Large scale scientific and engineering applications in real life have given impetus to the development of high performance computing platforms via parallel processing. Over the last two decades or so, this has been demonstrated in the form of solutions being provided to complex situations like Weather Forecasting, Seismic Data Processing, Oil Exploration, Fluid Mechanics/Heat Transfer Simulations, Structural Mechanics, Materials and Molecular Design. One of the prime objectives of the Scientific and Engineering Computing Group (SECG) at C-DAC is to carryout Research and Development in multi-disciplinary applications. It also addresses the optimization and fine-tuning of the codes on PARAM series of machines. The activities of SECG are classified in the following broad categories:

	Computational Atmospheric Sciences
	Computer Aided Engineering
	Seismic Data Processing
	Bioinformatics
	Basic Sciences
	Evolutionary Computing

An important aspect of this group's activities is the collaborations with academic, research and industrial organizations in India as well as abroad. In the process of such interactions, a number of algorithms and computing techniques have been developed. Solutions of partial differential equations through finite element and finite difference methods, optimization through classical as well as evolution based techniques are few among them. Apart from such developments, a number of third party codes and softwares have also been ported on PARAM.

These on-going activities have proved that High Performance Computing is quite fruitful and mutually beneficial.
