using this ordering, for example in a 16 x 16 matrix, each of the 4 sub matrices can fit into a single cache line. For example, when transposing a simple matrix, if each of the sub-matrices are transposed transposed themselves, then transposing the 4 x 4 matrices will lead to the full matrix transpose. When dealing with large matrices (1024 x 1024 and larger), speedups by using a Morton ordering compared to a is designed for), using the Morton ordering, performance is up to 2.44 times faster for a large matrix transpose. Even on an Intel Xeon CPU, by using up to 32 threads, comparing the naïve implementation
