template<typename T >

void cntr::herm_matrix< T >::Bcast_timestep	(	int	tstp,
		int	root
	)

Broadcasts the herm_matrix at a given time step to all tasks.

Purpose

Broadcasts the herm_matrix at a given time step tstp to all tasks.

Parameters

tstp	Time step which should be broadcasted.
root	The task rank from which the herm_matrix should be broadcasted.
