NVIDIA Tesla D870+ AMD Athlon Dual Core 4400+, Fedora 7
I used 44 tiled, 88 tiled, 1212 tiled and 1616 tiled.
I just tested the CUDA Occupancy using CUDA Occupancy calculator and get the following results. 88 tiled and 1616 tiled both have the same occupancy 67%. Occupancy can affect the effect of different tile size? I don’t understand how to choose tile size in terms of occupancy.
