I don't know if I'll get enough information to do this, but if it's possible, I'll do my best to write a guide so even people who don't know much about programming will be able to construct their own app_info.xml file and install it from a basic template.
----------------------------------------Considering how clueless I am right now that might be a pipe dream, but if you stare at it long enough, the xml stuff isn't really that scary. Maybe I'm delusional but I think I just need a little more basic information.   [Edit 1 times, last edit by twilyth at Nov 12, 2012 4:30:44 AM] |

You are doing OK. Just take it slow and re-read app_info thread a couple times. It will sink in. You have a six cores CPU and a radeon 6850 video card. I see from your badges that you have suupported most research projects. Remember that you can only use your 6850 to process ati_hcc v7.05 WUs for Help Conquer Cancer. if you want to maximize you productivity you have to restrict your rig to Help Conquer Cancer WUs.
----------------------------------------WHat is your aim? What Do you want to achieve? Is your CPU overclocked? What MHz is it running at?

If you have read the thread and understand it perhaps you could answer some of my questions?

I read your thread and I cannot determine what it is that you are asking or what it is that you want to achieve. Here are the options for you:
----------------------------------------1- Process 6 CPU WUs 2- Process concurrently (1 x ATI hcc GPU using 1 CPU thread ) + run 5 x other CPU Wus) no app info needed for that with App _info. 3- Process (2 x 0.5 ATI_hcc GPUs using 2 CPU thread) + run 4 other CPU WUs 4- Process (3 x 0.33 ATI_hcc GPUs using 3 CPU thread) + run 3 other CPU WUs 5- Process (4 x 0.25 ATI_hcc GPUs using 4 CPU thread) + run 2 other CPU WUs 6- Process (5 x 0.20 ATI_hcc GPUs using 5 CPU thread) + run 1 other CPU WUs 7- Process (6 x 0.166 ATI_hcc GPUs using 6 CPU thread) Option 6 & 7 may not be available to you. Normally start with # 3 and work up while monitoring your % of GPU use and temperature. In summary app_info sub-divides your GPU. Those sub-divided GPU units are then associated with an available CPU core/thread. ATI/AMD cards only work with HCC GPU files. Left over CPU cores/threads (if any) can be assigned to any other WCG project. Hope that this clarifies things a bit for you.

That was one of the few parts I was able to figure out actually, but thank you.

Just a general comment to app_info and reading somewhere a 10 step procedure with a certain emphasis of not removing, whilst. Has anybody actually ever looked at the file ownership and permissions of the app_info.xml ? Certainly have never seen it mentioned, where for sure what's in the projects folder does have a consistent set of what group owns and groups that have access [boinc_admins , boinc_users , boinc_projects]. At least on my systems that's 100% consistent. Can't see if only joe_cruncher has rights [the one who put the file there], how boinc user groups can have access to the file or it's contents.
----------------------------------------errata: Pulled from the official BOINC wiki: Create a file app_info.xml in the project directory. ... inside the Mac's BOINC Data directory, you must set ownership and permissions properly. Why would that not apply to Windows or Linux either? edit: Did some testing on a dummy app_info file placed in projects\www.worldcommunitygrid.org and find that certainly on W7 and W8, the group permissions are inherited from the folder settings i.e. the file got the same rights/permissions as the other files in the projects folder. This is Windows 7/8. For Linux to test and for Mac in B&W. Be aware when HCC-GPU comes to latter platform. [Edit 1 times, last edit by Former Member at Nov 12, 2012 8:32:43 AM] |

Why would that not apply to Windows or Linux either? Can't say for Linux, but atleast for Windows, since GPU-crunching only works for non-service installations (*), BOINC will run as the logged-in user, meaning the logged-in user has access to all the files in the BOINC-data-directory (or BOINC refuses to run at all since have no access at all). If the logged-in user makes/edits an app_info.xml file BOINC will also have access to this file. (*): Well, if you're running the ancient Windows-XP and an ancient BOINC-client, and somehow manages to find a graphics-card-driver not crashing BOINC, it is possible to install as a service and still crunch on your GPU. A quick look on BoincTask reveals only 10.5% of RAC is now from XP-computers and an additional 1.1% from win2003, so for most GPU-crunchers service-installation isn't an option.

Thought to bring this up, and point as the Mac (Possibly Linux) requirement as well. If not relevant to Windows [user install], great.

I don't want to seem rude and I'm all in favor of getting as much information about these beasties out there as possible, but for the moment, I would very much appreciate it if someone could provide answers to the questions I have posed. I can restate those if it will help condense and focus the discussion.

I can restate those if it will help condense and focus the discussion. Atleast one problem you'll hit is with: <platform>windows_x86_64</platform> Since WCG's scheduling-server doesn't correctly handle anonymous platform, it will only issue work for platform windows_intelx86 so you'll need to change this (including both is possible). As long as you're running a 64-bit OS it's no problem you'll still using the 64-bit application. Since you haven't posted any system-info appart for GPU & CPU, XP is a large source of problems while another is if you're not running a BOINC-v7-client. If you're still running v6, upgrade ASAP to atleast v7.0.28 but at the moment v7.0.36 seems to be the best. "I make so many mistakes.
