Merge branch 'master' into barry/fix-successful-numerical-factorization-after-failure/master
The maint patch for the given problem cannot merge cleanly into next due to changes
in the same code in master (the introduction of MatFactorGetError()) therefor need
to merge in master and use the new construct before merging to next

Add interface to STRUMPACK-sparse.
STRUMPACK-sparse is a sparse direct solver and
preconditioner (using Hierarchically Semi-Separable matrices),
developed at LBNL, released under a BSD license:
http://portal.nersc.gov/project/sparse/strumpack/
This commit adds 2 interfaces to STRUMPACK-sparse: one for
aij/seq and one for aij/mpi matrices. It also adds a script to
the buildsystem to download/compile/install STRUMPACK-sparse.
I can get everything compiled with
./configure --download-strumpack --with-cxx-dialect=C++11 \
--with-openmp --download-scalapack --download-parmetis
--download-metis --download-ptscotch
(There was an issue compiling STRUMPACK-sparse as a shared
library, so it is now always static)
I tested the new code with the src/snes/examples/tutorials/ex5.c
example:
OMP_NUM_THREADS=2 mpirun -n 2 ./ex5 -da_grid_x 100 \
-da_grid_y 100 \
-pc_type lu -pc_factor_mat_solver_package strumpack_mpi \
-ksp_monitor -mat_strumpack_mpi_matinput DISTRIBUTED \
--sp_mc64job 0 --sp_reordering_method scotch --sp_verbose
The aij/mpi solver is called 'strumpack_mpi', the aij/seq solver
is 'strumpack'. All command line options are passed to the
STRUMPACK solver, including -h, which prints out the STRUMPACK
options.
STRUMPACK-sparse has 3 interfaces:
* A sequential/nulti-threaded interface. This one is used with
aij/seq matrices by selecting the 'strumpack' solver.
* A distributed memory solver with replicated interface. This
interface has the same input on every MPI proc (entire matrix
and rhs and solution vectors). Select this for aij/mpi, with
"-pc_type lu -pc_factor_mat_solver_package strumpack_mpi -mat_strumpack_mpi_matinput GLOBAL"
* A fully distributed solver, works with the aij/mpi block-row
distributed input matrix directly. Use with:
"-pc_type lu -pc_factor_mat_solver_package strumpack_mpi -mat_strumpack_mpi_matinput DISTRIBUTED"
