Struct ParallelGmresSolver 

pub struct ParallelGmresSolver {
    pub krylov_dim: usize,
    pub max_restarts: usize,
    pub tolerance: f64,
}

Parallel sparse direct solver using ILU(0) preconditioning.

For symmetric positive definite systems, prefer ParallelPcgSolver. This solver handles non-symmetric systems (e.g. convection-dominated problems).

Fields

krylov_dim: usize

Krylov subspace dimension (restart).

max_restarts: usize

Maximum number of outer restarts.

tolerance: f64

Convergence tolerance.

Implementations

impl ParallelGmresSolver

pub fn solve(&self, a: &CsrMatrix, b: &[f64], x: &mut [f64]) -> PcgStats

Solve A * x = b using restarted GMRES with diagonal preconditioning.

For symmetric positive definite systems prefer ParallelPcgSolver which is more efficient.
