915acf6b26 added relax_type 8, which uses ParCSRRelax, block Gauss-Seidel smoothed 
with L1-norms on off diagonal part of matrix (no CF-relaxation possible)

131fe342ff Redesigned routines that set smoother parameters (such as relax-types, 
number of sweeps, relaxation parameters, etc.) for BoomerAMG and
unstructured hybrid solver

96cb9359da removed the function and parameter int *smooth_option and replaced 
it by int smooth_type and int smooth_num_levels,
where smooth_type defines the type of complicated smoother (i.e. no
point smoother, e.g. Schwarz, Euclid, etc.) and smooth_num_levels the
number of levels for which the smoother is used starting with the finest level.

7aa95e4b53 added (inner and outer) relaxation parameters to Gauss-Seidel routines, 
also added a backward solve procedure.
This required an additional parameter for hypre_BoomerAMGRelax.
Complete list of  choices for smoothers are now:
relax_type = 0 -> Jacobi or CF-Jacobi
relax_type = 1 -> Gauss-Seidel <--- very slow, sequential
relax_type = 2 -> Gauss_Seidel: interior points in parallel, boundary sequential
relax_type = 3 -> hybrid: SOR-J mix off-processor, SOR on-processor with outer relaxation parameters (forward solve)
relax_type = 4 -> hybrid: SOR-J mix off-processor, SOR on-processor  with outer relaxation parameters (backward solve)
relax_type = 5 -> hybrid: GS-J mix off-processor, chaotic GS on-node
relax_type = 6 -> hybrid: SSOR-J mix off-processor, SSOR on-processor  with outer relaxation parameters
relax_type = 9 -> Direct Solve

252989f45a added various parameters for the more complex smoothers such 
as ParaSails, PILUT and Euclid (also added Euclid as a smoother)

3f5d30a2f4 added relaxation-weight for additive Schwarz-smoother and the 
possibility to change the number of sweeps for special smoothers
independently from the conventional smoothers

51b3675264 changed the Schwarz smoother so it can be also used as a preconditioner 
for CG , created the hypre_SchwarzData data structure , added some
parameters to the hypre_ParAMGData structure and deleted some that
were not needed anymore due to the new data structure

cd87ebc898 change of structure for the Schwarz smoother, which also effects the 
calling sequences of several of the Schwarz routines.

943519771f added a function that updates the residual for the Schwarz smoother 
if one uses more than one processor

cae021f54b added the possibility of using additional smoothers: 
ParaSails
Pilut

6e668ec001 When num_levels == 1 and max_levels > 1, relax_points now set to 0 2000-11-02 23:34:39 +00:00
lambda
a9e85e3983 When num_levels = 1, but max_levels > 1, switching to SIMPLEST smoother ONCE, 
hopefully to reduce execution time on diagonally dominant systems arising
from small-dt time stepping.

9681af56d2 Added command-line arguments: 
-w X.XX   sets relaxation weight to X.XX for weighted Jacobi
      -th X.XX  sets strong_threshold to X.XX

Changed from straight Jacobi to weighted Jacobi, but set the default
     weight to 1.0.

Eliminated the MatVec based Jacobi relaxation scheme (formerly relaxation
    type 2.  The type 0 version is more efficient.
