original post anyway. :) |

Problem with cpu use on HyperThreading & multicore app

Posted 8 Feb 2008 by Travis Post: I'm noticing a problem with the way BOINC (v5.10.20) schedules tasks to run in the background on Vista Business (32-bit) with Pentium-4 HT enabled CPUs. The client will start up one project per CPU core to run in the background with idle priority. So far so good. But when I run x264, a multicore aware video encoding application, BOINC is not respecting something and never lets go of one of the cores and forces that other core to share time with x264. This of course gives lackluster encoding performance but can only be remedied by stopping the BOINC service. Can anyone verify this? |

Posted 8 May 2007 by Travis Post: The installation problem I mentioned above was solved in v5.9.10. All worked without fail, no errors in the system event log. Just FYI. :) |

5.9.x problem reports
(Message 9998)
Posted 5 May 2007 by Travis Post: Installed as service into the default location (C:\Program Files\BOINC). While it was installing as service I tried a few things- after the error appeared, I sent into services.msc and changed the logon account from the one I was on in AD to a local user in the administrators group, went back to the boinc installer and tried retry and the same thing .. also tried using local system account with and without enabling interaction with the desktop. One of our developers took a look at the error and his thought is the error has something to do with a Visual C Runtime library from Visual Studio Express 2005 - though a "msvc80.dll" doesn't actually exist for redistribution. I can't vouch for any truth to it, but I can't find it on the net to download. |

Dependent Assembly Microsoft.VC80.CRT,processorArchitecture="x86",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="8.0.50727.762" could not be found.

Event 11708: Product: BOINC -- Installation operation failed. Basically, BOINC refuses to install and gives an error message on the screen that states "Can not start boinc, Retry / Cancel." When I click retry, another of the above entries is added to the Application Event Viewer. This problem doesn't exist when I use the 5.8.x series installer. |
