Function Documentation

Solution_calculate_fitness_slave()

SOLUTION_PARALLEL_INLINE void Solution_calculate_fitness_slave	(	const HPElem *	hpChain,
		int	hpSize,
		MPI_Comm	comm
	)

Procedure that the slave nodes should execute.

Consists of waiting for MovChains, calculating its fitness, and sending the fitness back to node 0. The fitness is sent back with the same MPI_TAG that was received with the MovChain. The slave will return once the first element of the MovChain received is equal 0xFF.

Solution_pack()

SOLUTION_PARALLEL_INLINE void Solution_pack	(	Solution	sol,
		int	hpSize,
		void *	buf,
		int	maxSize,
		int *	position,
		MPI_Comm	comm
	)

Packs a Solution in the given buffer.

Solution_unpack()

SOLUTION_PARALLEL_INLINE Solution Solution_unpack	(	int	hpSize,
		void *	buf,
		int	maxSize,
		int *	position,
		MPI_Comm	comm
	)

Unpacks a Solution and returns it.
