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 or OpenMP. 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. +The library provides functionality for both real and complex +matrices, in both single and double precision. + +Xiaoye S.
