With reference to nanoprobe's post https://secure.worldcommunitygrid.org/forums/wcg/viewpostinthread?post=402731. I'd like to try to add CPU processing to a machine already doing GPU. I think I'm starting to understand app_info.xml more now. Because there are no CPU units in my folder, when I swap my old version with the new version that refers to CPU tasks, I get the message
----------------------------------------File referenced in app_info.xml does not exist: wcg_hcc1_img_7.05_windows_intelx86 So what I did was
When I restarted without an app_info.xml, I managed to download CPU units and they started to process, however when I stopped and introduced the new app_info.xml and restarted, I got messages like [error] No application found for task: windows_intelx86 705 ; discarding [error] State file error: result X0000133721100201204121431_1 not found for task and CPU units are no longer processed.

@KerSamson, nanoprobe, If I'm not mistaken, the problem is the Windows XP Pro SP3 x32. I have the XP Pro X64bit and have never been able to get more than 1 per GPU card working That's a good point. ATI driver support for OpenCL on XP stopped a while back so that could be the problem. Try here: http://www.hal6000.com/seti/boinc_ati_gpu_cheat_sheet.htm   |

Very not likely, simple because the client / server structure to do so does not exist Einstein@home already has the option for users to specify #task per GPU, without using app_info.xml at all... So, if WCG wants to do something similar, it's just to talk to Einstein@home. The NEW version of the Boinc Server Software let's you do it thru a cc_config.xml file. I don't know what version WCG is using but suspect it might be a pain to upgrade due to all the heavy mods they have done. MOST projects modify the server software for various reasons. |

I have had to be very quick with my mouse to suspend EAH after hard reboot during CPU benchmark. Otherwise, mac has kept freezing. No, thank you. ALOT of people are having that problem, freezing during benchmarking, and have turned it off as a result. It is a switch in either the cc_config or the app_info file. |

When you use an app_info file the default settings are no longer valid, so you must specify EVERYTHING you want it to do or it won't. One of the groups a week or two ago had a LONG app_info file to run each project, both the cpu and gpu ones but I do not remember where it was.

OK, I thought that
----------------------------------------<file_info> <name>wcg_hcc1_img_7.05_windows_intelx86</name> <executable/> </file_info> would be enough. After reading the link and PDF file, I'm even more confused...  Crunching in memory of my Mum PEGGY, cousin ROPPA and Aunt AUDREY. |

I believe I have an app_info that will let you run HCC GPU and CPU tasks simultaneously but I'm at work and don't have access to it. I can post it when I get home if you're interested.

Where do I find <app_info> and <file_info>? I do not know what directory these are in. When I was using XT, there was an option with the start button that let you do a find for file names when you used a right-click with the mouse. I am now using Windows 7.

These files are not part of any OS directory. They are created for a specific project and then placed in the project folder.
