Constructor & Destructor Documentation

EpetraExt::MultiMpiComm::MultiMpiComm	(	MPI_Comm	globalComm,
		int	subDomainProcs,
		int	numTimeSteps_ = -1
	)

MultiMpiComm constuctor.

Creates a MultiMpiComm object and communicators for the global and sub- problems.

Parameters:

	In	globalComm - MPI communciator (usually MPI_COMM_WORLD)
	In	subDomainProcss - number of processors in each subdomain. This must divide evenly into the total number of processors of the globalComm.
	In	numTimeSteps (Default=-1) - Piece of partitioning data needed specifically for parallel space-time project, corresponding to the total number of time steps.

EpetraExt::MultiMpiComm::MultiMpiComm	(	const Epetra_MpiComm &	Comm,
		int	numTimeSteps_
	)

MultiMpiComm constuctor, no parallelism over domains.

Creates a MultiMpiComm object for the simple case of no parallelism over multiple steps.

Parameters:

	In	EpetraMpiComm - Epetra_MpiComm communciator
	In	numTimeSteps - Number of steps
