I'm wondering if anyone is using Iterative Sparse Solver since I can't find any related messages on this forum.
My knowledge of the iterative solvers is very basic and therefore I'm just following the examples supplied with the MKL.
In the range of problems we are dealing with the zeros are located at diagonal and the solver just can't handle that.
I'm wondering if anyone else is using the iterative sparse solver and if anyone else is experiencing the same problem.
