BOOST_MPI_HAS_NOARG_INITIALIZATION — Determine if the MPI implementation has supports initialization without command-line arguments.
// In header: <boost/mpi/config.hpp>
BOOST_MPI_HAS_NOARG_INITIALIZATIONThis macro will be defined when the underlying implementation supports initialization of MPI without passing along command-line arguments, e.g., MPI_Init(NULL, NULL). When defined, the environment class will provide a default constructor. This macro is always defined for MPI-2 implementations.
