A Parallel Sparse Hybrid Solver And Its Relations To Graphs And Hypergraphs
2012
Zenodo
In this whitepaper, we review the state-of-the-art hybrid solver, which uses generalized form DS factorization, for solving system of equations of the form Ax = f, and this solver's relations to graphs and hypergraphs. We investigate two different reordering strategies for the DS factorization preconditioning scheme: reordering via graph partitioning (GP) and reordering via hypergraph partitioning (HP).In the GP scheme, the partitioning objective of minimizing the edge cutsize corresponds to
