Optical Multi-Tree with Shuffle Exchange

An optoelectronic system is basically a hybrid system that exploits both the advantages of <a href="/facts/Electronic_communication/vxoj1cxR">electronic</a> and <a href="/facts/Optical_communication/gshoNBto">optical communication</a>. Various models of optoelectronic <a href="/facts/Parallel_computers/nQzcpzQt">parallel computers</a> have been proposed in recent years. Optical Multi-Trees with Shuffle Exchange (OMTSE) using both electronic and optical links among processors. The processors are organized in the form of an n × n <a href="/facts/Vector_processor/nYAsIKT0">array</a> of certain groups each containing 3n/2 <a href="/facts/Node_(networking)/LBp2vNcJ">nodes</a>. It can be noted that the entire <a href="/facts/Network_topology/rBYE0kke">network topology</a> is almost regular with an O(log n) diameter.
For <a href="/facts/Parallel_computing/nQzcpzQt">parallel computing</a>, the interconnection network is the heart of a parallel processing system, and many systems have failed to meet their design goals for the design of their essential components. The <a href="/facts/Bandwidth_(signal_processing)/7eMDzfJI">bandwidth</a> limitation of the electronic interconnects prompted the need for exploring alternatives that overcome this limitation. Optics is considered as an alternative that is capable of providing <a href="/facts/Inherent/FjJrbzGh">inherent</a><a href="/facts/Communication/EGEkchsT">communication</a>, parallelism, high connectivity and large bandwidth. When the communication distances exceed a few millimeters, optical interconnects provide advantage over the electronic interconnects in term of <a href="/facts/Electric_power/w61ID9yQ">power</a>, <a href="/facts/Speed/I3qgMPfs">speed</a> and <a href="/facts/Crosstalk/IT2LIwth">crosstalk</a> property. Therefore, in the construction of very powerful and large <a href="/facts/Multiprocessor/aDCfehDQ">multiprocessor</a> systems, it is advantageous to interconnect close processors physically using electronic links and far processors (kept in other package) using optical links. Thus we use optical network like <a href="/facts/OMTSE/j8EvhXGR">OMTSE</a>, OTIS, and OMULT etc. The OMTSE network consists of two different systems called as optical and electrical. In this network there are using two layer of TSE network with a complete <a href="/facts/Binary_tree/TDV7GMpu">binary trees</a> of height one and the roots of these binary trees are connected with <a href="/facts/Shuffle-exchange_network/vcYyHlgo">Shuffle-Exchange</a> fashion.
