A Novel Partitioning Method for Accelerating the Block Cimmino Algorithm
F. Sukru Torun, Murat Manguoglu, Cevdet Aykanat
We propose a novel block-row partitioning method in order to improve the convergence rate of the block Cimmino algorithm for solving general sparse linear systems of equations. The…
1-D and 2-D Parallel Algorithms for All-Pairs Similarity Problem
Eray Özkural, Cevdet Aykanat
All-pairs similarity problem asks to find all vector pairs in a set of vectors the similarities of which surpass a given similarity threshold, and it is a computational kernel in d…
Analyzing and enhancing OSKI for sparse matrix-vector multiplication
Kadir Akbudak, Enver Kayaaslan, Cevdet Aykanat
Sparse matrix-vector multiplication (SpMxV) is a kernel operation widely used in iterative linear solvers. The same sparse matrix is multiplied by a dense vector repeatedly in thes…
Technical Report on Hypergraph-Partitioning-Based Models and Methods for Exploiting Cache Locality in Sparse-Matrix Vector Multiplication
Kadir Akbudak, Enver Kayaaslan, Cevdet Aykanat
The sparse matrix-vector multiplication (SpMxV) is a kernel operation widely used in iterative linear solvers. The same sparse matrix is multiplied by a dense vector repeatedly in…
Improving the Load Balancing Performance of Vlasiator
Ata Turk, Cevdet Aykanat, G. Vehbi Demirci +2
This whitepaper describes the load-balancing performance issues that are observed and tackled during the petascaling of the Vlasiator codes. Vlasiator is a Vlasov-hybrid simulation…
Hypergraph Partitioning through Vertex Separators on Graphs
Enver Kayaaslan, Ali Pinar, Umit V. Catalyurek +1
The modeling flexibility provided by hypergraphs has drawn a lot of interest from the combinatorial scientific community, leading to novel models and algorithms, their applications…
