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.

Typedefs
using	tarch::multicore::TaskNumber = int

Enumerations
enum class	tarch::multicore::TaskWaitType { tarch::multicore::Mixed , tarch::multicore::ExclusivelyFusedTasks , tarch::multicore::OnlyNativeTasks }
	This is a hint type which can be used to accelerate any taskwaits. More...

Functions

	Construct string representation.
void	tarch::multicore::initSmartMPI ()
	Switch on SmartMPI.

void	tarch::multicore::spawnTask (Task *task, const std::set< TaskNumber > &inDependencies=tarch::multicore::NoInDependencies, const TaskNumber &taskNumber=tarch::multicore::NoOutDependencies)
	Spawns a single task in a non-blocking fashion.
void	tarch::multicore::waitForTasks (const std::set< TaskNumber > &inDependencies, TaskWaitType taskWaitType=TaskWaitType::Mixed)
	Wait for set of tasks.
void	tarch::multicore::waitForTask (const int taskNumber, TaskWaitType taskWaitType=TaskWaitType::Mixed)
	Wrapper around waitForTasks() with a single-element set.
void	tarch::multicore::spawnAndWait (const std::vector< Task * > &tasks)
	Fork-join task submission pattern.
void	tarch::multicore::native::spawnAndWaitAsTaskLoop (const std::vector< tarch::multicore::Task * > &tasks)
	Map onto native tasking.
void	tarch::multicore::native::spawnTask (Task *task, const std::set< TaskNumber > &inDependencies, const TaskNumber &taskNumber)
	Spawn a new task into the tasking backend.
void	tarch::multicore::native::waitForTasks (const std::set< TaskNumber > &inDependencies)
	Wait for other task.
void	tarch::multicore::native::waitForAllTasks ()
	Slightly different than the umbrella version in the general namespace.
void	tarch::multicore::waitForAllTasks ()
	Wait for all tasks notably has to take fused tasks into account.
