So,l to clear up: the fact you can run 4 windows doesn't mean it uses the separate GPUs. 4 windows are 4 different windows, but if you want to address different GPUs, you need to run one of the 2-pipe.*.eqc-config files. This means: The input of 1 windows is computed by different GPUs. If you want to have different windows pumped with information by different GPUs, you have to write an own config ... soemthing like 4-window-2-pipe, while always 2 windows get pumped by 1 GPU.
Therefore, it is not a problem to run an application with multiple windows. you can also run 16 windows on 1 GPU, although you have then horrible fps. You should first try to run a 2-pipe config. Although I am sure it will fuck up then in release and build, because your equalizer can't address the second GPU for the second part of the screen. This is because the loss of support of the basic OpenGL-function for consumer cards. And this is not done or controllable by the little cross in the NVIDIA Control Panel. No matter of having the cross there or not, you are always physically using SLI, because the tiny bridge for multiple NVIDIA cards is named like that. The only difference is if you also logically use SLI as a controlled function of the Control Center, or if you are programming the distribution for the SLI-Bus by OpenGL extension, respective Equalizer. So, unfortunately, with normal Graphics Libraries you are normally not able to address specific GPUs in consumer solutions. Your hope/new way can be the GPGPU interfaces. There, it is possible for all cards to address specific cards of Multi-GPU configurations. Perhaps you could use the fact that you can differentiate between the cards in OpenCL and use it's OpenGL connection. Would be an option to implement as a consumer solution in the, beside this bad effect, wonderful Equalizer. Perhaps you talk about that later with Stefan. First: Try to run 2-pipe-config ;-) -------- Original-Nachricht -------- > Datum: Wed, 10 Mar 2010 17:19:37 +0100 > Von: Raymond de Vries <[email protected]> > An: [email protected] > Betreff: Re: [eq-dev] Dependancies for building with VS2008? > Hi Chris, > > Thanks for your mail, there's a lot of info in it.
