摘要:In various spheres of activities, we often face the necessity to find the best or fastest way of solving a relevant problem. Nowadays, computer technologies are applied in solving most problems: in great flow of information processing as well as in scientific research. Complex problems, solution of which is problematic by using only one computer, are solved by several computers connected into a network. Seeking effective usage of computer network for parallel calculations conceptually different software can be applied. In the article, the analysis of clusters by classical parallel solution algorithms is presented. An approximate value of π, matrix and vector and a system of linear equations and matrices product algorithms are analyzed. The present study consider a cluster that consists of 60 processors, as well as problem solution of cluster operating in the system with Windows XP at different speeds of networks.
