Abstract

In optoelectronic OTIS multicomputer networks (also known as Swapped networks), electrical and optical interconnects are used for local and global communication, respectively. An interesting instance of the OTIS multicomputers is the OTIS-mesh. Pancyclicity is of great importance in the implementation of a variety of parallel algorithms in multicomputers. This paper addresses the Pancyclicity problem of OTIS-mesh. More precisely, we prove that if the factor graph G of an OTIS network is a 2-D or 3-D mesh with at least one even radix, OTIS-G can embed any cycle of length l, l@?{4,6,7,8,9,...,|G|^2}.
