Available in PDF, EPUB and Kindle. Book excerpt: Parallel algorithms are presented for updating a minimum spanning tree when the cost of an edge changes or when a new node is inserted in the underlying graph. The machine model used is a parallel random access machine which allows simultaneous reads but prohibits simultaneous writes into the same memory location. The algorithms described in this paper for updating a minimum spanning tree require O(log n) time and O(n square) processors. These algorithms are efficient when compared to previously known algorithms for initial construction of a minimum spanning tree that require O(log n to the base 2) time and use O(n square) processors.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together recent developments in Alzheimer's disease research with related discoveries in the field of cell biology. The book moves between basic cell biological concepts that form the underpinnings of modern Alzheimer's disease research, and current findings about proteins and cellular processes affected by the disease. Divided into three topics, the book addresses (1) protein trafficking, a problem that has become germane to the study of the amyloid precursor protein; (2) phosphorylation, a problem that underlies studies of the pathological transformation of tau to paired helical filaments; and (3) cell death, a pervasive problem in neurodegeneration.

This book was released on 1994-06-08 with total page 860 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the proceedings of the 5th International Conference Parallel Architectures and Languages Europe (PARLE '94), held in Athens, Greece in July 1994. PARLE is the main Europe-based event on parallel processing. Parallel processing is now well established within the high-performance computing technology and of stategic importance not only to the computer industry, but also for a wide range of applications affecting the whole economy. The 60 full papers and 24 poster presentations accepted for this proceedings were selected from some 200 submissions by the international program committee; they cover the whole field and give a timely state-of-the-art report on research and advanced applications in parallel computing.

This book was released on 2012-12-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: This IMA Volume in Mathematics and its Applications ALGORITHMS FOR PARALLEL PROCESSING is based on the proceedings of a workshop that was an integral part of the 1996-97 IMA program on "MATHEMATICS IN HIGH-PERFORMANCE COMPUTING. " The workshop brought together algorithm developers from theory, combinatorics, and scientific computing. The topics ranged over models, linear algebra, sorting, randomization, and graph algorithms and their analysis. We thank Michael T. Heath of University of lllinois at Urbana (Com puter Science), Abhiram Ranade of the Indian Institute of Technology (Computer Science and Engineering), and Robert S. Schreiber of Hewlett Packard Laboratories for their excellent work in organizing the workshop and editing the proceedings. We also take this opportunity to thank the National Science Founda tion (NSF) and the Army Research Office (ARO), whose financial support made the workshop possible. A vner Friedman Robert Gulliver v PREFACE The Workshop on Algorithms for Parallel Processing was held at the IMA September 16 - 20, 1996; it was the first workshop of the IMA year dedicated to the mathematics of high performance computing. The work shop organizers were Abhiram Ranade of The Indian Institute of Tech nology, Bombay, Michael Heath of the University of Illinois, and Robert Schreiber of Hewlett Packard Laboratories. Our idea was to bring together researchers who do innovative, exciting, parallel algorithms research on a wide range of topics, and by sharing insights, problems, tools, and methods to learn something of value from one another.

Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, a parallel Minimum Spanning Tree algorithm (MST) is implemented under a Bulk Synchronous Parallel (BSP) graph computation platform. Given a graph with positive weights, MST problem is to find a minimum weight set of edges that connects all of the vertices. MST has been an interesting topic of graph theory for a long time and it has many applications: network design, approximation algorithm of Steiner Tree, cluster analysis, etc. There are classic algorithms of finding the MST. When it comes to the big graph, however, these options do not work very well. In the last decade, many efficient frameworks of dealing big data have been proposed: MapReduce, Pregel, etc. Moreover, the BSP graph processing system makes it possible to run the parallel graph algorithms even in a single machine. In this study, a parallel MST algorithm is implemented based on a BSP-like graph processing platform. In the implementation, there are some classic parallel algorithm design issues: leader selection, information synchronization, etc. One concrete example is provided to go through all the algorithm details. A detailed experimental evaluation is also attached which shows the algorithm performance and possible direction for future improvement.

Download or read book Parallel Implementation of Bor vka s Minimum Spanning Tree Algorithm written by Sun Chung and published by . This book was released on 1996 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "We study parallel algorithms for the minimum spanning tree problem, based on the sequential algorithm of Borůvka. The target architectures for our algorithm are asynchronous, distributed-memory machines. Analysis of our parallel algorithm, on a simple model that is reminiscent of the LogP model, shows that in principle a speedup proportional to the number of processors can be achieved, but that communication costs can be significant. To reduce these costs, we develop a new randomized linear work pointer jumping scheme that performs better than previous linear work algorithms. We also consider empirically the effects of data imbalance on the running time. For the graphs used in our experiments, load balancing schemes result in little improvement in running times. Our implementations on sparse graphs with 64,000 vertices on Thinking Machine's CM-5 achieve a speedup factor of about 4 on 16 processors. On this environment, packaging of messages turns out to be the most effective way to reduce communication costs."
