Fredrik Ekre	11ddf91fd2	Add solve function that allocates the initial guess/output vector. This patch adds a function solve(::HYPRESolver, ::HYPREMatrix, ::HYPREVector) which initializes an output vector initialized to 0 and pass it to solve!.	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
