Functions

void sierra::mpih::Enable ()
 Member function Enable initializes exception handling.
void sierra::mpih::Keyval_delete (MPI_Comm comm)
void sierra::mpih::Sub_Communicator (MPI_Comm old_comm, MPI_Comm new_comm)
 Member function Sub_Communicator initialize a new communicator from an old one. This is an unusual call in that the communicators have to be explicitly passed. Normally the default communicator is taken as sierra::Fmwk::Env::comm(). Sub_Communicator is used when Env is reset with a partition of communicators. Each of the new sub communicators need to be initialized from the old one. This avoids having to register all of the exception handlers again. The new communicator will inherit everything from the old and even use the same memory to store flags and such.
void sierra::mpih::Register_Handles ()
 Member function Register_Handles is called during creation of this singleton. All of the exception subclasses that can be thrown by Fmwk are registered as handles with the MPIH subsystem.
void sierra::mpih::Add_Handle (const ExParallel &X)
 Member function Add_Handle additional exceptions can be added with Add_Handle. This would be neccessary if an application defined its own exception classes.
void sierra::mpih::Delete_Handles ()
 Member function Delete_Handles deletes all exception handles. Should only be called in destructor.

Detailed Description

Framework interface to MPIH system.

sierra::mpih provides a C++ interface to the C based MPIH system. It handles all of the explicit exception handling and run time type identification that is not possible in C. Sierra applications should not have to call MPIH directly, but should call sierra::mpih.
