RICCR Activities | Other Activities

RESEARCH ACTIVITIES:

In March 2001 the Centre began practical scientific and organizational activities. Research activity of the Centre was lead in the fields authorized by the Centre Joint Committee.

At the end of March 2001 the delegation of Russian scientists visited C-DAC, Pune and during that visit four contracts on scientific developments were signed. The following themes, which correspond to themes of ILTP projects, were chosen for the Joint work under the four Contracts:

1. R & D in Computational Fluid Dynamics

This project aimed to develop applied software for the calculation of the characteristics of launch vehicles.

State of the art: finalized.

Main results:

• The method of 3-D block-structured grid generation about complete vehicle configurations like RLV developed.
• Efficient and accurate numerical algorithms for the solution of compressible Euler, Navier-Stokes and thin layer NS equations past RLV obtained.
• The concrete data are submitted as izolines of pressure, heat transfer, friction coefficient on all windward kpart and leeward surface RLV.
• The global pressure field characterized by strong shock systems and interactions, both between RLV components in the far field.
• The surface flow patterns reveal shock-induced separations on the far-body region.

The code is ported on PARAM 10000 at C-DAC, Pune and RICCR ICAD, Moscow. The prolongation or new contract in this field is suggested.

2. R & D in Atmospheric Sciences

The aim of this project is parallelization and optimization for PARAM 10000 Global Spectral Medium Range Forecast Models.

State of the art: finalized.

The codes are ported on PARAM 10000 in C-DAC, Pune and RICCR-ICAD, Moscow. New project in this field is suggested "Investigation of the processes of interaction of atmosphere and ocean and development of the circulation model of Indian Ocean.

3. R & D in Seismic Data Processing

The goal of this project is development and theoretical analysis on finite-difference schemes for solution of direct problem in seismic modeling.

State of the art: finalized

Proposal (perspectives):

• Theoretical understanding and solver development for direct seismic problem in 3D geometry
• Version for parallel computer
• Implementation of direct geophysical modeling for different fundamental and applied problems

Main results: A set of finite difference schemes was analyzed. The optimal approach was suggested. Some test calculations were performed.

The code was ported on PARAM 10000 at C-DAC and RICCR-ICAD.

4. R & D in Parallelizing Compilers

The aim of this project is development of parallelizing compiler for PARAM type machine.

State of the art: Finalized.

Some version of such compiler is developed and transferred to C-DAC (Bangalore). C-DAC people have been trained on PARAM - 10000 , Moscow

All named projects were carried out on Supercomputer PARAM 10000, manufactured by C-DAC, Pune, India installed at Computer Center RICCR-ICAD with the subsequent installation of software on PARAM 10000 at C-DAC, Pune.

Thus the work begun within the framework of scientific ILTP Projects between C-DAC and ICAD RAS has received the concrete applied continuation within the framework of contracts between C-DAC and RICCR, i.e. the first experience of linking the two components of a scientific product creation was received: scientific and managing-commercial.
