Detailed Description

Used to send/receive messages in a multiprocess environment.

This is an abstract 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.

◆ ReceiveVoidArray()

virtual int vtkCommunicator::ReceiveVoidArray ( void *  data,
vtkIdType  maxlength,
int  type,
int  remoteHandle,

pure virtual

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.

Implemented in vtkDummyCommunicator, vtkSocketCommunicator, vtkSubCommunicator, and vtkMPICommunicator.

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.

int  destProcessId 
)

For the first GatherV variant, recvLengths and offsets known on destProcessId and are passed in as parameters For the second GatherV variant, recvLengths and offsets are not known on destProcessId.

The recvLengths is set using a gather operation and offsets is computed from recvLengths. recvLengths has NumberOfProcesses elements and offsets has NumberOfProcesses + 1 elements. The third variant is the same as the second variant but it does not expose recvLength and offsets

◆ GatherV() [17/18]

int vtkCommunicator::GatherV ( vtkDataObject sendData,

Collects data objects in the process with id destProcessId.

Each process (including the destination) marshals and then sends the data object to the destination process. The destination process unmarshals and then stores the data objects in rank order. The recvData (on the destination process) must be of length numProcesses.

Gathers vtkDataObject (sendBuffer) from all ranks to all raks.

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. 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.
Returns
