To avoid wasting a LOT of idle GPU time for HCC, running multiple GPU tasks at the same time is the way to go. To do that, you need to employ the anonymous platform feature of BOINC. Fair enough. I've seen app_info.xml files posted that we can copy to MAKE IT SO.
The problem is that using an app_info.xml file that includes entries for only HCC GPU tasks, excludes everything else. It would be great if someone who understands all the ins and outs of the app_info.xml (that excludes me), if they could post an app_info.xml that included ALL active projects, all apps. Then we users could strip out the projects we don't want to participate in, and the applications that don't fit the particular machine (win/lin/osx, 32/64 bit, etc.). Any takers? |

LOL, I was actually about to create a thread with the exact same question right now. So thanks for taking that off my hands...
---------------------------------------- My graphics card (HD7770) is idling for most of the time so I also would like to be able to run multiple tasks without having to give up on the CPU projects. Any input would be highly appreciated.   |

Thanks! I see I've got some testing to do!

If your 7770 is idling most of the time and you have been using it to run the WCG GPU app there is something wrong with your settings.

Waiting for a HCC GPU + HFCC app_info...no one?

@flodisar, I tried using the HCC GPU + HCC app_info from the XS forum, but I couldn't get it to work. I just got a bunch of error messages and BOINC telling that it didn't need to download new files. So I have to see if I did something wrong. About HFCC, jspace at the XS forum said he's working on this app_info. Maybe he can help out?
----------------------------------------If your 7770 is idling most of the time and you have been using it to run the WCG GPU app there is something wrong with your settings. OK, are there any settings I can change to improve this? I didn't change anything exept for the one to make the GPU crunch while the PC is in use. It is now set to do GPU work all the time. I'll try to describe the situation. When I have a HCC GPU workunit, the CPU uses about 30 seconds before the GPU 'kicks in'. The GPU then completes the workunit in a little under a minute and then the CPU has to finish the workunit for another minute. So roughly said the GPU is used for about 1 minute and is idling for about 1:30 minute because it's waiting for the CPU starting and finishing the workunit. And when the GPU is in use, the load never exceeds 85%. Any toughts on what I can do to improve the load and have less idling time? It's an old i7-920 using 8 threads, and I really would like to use the remaining threads for CPU work... [Edit 1 times, last edit by depriens at Nov 2, 2012 8:48:05 PM] |

To maximize what you're GPU is doing, the easiest way is to adjust the <count></count> setting. Using <count>.125</count> in the app_info will run 8 concurrent GPU WUs. That should keep the GPU busy nearly 100% of the time and be more productive (at least as far as HCC is concerned) than running GPU+CPU. IMHO, if you're interested only in HCC and have a capable GPU, running as many GPU WUs as possible is the way to go. |

Which brings us back to the original request, of a working app_info.xml, that includes everything. Then we can just strip out the unwanted CPU projects. |

I guess I got sidetracked by the "I tried using the HCC GPU + HCC app_info" part.
