Detailed Description

Used to send/receive messages in a multiprocess environment.

This is an abstact class which contains functionality for sending and receiving inter-process messages. It contains methods for marshaling an object into a string (currently used by the MPI communicator but not the shared memory communicator).

Warning
Communication between systems with different vtkIdTypes is not supported. All machines have to have the same vtkIdType.

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 vtkObjectBase.

Reimplemented in vtkMPICommunicator, vtkSocketCommunicator, vtkSubCommunicator, and vtkDummyCommunicator.

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 vtkMPICommunicator, vtkSocketCommunicator, vtkSubCommunicator, and vtkDummyCommunicator.

virtual void vtkCommunicator::SetNumberOfProcesses ( int  num)
virtual

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.

Reimplemented in vtkSocketCommunicator.

virtual int vtkCommunicator::GetNumberOfProcesses ( )
virtual

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.

virtual int vtkCommunicator::GetLocalProcessId ( )
virtual

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

int vtkCommunicator::Send ( vtkDataObject data,
int  remoteHandle,
int  tag 
)

This method sends a data object to a destination.

Tag eliminates ambiguity and is used to match sends to receives.

int vtkCommunicator::Send ( vtkDataArray data,
int  remoteHandle,
int  tag 
)

This method sends a data array to a destination.

Tag eliminates ambiguity and is used to match sends to receives.

virtual int vtkCommunicator::SendVoidArray ( const void *  data,
vtkIdType  length,
int  type,
int  remoteHandle,
int  tag 
)
pure virtual

Subclasses have to supply this method to send various arrays of data.

The type arg is one of the VTK type constants recognized by the vtkTemplateMacro (VTK_FLOAT, VTK_INT, etc.). length is measured in number of values (as opposed to number of bytes).

Implemented in vtkSocketCommunicator, vtkMPICommunicator, vtkSubCommunicator, and vtkDummyCommunicator.

The caller does not have to know the data type before this call is made.

Subclasses have to supply this method to receive various arrays of data.

The type arg is one of the VTK type constants recognized by the vtkTemplateMacro (VTK_FLOAT, VTK_INT, etc.). maxlength is measured in number of values (as opposed to number of bytes) and is the maxmum length of the data to receive. If the maxlength is less than the length of the message sent by the sender, an error will be flagged. Once a message is received, use the GetCount() method to determine the actual size of the data received.

Returns the number of words received by the most recent Receive().

Note that this is not the number of bytes received, but the number of items of the data-type received by the most recent Receive() eg. if Receive(int*,..) was used, then this returns the number of ints received; if Receive(double*,..) was used, then this returns the number of doubles received etc. The return value is valid only after a successful Receive().

Gathers vtkDataObject (sendBuffer) from all ranks to the destProcessId.

Parameters
[in]sendBuffer- data object to send from local process. Can be null if not sending any data from the current process.
[out]recvBuffer- vector of data objects to receive data on the receiving rank (identified by destProcessId). This may be empty or filled with data object instances. If empty, data objects will be created as needed. If not empty, existing data object will be used.
[in]destProcessId- process id to gather on.
Returns
- 1 on success, 0 on failure.

Each process (including the source) receives a portion of the send buffer. Process 0 receives the first length values, process 1 receives the second length values, and so on. Scatter is the inverse operation of Gather.

Determine the global bounds for a set of processes.

BBox is initially set (outside of the call to the local bounds of the process and will be modified to be the global bounds - this default implementation views the processors as a heap tree with the root being processId = 0 If either rightHasBounds or leftHasBounds is not 0 then the corresponding int will be set to 1 if the right/left processor has bounds else it will be set to 0 The last three arguments are the tags to be used when performing the operation

static int vtkCommunicator::GetParentProcessor ( int  pid)
static

Some helper functions when dealing with heap tree - based algorthims - we don't need a function for getting the right processor since it is 1 + theLeftProcessor.

Convert a data object into a string that can be transmitted and vice versa.

Same as UnMarshalDataObject(vtkCharArray*, vtkDataObject*) except that this method doesn't need to know the type of the data object a priori.

It can deduce that from the contents of the buffer. May return NULL data object if buffer is NULL or empty.

GatherV collects arrays in the process with id destProcessId.

Each process (including the destination) sends its sendArray to the destination process. The destination process receives the arrays and stores them in rank order in recvArrays. The recvArays is an array containing NumberOfProcesses elements. The recvArray allocates and manages memory for recvArrays.
