Thanks, @brian-kelley ! I had assumed we could merge now but I see the WIP in the title was confusing. @euphoricpoptarts , let us know if you plan to add...

Segfault in dnrformat_loc3d.c

Tpetra::MultiVector contains a 2D Kokkos::View with the actual data. I suggest you can get the Kokkos::View and pass that to SuperLU. See https://docs.trilinos.org/dev/packages/tpetra/doc/html/classTpetra_1_1MultiVector.html

@jeanlucf22 Looks like you are doing things right on the Trilinos/Tpetra side. Sorry, not sure what the problem is here. I'm curious: The Amesos2 package already supports SuperLU-dist as a...

Zoltan2/Sphynx: Matrix-free version

@GrahamBenHarper Thanks, good to know. I agree that if the solver is matrix-free, then the partitioner needs to be matrix-free as well. You may have noticed I immediately put this...

Zoltan2/Sphynx: Matrix-free version

Note the geometric partitioners (RCB, MJ) in Zoltan2 are already "matrix-free" as they only require coordinates for the items (nodes, edges, cells) you want to partition. Sphynx is a graph...
