Detailed Description

MPI tokenizing ensures that not more than N processes execute the same code portion simultaneously.

Usage:

mpi::Tokenizing tokenizing ( 10 );
tokenizing.pre();
criticalFunction(); // maximal 10 processes execute that function simultaneously
tokenizing.post()

#include <Tokenizing.h>
