Member Function Documentation

◆ borrowComm()

virtual MPI_Comm classic::gov::cca::MPIBorrow::borrowComm	(	int	tagCount,
		int *	tagList,
		int &	key
	)

virtual

Get a communicator of the port provider.

This communicator will be the same instance as the comm of the port provider, with all the message collision potential that implies. Instances which have a comm covering only a subset of themselves may return MPI_COMM_NULL on their "un-covered" processes.

Parameters

tagCount	Input: The number of tags the borrower wishes to use all to itself.
tagList	Output: Array to be filled with tags available. The array given is tagCount long.
key	Output: key to be returned when the tags and comm are done with.

Returns: The comm being borrowed.

◆ returnComm()

virtual void classic::gov::cca::MPIBorrow::returnComm	(	MPI_Comm	,
		int	tagCount,
		int *	tagList,
		int	key
	)
