EFFICIENT PARALLEL ALGORITHMS FOR SHORTEST PATH the cost of the link u ~ v (where u is the predecessor ofv in the list) equal to zero. Run again the parallel list ranking algorithm to this list resulting in the correct clockwise naming of the vertices of . It is possible to parallelize the sequential algorithm using a parallel DFS, however, the fastest parallel DFS algorithm is not work-efficient. Tarjan and Vishkin present the first work-efficient algorithm for biconnectivity [ ] (as stated in the paper the algorithm is not work-efficient, but it can be made so by using a work-efficient.
The goal of this paper is to point out that analyses of parallelism in computational problems have practical implications even when multiprocessor machines are not available. This is true because, in many cases, a good parallel algorithm for one problem may turn out to be useful for designing an efficient serial algorithm for another problem. ABSTRACT - This paper describes an efficient analogue binary image thinning algorithm for binary images. This algorithm improves the cardinal belongingss of thinning such as pixel connectivity, inordinate eroding, thinning,8-connectedness. The algorithm preserves the connectivity of an input image.
Efficient Parallel Algorithms book. Read reviews from world’s largest community for readers. This largely self-contained text is an introduction to the f 4/5. In this paper, we face the issue of concurrent versus exclusive reading in the design of a parallel algorithm for message passing-based distributed computing with an application to Lempel–Ziv data compression [1,2,3].Broadcasting a message from one to many processors in a network corresponds to concurrent reading on a random access shared memory parallel machine, while exclusive reading Author: Sergio De Agostino, Bruno Carpentieri, Raffaele Pizzolante.

Parallel graph algorithms have re-ceived significant attention since the start of parallel computing, and many elegant algorithms with good theoretical bounds have been developed over the decades (e.g., [3, 8, 21, 32, 44, 49, 53, 62– 64, 68, 69, 75, 87]).File Size: KB.
We present efficient parallel algorithms for solving three problems for series parallel graphs: 3-coloring, depth-first spanning tree, and breadth-first spanning tree. If the input is given by the decomposition tree, the first two problems can be solved in O (log n) time with O(n log n) processors, the last problem can be solved in O (log n log log n) time with O (n) by: CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract.
