use arrays instead of textures for general storage on this card (image textures are still stored as texture). Textures were found to be faster on older cards, but the limits on 1D texture size have not increased along with the memory size, which meant that the full 6 GB could not be used. The performance actually seems to be slightly better with arrays in some tests on Titan. For older cards there seems to be a bit of a mix, some are better and others not. We may change those to use arrays too, but more testing is needed, only Titan and Tesla K20 (sm_35) is changed for now. The fact that arrays are faster is a bit surprising, as others found textures to be faster on Kepler. However even if they were, the memory limitation is more important to solve anyway. https://research.nvidia.com/publication/understanding-efficiency-ray-traversal-gpus-kepler-and-fermi-addendum |
