NAME
       sc::MTMPIMemoryGrp - This MemoryGrp class requires a MT-safe MPI
       implementation.

SYNOPSIS
       #include	<memmtmpi.h>

       Inherits	sc::ActiveMsgMemoryGrp.

   Public Member Functions
       MTMPIMemoryGrp (const Ref< MessageGrp > &msg, const Ref<	ThreadGrp >
	   &th,	MPI_Comm comm=MPI_COMM_WORLD)
	   Construct a MTMPIMemoryGrp given a MessageGrp, ThreadGrp, and an
	   MPI communicator.
       MTMPIMemoryGrp (const Ref< KeyVal > &)
	   Construct a MTMPIMemoryGrp given a KeyVal input object.
       void activate ()
	   Activate is called before the memory	is to be used.
       void deactivate ()
	   Deactivate is called	after the memory has been used.
       void sync ()
	   Synchronizes	all the	nodes.

Detailed Description
       This MemoryGrp class requires a MT-safe MPI implementation.

       The default MessageGrp must be a	MPIMessageGrp. MPI must	be safe	with
       respect to the default ThreadGrp. Alternately, a	MessageGrp and a
       ThreadGrp can be	passed to the constructor.

Constructor & Destructor Documentation
   sc::MTMPIMemoryGrp::MTMPIMemoryGrp (const Ref< MessageGrp > & msg, const
       Ref< ThreadGrp >	& th, MPI_Comm comm = MPI_COMM_WORLD)
       Construct a MTMPIMemoryGrp given	a MessageGrp, ThreadGrp, and an	MPI
       communicator. The communicator can be a subset of MPI_COMM_WORLD, in
       which case, the MessageGrp must refer to	the same subset.

   sc::MTMPIMemoryGrp::MTMPIMemoryGrp (const Ref< KeyVal > &)
       Construct a MTMPIMemoryGrp given	a KeyVal input object. A fully thread
       safe MPI	is needed (MPI_THREAD_MULTIPLE).

Member Function	Documentation
   void	sc::MTMPIMemoryGrp::sync () [virtual]
       Synchronizes all	the nodes. This	is useful after	remote memory writes
       to be certain that all of the writes have completed and the data	can be
       accessed	locally, for example.

       Reimplemented from sc::MsgMemoryGrp.
