Thanks Bruno and Daniel for pointing to the other options. I can report that superlu_dist does indeed work through trilinos for my problem. And you are absolutely correct that it is not the easiest to install. It took me a few hours to work out the details for installing on my mac based on t

Actually Mumps is included in the Amesos solver used by TrilinosWrappers::SolverDirect("Amesos_Mumps"). You may have to recompile Trilinos with the corresponding flags to enable it (and probably deal.II as well). Am Donnerstag, 9. Februar 2017 20:52:16 UTC+1 schrieb Bruno Turcksin: > > 2017-02-

Interesting, I wondered if SuperLU_dist might be parallel but I hadn't looked into it yet. If it does work, then that certainly makes things much simpler since I have trilinos integrated well. I will look into installing it and see if it will work. I see what you mean by it not being the easi

Hi, this is not the answer to your question but if I understand correctly, everything works fine with Trilinos and the only reason why you need PETSc is to use MUMPS. If that's the case, instead of using Amesos_KLU with Trilinos, you can use SuperLU_dist (http://crd-legacy.lbl.gov/~xiaoye/Supe
