Makes the FGMRES iterations.
Retrieves the number of the current iteration and updates the solution.
Several aspects of the Intel MKL RCI ISS interface are platform-specific and language-specific. To promote portability across platforms and ease of use across different languages, include one of the Intel MKL RCI ISS language-specific header files.
Intel MKL does not support the RCI ISS interface unless you include the language-specific header file.
Preconditioners, or accelerators are used to accelerate an iterative solution process. In some cases, their use can reduce the number of iterations dramatically and thus lead to better solver performance. Although the terms preconditioner and accelerator are synonyms, hereafter only preconditioner is used.
ILU0 preconditioner based on incomplete LU factorization of a sparse matrix.
ILUT preconditioner based on the incomplete LU factorization with a threshold of a sparse matrix.
