Detailed Description

Distributes sets of shells either statically or dynamically.

Constructor & Destructor Documentation

DistShell()

sc::DistShell::DistShell	(	const Ref< MessageGrp > &	,
		int	nthread,
		int	mythread,
		const Ref< ThreadLock > &	lock,
		const Ref< GaussianBasisSet > &	bs,
		bool	dynamic,
		int	max_nfunctions = -1,
		int	max_nshell = 1,
		SharedData *	shared = 0
	)

The DistShell class is used to distribute sets of shells to compute tasks.

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

Member Function Documentation

get_task()

int sc::DistShell::get_task	(	int &	I,
		int &	N
	)

Copies "payload" (I is the first shell of the shell set, in the increasing-size order, and N is the number of shells) and returns 1.

When there are no more shells to be processed by this processor, 0 is returned.

set_print_percent()

void sc::DistShell::set_print_percent

(

double

p

)

How often to print status from node 0.

If p > 100.0, then no printing will be done.
