Detailed Description

Process communication using MPI.

vtkMPIController is a concrete class which implements the abstract multi-process control methods defined in vtkMultiProcessController using MPI (Message Passing Interface) cf. Using MPI / Portable Parallel Programming with the Message-Passing Interface, Gropp et al, MIT Press. It also provide functionality specific to MPI and not present in vtkMultiProcessController. Before any MPI communication can occur Initialize() must be called by all processes. It is required to be called once, controllers created after this need not call Initialize(). At the end of the program Finalize() must be called by all processes.

The use of user-defined communicators are supported with the CreateSubController method. Note that a duplicate of the user defined communicator is used for internal communications (RMIs). This communicator has the same properties as the user one except that it has a new context which prevents the two communicators from interfering with each other.

Constructor & Destructor Documentation

vtkMPIController::vtkMPIController ( )

protected

When set to 1, TriggerRMI uses Ssend() instead of Send() calls. Off (0) by default.

vtkMPIController::~vtkMPIController ( )

protected

When set to 1, TriggerRMI uses Ssend() instead of Send() calls. Off (0) by default.

Member Function Documentation

static vtkMPIController* vtkMPIController::New ( )

static

static int vtkMPIController::IsTypeOf ( const char * type )

static

virtual int vtkMPIController::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkMultiProcessController.

static vtkMPIController* vtkMPIController::SafeDownCast ( vtkObjectBase * o )

virtual vtkObjectBase* vtkMPIController::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkMultiProcessController.

vtkMPIController* vtkMPIController::NewInstance ( ) const

void vtkMPIController::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 vtkMultiProcessController.

virtual void vtkMPIController::Initialize	(	int *	argc,
		char ***	argv
	)

inlinevirtual

This method is for setting up the processes. It needs to be called only once during program execution. Calling it more than once will have no effect. Controllers created after this call will be initialized automatically (i.e. they will have the proper LocalProcessId and NumberOfProcesses). The addresses of argc and argv should be passed to this method otherwise command line arguments will not be correct (because usually MPI implementations add their own arguments during startup).

Definition at line 78 of file vtkMPIController.h.

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

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.

Implements vtkMultiProcessController.

virtual void vtkMPIController::Initialize ( )

virtual

Same as Initialize(0, 0, 1). Mainly for calling from wrapped languages.

virtual void vtkMPIController::Finalize ( )

inlinevirtual

This method is for cleaning up and has to be called before the end of the program if MPI was initialized with Initialize()

Implements vtkMultiProcessController.

Definition at line 91 of file vtkMPIController.h.

virtual void vtkMPIController::Finalize ( int finalizedExternally )

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.

Implements vtkMultiProcessController.

virtual void vtkMPIController::SingleMethodExecute ( )

virtual

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

Implements vtkMultiProcessController.

virtual void vtkMPIController::MultipleMethodExecute ( )

virtual

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

Implements vtkMultiProcessController.

virtual void vtkMPIController::CreateOutputWindow ( )

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.

Implements vtkMultiProcessController.

static char* vtkMPIController::ErrorString ( int err )

static

Given an MPI error code, return a string which contains an error message. This string has to be freed by the user.

void vtkMPIController::SetCommunicator ( vtkMPICommunicator * comm )

MPIController uses this communicator in all sends and receives. By default, MPI_COMM_WORLD is used. THIS SHOULD ONLY BE CALLED ON THE PROCESSES INCLUDED IN THE COMMUNICATOR. FOR EXAMPLE, IF THE COMMUNICATOR CONTAINS PROCESSES 0 AND 1, INVOKING THIS METHOD ON ANY OTHER PROCESS WILL CAUSE AN MPI ERROR AND POSSIBLY LEAD TO A CRASH.

virtual vtkMPIController* vtkMPIController::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. NULL is returned on all process not in the group.

Reimplemented from vtkMultiProcessController.

virtual vtkMPIController* vtkMPIController::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 from vtkMultiProcessController.

int vtkMPIController::NoBlockSend	(	const int *	data,
		int	length,
		int	remoteProcessId,
		int	tag,
		vtkMPICommunicator::Request &	req
	)

inline

This method sends data to another process (non-blocking). Tag eliminates ambiguity when multiple sends or receives exist in the same process. The last argument, vtkMPICommunicator::Request& req can later be used (with req.Test() ) to test the success of the message. Return values are 1 for success and 0 otherwise. Note: These methods delegate to the communicator
