Detailed Description

Multiprocessing communication superclass.

vtkMultiProcessController is used to control multiple processes in a distributed computing environment. It has methods for executing single/multiple method(s) on multiple processors, triggering registered callbacks (Remote Methods) (AddRMI(), TriggerRMI()) and communication. Please note that the communication is done using the communicator which is accessible to the user. Therefore it is possible to get the communicator with GetCommunicator() and use it to send and receive data. This is the encouraged communication method. The internal (RMI) communications are done using a second internal communicator (called RMICommunicator).

There are two modes for RMI communication: (1) Send/Receive mode and (2) Broadcast (collective) mode. The Send/Receive mode arranges processes in a binary tree using post-order traversal and propagates the RMI trigger starting from the root (rank 0) to the children. It is commonly employed to communicate between client/server over TCP. Although, the Send/Receive mode can be employed transparently over TCP or MPI, it is not optimal for triggering the RMIs on the satellite ranks. The Broadcast mode provides a more desirable alternative, namely, it uses MPI_Broadcast for communication, which is the nominal way of achieving this in an MPI context. The underlying communication mode used for triggering RMIs is controlled by the "BroadcastTriggerRMI" variable. Note, that mixing between the two modes for RMI communication is not correct behavior. All processes within the vtkMultiProcessController must use the same mode for triggering RMI.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

Reimplemented in vtkMPIController, and vtkSocketController.

◆ Initialize() [1/2]

virtual void vtkMultiProcessController::Initialize	(	int *	vtkNotUsedargc,
		char ***	vtkNotUsedargv
	)

pure virtual

This method is for setting up the processes.

If a subclass needs to initialize process communication (i.e. MPI) it would over ride this method.

◆ Initialize() [2/2]

virtual void vtkMultiProcessController::Initialize	(	int *	vtkNotUsedargc,
		char ***	vtkNotUsedargv,
		int	initializedExternally
	)

pure virtual

This method is for setting up the processes.

If a subclass needs to initialize process communication (i.e. MPI) it would over ride this method. Provided for initialization outside vtk.

Implemented in vtkMPIController.

◆ Finalize() [1/2]

virtual void vtkMultiProcessController::Finalize ( )

pure virtual

This method is for cleaning up.

If a subclass needs to clean up process communication (i.e. MPI) it would over ride this method.

Implemented in vtkMPIController, vtkSocketController, and vtkDummyController.

◆ Finalize() [2/2]

virtual void vtkMultiProcessController::Finalize ( int finalizedExternally )

pure virtual

This method is for cleaning up.

If a subclass needs to clean up process communication (i.e. MPI) it would over ride this method. Provided for finalization outside vtk.

Implemented in vtkSocketController, vtkDummyController, and vtkMPIController.

◆ SetNumberOfProcesses()

void vtkMultiProcessController::SetNumberOfProcesses ( int num )

Set the number of processes you will be using.

This defaults to the maximum number available. If you set this to a value higher than the default, you will get an error.

◆ GetNumberOfProcesses()

int vtkMultiProcessController::GetNumberOfProcesses ( )

Set the number of processes you will be using.

This defaults to the maximum number available. If you set this to a value higher than the default, you will get an error.

◆ SetSingleMethod()

void vtkMultiProcessController::SetSingleMethod	(	vtkProcessFunctionType	,
		void *	data
	)

Set the SingleMethod to f() and the UserData of the for the method to be executed by all of the processes when SingleMethodExecute is called.

All the processes will start by calling this function.

◆ SetSingleProcessObject()

void vtkMultiProcessController::SetSingleProcessObject ( vtkProcess * p )

Object-oriented flavor of SetSingleMethod().

Instead of passing some function pointer and user data, a vtkProcess object is passed where the method to execute is Execute() and the data the object itself.

◆ SingleMethodExecute()

virtual void vtkMultiProcessController::SingleMethodExecute ( )

pure virtual

Execute the SingleMethod (as define by SetSingleMethod) using this->NumberOfProcesses processes.

This will only return when all the processes finish executing their methods.

Implemented in vtkMPIController, vtkSocketController, and vtkDummyController.

◆ SetMultipleMethod()

void vtkMultiProcessController::SetMultipleMethod	(	int	index,
		vtkProcessFunctionType	,
		void *	data
	)

Set the MultipleMethod to f() and the UserData of the for the method to be executed by the process index when MultipleMethodExecute is called.

This is for having each process start with a different function and data argument.

◆ MultipleMethodExecute()

virtual void vtkMultiProcessController::MultipleMethodExecute ( )

pure virtual

Execute the MultipleMethods (as define by calling SetMultipleMethod for each of the required this->NumberOfProcesses methods) using this->NumberOfProcesses processes.

Implemented in vtkMPIController, vtkSocketController, and vtkDummyController.

◆ GetLocalProcessId()

int vtkMultiProcessController::GetLocalProcessId ( )

Tells you which process [0, NumProcess) you are in.

◆ GetGlobalController()

static vtkMultiProcessController* vtkMultiProcessController::GetGlobalController ( )

static

This convenience method returns the controller associated with the local process.

It returns nullptr until the processes are spawned. It is better if you hang on to the controller passed as an argument to the SingleMethod or MultipleMethod functions.

◆ CreateOutputWindow()

virtual void vtkMultiProcessController::CreateOutputWindow ( )

pure virtual

This method can be used to tell the controller to create a special output window in which all messages are preceded by the process id.

Implemented in vtkMPIController, vtkSocketController, and vtkDummyController.

◆ CreateSubController()

virtual vtkMultiProcessController* vtkMultiProcessController::CreateSubController ( vtkProcessGroup * group )

virtual

Creates a new controller with the processes specified by the given group.

The new controller will already be initialized for you. You are responsible for deleting the controller once you are done. It is invalid to pass this method a group with a different communicator than is used by this controller. This operation is collective across all processes defined in the group. It is undefined what will happen if the group is not the same on all processes. This method must be called by all processes in the controller regardless of whether they are in the group. nullptr is returned on all process not in the group.

Reimplemented in vtkMPIController.

◆ PartitionController()

virtual vtkMultiProcessController* vtkMultiProcessController::PartitionController	(	int	localColor,
		int	localKey
	)

virtual

Partitions this controller based on a coloring.

That is, each process passes in a color. All processes with the same color are grouped into the same partition. The processes are ordered by their self-assigned key. Lower keys have lower process ids. Ties are broken by the current process ids. (For example, if all the keys are 0, then the resulting processes will be ordered in the same way.) This method returns a new controller to each process that represents the local partition. This is basically the same operation as MPI_Comm_split.

Reimplemented in vtkMPIController.

◆ AddRMI()

virtual unsigned long vtkMultiProcessController::AddRMI	(	vtkRMIFunctionType	,
		void *	localArg,
		int	tag
	)

virtual

Register remote method invocation in the receiving process which makes the call.

It must have a unique tag as an RMI id. The vtkRMIFunctionType has several arguments: localArg (same as passed in), remoteArg, remoteArgLength (memory passed by process triggering the RMI), remoteProcessId. Since only one callback can be registered per tag, this method will remove any previously registered callback for the given tag. Returns a unique Id for the RMI registration which can be used to unregister the callback. RemoveRMI() should be preferred over RemoveFirstRMI() since it avoid accidental removal of callbacks.

◆ RemoveFirstRMI()

virtual int vtkMultiProcessController::RemoveFirstRMI ( int tag )

virtual

Remove the first RMI matching the tag.

◆ RemoveRMI() [1/2]

virtual int vtkMultiProcessController::RemoveRMI ( unsigned long id )

virtual

Remove the RMI matching the id.

The id is the same id returned by AddRMI().

◆ RemoveRMI() [2/2]

virtual void vtkMultiProcessController::RemoveRMI	(	vtkRMIFunctionType	f,
		void *	arg,
		int	tag
	)

inlinevirtual

Take an RMI away.

Definition at line 228 of file vtkMultiProcessController.h.

◆ AddRMICallback()

virtual unsigned long vtkMultiProcessController::AddRMICallback	(	vtkRMIFunctionType	,
		void *	localArg,
		int	tag
	)

virtual

These methods are a part of the newer API to add multiple rmi callbacks.

When the RMI is triggered, all the callbacks are called Adds a new callback for an RMI. Returns the identifier for the callback.

◆ RemoveAllRMICallbacks()

virtual void vtkMultiProcessController::RemoveAllRMICallbacks ( int tag )
