Detailed Description

Interface of the message passing manager.

This class uses a semantic by reference and instances are automatically destroyed when needed.

Most of the operations on this class use free functions (like mpSend() or mpReceive()) which are defined in file 'Messages.h'.

Arcane provides several implementation for message passing, using MPI, shared memory message passing or hybrid (MPI + shared memory) message passing. When using MPI, it is possible to create an instance of this class using the class StandaloneMpiMessagePassingMng.

Member Function Documentation

communicator()

Communicator Arcane::MessagePassing::IMessagePassingMng::communicator ( ) const

virtual

MPI communicator associated with this instance.

The communicator is only valid if the instance is associated with an MPI implementation. You can convert a communicator to a MPI communicator using helper methods toMpiCommunicator() and fillMpiCommunicatorIfValid() or like that:

IMessagePassingMng* mpm = ...;
Communicator comm = mpm->communicator();
if (comm.isValid())
  MPI_Comm mpi_comm = static_cast<MPI_Comm>(comm).

mpDelete

void mpDelete ( IMessagePassingMng * p )

friend

Destroys the message passing instance p.

Warning

This should only be used when using deprecated functions which do not return instances of Ref<IMessagePassingMng> and instead only return a IMessagePassingMng*.
