Iterative Sparse Solvers based on Reverse Communication Interface

Dear Sir/Madam,

I am grateful for the development of Intel Visual Fortran Compiler for Windows. It helps my work a lot.

I would like to ask about RCI ISS in the newest Intel MKL solver. I know that in Intel MKL, there is an RCI conjugate gradient solver.

Hence, does it work well with EBE-PCG (element by element preconditioner conjugate gradient) method or can I build my code for EBE-PCG method using Intel MKL solver?

Thank you very much!

Hi Tien-Dat,

Thank you for raising the question. As i understand, you may use some of MKL functions for example, sparse solver, sparse matrix * vector for your method.

Here is the functionality and example code for the RCI ISS in MKL developer guide for your reference
