This book was released on 1992 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Database programming languages like O2, E, and O++ include the ability to iterate through a set. Nested iterators can be used to express joins. Without program analysis, such joins must be evaluated using a tuple-at-a-time nested-loops join algorithm, because otherwise program semantics may be violated. Ensuring that the program's semantics are preserved during transformation requires paying careful attention to the flow of values through the program. This thesis presents conditions under which such transformations can be applied. This thesis then shows how to use a standard transformation-based optimizer to optimize these joins

Book excerpt: Abstract: "Database programming languages like O2, E, and O++ include the ability to iterate through a set. Nested iterators can be used to express joins. This paper describes compile-time optimizations similar to relational transformations like join reordering for such programming constructs. This paper also shows how to use a standard transformation- based optimizer to optimize these joins. An optimizer built using the EXODUS Optimizer Generator [GRAE87] was added to the Bell Labs O++ [AGRA89] compiler. We used the resulting optimizing compiler to experimentally validate the ideas in this paper. The experiments show that this technique can significantly improve the performance of database programming languages."

Book excerpt: The analysis shows that the transformations can significantly reduce the number of I/Os performed, even when both the initial and transformed programs use the same join method."

Download or read book Languages Compilers and Run Time Systems for Scalable Computers written by Boleslaw K. Szymanski and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Language, Compilers and Run-time Systems for Scalable Computers contains 20 articles based on presentations given at the third workshop of the same title, and 13 extended abstracts from the poster session. Starting with new developments in classical problems of parallel compiler design, such as dependence analysis and an exploration of loop parallelism, the book goes on to address the issues of compiler strategy for specific architectures and programming environments. Several chapters investigate support for multi-threading, object orientation, irregular computation, locality enhancement, and communication optimization. Issues of the interface between language and operating system support are also discussed. Finally, the load balance issues are discussed in different contexts, including sparse matrix computation and iteratively balanced adaptive solvers for partial differential equations. Some additional topics are also discussed in the extended abstracts. Each chapter provides a bibliography of relevant papers and the book can thus be used as a reference to the most up-to-date research in parallel software engineering.

This book was released on 1996-12-04 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This program is an electronic adaptation of work on the Comprehensive Classification of Pelvic Fractures by M. Tile, D. Helfet, J. Kellam, B. Isler, S. Nazarian, R.J. Judet, E. Letournel, and M.E. Müller. It includes sample X-rays, CT slices and 3D movies. In addition, a complete dictionary explains important terms and concepts, and a database is provided to record individual patient data such as fracture code, dates of treatment, and evaluation information. Multiple queries may be performed by fracture code or other criteria to retrieve an individual patient. With the use of this program careful classification and accurate documentation of treated fractures will facilitate research into the effectiveness of treatment.

This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the though 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 concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemi nation. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation 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 37 (thesis year 1992) a total of 12,549 thesis titles from 25 Canadian and 153 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 37 reports theses submitted in 1992, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "High level programming language features have long been seen as improving programmer efficiency at some cost in program efficiency. When features such as object-orientation and fine-grained concurrency, which greatly simplify expression of complex programs, are used parsimoniously, their effectiveness is mitigated. It is my thesis that these features can be implemented efficiently through interprocedural analysis and transformation. By specializing their implementation to the contexts in which they are used, the program's efficiency is not adversely affected by the flexibility of the language. The specific contributions herein are: 1) an adaptive flow analysis for pracical precise analysis of object-oriented programs, 2) a cloning algorithm for building specialized versions of general abstractions, 3) a set of optimizations for removing object-oriented and fine-grained concurrency overhead, and 4) a hybrid sequential-parallel execution model which adapts to the availability of data. The effectiveness of this framework has been empirically validated on standard benchmarks. It is publicly available as part of the Illinois Concert system (http://www-csag.cs.uiuc.edu)."

Download or read book Object oriented Concurrent Programming written by Akinori Yonezawa and published by . This book was released on 1987 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with a major theme of the Japanese Fifth Generation Project, which emphasizes logic programming, parallelism, and distributed systems. It presents a collection of tutorials and research papers on a new programming and design methodology in which the system to be constructed is modeled as a collection of abstract entities called "objects" and concurrent messages passing among objects. This methodology is particularly powerful in exploiting as well as harnessing the parallelism that is naturally found in problem domains. The book includes several proposals for programming languages that support this methodology, as well as the applications of object-oriented concurrent programming to such diverse areas as artificial intelligence, software engineering, music synthesis, office information systems, and system programming. It is the first compilation of research results in this rapidly emerging area. Contents:Concurrent Programming Using Actors. Concurrent Object-Oriented Programming in Act-1. Modelling and Programming in a Concurrent Object-Oriented Language, ABCL/1. Concurrent Programming in ConcurrentSmallTalk.
