PCFactorSetMatSolverType

sets the solver package that is used to perform the factorization

Synopsis

#include "petscpc.h" 
PetscErrorCode PCFactorSetMatSolverType(PC pc, MatSolverType stype)

Logically Collective

Input Parameters

• pc - the preconditioner context

• stype - for example, MATSOLVERSUPERLU, MATSOLVERSUPERLU_DIST, MATSOLVERMUMPS

Options Database Key

• -pc_factor_mat_solver_type - petsc, superlu, superlu_dist, mumps, cusparse

Note

By default this will use the PETSc factorization if it exists
