Afanasy is a free and open source tool to control remote computing. You can compute something more quickly using render farm - remote computers connected by network. Afanasy designed for computer graphics (3d rendering and 2d compositing) parallel calculation. It can compute different frames (or even parts of frames) on several computers simultaneously.
