Optical Multi-Trees with Shuffle Exchange (OMTSE), recently proposed, is an efficient model of optoelectronic parallel computer. The OMTSE interconnection system consists of n factor networks called TSE networks, which are organized in the form of an n× n matrix. Each factor network has n number of leaf nodes. The network has a total of 3n/2 nodes. The(More)
Protein structure comparison has long been under investigation by computational biologists in hopes for finding a better but not necessarily faster alternative to the more familiar multiple sequence alignment problem. The multiple alignment problem is more challenging than pairwise alignment even for sequences, and we resort to heuristics to find as best an(More)
Optical Multi-Trees with Shuffle Exchange (OMTSE) architecture is an efficient model of an optoelectronic computer. The network has a total of 3n/2 nodes. The diameter and bisection width of the network are 6 logn − 1 and n/4 respectively. In this note, we present synchronous SIMD algorithms on an OMTSE optoelectronic computer for the following problems in(More)
