Reason to add:
#105 reports a failure from FujitsuMPI occurred when calling
MPI_T_cvar_writeat OSHMPI init. It looks like FujitsuMPI does not return a proper error at the call toMPI_T_cvar_get_index.MPI_T_ERR_INVALID_NAMEis expected when an MPI implementation specific CVAR does not exist.This PR provides a workaround from OSHMPI. More checks need to be done with FujitsuMPI
