stapl::skeletons::local_env Class Reference

This environment tries to behave as a taskgraph_env on a single location. In other words, it runs the workfunctions instead of creating tasks, and stores the values produced by tasks and keeps them as long as they are needed (num_succs is not 0). You should consider this environment as the sequential version of the taskgraph_env. More...

This environment tries to behave as a taskgraph_env on a single location. In other words, it runs the workfunctions instead of creating tasks, and stores the values produced by tasks and keeps them as long as they are needed (num_succs is not 0).

Member Function Documentation

spawn_element() [1/2]

template<bool isResult, typename WF , typename ... In>

void stapl::skeletons::local_env::spawn_element	(	std::size_t	tid,
		int	result_id,
		WF const &	wf,
		std::size_t	num_succs,
		In &&...	in
	)

Runs the workfunction given on the given inputs and stores the value in the directory of the dependencies.

Parameters

tid	the unique id assigned for the result of the invocation of the workfunction
wf	the workfunction to be executed
result_id	result_id of this task if it has one
num_succs	the exact number of successors for this element. Remember that in some cases this value is set to stapl::defer_specs (when the spawner is in SET_HOLD mode)
in...	the producer information for the task's input arguments.

spawn_element() [2/2]

template<bool isResult, typename WF , typename... In>

void stapl::skeletons::local_env::spawn_element	(	std::false_type	,
		std::size_t	tid,
		std::size_t	result_id,
		std::vector< std::size_t > const &	notifications,
		WF const &	wf,
		std::size_t	num_succs,
		In &&...	in
	)

Runs the workfunction given on the given inputs and stores the value in the directory of the dependencies.

Parameters

tid	the unique id assigned for the result of the invocation of the workfunction
wf	the workfunction to be executed
notifications	list of the nodes which can proceed as soon as this node is done
num_succs	the exact number of successors for this element. Remember that in some cases this value is set to stapl::defer_specs (when the spawner is in SET_HOLD mode)
in...	the producer information for the task's input arguments.
