In this review paper we are going to address an issue in the simulation of lattice gauge theory, is that the distribution of gauge configurations over different topological sectors. These different topological regions are characterized by topological charge (Q). The distribution of Q becomes more and more difficult as the continuum limit (lattice spacing goes to zero) is approached. As a consequence, autocorrelation times of physical quantities like Q grows rapidly making the calculation of expectation values time consuming and it may sometime does not produce the expected results of the simulation. Without periodic an open boundary condition on the gauge field in the temporal direction has been recently proposed to overcome the spanning or distribution problem of Q. In this review paper, the interesting observables to study are Q and the topological susceptibility and lowest glueball (scalar) mass using open and periodic boundary conditions.
