Factorization-Based Graph Repartitionings [chapter]

Kateřina Jurková, Miroslav Tůma
2010 Lecture Notes in Computer Science  
The paper deals with the parallel computation of matrix factorization using graph partitioning-based domain decomposition.  ...  In this paper we propose to enhance the iterative strategy for balancing the decompositions from [13] by graph-theoretical tools. We propose the whole framework for the graph repartitioning.  ...  Framework for the graph-based repartitioning In this section we will split the problem of repartitioning into several simpler tasks.  ...

Clement Vuchener, Aurelien Esnard

In this paper, we present a new graph repartitioning algorithm which accepts to dynamically change the number of processors, assuming the load is already balanced.  ...  This algorithm is based on a theoretical result, that constructs optimal communication patterns with both a minimum migration volume and a minimum number of communications.  ...  We briefly review the most popular methods based on graph (or hypergraph) repartitioning techniques.  ...

Optimizing equijoin queries in distributed databases where relations are hash partitioned

Dennis Shasha, Tsong-Li Wang
1991 ACM Transactions on Database Systems  
We study the optimization problem that arises when the query processor must repartition the relations and intermediate results participating in a multijoin query.  ...  Using estimates of the sizes of intermediate relations, we show (1) optimum solutions for closed chain queries; (2) the NP-completeness of the optimization problem for star, tree, and general graph queries  ...  Figure 12 shows the application of algorithm HKH to the query graph in Figure 9 . Notice also that algorithm PH deteriorates significantly as the selectivity factors increase.  ...

Dynamic Repartitioning of Adaptively Refined Meshes

K. Schloegel, G. Karypis, V. Kumar
1998 Proceedings of the IEEE/ACM SC98 Conference  
On the other hand, diffusion-based schemes work well for slightly imbalanced graphs and for those in which imbalance occurs globally throughout the graph.  ...  Recently, parallel multilevel graph repartitioning techniques have been developed that can quickly compute high-quality repartitions for adaptive and dynamic meshes while minimizing the amount of data  ...  Recently, repartitioning schemes were presented based on both of these strategies [1, 9, 11, 10, 12, 13, 14] .  ...

Multilevel Diffusion Schemes for Repartitioning of Adaptive Meshes

Kirk Schloegel, George Karypis, Vipin Kumar
1997 Journal of Parallel and Distributed Computing  
If this new graph is partitioned from scratch, it may lead to an excessive migration of data among processors.  ...  Eventually, as the mesh evolves, the adapted mesh has to be repartitioned to ensure good load balance.  ...  In this paper, we present repartitioning algorithms based upon multilevel diffusion.  ...
