John - since you have at least used SLEPc, would you please give this patch a look? I think it is great that they did this for us!!

As you may know, we have recently released SLEPc 3.0.0, which has some incompatibilities with previous versions. We have done some changes in order to enable libMesh to use SLEPc 3.0.0. You have done a good job integrating SLEPc in libMesh, so it was very easy. I am attaching the changes as diff's with respect to your current svn repository. Just a few comments: - We have set Krylov-Schur as the default eigensolver. This is far better than the older Arnoldi. - We have removed the code that set the orthogonalization to MGS, because the default (iterative CGS) is much better. - We have added a dummy function solve_adjoint() in order to be able to compile. Please forward this message to the rest of libMesh developers. Let us know if further interaction is required regarding this. Best regards, Jose E. Roman ------ End of Forwarded Message
