Public Member Functions
	RectMulticastStrategy (CkMigrateMessage *m)
	RectMulticastStrategy (CkArrayID aid)
	Array constructor.
	~RectMulticastStrategy ()
virtual void	insertMessage (CharmMessageHolder *msg)
virtual void	doneInserting ()
	Called after all messages have been deposited in this processor.
virtual void	handleMessage (void *msg)
	Called by the converse handler function.
virtual void	handleMessageForward (void *msg)
virtual void	pup (PUP::er &p)
virtual void	beginProcessing (int nelements)
	PUPable_decl (RectMulticastStrategy)
Protected Member Functions
unsigned int	computeKey (int sectionID, int srcPe, CkArrayID arrId)
unsigned int	computeKey (int sectionID, int srcPe, int id)
void	insertSectionID (CkSectionID *sid)
	Add this section to the hash table locally.
virtual ComlibRectSectionHashObject *	createObjectOnSrcPe (int nindices, CkArrayIndex *idx_list, unsigned int sectionid)
	Called when a new section multicast is called by the user locally.
virtual ComlibRectSectionHashObject *	createObjectOnIntermediatePe (int nindices, CkArrayIndex idxlist, int npes, ComlibMulticastIndexCount counts, int srcpe, int sectionID)
	Similar to createHashObjectOnSrcPe, but that this call is made on the destination or intermediate processor.
virtual int	needSorting ()
	Needed for getNewMulticastMessage, to specify if the list of processors need to be ordered.
void	localMulticast (envelope env, ComlibRectSectionHashObject obj)
	Called to multicast the message to local array elements.
virtual void	remoteMulticast (envelope env, ComlibRectSectionHashObject obj)
	Called to send to message out to the remote destinations.
virtual void	forwardMulticast (envelope env, ComlibRectSectionHashObject obj)
	Called to forward to someone who can do the heavy sending work.
void	handleNewMulticastMessage (envelope *env)
	Process a new message by extracting the array elements from it and creating a new hash object by calling createObjectOnIntermediatePe().
void	sendRectDest (ComlibRectSectionHashObject obj, int srcpe, envelope env)
BGTsRC_Geometry_t *	getRectGeometry (ComlibRectSectionHashObject *obj, int srcpe)
int	assignCornerRoot (BGTsRC_Geometry_t *geom, int srcpe)
Protected Attributes

	Array section support.
Private Member Functions
	RectMulticastStrategy (CkMigrateMessage *m)
	~RectMulticastStrategy ()
void	insertMessage (MessageHolder *)
	Called for each message.
void	handleMessage (void *)
	Called when a message is received in the strategy handler.
void	pup (PUP::er &p)
	PUPable_decl (RectMulticastStrategy)

Detailed Description

Main class for multicast strategies.

It defaults to sending a direct message to all the processors involved in the multicast.

The definition of the section, as well as the location of all the elements in the processors is determined by the sending processor. The other will obey to it, even some elements have already migrated elsewhere.
