PARALLEL AND DISTRIBUTED CALCULATIONS SUPPORTED AND MANAGED BY THE RELATIONAL DATABASE

A simple, based on a relational database, system, for a management of a parallel and a distributed computer calculations, is presented. In the proposed system, the parallel calculations are carried out according to a master/slave model. Because an input and an output data of programs are stored directly in the database, the use of files is reduced to a minimum. The management system allows for a combination of computing power of many computers for solving a single numerical problem
