Constructor & Destructor Documentation
sc::MTMPIMemoryGrp::MTMPIMemoryGrp(constRef<MessageGrp>&msg,constRef<ThreadGrp>&th,MPI_Commcomm=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(constRef<KeyVal>&)
Construct a MTMPIMemoryGrp given a KeyVal input object. A fully thread safe MPI is needed
(MPI_THREAD_MULTIPLE).
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.
Member Function Documentation
voidsc::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.
