Classes
struct	peclet::core::solver::HostCsrOp
	A general assembled sparse operator in CSR form: the diagonal is stored separately and the CSR (start/nbr/coef) holds only the OFF-diagonal entries. More...
struct	peclet::core::solver::AmgParams
class	peclet::core::solver::GraphAMG
	Smoothed-aggregation AMG hierarchy usable as z = M⁻¹ r (one symmetric V-cycle from a zero initial guess) — the CG preconditioner that makes the iteration count mesh-independent. More...
struct	peclet::core::solver::CgResult
	PCG on A x = b preconditioned by an already-built GraphAMG (one V-cycle per iteration). More...
