Contiguous dimension of the tile shape matches one shared memory cache line - 128B. For 128bit access size, it equals to 8 accesses.

 | static | 
The strided dimension needs to be at least WarpSize(32) / kTileShapeContiguous for a warp to access. To ensure conflict free access, it also needs to be at least (kTileShapeContiguous / kFactor).
