Detailed Description

general solve function to solve Ax = b in single/double precision

dispatcher solve function which calls the appropiate solver/preconditioner according to the config settings

Parameters

[in]	A	linear operator like matrix multiplication
[in]	b	right hand side
[in,out]	x	start vector, holds solution in the end
[in]	ext_x	extent of x
[in]	exchange	boundary exchange function
[in]	tol_opt	optional stopping tolerance for relative residual
[in]	maxiter_opt	optional maximum number of iterations

Returns

number of iterations
