Lab 5 ● ● ● ● Organize your volume cube with threads running in the lowest dimension and a 2D grid for the other 2 dimensions to make indexing easier See globally defined dim3s The space extends in ±2.0 in each direction (for converting indices to positions) 1 thread per element is probably fastest, but feel free to experiment with loops
Memory Coalescing ● If you compute the index within the block as: – i = x + width*y + width*height*z – then write to output[i] – threads run along x, therefore coalesced ● ● Non-coalesced case: x swapped with one of the other dimensions Test both coalesced and non-coalesced speeds, write results into README
