Detailed Description

template<class OrdinalType>
class Teuchos::CommStatus< OrdinalType >

Encapsulation of the result of a receive (blocking or nonblocking).

An instance of this class encapsulates the result of a receive. (An MPI implementation would wrap MPI_Status.) You can query it for information like the rank of the process that sent you the message. (This is useful if your receive specified a negative source rank, indicating that you would accept a message from any process in the communicator.)

Template Parameters

OrdinalType

The same template parameter as Comm. Only use int here. We only make this a template class for compatibility with Comm.

Note

For now, this class only exposes the rank of the process that sent the message (the "source rank") and its tag. Later, we might expose other fields of MPI_Status in this interface. For now, you can attempt a dynamic cast to MpiCommStatus to access all three fields (MPI_SOURCE, MPI_TAG, and MPI_ERROR).
