/*@
MPI_Init_thread - Initialize the MPI execution environment
Input Parameters:
+ argc - Pointer to the number of arguments
. argv - Pointer to the argument vector
- required - Level of desired thread support
Output Parameter:
. provided - Level of provided thread support
Command line arguments:
MPI specifies no command-line arguments but does allow an MPI
implementation to make use of them. See 'MPI_INIT' for a description of
the command line arguments supported by 'MPI_INIT' and 'MPI_INIT_THREAD'.
Notes:
The valid values for the level of thread support are\:
+ MPI_THREAD_SINGLE - Only one thread will execute.
. MPI_THREAD_FUNNELED - The process may be multi-threaded, but only the main
thread will make MPI calls (all MPI calls are funneled to the
main thread).
. MPI_THREAD_SERIALIZED - The process may be multi-threaded, and multiple
threads may make MPI calls, but only one at a time: MPI calls are not
made concurrently from two distinct threads (all MPI calls are serialized).
- MPI_THREAD_MULTIPLE - Multiple threads may call MPI, with no restrictions.
Notes for Fortran:
Note that the Fortran binding for this routine does not have the 'argc' and
'argv' arguments. ('MPI_INIT_THREAD(required, provided, ierror)')

MPI_Init - Initialize the MPI execution environment
Input Parameters:
+ argc - Pointer to the number of arguments
- argv - Pointer to the argument vector
Thread and Signal Safety:
This routine must be called by one thread only. That thread is called
the `main thread` and must be the thread that calls 'MPI_Finalize'.
Notes:
The MPI standard does not say what a program can do before an 'MPI_INIT' or
after an 'MPI_FINALIZE'. In the MPICH implementation, you should do
as little as possible. In particular, avoid anything that changes the
external state of the program, such as opening files, reading standard
input or writing to standard output.
Notes for Fortran:
The Fortran binding for 'MPI_Init' has only the error return
