MATSOLVERMKL_PARDISO#
A matrix type providing direct solvers, LU, for MATSEQAIJ matrices via the external package MKL PARDISO https://www.intel.com/content/www/us/en/docs/onemkl/developer-reference-c/2024-0/onemkl-pardiso-parallel-direct-sparse-solver-iface.html. Use -pc_type lu -pc_factor_mat_solver_type mkl_pardiso to use this direct solver
Options Database Keys#
- -mat_mkl_pardiso_65 - Suggested number of threads to use within MKL PARDISO 
- -mat_mkl_pardiso_66 - Maximum number of factors with identical sparsity structure that must be kept in memory at the same time

Notes#
Use -mat_mkl_pardiso_68 1 to display the number of threads the solver is using. MKL does not provide a way to directly access this
information.
