Detailed Description

Moves/redistributes data between processes.

This class combines all the duplicate and collection requirements into one filter. It can move polydata and unstructured grid between processes. It can redistributed polydata from M to N processors.

Use this method to initialize all communicators/sockets using ParaView defaults.

void vtkMPIMoveData::SetController ( vtkMultiProcessController * controller )

Objects for communication. The controller is an MPI controller used to communicate between processes within one server (render or data). The client-data server socket controller is set on the client and data server and is used to communicate between the two. MPIMToNSocetConnection is set on the data server and render server when we are running with a render server. It has multiple sockets which are used to send data from the data server to the render server. ClientDataServerController==0 => One MPI program. MPIMToNSocketConnection==0 => Client-DataServer. MPIMToNSocketConnection==1 => Client-DataServer-RenderServer.

void vtkMPIMoveData::SetServerToClient ( ) [inline]

Tell the object on which client/server it resides. Whether the sockets are set helps determine which servers are running.

virtual void vtkMPIMoveData::SetMoveMode ( int ) [virtual]

Specify how the data is to be redistributed.

virtual void vtkMPIMoveData::SetOutputDataType ( int ) [virtual]

Controls the output type. This is required because processes receiving data cannot know their output type in RequestDataObject without communicating with other processes. Since communicating with other processes in RequestDataObject is dangerous (can cause deadlock because it may happen out-of-sync), the application has to set the output type. The default is VTK_POLY_DATA. Currently, only VTK_UNSTRUCTURED_GRID and VTK_POLY_DATA are supported. Make sure to call this before any pipeline updates occur.

virtual int vtkMPIMoveData::GetOutputDataType ( ) [virtual]

Controls the output type. This is required because processes receiving data cannot know their output type in RequestDataObject without communicating with other processes. Since communicating with other processes in RequestDataObject is dangerous (can cause deadlock because it may happen out-of-sync), the application has to set the output type. The default is VTK_POLY_DATA. Currently, only VTK_UNSTRUCTURED_GRID and VTK_POLY_DATA are supported. Make sure to call this before any pipeline updates occur.

virtual void vtkMPIMoveData::SetDeliverOutlineToClient ( int ) [virtual]

Sometimes, the data may be too huge to deliver to the client. In that case, the client can request that only the outline for the data may be delivered to the client. This is supported only for vtkPolyData. Off by default.

virtual int vtkMPIMoveData::GetDeliverOutlineToClient ( ) [virtual]

Sometimes, the data may be too huge to deliver to the client. In that case, the client can request that only the outline for the data may be delivered to the client. This is supported only for vtkPolyData. Off by default.

static void vtkMPIMoveData::SetUseZLibCompression ( bool b ) [static]

When set to true, zlib compression is used. False by default. This value has any effect only on the data-sender processes. The receiver always checks the received data to see if zlib decompression is required.

static bool vtkMPIMoveData::GetUseZLibCompression ( ) [static]

When set to true, zlib compression is used. False by default. This value has any effect only on the data-sender processes. The receiver always checks the received data to see if zlib decompression is required.
