Actual problems of beam physics computing

This report is devoted to discussion actual problems of current status in beam physics computing and some solution paths. All present, approaches can be divided into two different types: analytical (theoretical) and numerical simulation. The first type is based on theoretical investigations for some approximation models without use numerical simulation actively. The second, on the numerical simulation of some more complete models using computer systems including supercomputers and computational clusters. In the report, some realization paths of this formulated program are discussed. We hope that it gives effective and adequate instruments for further investigation in beam physics.
