Actor-Based Scalable Simulation of N-Body Problem.

Efficient solutions of the N-body problem make it possible to conduct large-scale physical research on the rules governing our universe. Vast amount of communication needed in order to make each body acquainted with the information on position of other bodies renders the accurate solutions very quickly inefficient and unreasonable. Many approximate approaches have been proposed, and the one introduced in this paper relies on actor-based concurrency, making the whole design and implementation significantly easier than using, e.g. MPI. In addition to presenting three methods, we provide the reader with tangible preliminary results that pave the way for future development of the constructed simulation system.
