Function Documentation

solver_copy()

static void solver_copy ( const SolverMatrix *  solvin, SolverMatrix *  solvout, pastix_coeftype_t  flttype  )

inlinestatic

Copy the solver matrix data structure from solvin to solvout.

Every data is copied, event the coefficient if they are allocated and initialized. It is also used to reallocate the data in a contiguous way after the initialization that allocates all internal arrays in multiple step which might results in fragmentation.

Warning

This function is not able to copy a solver matrix with low rank blocks yet.

Parameters

[in]	solvin	The solver matrix structure to duplicate.
[out]	solvout	The allocated pointer to the solver matrix structure that will contain the copy.
[in]	flttype	The floating point arithmetic used in the input solver matrix to know the size of the memory space to duplicate for the coefficients.
