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.

		const int *	RemoteGIDs,
		const int *	RemotePIDs,
		bool	Deterministic,

	)		[virtual]

Create Distributor object using list of Remote global IDs and corresponding PIDs.

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

Parameters:

NumRemoteIDs	In Number of IDs this processor will be receiving.
RemoteGIDs	In List of IDs that this processor wants.
RemotePIDs	In List of processors that will send the remote IDs.
Deterministic	In No op.
NumExportIDs	Out Number of IDs that need to be sent from this processor.
ExportPIDs	Out List of processors that will get the exported IDs.

Implements Epetra_Distributor.

	)		[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:

NumExportIDs	In Number of IDs that need to be sent from this processor.
ExportPIDs	In List of processors that will get the exported IDs.
Deterministic	In No op.
NumRemoteIDs	Out Number of IDs this processor will be receiving.
