Implementation that can be reused by driver writers.

Independent of Ccafe internals.

Constructor & Destructor Documentation

neo::support::MPISetup::MPISetup ( )

void neo::support::MPISetup::initialize	(	MPI_Comm	borrowComm,
		MPI_Comm	dupComm,
		neo::cca::AbstractFramework *	naf
	)

Create and add to the framework MPIService and MPIBorrow support services.

This will appear in the frame as an MPISetup component. MPI_Init must have been called before this is called.

Parameters:

borrowComm	the shared communicator for those using MPIBorrow.
dupComm	the communicator to duplicate for those using MPIService.
naf	The frame into which the services will be added.

void neo::support::MPISetup::finalize ( bool reclaim )

Shutdown the previous mpi-related services.

Parameters:

reclaim if reclaim true, try to release communicator resources allocated in MPIService support. Otherwise, lose them.
