Detailed Description

Base class for stealing policies.

Constructor & Destructor Documentation

steal_policy_base()

stapl::steal_policy_base::steal_policy_base ( size_type  chunk_size, size_type  fraction  )

noexcept

Constructs a new steal_policy_base.

Parameters

chunk_size	Number of entries to steal.
fraction	Fraction of the total entries to steal.

Member Function Documentation

process_steal_requests()

template<typename Scheduler >

void stapl::steal_policy_base::process_steal_requests	(	Scheduler &	scheduler,
		task_graph *	tg_ptr
	)

Processes steal requests that it got from thieves.

This function migrates work to the thieves. It will distribute work according to the steal requests that were received.

migrate_work()

template<typename Scheduler >

void stapl::steal_policy_base::migrate_work	(	Scheduler &	scheduler,
		location_type	loc,
		size_type	num_to_migrate,
		task_graph *	tg_ptr
	)

Migrate some work to a thief.

Parameters

scheduler	Scheduler to migrate work from.
loc	Thief to migrate work to.
num_to_migrate	How much work to migrate.
