Book Description
Parallel Sorting Algorithms explains how to use parallel algorithms to sort a sequence of items on a variety of parallel computers. The book reviews the sorting problem, the parallel models of computation, parallel algorithms, and the lower bounds on the parallel sorting problems. The text also presents twenty different algorithms, such as linear arrays, mesh-connected computers, cube-connected computers. Another example where algorithm can be applied is on the shared-memory SIMD (single instruction stream multiple data stream) computers in which the whole sequence to be sorted can fit in the respective primary memories of the computers (random access memory), or in a single shared memory. SIMD processors communicate through an interconnection network or the processors communicate through a common and shared memory. The text also investigates the case of external sorting in which the sequence to be sorted is bigger than the available primary memory. In this case, the algorithms used in external sorting is very similar to those used to describe internal sorting, that is, when the sequence can fit in the primary memory, The book explains that an algorithm can reach its optimum possible operating time for sorting when it is running on a particular set of architecture, depending on a constant multiplicative factor. The text is suitable for computer engineers and scientists interested in parallel algorithms.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Description
This concise text is designed to present the recent advances in parallel and distributed architectures and algorithms within an integrated framework. Beginning with an introduction to the basic concepts, the book goes on discussing the basic methods of parallelism exploitation in computation through vector processing, super scalar and VLIW processing, array processing, associative processing, systolic algorithms, and dataflow computation. After introducing interconnection networks, it discusses parallel algorithms for sorting, Fourier transform, matrix algebra, and graph theory. The second part focuses on basics and selected theoretical issues of distributed processing. Architectures and algorithms have been dealt in an integrated way throughout the book. The last chapter focuses on the different paradigms and issues of high performance computing making the reading more interesting. This book is meant for the senior level undergraduate and postgraduate students of computer science and engineering, and information technology. The book is also useful for the postgraduate students of computer science and computer application.

Book Description
This thesis is concerned with the development of a unique parallel sort-merge system suitable for implementation in VLSI. Two new sorting subsystems, a high performance VLSI sorter and a four-way merger, were also realized during the development process. In addition, the analysis of several existing parallel sorting architectures and algorithms was carried out. Algorithmic time complexity, VLSI processor performance, and chip area requirements for the existing sorting systems were evaluated. The rebound sorting algorithm was determined to be the most efficient among those considered. The rebound sorter algorithm was implemented in hardware as a systolic array with external expansion capability. The second phase of the research involved analyzing several parallel merge algorithms and their buffer management schemes. The dominant considerations for this phase of the research were the achievement of minimum VLSI chip area, design complexity, and logic delay. It was determined that the proposed merger architecture could be implemented in several ways. Selecting the appropriate microarchitecture for the merger, given the constraints of chip area and performance, was the major problem. The tradeoffs associated with this process are outlined. Finally, a pipelined sort-merge system was implemented in VLSI by combining a rebound sorter and a four-way merger on a single chip. The final chip size was 416 mils by 432 mils. Two micron CMOS technology was utilized in this chip realization. An overall throughput rate of 10M bytes/sec was achieved. The prototype system developed is capable of sorting thirty two 2-byte keys during each merge phase. If extended, this system is capable of economically sorting files of 100M bytes or more in size. In order to sort larger files, this design should be incorporated in a disk-based sort-merge system. A simplified disk I/O access model for such a system was studied. In this study the sort-merge system was assumed to be part of a disk controller subsystem.
