Wide area computer networks have become a basic part of today's computing infrastructure. Heterogeneous networks connect a variety of machines, including workstations, high-performance engines and even multiprocessors, present an enormous computing resource. Distributed computing today is widely used in scientific computations and information processing.
In the field of semiconductor and semiconductor device physics, electromagnetic wave propagation, plasma physics, and nuclear physics there is so-called ``weighted particle method''. This method is power tool for solution of very important and interesting problems. The main shortcoming of this method is a large expense of CPU time. Therefore, distributed computing is indispensable to a successful implementation of the method. From the computational point of view, it is a need to develop high-efficient algorithm for dynamic load balance and to provide fast information exchange between the nodes of network.
