Member Function Documentation

Ref<StateSend> sc::ActiveMessageGrp::get_statesend

(

)

Each thread using the ActiveMessageGrp needs its own StateSend object.

This cannot be called concurrently by multiple threads.

void sc::ActiveMessageGrp::send	(	int	node,
		const Ref< StateSend > &	,
		const Ref< ActiveMessage > &
	)

Send the active message to node.

The give StateOut must not be concurrently used by any other thread. This member can be called concurrently by multiple threads.

void sc::ActiveMessageGrp::activate

(

)

Make the object ready to process messages.

This will also synchronizes the nodes. This must be called by only one thread.

void sc::ActiveMessageGrp::deactivate

(

)

Processes all outstanding messages and disable processing of messages.

This will also synchronize the processes. This must be called by only one thread.

void sc::ActiveMessageGrp::sync

(

)

Synchronize all of the processes in this group.

Ref<MessageGrp> sc::ActiveMessageGrp::messagegrp

(

)

[inline]

Return the MessageGrp used to implement the ActiveMessageGrp.
