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

This book was released on 1991 with total page 29 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. 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."

This book was released on 1996 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Software development for parallel computers has been recognized as one of the bottlenecks preventing their widespread use. In this thesis we examine two complementary approaches for addressing the challenges of high performance and enhanced programmability in parallel programs: automated optimizations and object-orientation. We have developed the parallel object-oriented language Charm++ (an extension of C++), which enables the benefits of object-orientation to be applied to the problems of parallel programming. In order to improve parallel program performance without extra effort, we explore the use of automated optimizations. In particular, we have developed techniques for automating run-time optimizations for parallel object-oriented languages. These techniques have been embodied in the Paradise post-mortem analysis tool which automates several run-time optimizations without programmer intervention. Paradise builds a program representation from traces, analyzes characteristics, chooses and parameterizes optimizations, and generates hints to the Charm++ run-time libraries. The optimizations researched are for static and dynamic object placement, scheduling, granularity control and communication reduction. We also evaluate Charm++, Paradise and several run-time optimization techniques using real applications, including an N-body simulation program, a program from the NAS benchmark suite, and several other programs."

Book Synopsis Languages, Compilers and Run-Time Systems for Scalable Computers by : Boleslaw K. Szymanski
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.

Book Synopsis Optimization of Object-oriented and Concurrent Programs by : John Bradley Plevyak
Download or read book Optimization of Object-oriented and Concurrent Programs written by John Bradley Plevyak and published by . This book was released on 1996 with total page 520 pages. 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)."

Book Synopsis Object-oriented Concurrent Programming by : Akinori Yonezawa
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. Orient84K: An Object-Oriented Concurrent Programming Language for Knowledge Representation. POOL-T: A Parallel Object-Oriented Programming Language. Concurrent Strategy Execution in Omega.

Book Synopsis Applying Loop Optimizations to Object-oriented Abstractions Through General Classification of Array Semantics by : D. Quinlan
Download or read book Applying Loop Optimizations to Object-oriented Abstractions Through General Classification of Array Semantics written by D. Quinlan and published by . This book was released on 2004 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimizing compilers have a long history of applying loop transformations to C and Fortran scientific applications. However, such optimizations are rare in compilers for object-oriented languages such as C++ or Java, where loops operating on user-defined types are left unoptimized due to their unknown semantics. Our goal is to reduce the performance penalty of using high-level object-oriented abstractions. We propose an approach that allows the explicit communication between programmers and compilers. We have extended the traditional Fortran loop optimizations with an open interface. Through this interface, we have developed techniques to automatically recognize and optimize user-defined array abstractions. In addition, we have developed an adapted constant-propagation algorithm to automatically propagate properties of abstractions. We have implemented these techniques in a C++ source-to-source translator and have applied them to optimize several kernels written using an array-class library. Our experimental results show that using our approach, applications using high-level abstractions can achieve comparable, and in cases superior, performance to that achieved by efficient low-level hand-written codes.
