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).

void vtkMultiProcessController::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`

Methods invoked by print to print information about the object including superclasses. 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 vtkDummyController, vtkMPIController, and vtkSocketController.

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.

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.

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 vtkDummyController, vtkMPIController, and vtkSocketController.

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 vtkDummyController, vtkMPIController, and vtkSocketController.

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.

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.

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.

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.

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 vtkDummyController, vtkMPIController, and vtkSocketController.

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.

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 vtkDummyController, vtkMPIController, and vtkSocketController.

int vtkMultiProcessController::GetLocalProcessId ( )

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

Reimplemented in vtkDummyController.

static vtkMultiProcessController* vtkMultiProcessController::GetGlobalController ( ) [static]

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

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 vtkDummyController, vtkMPIController, and vtkSocketController.

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 accross 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. NULL is returned on all process not in the group.

Reimplemented in vtkMPIController.

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.

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

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.

int vtkMultiProcessController::RemoveFirstRMI ( int tag )

Remove the first RMI matching the tag.

int vtkMultiProcessController::RemoveRMI ( unsigned long id )

Remove the RMI matching the id. The id is the same id returned by AddRMI().

void vtkMultiProcessController::RemoveRMI	(	vtkRMIFunctionType	f,
		void *	arg,
		int	tag
	)			`[inline]`

Take an RMI away.

Definition at line 204 of file vtkMultiProcessController.h.

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

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.

void vtkMultiProcessController::RemoveAllRMICallbacks ( int tag )

These methods are a part of the newer API to add multiple rmi callbacks. When the RMI is triggered, all the callbacks are called Removes all callbacks for the tag.

bool vtkMultiProcessController::RemoveRMICallback ( unsigned long id )

Remove a callback. Returns true is the remove was successful.

void vtkMultiProcessController::TriggerRMI	(	int	remoteProcessId,
		void *	arg,
		int	argLength,
		int	tag
	)

A method to trigger a method invocation in another process.

void vtkMultiProcessController::TriggerBreakRMIs ( )

A conveniance method. Called on process 0 to break "ProcessRMIs" loop on all other processes.

void vtkMultiProcessController::TriggerRMI	(	int	remoteProcessId,
		const char *	arg,
		int	tag
	)			`[inline]`

Convenience method when the arg is a string.

Definition at line 233 of file vtkMultiProcessController.h.

void vtkMultiProcessController::TriggerRMI	(	int	remoteProcessId,
		int	tag
	)			`[inline]`

Convenience method when there is no argument.

Definition at line 240 of file vtkMultiProcessController.h.

void vtkMultiProcessController::TriggerRMIOnAllChildren	(	void *	arg,
		int	argLength,
		int	tag
	)

This is a convenicence method to trigger an RMI call on all the "children" of the current node. The children of the current node can be determined by drawing a binary tree starting at node 0 and then assigned nodes ids incrementally in a breadth-first fashion from left to right. This is designed to be used when trigger an RMI call on all satellites from the root node.

void vtkMultiProcessController::TriggerRMIOnAllChildren	(	const char *	arg,
		int	tag
	)			`[inline]`

This is a convenicence method to trigger an RMI call on all the "children" of the current node. The children of the current node can be determined by drawing a binary tree starting at node 0 and then assigned nodes ids incrementally in a breadth-first fashion from left to right. This is designed to be used when trigger an RMI call on all satellites from the root node.

The children of the current node can be determined by drawing a binary tree starting at node 0 and then assigned nodes ids incrementally in a breadth-first fashion from left to right. This is designed to be used when trigger an RMI call on all satellites from the root node.

Definition at line 257 of file vtkMultiProcessController.h.

int vtkMultiProcessController::ProcessRMIs	(	int	reportErrors,
		int	dont_loop = `0`
	)

Calling this method gives control to the controller to start processing RMIs. Possible return values are: RMI_NO_ERROR, RMI_TAG_ERROR : rmi tag could not be received, RMI_ARG_ERROR : rmi arg could not be received. If reportErrors is false, no vtkErrorMacro is called. ProcessRMIs() calls ProcessRMIs(int) with reportErrors = 0. If dont_loop is 1, this call just process one RMI message and exits.

int vtkMultiProcessController::ProcessRMIs ( )

Calling this method gives control to the controller to start processing RMIs. Possible return values are: RMI_NO_ERROR, RMI_TAG_ERROR : rmi tag could not be received, RMI_ARG_ERROR : rmi arg could not be received. If reportErrors is false, no vtkErrorMacro is called. ProcessRMIs() calls ProcessRMIs(int) with reportErrors = 0. If dont_loop is 1, this call just process one RMI message and exits.

virtual void vtkMultiProcessController::SetBreakFlag ( int ) [virtual]

Setting this flag to 1 will cause the ProcessRMIs loop to return. This also causes vtkUpStreamPorts to return from their WaitForUpdate loops.

virtual int vtkMultiProcessController::GetBreakFlag ( ) [virtual]

Setting this flag to 1 will cause the ProcessRMIs loop to return. This also causes vtkUpStreamPorts to return from their WaitForUpdate loops.

virtual vtkCommunicator* vtkMultiProcessController::GetCommunicator ( ) [virtual]

Returns the communicator associated with this controller. A default communicator is created in constructor.

Reimplemented in vtkDummyController.

ScatterV is the vector variant of Scatter. It extends the functionality of Scatter by allowing a varying count of data to each process. ScatterV takes an array in the process with id srcProcessId and distributes it. Each process (including the source) receives a portion of the send buffer defined by the sendLengths and offsets arrays.
