stapl::skeletons::skeleton_manager Class Reference

skeleton_manager is the core entity of the skeleton framework. It uses an environment, a set of input views, and a skeleton to evaluate (spawn) a skeleton. An evaluated (spawned) skeleton can be represented differently in different environments. For example, a spawned skeleton in a taskgraph_env is a task graph. A spawned skeleton in a graphviz_env is a GraphViz representation of the dependence graph, etc. More...

Detailed Description

skeleton_manager is the core entity of the skeleton framework. It uses an environment, a set of input views, and a skeleton to evaluate (spawn) a skeleton. An evaluated (spawned) skeleton can be represented differently in different environments. For example, a spawned skeleton in a taskgraph_env is a task graph. A spawned skeleton in a graphviz_env is a GraphViz representation of the dependence graph, etc.

In addition, skeleton_manager has another important role in the skeleton framework. Imagine the case that you would like to pause the spawning process of a skeleton, possibly due to the limited memory that you have on your system. skeleton_manager can do that using the famous Memento design skeleton. A Memento design skeleton can save and restore the state of a process. You can use record_state and resume to perform such operations in skeleton_manager.

Member Function Documentation

resume()

void stapl::skeletons::skeleton_manager::resume

(

)

This method resumes the spawning process by spawning the element in the front of the memento deque if it is not a lazy element.

If all the elements of the memento double-ended queue are already resumed and there is nothing else left to spawn, the skeleton manager assumes it is done with the spawning process and will not be invoked anymore by the paragraph.

execute()

template<typename Skeleton , typename Env , typename ... V>

void stapl::skeletons::skeleton_manager::execute	(	Skeleton &&	skeleton,
		Env	env,
		V &...	view
	)

The execute method starts the spawning process of a skeleton, given a set of input, in a given environment. This method is called once per skeleton execution. It processes inputs and makes proper flows out of the inputs and sets the size of the skeletons in order to make them ready for the execution.

Parameters

skeleton	the skeleton to be spawned
env	the environment that this skeleton is going to be evaluated in
view	the set of input/output data passed to the skeleton
