I recently got a new machine (Windows 7 installed) with a Core i7 processor(8) and a GPU, and when I installed the latest version of BOINC all 8 processors and the GPU were running. Yesterday I noticed that the GPU is still crunching, but no other processors are doing anything. I downgraded BOINC from .41 to .36 but that did not help. I think this may have started when I did my last Windows update, which was an IE8 security patch. |

I think this may have started when I did my last Windows update, which was an IE8 security patch. Does your cc_config.xml file have the line <ncpus>0</ncpus> in it? This used to be a way to default to use all CPUs, it now turns off all CPUs. ![]() ![]() BOINC WIKI |

I think this may have started when I did my last Windows update, which was an IE8 security patch. I will check when I get back to that machine. I did change my preferences online to use 9 processors (it was set at 2, but it ran all 8 anyway until recently). |

Well, I can't find that config file. |

I did change my preferences online to use 9 processors (it was set at 2, but it ran all 8 anyway until recently). You changed an obsolete preference (kept for downward compatibility). The actual one is On multiprocessors, use at most 100 % of the processors Enforced by version 6.1+ Gruß, Gundolf [edit]Is there a line like "Preferences limit # CPUs to..." or similar in the BOINC startup messages?[/edit] |

Well, I can't find that config file. If you didn't create it yourself (in the BOINC data directory), you won't find it. It isn't created automatically.

No, the startup message does recognise that I have 8 processors: 10/30/2009 6:13:44 PM Starting BOINC client version 6.6.36 for windows_x86_64 10/30/2009 6:13:44 PM log flags: task, file_xfer, sched_ops 10/30/2009 6:13:44 PM Libraries: libcurl/7.19.4 OpenSSL/0.9.8j zlib/1.2.3 10/30/2009 6:13:44 PM Data directory: C:\ProgramData\BOINC 10/30/2009 6:13:44 PM Running under account ******** 10/30/2009 6:13:44 PM Processor: 8 GenuineIntel Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz [Intel64 Family 6 Model 30 Stepping 5] 10/30/2009 6:13:44 PM Processor features: fpu tsc pae nx sse sse2 pni mmx 10/30/2009 6:13:44 PM OS: Microsoft Windows 7: x64 Edition, (06.01.7600.00) 10/30/2009 6:13:44 PM Memory: 7.99 GB physical, 15.98 GB virtual 10/30/2009 6:13:44 PM Disk: 922.72 GB total, 791.29 GB free 10/30/2009 6:13:44 PM Local time is UTC -10 hours 10/30/2009 6:13:45 PM CUDA device: GeForce GTS 240 (driver version 18627, compute capability 1.1, 1024MB, est. 65GFLOPS) 10/30/2009 6:13:45 PM Not using a proxy |

10/30/2009 6:13:44 PM Data directory: C:\ProgramData\BOINC This is where you would find your cc_config.xml file. It is the same one where you define the debug flags. If it is not there, then you do not have one. ![]() ![]() BOINC WIKI |

10/30/2009 6:13:44 PM Data directory: C:\ProgramData\BOINC It's not there. But for a day or so, all 8 processors and my GPU crunched. I dutifully ran Windows Update when I was told, and after one of these updates, I noticed only the GPU was crunching. |

And you do have CPU tasks (6.03 or AstroPulse) ready to start? Gruß, Gundolf Computer sind nicht alles im Leben. (Kleiner Scherz) ![]() SETI@home classic workunits 3,758 SETI@home classic CPU time 66,520 hours |

Can't tell how many tasks you have, and what app the're for, since your computer's are hidden. Claggy ![]() |

I have AP turned off but this particular machine has several hundred tasks ready to start. I have only one project, SETI@home, and it that curnches 100% of the time. |

I have AP turned off but this particular machine has several hundred tasks ready to start. But that could easily all be CUDA tasks, hence my question earlier. Look at the Application column of the Tasks tab. Gruß, Gundolf Computer sind nicht alles im Leben. (Kleiner Scherz) ![]() SETI@home classic workunits 3,758 SETI@home classic CPU time 66,520 hours |

I have AP turned off but this particular machine has several hundred tasks ready to start. Yes, that's it. I'm new to this CUDA stuff and didn't notice that all the work left on my machine is only for the GPU. I wasn't even aware that there were different tasks sent out for CUDA and for other processors. I guess I'll get more work for those idle 8 when it is available. Thanks to all for your help. |

I have AP turned off but this particular machine has several hundred tasks ready to start. The tasks are actually the same, but they are assigned to different executables at the time that they are sent to your computer. ![]() ![]() BOINC WIKI |

I have AP turned off but this particular machine has several hundred tasks ready to start. You can have more work for your idle CPU's now if you want. The program "Reschedule" can make a percentage of your GPU work crunch on your CPU's. Only takes a minute when you get used to using it. You'll need to make an account at Lunatics. The site will ask for your password before it lets you download Reschedule.http://lunatics.kwsn.net/index.php The download link for Reschedule 1.9 http://lunatics.kwsn.net/index.php?action=dlattach;topic=626.0;id=2749 Use the program WinRAR to unpack it. Then you just double click the .exe file when you want to run Reschedule. Uncheck "Only move VLAR to CPU" and use the slider to get the percentage of work you want moved to your CPU. You can use it to move more work to you GPU's to when you want. On windows Vista 64bit you have to manually put in the path to the BOINC folder and data folder every time you use it.

Core i 7 is not really an 8 processors but a quad with hyperthreading |
