needs fast access to neighboring data, rather than elements in a row, or must transverse the data multiple times? • To improve data locality of multi-dimensional data, using a Morton ordering, can help implementation can result in up to 11 times the performance on the Intel Xeon Phi coprocessor. When using multiple threads (which the Intel Xeon Phi is designed for), using the Morton ordering, performance is up
