This book was released on 1988 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report covers the period from October 1, 1987 through September 30, 1988, the first year under the contract. The objective of this effort is to define and evaluate new approaches to two-dimensional arrays of reconfigurable optical interconnections for optical computing. The emphasis is on optically controlled optical beam directors or switches which can be fabricated into high density 2-D arrays. The proposed applications in optical neural computers and other types of optical computers require reconfiguration speeds on the order of microseconds. The emphasis is therefore on devices and nonlinear optical materials with response times of microseconds but with the potential for high packing density. The approach to this research has two components: i. nonlinear optical materials; and ii. optically controlled optical switching devices which can be integrated into 2-D arrays. The materials work stresses the transport assisted optical nonlinear materials since this is the only class of materials which exhibit a sufficiently large nonlinearity, in the response time required, and with a relatively low optical energy required. In these materials, optically excited electric charge is separated by an electric field to create a space charge field which reduces the total electric field. (RH).

Download or read book Novel Optical Computer Architecture Utilizing Reconfigurable Interconnects written by and published by . This book was released on 1991 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This final report describes progress made by TIS Incorporated for the period 7/1/91 - 10/1/91 toward the development of novel optical computer architectures and supporting methods for exploiting free-space reconfigurable interconnects. Major findings include: (1) Reconfigurable interconnects can reconfigure slower than the bit rate and still improve performance as long as throughput is maintained after reconfiguration; (2) A fixed control sequence does not preclude the use of runtime conditionals, so that the performance of traditional general purpose computing can be improved; (3) A system that uses reconfigurable interconnects is likely to be larger than a functionally equivalent system that does not use reconfigurable interconnects; (4) A reconfigurable approach is most effective for a small active portion of a computer, and is not needed for an entire computer in order to appreciate a performance gain; (5) A reconfigurable interconnect technology can have a significant impact on interconnection networks used in parallel processors; (6) A fixed control sequence must have some level of repetition in order to be practical; and (7) The dataflow model of computing, which theoretically supports maximum parallelism but suffers performance sacrifices in electronic implementations, may be significantly improved since the architecture can be modified to suit the dataflow graph.

Book Synopsis A 4x4 Photorefractive Reconfigurable Interconnect Using Laser Diodes by : Arthur E. Chiou
Download or read book A 4x4 Photorefractive Reconfigurable Interconnect Using Laser Diodes written by Arthur E. Chiou and published by . This book was released on 1992 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reconfigurable optical interconnection capable of partial or full broadcasting plays a key role in optical computing and optical neural network. The interconnection can be implemented using optical matrix-vector multiplication. The reconfigurability is achieved by changing the interconnection matrix written on a spatial light modulator (SLM). For a one-to-one permutation link of an array of N detectors, such an approach suffers a 1/N intrinsic fanout loss. In this paper, we report the demonstration and characterization of a 4x4 reconfigurable interconnection using two laser diodes (780nm) and a ferroelectric liquid crystal spatial light modulator (FLCSLM) in conjunction with a photorefractive barium titanate crystal. Specifically, we compare the energy efficiency and crosstalk of this new approach with those of the conventional approach.

This book was released on 2012-12-06 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conference "Nonlinear Optics and Optical Computing" was held May 11-19, 1988 in Erice, Sicily. This was the 13th conference organized by the International School of Quantum Electronics, under the auspices of the "Ettore Majorana" Center for Scientific Culture. This volume contains both the invited and contributed papers presented at the conference, providing tutorial background, the latest research results, and future directions for the devices, structures and architectures of optical computing. The invention of the transistor and the integrated circuit were followed by an explosion of application as ever faster and more complex microelectronics chips became available. The information revolution occa sioned by digital computers and optical communications is now reaching the limits of silicon semiconductor technology, but the demand for faster com putation is still accelerating. The fundamental limitations of information processing today derive from the performance and cost of three technical factors: speed, density, and software. Optical computation offers the potential for improvements in all three of these critical areas: Speed is provided by the transmission of impulses at optical veloc ities, without the delays caused by parasitic capacitance in the case of conventional electrical interconnects. Speed can also be achieved through the massive parallelism characteristic of many optical computing architec tures; Density can be provided in optical computers in two ways: by high spatial resolution, on the order of wavelengths of light, and by computa tion or interconnection in three dimensions.

Book Synopsis Randomization Methods in Algorithm Design by : Panos M. Pardalos
Download or read book Randomization Methods in Algorithm Design written by Panos M. Pardalos and published by American Mathematical Soc.. This book was released on with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on proceedings held during the DIMACS workshop on Randomization Methods in Algorithm Design in December 1997 at Princeton. The workshop was part of the DIMACS Special Year on Discrete Probability. It served as an interdisciplinary research workshop that brought together a mix of leading theorists, algorithmists and practitioners working in the theory and implementation aspects of algorithms involving randomization. Randomization has played an important role in the design of both sequential and parallel algorithms. The last decade has witnessed tremendous growth in the area of randomized algorithms. During this period, randomized algorithms went from being a tool in computational number theory to finding widespread applications in many problem domains. Major topics covered include randomization techniques for linear and integer programming problems, randomization in the design of approximate algorithms for combinatorial problems, randomization in parallel and distributed algorithms, practical implementation of randomized algorithms, de-randomization issues, and pseudo-random generators. This volume focuses on theory and implementation aspects of algorithms involving randomization. It would be suitable as a graduate or advanced graduate text.

Book Synopsis RAPID: Reconfigurable All-Photonic Interconnect for Parallel and Distributed Computers by : Avinash Karanth Kodi
Download or read book RAPID: Reconfigurable All-Photonic Interconnect for Parallel and Distributed Computers written by Avinash Karanth Kodi and published by . This book was released on 2006 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relentless quest for processing speeds in the range of Teraflops and beyond has accelerated the need for scalable, parallel, High-Performance Computing (HPC) systems. For these systems to be scalable and attain the desirable performance, the interconnection network connecting the processors, must itself be scalable in both size and bandwidth. However, at higher bit rates and longer communication distances, fundamental electrical signaling limitations reduce the inter-processor communication bandwidth while increasing the power dissipation, thereby affecting not only the performance of HPC systems, but also their scalability. In this dissertation, we propose an optical interconnect based architecture for HPC systems called RAPID (Reconfigurable All Photonic Interconnect for Distributed and parallel systems) that maximizes the bandwidth density, optimizes power consumption and enhances scalability using static wavelength allocation. We also present two cost-effective design alternatives of the architecture, a modified version called M-RAPID and an extended version called E-RAPID that minimizes the cost of the interconnect based on the number of transmitters required. In addition, we propose a detailed implementation and integration methodology of RAPID using current complimentary-metal-oxide-semiconductor (CMOS) technology. In order to develop a flexible interconnection architecture, we provide dynamic system reconfiguration that further reduces the communication bottlenecks and achieves better resource utilization. Reconfigurability is realized by monitoring traffic intensities, and implementing dynamic bandwidth re-allocation (DBR) techniques that adapt to changes in communication patterns. A DBR technique - Lock-Step (LS) that balances the load on each communication channel based on past utilization is also presented. While computer-aided design (CAD) toolshave significantly assisted electronic system simulation, the field of system level opto-electronics modeling has lagged behind due to lack of simulation methodologies and tools. We present the design space of developing OPTISIM, a system level modeling and simulation methodology of optical interconnects for HPC systems. Using OPTISIM, we performed detailed simulation of RAPID architectures and compared it to several electrical HPC interconnects using synthetic traffic patterns. Simulation results indicate that the reconfigured architecture shows 35% increased throughput and 20% reduced network latency as compared to HPC electrical networks.
