MATSOLVERMUMPS

A matrix type providing direct solvers (LU and Cholesky) for distributed and sequential matrices via the external package MUMPS. Works with MATAIJ and MATSBAIJ matrices

Options Database Keys

-mat_mumps_icntl_4 <0,...,4> - print level
-mat_mumps_icntl_6 <0,...,7> - matrix prescaling options (see MUMPS User's Guide)
-mat_mumps_icntl_7 <0,...,7> - matrix orderings (see MUMPS User's Guidec)
-mat_mumps_icntl_9 <1,2> - A or A^T x=b to be solved: 1 denotes A, 2 denotes A^T
-mat_mumps_icntl_10 <n> - maximum number of iterative refinements
-mat_mumps_icntl_11 <n> - error analysis, a positive value returns statistics during -ksp_view
-mat_mumps_icntl_12 <n> - efficiency control (see MUMPS User's Guide)
-mat_mumps_icntl_13 <n> - efficiency control (see MUMPS User's Guide)
-mat_mumps_icntl_14 <n> - efficiency control (see MUMPS User's Guide)
-mat_mumps_icntl_15 <n> - efficiency control (see MUMPS User's Guide)
-mat_mumps_cntl_1 <delta> - relative pivoting threshold
-mat_mumps_cntl_2 <tol> - stopping criterion for refinement
-mat_mumps_cntl_3 <adelta> - absolute pivoting threshold
