Introduction

(BARC) carries out inter-disciplinary and multi-disciplinary R&D activities covering a wide range of disciplines in

physical sciences Physical science is a branch of natural science that studies non-living systems, in contrast to life science. It in turn has many branches, each referred to as a "physical science", together called the "physical sciences". Definition Phy ...

chemical sciences Chemistry is the scientific study of the properties and behavior of matter. It is a natural science that covers the elements that make up matter to the compounds made of atoms, molecules and ions: their composition, structure, properties, ...

biological sciences Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary ...

engineering Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more speciali ...

. Expertise at BARC covers the entire spectrum of science and technology. BARC has started development of supercomputers under the ANUPAM project in 1991 and till date, has developed more than 20 different computer systems. All ANUPAM systems have employed parallel processing as the underlying philosophy and

(Multiple Instruction Multiple Data) as the core architecture. BARC, being a multidisciplinary research organization, has a large pool of scientists and engineers, working in various aspects of nuclear science and technology and thus are involved in doing diverse nature of computations. To keep the gestation period short, the parallel computers were built with commercially available off-the-shelf components, with BARC's major contribution being in the areas of system integration, system engineering, system software development, application software development, fine tuning of the system and support to a diverse set of users. The series started with a small four-processor system in 1991 with a sustained performance of 34 M Flops. Keeping in mind the ever increasing demands from the users, new systems have been built regularly with increasing computational power. The latest in the series of supercomputers is the 4608 core ANUPAM-Adhya system developed in 2010-11, with a sustained performance of 47 Tera FLOPS on the standard High Performance Linpack (HPL) benchmark. The system is in production mode and released to users. In 2001, BARC achieved a new milestone in developing a supercomputer 20-25 times faster than the fastest computer built by other institutes in the country when it commissioned ANUPAM-PENTIUM.
