Does anyone know if it is possible to configure App_Info.xml to run a different number of WUs on different cards? For instance. I want to run 4 WUs on my HD7750 and 8 WUs on a HD7850 or something. Is that possible or do you have to run the same # on all cards?
Thanks! |

I don't know if there is a way to do that with one app_info file. I would imagine, with a little tweaking, you could run two instances of BOINC from different directories and have cc_config set to use a specific card and a separate app_info for each instance of BOINC.

Yes, on the same machine.

That is an interesting solution, that just might work. |

Hello pandelta,
I believe that Dr. Anderson intends that the future app_config.xml file will enforce a rule for all GPUs on a system to run the same number of GPU work units. Reason - simplicity of programming. Naturally, the future is subject to change. But . . . Lawrence |

Hello pandelta and welcome to WCG.
I must say, your query about the possibility of running a different number of GPU-WUs on different cards -- is a bit too far ahead of the curve. I would find it interesting to see how the demand for such feature would play out to influence BOINC as GPU-computing evolves. ; ; andzgridPost#731 ; |
