SuperLU_MT

Abstract

SuperLU_MT contains a set of subroutines to solve a sparse linear system A*X=B. It uses Gaussian elimination with partial pivoting (GEPP). The columns of A may be preordered before factorization; the preordering for sparsity is completely separate from the factorization. SuperLU_MT is a parallel extension to the serial SuperLU library. SuperLU_MT is implemented in ANSI C, with multithreading extension, for example, using POSIX threads. Currently, only the LU factorization routine, which is the most time-consuming part of the solution process, is parallelized on machines with a shared address space. The other routines, such as column preordering and the forward and back substitutions are performed sequentially. This "alpha" release contains only double-precision real data type.
