Role of parallel and distributed computing in beam physics

In this paper the role of distributed and parallel computing in beam physics is discussed. The natural parallel and distributed structures of beam physics problems allow the use of parallel and distributed computer systems. But the usual approaches based on traditional numerical methods demand using the resources of supercomputers. This leads to the impossibility of using such multiprocessing systems as computational clusters. In this paper some examples of beam physics problems are discussed from the computational point of view using clustered systems.
