A call to MPI_INIT or MPI_THREAD_INIT, from any language,
initializes MPI-/ for execution in all languages.
-
- Advice to users.
Certain implementations use the (inout) argc, argv arguments of the
C/C++ version
of MPI_INIT in order to propagate values for argc and
argv to all
executing processes.
Use of the Fortran
version of MPI_INIT to initialize MPI-/ may result in a loss
of this ability.(End of advice to users.)
The function MPI_INITIALIZED returns the same answer in all
languages.
The function MPI_FINALIZE finalizes
the MPI-/
environments for all languages.
The function MPI_FINALIZED returns the same answer in all
languages.
The function MPI_ABORT kills processes, irrespective of the language
used
by the caller or by the processes killed.
The MPI-/ environment is initialized in the same manner for all languages by
MPI_INIT.
E.g., MPI_COMM_WORLD carries the same information regardless
of language: same processes, same environmental attributes,
same error handlers.
Information can be added to info objects in one language and
retrieved in another.

- Advice to users.
The use of several languages in one MPI-/ program may require the use
of special options at compile and/or link time.(End of advice to users.)
-
- Advice
to implementors.
Implementations may selectively link language specific MPI-/ libraries
only to codes that need them, so as not to increase the size of
binaries for codes that use only one language.
The MPI-/ initialization code need perform initialization for a language
only if that language library is loaded.(End of advice to implementors.)
