Function Documentation

int exclusion_eval	(	struct exclusion *	b,
		int	N,
		struct engine *	e,
		double *	epot_out
	)

Evaluate a list of exclusioned interactoins.

Parameters:

b	Pointer to an array of exclusion.
N	Nr of exclusions in b.
e	Pointer to the engine in which these exclusions are evaluated.
epot_out	Pointer to a double in which to aggregate the potential energy.

Returns:

exclusion_err_ok or <0 on error (see exclusion_err)

int exclusion_eval_div	(	struct exclusion *	b,
		int	N,
		int	nr_threads,
		int	cid_div,
		struct engine *	e,
		double *	epot_out
	)

Evaluate a list of exclusioned interactoins.

Parameters:

b	Pointer to an array of exclusion.
N	Nr of exclusions in b.
nr_threads	Number of computational threads.
cid_div	cell id modulus.
e	Pointer to the engine in which these exclusions are evaluated.
epot_out	Pointer to a double in which to aggregate the potential energy.

Returns:

exclusion_err_ok or <0 on error (see exclusion_err)

Computes only the interactions on particles inside cells c where c->id % nr_threads == cid_div.

int exclusion_eval_mod	(	struct exclusion *	b,
		int	N,
		int	nr_threads,
		int	cid_mod,
		struct engine *	e,
		double *	epot_out
	)

Evaluate a list of exclusioned interactoins.

Parameters:

b	Pointer to an array of exclusion.
N	Nr of exclusions in b.
nr_threads	Number of computational threads.
cid_mod	cell id modulus.
e	Pointer to the engine in which these exclusions are evaluated.
epot_out	Pointer to a double in which to aggregate the potential energy.

Returns:

exclusion_err_ok or <0 on error (see exclusion_err)

Computes only the interactions on particles inside cells c where c->id % nr_threads == cid_mod.
