PSPASES (Parallel Sparse Symmetric Direct Solver Library)
- Abstract
- PSPASES is a stand-alone MPI-based parallel library for solving linear systems of equations involving sparse symmetric positive definite matrices. The library efficiently implements the scalable parallel algorithms developed by authors, for each of the four phases of direct solution method; viz. ordering, symbolic factorization, numerical Cholesky factorization, and solution of triangular systems.
PSPASES uses ParMETIS and METIS as default libraries for computing fill- reducing ordering, but it also accepts user supplied ordering. Different functional interfaces are provided for each of the phases of the solver and a simple interface is also provided for easy use. The user can use these interfaces to solve multiple systems with same nonzero structures; to solve same system for multiple right hand sides; and to get different statistical information such as the memory requirements of the solver and the quality of the ordering.
