Power supply and industrial growth are closely related, along with the development of industrial sectors and the diversification of power consumption structure. Effective and rational grasp of current power demand structure is conducive to stable power supply. In this paper, we build the evaluation index system of industrial power consumption structure in allusion to the structural characteristics of it in Jilin Province and combined with the actual situation, then proposed the structure evaluation model of industrial power consumption based on PSO (Particle Swarm Optimization) and support vector machine algorithms. In addition, we collect the industrial power consumption data in recent 60 months of Jilin Province to do empirical analysis, and testify that the method has high accuracy. The results show that the model works well, and the method are practical and feasible.

The demand for computing power in computational electromagnetics (CEM) is continuously increasing. Meanwhile, cooperative engineering is becoming more and more present in daily research and development workflows. Projects are often developed by teams, which interact remotely, and need tighter and tighter connectivity. Grid computing (GC), from the perspective of progress in computer networks, seems a promising way to satisfy both the need of high-performance computing platforms, and the requirements for effective cooperative computing. In this paper, researchers involved in CEM are introduced to grid computing, and to the use of grid computing for CEM. Two real applications are proposed, with a critical discussion on potential benefits and drawbacks with respect to alternative strategies.

Alternating Direction Implicit (ADI) methods have been in use since 1954 for the solution of both parabolic and elliptic partial differential equations. The convergence of these methods can be dramatically accelerated when good estimates of the eigenvalues of the operator are available, However, in the case of computation on parallel computers, the solution of tridiagonal systems imposes an unreasonable overhead. We discuss methods to lower the overhead imposed by the solution of the corresponding tridiagonal systems. The proposed method has the same convergence properties as a standard ADI method, but all of the solves run in approximately the same time as the "fast" direction. Hence, this acts like a "transpose-free" method while still maintaining the smoothing properties of ADI. Algorithms are derived and convergence theory is provided.

The rapid development of computer network has greatly popularized online education. Currently, most online education systems are using a learning platform of three-split screen courseware, in which stream media take up a majority of resources in bandwidth and storage space. Due to more and more students receiving online education, the load of stream media service is getting heavier, so that the traditional centralized architecture and image architecture cannot satisfy the access requirements of a large number of nationwide students. Therefore, a highly practicable stream media application architecture with quick response and high concurrency, reliability, stability, extendability. This paper first discusses the development of online education as well as the problem, then deeply explores the key technology to realize distributed architecture of stream media according to characteristics of online education, with the introduction of P2P and CDN architecture, along with stream media subdivision technology.

Soon after Java became popular for Internet applications, many other fields began looking at it. While Java's original thrust was client-side applets, today its dominant use is in large enterprise servers running business middleware. Its original client-side use is of secondary importance. Java for high-performance computing has been a popular issue and the subject of annual workshops over the last seven years, including the latest event, Java Grande ISCOPE, JGI'02, (http://***/javagrandeIscope/) held in Seattle from 3-5 November 2002. This meeting series joined forces with the internationalsymposium on computing in Object-Oriented Parallel Environments (ISCOPE), aimed primarily at object-oriented methods in science and engineering with an emphasis on the use of C++.

In this paper, we report on implementing an experimental distributedcomputing application for bioinformatics consisting of basic high-performance computing environments (Grid and PC Cluster systems), multiple interfaces at user portals that provide useful graphical interfaces to enable biologists who are not IT specialists to benefit directly from the use of high-performance technology.
