Detailed Description

template<typename Matrix_, typename Filter_, typename SolverBase_ = Solver::SolverBase<typename Matrix_::VectorTypeL>>
class FEAT::Solver::HypreSolverBase< Matrix_, Filter_, SolverBase_ >

Base-Class for solvers/preconditioners borrowed from HYPRE library.

This class acts as a base-class for all solvers that we borrow from the HYPRE library. As all our HYPRE solvers use the "IJ"-based ParCSR format, which corresponds to our "algebraic DOF partitioning", this class derives from the ADPSolverBase class, which takes care of the translation between the system matrix and the ADP data structures.

This base-class takes care of allocating, initializing and updating the required HYPRE matrix and vector objects, which are outsourced into an opaque core wrapper object.

void FEAT::Solver::HypreSolverBase< Matrix_, Filter_, SolverBase_ >::_download_cor ( VectorType &  vec_cor )

inlineprotected

Downloads the HYPRE correction vector.

This function first queries the vector values from HYPRE into the internal buffer and then downloads the contents to the given correction vector.

Parameters

[out]

vec_cor

The correction vector to download to.

Downloads the ADP vector values from the given array.

Parameters

[in,out]	vector	A transient reference to the local vector that receives the downloaded ADP value array. It is assumed to be allocated to the correct size, but its contents on entry are ignored.
[in]	val	A transient pointer to an array of length _get_adp_vector_size() that contains the ADP values that are to be downloaded to the output vector given by vector.

apply()

pure virtualinherited

Solver application method.

This method applies the solver represented by this object onto a given defect vector and returns the corresponding correction vector.

Note

Solvers which derive from the IterativeSolver base class also provide a correct() method which corrects an initial solution instead of starting with the null vector.

Parameters

[out]	vec_cor	The vector that shall receive the solution of the linear system. It is assumed to be allocated, but its numerical contents may be undefined upon calling this method.
[in]	vec_def	The vector that represents the right-hand-side of the linear system to be solved.

Attention

vec_cor and vec_def must not refer to the same vector object!

Returns

A Status code that represents the status of the solution step.

This function creates the HYPRE matrix and vector objects and initializes their structure/layout by using the algebraic DOF partitioning (ADP) that is managed by the base-class. This function also performs an initial upload of the matrix and vector values from the ADP structures (because HYPRE requires this), although these values may be undefined (but existent) at this point.
