Detailed Description

Epetra_SerialDistributor: The Epetra Serial implementation of the Epetra_Distributor Gather/Scatter Setup Class.

The Epetra_SerialDistributor class is an Serial implement of Epetra_Distributor that is essentially a trivial class since a serial machine is a trivial parallel machine. An Epetra_SerialDistributor object is actually produced by calling a method in the Epetra_SerialComm class.

int Epetra_SerialDistributor::CreateFromSends ( const int &  NumExportIDs, const int *  ExportPIDs, bool  Deterministic, int &  NumRemoteIDs  )

virtual

Create Distributor object using list of process IDs to which we export.

Take a list of Process IDs and construct a plan for efficiently scattering to these processes. Return the number of IDs being sent to me.

Parameters
