Limits of Parallelism Using Dynamic Dependency Graphs

by Jonathan Mak, Alan Mycroft
"... The advance of multi-core processors has led to renewed interest in extracting parallelism from programs. It is sometimes useful to know how much parallelism is exploitable in the limit for general programs, to put into perspective the speedups of various parallelisation techniques. Wall’s study [19 ..."
Abstract - Cited by 9 (0 self) - Add to MetaCart
[19] was one of the first to examine limits of parallelism in detail. We present an extension of Wall’s analysis of limits of parallelism, by constructing Dynamic Dependency Graphs from execution traces of a number of benchmark programs, allowing us better visualisation of the types of dependencies

Dynamic Program Slicing

by Hiralal Agrawal, Joseph R. Horgan , 1990
"... The conventional notion of a program slice---the set of all statements that might affect the value of a variable occurrence---is totally independent of the program input values. Program debugging, however, involves analyzing the program behavior under the specific inputs that revealed the bug. In th ..."
Abstract - Cited by 415 (7 self) - Add to MetaCart
. In this paper we address the dynamic counterpart of the static slicing problem---finding all statements that really affected the value of a variable occurrence for the given program inputs. Several approaches for computing dynamic slices are examined. The notion of a Dynamic Dependence Graph and its use

Interprocedural Slicing Using Dependence Graphs

by Susan Horwitz, Thomas Reps, David Binkley - ACM TRANSACTIONS ON PROGRAMMING LANGUAGES AND SYSTEMS , 1990
"... ... This paper concerns the problem of interprocedural slicing---generating a slice of an entire program, where the slice crosses the boundaries of procedure calls. To solve this problem, we introduce a new kind of graph to represent programs, called a system dependence graph, which extends previou ..."

A Framework for Dynamic Graph Drawing

by Robert F. Cohen, G. Di Battista, R. Tamassia, Ioannis G. Tollis - CONGRESSUS NUMERANTIUM , 1992
"... Drawing graphs is an important problem that combines flavors of computational geometry and graph theory. Applications can be found in a variety of areas including circuit layout, network management, software engineering, and graphics. The main contributions of this paper can be summarized as follows ..."
Abstract - Cited by 628 (44 self) - Add to MetaCart
as follows: ffl We devise a model for dynamic graph algorithms, based on performing queries and updates on an implicit representation of the drawing, and we show its applications. ffl We present several efficient dynamic drawing algorithms for trees, series-parallel digraphs, planar st-digraphs, and planar

The program dependence graph and its use in optimization

by Jeanne Ferrante, Karl J. Ottenstein, Joe D. Warren - ACM Transactions on Programming Languages and Systems , 1987
"... In this paper we present an intermediate program representation, called the program dependence graph (PDG), that makes explicit both the data and control dependence5 for each operation in a program. Data dependences have been used to represent only the relevant data flow relationships of a program. ..."

Efficiently computing static single assignment form and the control dependence graph

by Ron Cytron, Jeanne Ferrante, Barry K. Rosen, Mark N. Wegman, F. Kenneth Zadeck - ACM TRANSACTIONS ON PROGRAMMING LANGUAGES AND SYSTEMS , 1991
"... In optimizing compilers, data structure choices directly influence the power and efficiency of practical program optimization. A poor choice of data structure can inhibit optimization or slow compilation to the point that advanced optimization features become undesirable. Recently, static single ass ..."
Abstract - Cited by 1003 (8 self) - Add to MetaCart
assignment form and the control dependence graph have been proposed to represent data flow and control flow propertiee of programs. Each of these previously unrelated techniques lends efficiency and power to a useful class of program optimization. Although both of these structures are attractive

The geometry of graphs and some of its algorithmic applications

by Nathan Linial, Eran London, Yuri Rabinovich - COMBINATORICA , 1995
"... In this paper we explore some implications of viewing graphs as geometric objects. This approach offers a new perspective on a number of graph-theoretic and algorithmic problems. There are several ways to model graphs geometrically and our main concern here is with geometric representations that res ..."

-tensions. 0 For graphs embeddable in low-dimensional spaces with a small distortion, we can find low-diameter decompositions (in the sense of [4] and [34]). The parameters of the decomposition depend only on the dimension and the distortion and not on the size of the graph. 0 In graphs embedded this way

Dynamic capabilities and strategic management

"... The dynamic capabilities framework analyzes the sources and methods of wealth creation and capture by private enterprise firms operating in environments of rapid technological change. The competitive advantage of firms is seen as resting on distinctive processes (ways of coordinating and combining), ..."

Distortion invariant object recognition in the dynamic link architecture

Similarity Flooding: A Versatile Graph Matching Algorithm and Its Application to Schema Matching

by Sergey Melnik, Hector Garcia-molina, Erhard Rahm , 2002
"... Matching elements of two data schemas or two data instances plays a key role in data warehousing, e-business, or even biochemical applications. In this paper we present a matching algorithm based on a fixpoint computation that is usable across different scenarios. The algorithm takes two graphs (sch ..."

(schemas, catalogs, or other data structures) as input, and produces as output a mapping between corresponding nodes of the graphs. Depending on the matching goal, a subset of the mapping is chosen using filters. After our algorithm runs, we expect a human to check and if necessary adjust the results. As a
