Unformatted text preview: oll processing, accounting, or record-keeping applications. To do so would waste an expensive and relatively rare resource. Supercomputers are often treated as a national resource. This is mainly because it is not economically viable to have many such facilities for developing countries because of the cost involved in setting up the facility, maintaining the facility, and fast obsolescence of technology. Another reason for this is that a nation's leadership role in energy, space exploration, medicine, industry, and other critical areas is unlikely to continue if its scientists must use computers that are less powerful than those available to their counterparts in other countries. For example, today's supercomputers are not fast enough to simulate airflow around an entire aircraft. Builders of new airplanes must therefore simulate the passage of air around separate pieces of the airplane and then combine the results to produce an effective aerodynamic design. It is believed that the first nation to build a fast enough supercomputer, which can simulate the airflow around a complete airplane, will be the country that develops planes with superior safety, reliability, and performance. The same holds good for other scientific research and development areas. Leaders in the development of supercomputers include Cray Research Company, IBM, Silicon Graphics, Fujitsu, and Intel. In India, we have a CRAY XMP-216 supercomputer installed at the National Center for Medium Range Weather Forecasting (NCMRWF) in Delhi, and an IBM SP/2 supercomputer installed at the Supercomputer Education and Research Center (SERC) in the Indian Institute of Science, Bangalore. Realizing the importance of supercomputers in the advancement of a nation, some national efforts of building supercomputers indigenously have also been initiated. This has resulted in the development of PARAM series of supercomputers by the Centre for Development of Advanced Computing (C-DAC), Anupam series of supercomputers by the Bhabha Atomic Research Centre (BARC), and PACE series of supercomputers by the Defence Research and Development Organization (...
