Run Multiple WU's on a Single GPU

Having problems installing that new stick of memory? Found some great software or having issues with something? Or maybe want to chat about your PlayStation, X-Box, Nintendo, Sega, even your old Spectrum 48k....! Or maybe something you want to sell or acquire (computing related of course!). Let us know here...

Run Multiple WU's on a Single GPU

Post by Timby »

Hi all, just been trying out a few mods for my machines, been researching running multiple WU's on my GPU's and could not see any reference on our forum to this.
I thought a brief out line of the subject may inspire one or two to try this out?
(I will not be held responsible in any way shape or form if you break you machine or GPU)

OK I have two PC's, one fitted with a Nvidia GPU and the second with two ATi GPU's. I used an auto installer for one and wrote an "app_config.xml" for the other, both function perfectly.
To do this manually open note pad and copy the script from here http://boinc.berkeley.edu/trac/wiki/ClientAppConfig

This is the Nvidia app_config file content:

<app_config>
  <app>
     <name>hcc1</name>
     <max_concurrent>2</max_concurrent>
     <gpu_versions>
         <gpu_usage>.25</gpu_usage>
         <cpu_usage>.1</cpu_usage>
     </gpu_versions>
  </app>
</app_config>


<name>hcc1</name>  =  WU
<max_concurrent>2</max_concurrent>  =  Number of WU to run on the GPU.

This works perfectly on my PC's, you must have the latest BM (7.0.42) running that supports the xml files, run time for each WU is exactly the same as when running a single WU.

Hope this is of use, there is loads of Internet articles on this subject, far too many for me to list, but in essence seems to be producing good results for myself. Once all my WGU have gone I will try Poem WU!!
