Can anyone running 2 GPUs or a GPU and another graphics card for displaying post their SDK bandwidth results for pinned and pageable memory copy?
I have observed that if I use a single 8800GTS I get a significant speedup from using pinned host memory, as expected. However, if I enable a secondary graphics card, in this case a FX550, I stop getting any significant benefit from pinning. Has anyone observed any similar effect?
I am using the 184.108.40.20675 drivers on both cards.
