Detailed Description

Wrapper for the Euclid preconditioner in Hypre.

Euclid implements the Parallel Incomplete LU factorization technique. For more information see: "A Scalable Parallel Algorithm for Incomplete Factor Preconditioning" by David Hysom and Alex Pothen, https://doi.org/10.1137/S1064827500376193

Parameters can be set using native Hypre functions, e.g.

HYPRE_EuclidSetLevel(precond, 2);

See the Hypre Reference Manual for the available parameters.
