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

Dear Sir. Ying,

Thank you very much for your sharing information. I will try to follow the guide to solve my problem. However, I think it is not easy for me to solve it without any mistake. 

I hope I will receive more your suggestions in the future.

Yours sincerely,
