Namespaces
namespace	tarch
	Have to include this header, as I need access to the SYCL_EXTERNAL keyword.
namespace	tarch::multicore
	This page describes Peano 4's multithreading namespace.
namespace	tarch::multicore::taskfusion
	Task fusion means that a set of tasks are grabbed and mapped onto one large physical tasks instead of being processed one by one.

Functions
void	tarch::multicore::taskfusion::handleFusableTask (Task *task, std::set< TaskNumber > inDependencies, const TaskNumber &taskNumber)
	Handle one fusable task.
void	tarch::multicore::taskfusion::processAllReadyTasks ()
	Run over all known queues and invoke drainReadyTasks() on each one.
void	tarch::multicore::taskfusion::processAndFuseAllReadyTasks ()
	Drain the queues but use task fusion where possible.
void	tarch::multicore::taskfusion::handleFusableTask_ProducerConsumerTaskSequence (Task *task, FusableTasksQueue &taskQueue, std::set< TaskNumber > inDependencies, const TaskNumber &taskNumber, const tarch::multicore::orchestration::Strategy::FuseInstruction &fuseInstruction)
	Realisation for handleFusableTask() for ProducerConsumerTaskSequence.
void	tarch::multicore::taskfusion::handleFusableTask_LazyEvaluation (Task *task, FusableTasksQueue &taskQueue, std::set< TaskNumber > inDependencies, const TaskNumber &taskNumber, const tarch::multicore::orchestration::Strategy::FuseInstruction &fuseInstruction)
	Implementation of handleFusableTask() if we use LazyEvaluation.
void	tarch::multicore::taskfusion::handleFusableTask_EagerConsumerTasks (Task *task, FusableTasksQueue &taskQueue, std::set< TaskNumber > inDependencies, const TaskNumber &taskNumber, const tarch::multicore::orchestration::Strategy::FuseInstruction &fuseInstruction)
	Handle a task in the eager consumer pattern.
bool	tarch::multicore::taskfusion::ensureHeldBackTasksAreMappedOntoNativeTasks (const std::set< TaskNumber > &taskNumbers)
	Ensure that a certain set of tasks is mapped onto native tasks already.
bool	tarch::multicore::taskfusion::ensureHeldBackTasksAreMappedOntoNativeTasks_LazyEvaluation (const std::set< TaskNumber > &inDependencies)
	Preamble of waitForTasks() and task spawns if we use LazyEvaluation.
bool	tarch::multicore::taskfusion::ensureHeldBackTasksAreMappedOntoNativeTasks_EagerConsumerTasks (const std::set< TaskNumber > &inDependencies)
	Preamble of waitForTasks() if we use EagerEvaluation.

Variables
const std::string	tarch::multicore::taskfusion::DirectlyInsertFusedTaskIntoReadyQueueStatisticsIdentifier
	Track how many tasks are directly inserted into ready queue.
const std::string	tarch::multicore::taskfusion::MapFusedTaskOntoNativeTaskStatisticsIdentifier
	Track number of fused tasks that are mapped directly onto native tasks.
const std::string	tarch::multicore::taskfusion::ProcessFusedTaskDirectlyStatisticsIdentifier
	Track number of tasks that are executed directly.
