and it doesn't seem to use a linear solver which is likely
why it showed better performance. Do you have any suggestions for
dealing with problems like this?

Hello All,
I'm trying to use the SLEPc Krylov-Schur implementation to solve a
general eigenvalue problem. I have a monitor on my solver and the
solutions appear to converge correctly when using the approximation for
the residual norm in the algorithm. However, when the solutions are
displayed

Hello All,
As there isn't a SLEPc specific list, it was recommended that I bring my
question here. I am using SLEPc to solve a generalized eigenvalue
problem generated as part of the Finite Element Method, but am having
difficulty getting the diagonalizer to converge. I am worried that the

problems with it.
