Hey guys, I've tried this method [http://setiathome.berkeley.edu/forum_thread.php?id=76856&postid=1648389#1648389] to get multiple WU's going on my gpus, however boinc still only shows 1 WU per gpu even after putting the app_config.xml in the right place. I've got an EVGA 1070 FTW, Sapphire HD7950 OC and the Intel on board graphics of my i5 4670 going at it. Any help would be appreciated, thanks! |

Hey guys, I know this will sound simplistic but have you also added the "use all gpu's" to the cc_config.xml file? <cc_config> <options> <use_all_gpus>1</use_all_gpus> </options> </cc_config> And have you stopped Bonic completely and restarted it? When I first installed a 2nd GPU I didn't have cc_config.xml in there. Then I created the file and told Bonic to re-read the config files. Still only one gpu. Only when I stopped and restarted Bonic did it recognize my new GPU. Hopefully, someone else will weigh in. Tom A proud member of the OFA (Old Farts Association). |

Hmm that's interesting, I also don't have the cc_config file. I guess I should make one then |

Okay, added the CC_Config.xml file Rebooted the manager after getting it to check config, and also check config again after reboot. Still only showing 1WU per GPU. This is what I have for the app_config.xml <app_config> <app> <name>astropulse_v7</name> <gpu_versions> <gpu_usage>.33</gpu_usage> <cpu_usage>.67</cpu_usage> </gpu_versions> </app> <app> <name>setiathome_v8</name> <gpu_versions> <gpu_usage>.33</gpu_usage> <cpu_usage>.075</cpu_usage> </gpu_versions> </app> </app_config> Also just to clarify, all GPU's are working on it, just a single task each rather than 2-3 which is what I'm after. |

Where did you put the cc_config.xml file? It needs to be in the BOINC data directory, default at C:\Programdata\BOINC\ Make sure the file is called cc_config.xml, not that it got an extra extension. Hope you made it with Notepad, as making it with any other text editor will add invisible characters that BOINC won't like. A very easy way to get a fully populated cc_config.xml file in the right place is to open BOINC Manager->Advanced view->Options->Event Log options...->uncheck task->OK. Do enable task again after this, BOINC Manager->Advanced view->Options->Event Log options...->check task->OK. You have to restart both the BOINC Manager (GUI) and the client, as GPU detection decisions are only done at BOINC (client) startup. The app_config.xml file also needs to be written in Notepad and not any other text editor, as those add invisible characters BOINC doesn't like. It is stored in C:\Programdata\BOINC\projects\setiathome.berkeley.edu\ When writing or editing XML files in Notepad, save them as follows, i.e. app_config.xml: File->Save as..->Filename app_config.xml ->save as type: All files (*.*) ->Encoding ANSI |

Okay, added the CC_Config.xml file Might try upping the CPU to say: <cpu_usage>0.33</cpu_usage> Don't forget all the restart stuff as well as confirming that your parameter files are located in the right subdirectories. A proud member of the OFA (Old Farts Association). |

...and with the current crop of work 0.33 GPU is probably "too enthusiastic" - even on a GTX1080 - start at 0.5 and see what the system does. Using the Intel GPU with two external GPU is probably going to be counter productive, especially if yo try to run multiple tasks on it.

I think I may have just found the root of my problems. It's saving as app_config.xml.txt I've saved it as an all other files under ansi as well, however when I go to save it again it asks if you want to replace app_config.xml.txt How do I get it to stop adding the extra file extension? I'm kinda new to this, so sorry for any facepalm moments! Also thank-you all for the solid and helpful replies so far! |

Scratch that! I've had success and managed to get the XML file to save without the extra extension. Boinc is now running 2 WU across all the GPUS |

I know you fixed it already, this is just for the next person with the same problem: app_config.xml.txtRight-click on the file name, from the drop-down menu choose Rename. Scroll to the end of the line, use backspace four times to remove the dot tee ex tee (.txt), and finish with Enter. |
