OpenMP numthreads option with MC simulations

OpenMP numthreads:
While performing a MC simulation I tried to change the number of threads used, but the speed was never affected [using 0,1,4 or 8]. In fact it seems that Hippo uses the maximum number of threads available on one node regardless the value of 'OpenMP numthreads'. Also, when I tested Hippo on a dual quadcore CPU, the computational time was the same as the one on a single quadcore CPU (using OpenMP numthreads = 0). Is the number of threads used only limited to one core (i.e. 4 CPUs here)?

Sorry, MC is not parallelized yet. the openMP numthreads is only for MD simulations. MC will be parallelized in the future.
