Classes
class	mpqc::TA::IntegralEnginePool< RefEngType >
	IntegralEnginePool is a class that will take a Ref<Engine> as a prototype and then clone it multiple times such that each thread has its own integral engine. More...

Functions
	mpqc::TA::IntegralEnginePool< RefEngType >::IntegralEnginePool (const RefEngType engine)
	IntegralEnginePool constructor it takes a sc::Ref<sc::IntegralEngine> and sets that as the prototype for all the thread local engines.

	mpqc::TA::IntegralEnginePool< RefEngType >::~IntegralEnginePool ()
	Delete the Engines that we allocated for TLS.

RefEngType	mpqc::TA::IntegralEnginePool< RefEngType >::instance ()
	Function that returns a clone of the prototype engine.

template<typename ShrPtrPool , class A >
void	mpqc::TA::fill_tiles (A &array, const ShrPtrPool &pool)

Detailed Description

Provides interface to get atomic basis integrals into TiledArray tensors.

Shell = a range of basis functions

IntegralEnginePool<Engine_type> engine_pool(seed_engine);

TiledArray::Array<double, 2> array = Integrals(world, engine_pool);

Function Documentation

template<typename ShrPtrPool , class A >

void mpqc::TA::fill_tiles	(	A &	array,
		const ShrPtrPool &	pool )

Initial function called to fill a TiledArray with integrals.

Parameters

[in,out]	array	is a TiledArray::Array that will be filled with data
[in]	pool	is an IntegralEnginePool object to provide integrals.

template<typename RefEngType >

RefEngType mpqc::TA::IntegralEnginePool< RefEngType >::instance ( )

inline

Function that returns a clone of the prototype engine.

The clone exist for only one thread to use and so should not be written to or used by any other thread.
