We calculated the properties of a single flexible polymer chain adsorbed onto a planar surface with two types of nodes, denoted by letters A and B by Monte Carlo methods. One A-type node contacting to the surface has an attractive interaction of strength E=-1. One node of B-type has no affinity for the surface, E= 0. The polymer chain is modeled as a self-avoiding walk of N steps started at the center of the flat surface on the cubic lattice. Statistical properties of the polymer chain are computed by using message passing libraries. We obtain linear speedup by parallel computing the independent samples.
