Detailed Description

A class for performing multithreaded execution with a thread pool back end, uses the Intel Threading Building Blocks (TBB) library.

This multi-threader implementation generates dynamically-sized thread-regions, and is expected to provide best performance.

Member Function Documentation

virtual::itk::LightObject::Pointer itk::TBBMultiThreader::CreateAnother ( ) const

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

virtual const char* itk::TBBMultiThreader::GetNameOfClass ( ) const

virtual

Run-time type information (and related methods).

Reimplemented from itk::MultiThreaderBase.

static Pointer itk::TBBMultiThreader::New ( )

static

Method for creation through the object factory.

void itk::TBBMultiThreader::ParallelizeArray	(	SizeValueType	firstIndex,
		SizeValueType	lastIndexPlus1,
		ArrayThreadingFunctorType	aFunc,
		ProcessObject *	filter
	)

overridevirtual

Parallelize an operation over an array. If filter argument is not nullptr, this function will update its progress as each index is completed.

Reimplemented from itk::MultiThreaderBase.

void itk::TBBMultiThreader::ParallelizeImageRegion	(	unsigned int	dimension,
		const IndexValueType	index[],
		const SizeValueType	size[],
		ThreadingFunctorType	funcP,
		ProcessObject *	filter
	)

overridevirtual

Break up region into smaller chunks, and call the function with chunks as parameters.

Reimplemented from itk::MultiThreaderBase.

void itk::TBBMultiThreader::PrintSelf	(	std::ostream &	os,
		Indent	indent
	)		const

overrideprotectedvirtual

The number of work units to create.

Reimplemented from itk::MultiThreaderBase.

virtual void itk::TBBMultiThreader::SetNumberOfWorkUnits ( ThreadIdType numberOfWorkUnits )

overridevirtual

Get/Set the number of work units to create. TBBMultiThreader does not limit the number of work units. This number is only respected by SetSingleMethod/SingleMethodExecute.

Reimplemented from itk::MultiThreaderBase.

void itk::TBBMultiThreader::SetSingleMethod	(	ThreadFunctionType	,
		void *	data
	)

overridevirtual

Set the SingleMethod to f() and the UserData field of the WorkUnitInfo that is passed to it will be data. This method must be of type itkThreadFunctionType and must take a single argument of type void.

Implements itk::MultiThreaderBase.

void itk::TBBMultiThreader::SingleMethodExecute ( )

overridevirtual

Execute the SingleMethod (as define by SetSingleMethod) using m_NumberOfWorkUnits work units. As a side effect the m_NumberOfWorkUnits will be checked against the current m_GlobalMaximumNumberOfThreads and clamped if necessary.

Implements itk::MultiThreaderBase.
