The history of development of the SSCC computer resources and the organization of solving large-scale modeling problems are considered. The results of the project for the development of a multicomputer system SIBIR in the 80-s, the current SSCC structure, the main results of its operation in 2004, and prospects for...

The architecture of an innovative portal based on a fine-grain modularity and an assembly technology is presented. The portal resources and services for the interaction between participants of the innovative activity within a common information space are realized. The investigation of the system and the creation of its prototype have...

The basic means and methods to increase the efficiency of the sequential numerical simulation programs are considered. The main components of the modern hardware and software which affect the programs efficiency are discussed. The most important guidelines and advices for application programmers are outlined.

With evolution of mathematical modeling and creation of high-performance computer systems, many scientific applications have appeared, demanding an increase in computational performance higher than any of available supercomputers can provide.

The new parallel algorithm has been developed and implemented for solving the axially symmetric problem of the interaction of a plane shock wave with a free bubble system (cluster) resulting in the formation of a stationary oscillating shock wave. The important characteristics of the problem in question, such as acceleration...

This paper considers aspects of parallelizing of the solution process of problems of the integer linear and quadratic programming as well as of problems of global optimization of the non-convex quadratic programming.

The experimental library PLVIP for parallel image processing, elaborated and implemented in the Image Processing Laboratory of the ICM&MG SB RAS is described. The library is built on the vertical processing principle and is installed on the multiprocessor computers of the Siberian Supercomputer Center, MVS-1000/M and RM600-E30. The basic characteristics...

By now a substantial body of literature has evolved which deals with the numerical simulation of the 3D convective currents in the Earth’s mantle (see, e.g., [1–4] and references therein). A crucial point is to estimate the reliability of numerical experimental results because the similarity principle fails when the dynamical...

With MVS-1000M the distribution of particle and gas density in the soliton were investigated, as well as their velocities, angular momentum, flow of gas and particles through soliton and vorticity of particle velocity. It is shown that in the soliton the high values of gas and dust densities and gas...
