Hi people, after reading this thread I must admit to some confusion so here is my issue.
----------------------------------------I have an Intel i7 975 CPU. It has 8 threads running. I have a NVIDIA GeForce GTX 285 GPU. My WCG BOINC Manager shows one CPU thread working with one GPU. How do you get multiple threads working out of one card? Or am I miss reading something. P.S. I am working on installing a second GPU card. Same model as the original card. What modifications do I need to make to bring the new card into the fold? Thanks for the guidance.   O/S -LinuxMint 64-bit, Release 13 (maya).

Hello Gandalf_PCHF,
Right now, a GPU can only run 1 task unless you go to the trouble of creating a special app_info.xml file, which is not supported by WCG. So that is what you want to search for to locate the threads in which people discuss how-to. Better search for GTX285 as well since OpenCL drivers for Nvidia tend to be less capable than for ATI GPUs. Lawrence |

Gandalf,
----------------------------------------Also note that NVIDIA GPUs need a full core from the CPU per unit. Well, my 285s started to error with just 2 units now. Back to one at a time.  [Edit 1 times, last edit by Former Member at Dec 2, 2012 9:00:30 PM] |

I now have both GPUs installed, however WCG is only recognizing one of them. How do I get the WCG software to recognize and start using the second GPU?

Gandalf, Also note that NVIDIA GPUs need a full core from the CPU per unit. rjbelans - That is not the case with my system. I have 8 threads and only one is needed to use my GPU. The other 7 are used for CPU tasks. Reference included link... http://i702.photobucket.com/albums/ww27/Gandalf_PCHF/CPUGPU.jpg Please note - there is only one GPU being used not two.

Add the following to your cc_config.xml file. <use_all_gpus>1</use_all_gpus> If you don't have a cc_config.xml file in the BOINC folder then copy what's below into notepad. Rename the file cc_config.xml and place it into the BOINC folder. (Just an FYI if don't already know the BOINC folder is hidden by default in Windows. You'll have to set your OS to show them to get to the right folder. In Win7 it's MyComputer>C/Drive>ProgramData>BOINC) <cc_config> <options> <use_all_gpus>1</use_all_gpus> </options> </cc_config>

nanoprobe - you are a Master indeed. I understood what you wrote and it worked. I now have both GPUs working. My team captain will blow his mind when he sees my results next week.
