In Xolotl's "feature-petsc-kokkos" branch, I have moved our code to use the COO interface for preallocating and setting values in the Jacobian matrix. I have found that with some of our test cases, using more than one MPI rank results in a crash. Way down in
the preconditioner code in petsc a Mat gets computed that has "null" for the "productsymbolic" member of its "ops". It's pretty far removed from where we compute the Jacobian entries, so I haven't been able (so far) to track it back to an error in my code.
I'd appreciate some help with this from someone who is more familiar with the petsc guts so we can figure out what I'm doing wrong. (I'm assuming it's a bug in Xolotl.)</div>

Note that this is using the kokkos backend for Mat and Vec in petsc, but with a serial-only build of kokkos and kokkos-kernels. So, it's a CPU-only multiple MPI rank run.</div>
