Fredrik Ekre	fc53daa829	Update option generator ... Some solvers have option from the specific ParCSR solver + options for the general solver. This updates the option generator to handle this such that the specific method is preferred over the generic one. This patch also include the result of the generator applied to PCG, which has some specific options for ParCSRPCG.	3 years ago
Fredrik Ekre	635159e922	Wrap (ParCSR)PCG solver. ... Settings are passed as keyword arguments, just like BoomerAMG. The Precond argument (corresponding to PCGSetPrecond) is handled separately, and lets you pass another solver directly, instead of the solver pointer, the setup and solve functions, as in the SetPrecond C function. Example: precond = BoomerAMG(; options...) solver = PCG(; Precond = precond, options...)	3 years ago
Fredrik Ekre	5370aa77c7	Julia interface to HYPRE solvers ... This commits contains the solver interface: A = HYPREMatrix(...) b = HYPREVector(...) x = HYPREVector(...) solver = HYPRESolver(; options...) solve!(solver, x, A, b) where the abstract type HYPRESolver is replaced by a concrete solver implementation (this commit includes the concrete implementation/wrapping of BoomerAMG <: HYPRESolver). Solver settings are passed as keyword arguments to the solver constructor, cf. SetXXX functions in HYPRE. For example, to create a BoomerAMG solver, and setting the tolerance: solver = BoomerAMG(Tol = 1e-7) Keyword argument names correspond directly to the solvers SetXXX function in HYPRE; passing Tol corresponds to HYPRE_BoomerAMGSetTol(solver, 1e-7).	3 years ago
