Dear all, I'm trying to render a town with 2 graphic cards in the same computer: i7-3770 (quad core with hyper-threading = 8 cores virtual), 2x gtx780ti, xubuntu 12.04, OSG3.2.0.
A separate X server run on each card and there is only one monitor(screen) attach to each card. So I run the application twice (one per X server) with separate graphical context and "DrawThreadPerContext" threading model. I monitor cpu core usage with "sar" command (from sysstat package). The system sees 8 cores as expected. The two "Application+cull" threads are running on two separate cores (that's nice) but the two "draw" threads are allways running on the same core resulting in a lack of performance... Have you got any idea to solve this trouble ? Thank you!
