Detailed Description

Task plugging into state transition once task becomes ready.

This task is always paired up with an instance of ProcessReadyTask. This task takes the task _task and puts it into the _taskQueue. After that, it quits, i.e. logically hands over the responsibility to ProcessReadyTask.

Constructor & Destructor Documentation

LogReadyTask()

tarch::multicore::taskfusion::LogReadyTask::LogReadyTask	(	Task *	task,
		int	taskNumber,
		ReadyFusableTasks *	taskQueue )

Construct log read task.

Parameters

task	Task that is to be inserted into fusable queue as soon as this task starts to run
taskNumber	out dependency (no) of outgoing task
taskQueue	Reference to task queue

Member Function Documentation

insertReadyTask()

void tarch::multicore::taskfusion::LogReadyTask::insertReadyTask ( Task * task, int taskNumber, ReadyFusableTasks * taskQueue )

static

Insert a new ready task into the local queues.

Is used by run() but we might also want to use it externally. Before we insert the actual task, we also remove the task's completedTaskNumbers, so noone thinks ahead of time that we are done already.

Here is the caller graph for this function:

run()

void tarch::multicore::taskfusion::LogReadyTask::run ( )

overridevirtual

Run task.

If this routine is invoked, we know that all the incoming dependencies of _task are now complete. We refrain from running the task now (even though it would be valid). Instead, we lock our queue and add the task. translateFusableTaskIntoTaskSequence() should already have issued a follow-up task of type ProcessReadyTask. Therefore, this is all to be done here. No more work.

Implements tarch::multicore::Task.
