I apologise if this is answered somewhere already, but I can't find it. My dual core intel is only running one unit at a time. I think I've tried all the suggestions I could find already posted. The system and bios show dual core, the preferences are web based and show multiple processors. Can someone there help? Jim |

After you changed the web preferences, did you go BOINC Manager->Advanced view->Projects->Select Seti->Click Update? Your computer summary shows you to be using one CPU. |

After you changed the web preferences, did you go BOINC Manager->Advanced view->Projects->Select Seti->Click Update? That is his Operating System reporting a single CPU, not him using a single CPU. BOINC will not use more CPUs than the operating system reports. On Windows, this means upgrading your Hardware Abstraction Layer of HAL. BOINC WIKI |

this might help, as a preference vista comes as using one core. try this |

After you changed the web preferences, did you go BOINC Manager->Advanced view->Projects->Select Seti->Click Update? I've tried the Update without effect. I'm using Windows XP, if that makes a difference. Jim |

After you changed the web preferences, did you go BOINC Manager->Advanced view->Projects->Select Seti->Click Update? The problem is that your OPERATING SYSTEM is reporting one CPU to BOINC. You need to fix your OS so that it is reporting the correct number of CPUs.

The system and bios show dual core. But does it also show that it is enabled? Go back into your BIOS and check if dual cores/multiple cores is enabled. Make sure you save changes on exiting the BIOS. In my case, when I enabled Hyper threading, Windows XP updated itself automatically. It may not always do this, so in such case follow the steps: 1. You will need Service Pack 2 for XP for this, so if you do not have it, install it from Windows Update. 2. Use search to find ntkrnlmp.exe and halmacpi.dll and copy them to your c:\windows\system32 directory. 3. Use search to find boot.ini and open it in your text editor then find the following line: multi(0)disk(0)rdisk(0)partition(1)WINDOWS=â€ÂMicrosoft Windows XP Professional†/fastdetect /NoExecute=OptIn (or something of this sort) and replace that line with: multi(0)disk(0)rdisk(0)partition(1)WINDOWS=â€ÂXP Professional MP†/fastdetect /kernel=ntkrnlmp.exe /hal=halmacpi.dll Make sure there are no line breaks in that line. 4. Reboot your computer. It may go through an installation of the new kernel, just continue to click Yes and Install (or which ever you get) until done and that's it. |

The system and bios show dual core. trying that now. Jim |

The system and bios show dual core. no, there's nothing there that seems to help. I'm pretty much where I started, i.e. one file being processed. I'm on XP home, for what it's worth. Jim |

When you press CTRL + ALT + DEL and go to the Performance tab, of how many CPUs does it show the performance graphs there? See also this page and make sure you follow the link to the hotfix and install it. It may not have been added to SP3. |

Check Advanced menu - Processor usage tab On multiprocessors, use at most 100 % of the processors You could use the 'clear' button to revert to using the web based preferences. |

I have a similar issue but on a dual core Xeon system running Fedora 9. Until this week SETI has run fine and would show two work units being processed in parallel. Fedora updates recently included an update to BOINC client - to 6.2.15 and since re-starting the client to run the new version SETI is only processing one work unit at a time. I have not changed the preference settings on the web. Fedora knows the system is dual core. System monitor shows two CPUs and reports the following hardware: Fedora Release 9 (Sulphur) Kernel Linux 2.6.26.5-45.fc9.x86_64 Hardware Memory: 2.0 GiB Processor 0: Intel(R) Xeon(R) CPU 3060 @ 2.40GHz Processor 1: Intel(R) Xeon(R) CPU 3060 @ 2.40GHz If I run the CPU benchmark in SETI/BOINC it reports Sat 04 Oct 2008 09:22:53 AM BST||Running CPU benchmarks Sat 04 Oct 2008 09:23:25 AM BST||Benchmark results: Sat 04 Oct 2008 09:23:25 AM BST|| Number of CPUs: 1 Sat 04 Oct 2008 09:23:25 AM BST|| 1645 floating point MIPS (Whetstone) per CPU Sat 04 Oct 2008 09:23:25 AM BST|| 6962 integer MIPS (Dhrystone) per CPU Sat 04 Oct 2008 09:23:26 AM BST||Resuming computation So, it looks like there is a problem with SETI/BOINC detecting dual core systems in version 6.2.15 Anyone else any insight into this?

So, it looks like there is a problem with SETI/BOINC detecting dual core systems in version 6.2.15 Go to your computing preferences under your account and set On multiprocessors, use at most xxx% of the processors to 100%. The old setting of On multiprocessors, use at most x processors no longer works under BOINC 6. Also make sure that this setting is 100% in your local advanced preferences, if you use those (from BOINC Manager). The percentage of CPUs used is an integer number, so even 99% equals one CPU. |

Jord Many thanks. This did the trick. Dave |
