Matrix transpose on meshes: theory and practice
Michael Kaufmann, Ulrich Meyer, Jop F. Sibeyn · 2002
Matrix transpose is a fundamental communication operation which is not dealt with optimally by general purpose routing schemes. For two dimensional meshes, the first optimal routing schedule is given. The strategy is simple enough to be implemented, but details of the available hardware are not favorable. However, alternative algorithms, designed along the same lines, give an improvement on the Intel Paragon.
