Amesos2: Linear system segfaults w/ SuperLU, SuperLU_DIST, & UMFPACK, but not with KLU2
Created by: mhoemmen

@vbrunini found a Tpetra linear system on a single MPI process, that makes Amesos2 segfault when using SuperLU
, SuperLU_DIST
, or UMFPACK
. However, KLU2
does not segfault.
I have put the linear system through R&A and will post it as a pull request. I just want to make this issue now so I can put the issue number in the PR.
@vbrunini 's guess is that Amesos2 does not like matrices that have "gaps" in their row Map. That is the case for the matrix in the test that I will post.
