It looks like Clique was merged into Elemental, so optimistically that wouldn't be an issue. On Tue, Aug 23, 2016 at 2:15 PM, Matthew Knepley wrote: > On Tue, Aug 23, 2016 at 3:01 AM, Patrick Sanan > wrote: >> >> Can I use elemental to directly solve

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. On Aug 23, 2016, at 3:15 PM,

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

2016-08-23 Thread Patrick Sanan
Can I use elemental to directly solve a sparse, distributed-memory (MPI), quad-precision linear system? If so, with the introduction of an interface, could this provide a way to support such a solve via an external package for PETSc?
