An exact algorithm for sparse matrix bipartitioning
The sparse matrix partitioning problem arises when minimizing communication in parallel sparse matrix-vector multiplications. Since the problem is NP-hard, heuristics are usually employed to find solutions. Here, we present a purely combinatorial branch-and-bound method for computing optimal bipartitionings of sparse matrices, in the sense that they have the lowest communication volume out of a...
متن کاملAn exact algorithm for MAX-CUT in sparse graphs
We study exact algorithms for the max-cut problem. Introducing a new technique, we present an algorithmic scheme that computes a maximum cut in graphs with bounded maximum degree. Our algorithm runs in time O∗(2(1−(2/∆))n). We also describe a max-cut algorithm for general graphs. Its time complexity is O∗(2mn/(m+n)). Both algorithms use polynomial space. Acknowledgements: The work was done whil...
متن کاملAn Exact Algorithm for the Mode Identity Project Scheduling Problem
In this paper we consider the non-preemptive variant of a multi-mode resource constrained project scheduling problem (MRCPSP) with mode identity, in which a set of project activities is partitioned into disjoint subsets while all activities forming one subset have to be processed in the same mode. We present a depth-first branch and bound algorithm for the resource constrained project schedulin...
متن کاملAn Approach for Parallelizing any General Unsymmetric Sparse Matrix Algorithm
In many large scale scientiic and engineering computations, the solution to a sparse linear system is required. We present a partial unsymmetric nested dissection method that can be used to parallelize any general unsymmetric sparse matrix algorithm whose pivot search can be restricted to a subset of rows and columns in the active submatrix. The submatrix is determined by the partial unsymmetri...
متن کاملAN ALGORITHM FOR FINDING THE EIGENPAIRS OF A SYMMETRIC MATRIX
The purpose of this paper is to show that ideas and techniques of the homotopy continuation method can be used to find the complete set of eigenpairs of a symmetric matrix. The homotopy defined by Chow, Mallet- Paret and York [I] may be used to solve this problem with 2""-n curves diverging to infinity which for large n causes a great inefficiency. M. Chu 121 introduced a homotopy equation...
