I have in mind to use slepc to to use to get the solution, since it has all the necessary algorithms, but I am trying to understand how to get my code to have that problem solved locally, serially, within the context of a larger parallel problem. Is it sufficient to just declare the matrix associated with the eigenvalue problem to be of sequential type?</blockquote>
