Full description
PaStiX (Parallel Sparse matriX package) is a scientific library that
provides a high performance parallel solver for very large sparse
linear systems based on direct methods. Numerical algorithms are
implemented in single or double precision (real or complex) using
LLt, LDLt and LU with static pivoting (for non symmetric matrices
having a symmetric pattern). This solver provides also an adaptive
blockwise iLU(k) factorization that can be used as a parallel
preconditioner using approximated supernodes to build a coarser
block structure of the incomplete factors.
