First of all, it is necessary to assess the high performance of the computer system that provides such processing, and secondly, to use special methods that will ensure real-time operation. In such a system, each processing and recognition method must be designed to ensure the operation of a single image transfer. In addition, PKI enables secrecy/confidentiality of communication and verification of data integrity.
For each job, the user declares his/her bid - the price (in the units of the nominal price) that he/she is ready to pay for a unit of the consumed CPU resource.

Persons who verify the authenticity of certificate applicants, users and website administrators on behalf of AliEn CA - Registration Authorities (RA). The public interface is where users, site administrators, and RAs request certificates from AliEn CA. The CA interface provides AliEn CA staff with the tools to issue certificates, revoke them, and issue CRLs.
Discussions with Predrag Buncic and Ara Grigoryan were very helpful in developing the AliEn CA architecture and working on the software issues.

The High Energy Physics community is the largest user of RDIG, as well as EGEE Grid infrastructure. Today, the new multidisciplinary field of application, nanotechnology and nanoindustry, is at the center of the RDIG consortium's attention. Therefore, if applied jobs were not initially developed for the particular runtime environment of the WNs, they cannot be processed directly in the grid.
The report presents current state and future trends of the JINR network, computing and information infrastructure.

POSTER REPORT THE IMMEDIATE PROBLEM OF SIMULATING THE ENTIRE SEISMIC WAVE FIELD IN A COMPLEXLY BUILT GEOMEDIUM Z. The problem of simulating the entire seismic wave field is one of the pressing problems of geophysics, especially seismic research. It is necessary to provide a three-dimensional computer simulation of the entire field of elastic deformations and deformations with an attributed origin in a heterogeneous elastic medium.
Calculation of the entire wave field in the geomedium based on the new method for solving the problems of seismoacoustics.

The main added value is that Grid enables full automation of the process of finding a set of suboptimal variants. Plasma turbulence is very challenging from a theoretical point of view due to the nonlinearity and high dimensionality of the governing equations. Functionally, the formative network system in the federation is set to be quite limited in the first phase.
We present results obtained at low temperatures, where the convergence of the QTM method is slower and sequential calculations become very time-consuming.

Most of the courses were entry-level courses that provide an introduction to Grid technologies and the EGEE project. Today, various programs and hardware are available for organizing parallel and distributed computing. Thus, to support the efficiency of parallel and distributed computing, the common user needs accessible methods and tools for organizing the data structure, software and hardware support, specification and analysis of the entire computing infrastructure.
The report presents a multilevel mass-theoretic model of a distributed heterogeneous computing environment and tools for its construction.

Each partition of the distributed image is the separate service with its own unique name in the hierarchy of image services. One of the synergistic effects of the proposed approach is shown in the easy, transparent realization of the capability of distributed imaging by agglomeration of some different overlapped panoramic images. In the process, communication services in a distributed storage system solve common problems on their own.
Smooth operation and little intervention from the user side made this work very efficient and comfortable.

The solution of the evaluation task in DCE is assigned to the dispatcher built on the basis of perceptron-type artificial neural networks, the so-called neuro-dispatcher. In DCE, solving the problem of resource management is reduced to solving the problem of estimating the amount of resources needed for the performance of each part of the problem, as well as to the problem of making plans for the initiation of specific tasks. Artificial neural networks are used to solve the problem of estimating the amount of resources needed to perform the problem of estimating the amount of resources provided by CN and to choose an optimal combination of CN.
To carry out the process of scheduling the distributed computations, a genetic algorithm (GA) is used.

IGS ASM contributes to the real-time monitoring of earthquakes and the development of regional monitoring capacities, the implementation of real-time seismic data processing and the exchange of data at the regional and international level. Cross-border data exchange and regional applications for data collection and processing, which are essential for good quality monitoring, are in fact very limited. Service infrastructure and specialists will be involved in MD-Grid JRU scientific research and production grid activities in defining requirements, providing input data and interpreting results at national, regional and international levels.

Adaptation of the most popular quantum chemical packages: GAMESS (socket and parallel [MPI] variants), Gaussian, CPMD, Dalton-2 for work in distributed environments is provided. When defining and solving optimization problems for the grid system for the solution of the complex problem that presupposes parallelization, a concept of a processor configuration of the grid system consisting of branches is introduced. Thus, the optimal processor configuration of the grid system ensures minimum computation time for the most intensive branch when solving a complex problem.
Of course, the equalities in (2) can be achieved by increasing the number of network system processors.

The implementation of distributed calculations using Grid technologies is extremely promising for first-class problems. The proposed method implements the new paradigm "Integrated Computing Model" MIC, which is commonly used in real-time programming [1]. Currently, the well-known problem (see [1-2]) about the auxiliary external calculator in the theory of information security is becoming relevant from the point of view of the secure use of the Grid system.
At the same time, it should be taken into account that such problems are associated with the following limitation (a commercial or military secret): The user does not want to transfer all the input data of the investigated problems to the Grid system.

However, the general use accessible by globally distributed computer intelligence programmers is impossible. A mathematically closed correction is performed by computing tree-like structures implemented in the PARSEQ language and programming system. In the new axiomatics, the prospects of general accessible problem solving on a large group of connected computers will open for every programmer.
Logical expansion of the computer space on an unlimited number of connected computers requires attention to the problem of organizing reliable computations in an initially unreliable computing environment.
