[petsc-dev] Elemental for sparse, distributed-memory, direct, quad-precision linear solves?

[Stefano Zampini]

Interface to the sparse elemental solver is almost done in https://bitbucket.org/petsc/petsc/branch/stefano_zampini/new-elemental-interface

I did not have time to finish it, and I’m not sure if Elemental now supports user-defined distributions for the vectors.
