aim: simplified interface to PETSC solvers, Mat, Vec

• independent of Seq-MPI
• application to parallel PETSC mapping
• preallocation by abstract assembly

Todo:

• samostatny objekt LS
• samostatne objekty pro matici a vektor
• objekty pro mapovani indexu a jejich automaticke pouziti pri asemblaci
• podminene veci jako LS View a old_4_new
• funkcni stavy LS
• solve jako metoda
• nastaveni parametru na volajici strane (zavisle na problemu)

Function Documentation

void solve_system	(	struct Solver *	solver,
		struct LinSys *	system
	)

Solves a given linear system.

Call user selected internal or external solver.

Parameters

[in]	solver	solver structure to use
[in,out]	system	linear system to solve, conatains also result

Precondition

Initialized solver. Assembled system.

Postcondition

Valid solution.

set command line for external solvers

Definition at line 178 of file solve.cc.

void solver_init	(	Solver *	solver,
		Input::AbstractRecord	in_rec
	)

Initialize a solver structure.

Initialize all members form the users options. Possibly initialize specific solver parameters.

Parameters

[in]	solver	already allocated structure to be initialized
[in]	in_rec	input record
