This document describes a software package which implements a parallel hybrid (direct/iterative) linear solver based on the Schur complement method for solving a general sparse linear system of equations. The package is named parallel domain decomposition Schur complement based linear solver, or PDSLin in short. We give a brief description of the algorithm, installation, calling sequences, and data structures of PDSLin.
