Anupam is a series of supercomputers designed and developed by Bhabha Atomic Research Centre (BARC) for their internal usages. It is mainly used for molecular dynamical simulations, reactor physics, theoretical physics, computational chemistry, computational fluid dynamics, and finite element analysis. [1]
Bhabha Atomic Research Centre (BARC) carries out inter-disciplinary and multi-disciplinary R&D activities covering a wide range of disciplines in physical sciences, chemical sciences, biological sciences and engineering. Expertise at BARC covers the entire spectrum of science and technology. [4]
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 MIMD (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 MFlops. 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 TeraFLOPS on the standard High Performance Linpack (HPL) benchmark. The system is in production mode and released to users. [5]
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. [6]

A supercomputer is a computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). Since 2017, supercomputers have existed which can perform over 1017 FLOPS (a hundred quadrillion FLOPS, 100 petaFLOPS or 100 PFLOPS). For comparison, a desktop computer has performance in the range of hundreds of gigaFLOPS (1011) to tens of teraFLOPS (1013). Since November 2017, all of the world's fastest 500 supercomputers run on Linux-based operating systems. Additional research is being conducted in the United States, the European Union, Taiwan, Japan, and China to build faster, more powerful and technologically superior exascale supercomputers.
In computing, floating point operations per second is a measure of computer performance, useful in fields of scientific computations that require floating-point calculations. For such cases, it is a more accurate measure than measuring instructions per second.
PARAM is a series of Indian supercomputers designed and assembled by the Centre for Development of Advanced Computing (C-DAC) in Pune. PARAM means "supreme" in the Sanskrit language, whilst also creating an acronym for "PARAllel Machine". As of November 2022 the fastest machine in the series is the PARAM Siddhi AI which ranks 163rd in world, with an Rpeak of 5.267 petaflops.
Raja Ramanna was an Indian physicist who is best known for his role in India's nuclear program during its early stages.
The Bhabha Atomic Research Centre (BARC) is India's premier nuclear research facility, headquartered in Trombay, Mumbai, Maharashtra, India. It was founded by Homi Jehangir Bhabha as the Atomic Energy Establishment, Trombay (AEET) in January 1954 as a multidisciplinary research program essential for India's nuclear program. It operates under the Department of Atomic Energy (DAE), which is directly overseen by the Prime Minister of India.
