Detailed Description

Distributes shell pairs either statically or dynamically.

Constructor & Destructor Documentation

DistShellPair()

sc::DistShellPair::DistShellPair	(	const Ref< MessageGrp > &	,
		int	nthread,
		int	mythread,
		const Ref< ThreadLock > &	lock,
		const Ref< GaussianBasisSet > &	bs1,
		const Ref< GaussianBasisSet > &	bs2,
		bool	dynamic,
		SharedData *	shared = 0
	)

The DistShellPair class is used to distribute shell pair indices among tasks.

Both static (round-robin) and dynamic methods are supported.

Member Function Documentation

get_task()

int sc::DistShellPair::get_task	(	int &	P,
		int &	Q
	)

Puts the current PQ shell pair into P and Q and returns 1.

When there are no more shell pairs to be processed by this processor, 0 is returned. Once we start doing get_tasks, we have to go to the end if dynamic load balancing is used.

P belongs to bs1, and Q belongs to bs2. If (bs1 == bs2) then P is greater or equal to Q.
