What about the AMD way? ie. each cpu having direct access to separated RAM banks and doing some sort of transaction making it basically a NUMA architecture wich act externally as SMP. (I may be wrong about that, but that's what I got from reading some specs of Athlon X2) I'm just wondering the implications, not even suggesting as a real implementation idea. :)
NUMA relies on different CPUs having different working sets. In the graphics case, the most heavily drawn-to part of memory is the same as the most heavily-scanned-for-video. So we can't separate video out. We might be able to do some things like put textures and z buffer in one place and video buffer in another. The problem is that with X11, pixmaps are used so heavily that they are accessed as much as the video buffer. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
