Sparse Solver Routines
Intel® oneAPI Math Kernel Library (oneMKL)
The terms and concepts required to understand the use of the sparse solver routines are discussed in the
Intel® oneAPI Math Kernel Library
Appendix "Linear Solvers Basics"
. If you are familiar with linear sparse solvers and sparse matrix storage schemes, you can skip these sections and go directly to the interface descriptions.
See the description of
- the direct sparse solver based on PARDISO* which is referred to here as Intel MKL PARDISO;
- the alternative interface for the direct sparse solver which is referred to here as the DSS interface;
- iterative sparse solvers (ISS) based on the reverse communication interface (RCI);
- and two preconditioners based on the incomplete LU factorization technique.
