+@subsection SMPI_what_globals Privatization of global variables
Concerning the globals, the problem comes from the fact that usually,
MPI processes run as real UNIX processes while they are all folded
our implementation was not robust enough to be used in production, so
it was removed at some point. Currently, SMPI comes with two
privatization mechanisms that you can @ref options_smpi_privatization
