One problem of mechanics is solved in this paper by means of parallel computing. More precisely, in this paper one can find a description of the analysis of a mechanical system composed of rigid bodies and unilateral constrains. This analysis is performed with the help of parallel computing.
Defining relations of this problem related to the quadratic programming
problem, that is solved by Vulf method. Parallel calculations are executed on the cluster which is the most available type of scalable parallel computer.
