Function Documentation

reduce_over_local_particles()

template<typename ResultType >

ResultType reduce_over_local_particles	(	CellStructure const &	cs,
		std::invocable< ResultType &, Particle const & > auto	add_partial,
		std::invocable< ResultType &, ResultType const & > auto	reduce_op
	)

Run a reduction over all particles.

Parameters

cs	cell structure to iterate over
add_partial	function that accumulates a result from a single particle
reduce_op	function that joins two reduction results

both functions have to implement the same reduction.
