Desktop Grid is a simple, yet efficient alternative to high-performance computing cluster for certain types of computational problems (mainly when there is no communication needed between computation nodes). Volunteer computing may help the researchers achieve high computational power in the cheapest way. The known drawback of such an approach to performing calculations is instability of...

For researches in the field of imitating modeling of telecommunication networks the project of [1] voluntary distributed computing NetMax@home was created. The project was created on the BOINC platform. At a stage of internal testing and at a project definition phase to public access some features of functioning of the project of the voluntary distributed computing without which efficiency of...

There is a fairly wide class of problems relating to discrete combinatorial optimization. Among them there are the problems of fundamental and applied orientation. The first one of them contains a number of problems on graphs, the problems of mathematical programming, operations research, etc. Many problems arise in the second direction of different fields of science (for example, trace...

Many problems from the areas of operations research and artificial intelligence can be defined as combinatorial optimization problems. Branch-and-bound method (B&B)is a universal and well known algorithmic technique for solving problems of that type.The root of the tree is the original problem, and the other nodes represent subproblems to be solved. Though algorithm considerably decreases the...

A lot of important combinatorial problems (from areas of formal verification, planning, cryptology, etc.) can be effectively reduced to Boolean satisfiability problem (SAT). Despite remarkable progress in theory practical solving of many real-life SAT instances remains unmanageable on traditional PCs. Volunteer computing project SAT@home was launched to solve such hard instances.
Analysis of...

In the last 10 years a significant progress in volunteer computing was achieved mainly due to the improvement of the open BOINC platform. There are volunteer computing projects based only on desktop PCs that have performance greater than 1 PFLOPs. Despite this fact there are some reasons why resources of computing clusters can be useful in volunteer computing. Firstly, a computing cluster is...

The voluntary distributed computing unite hundreds thousands people worldwide. There are thousands associations (teams) of volunteers. Hundreds scientific groups use voluntary computing capacities for receiving results in various areas of science. However, the questions connected with motivation of volunteers, the reasons of a choice of projects, withdrawal from voluntary calculations...
