India’s journey in supercomputing is a remarkable story of technological ambition, indigenous innovation and sustained national investment. From the unveiling of PARAM 8000 in 1991, with a computing speed of one gigaflop, to an ecosystem that now boasts 40 supercomputers delivering a combined capacity of 68 petaflops, India has travelled a long distance. At the heart of this transformation is the National Supercomputing Mission (NSM), launched in 2015 under the leadership of Prime Minister Narendra Modi.
The evolution reflects a larger vision that Prime Minister Modi has consistently championed- an India that does not merely consume advanced technology but develops, manufactures and deploys it within the country. The National Supercomputing Mission with an outlay of about Rs 4,500 crore, represents this vision in action. Jointly steered by the Department of Science and Technology and the Ministry of Electronics and Information Technology, the mission seeks to build self-reliance in high-performance computing and establish a globally competitive supercomputing ecosystem.
The scale of progress is significant. As of September 2026, India has deployed 40 supercomputers with a combined capacity of 68 petaflops, including 13 high-end systems exceeding one petaflop. Another 12 systems have capacities between 500 teraflops and one petaflop, while 15 systems have capacities below 500 teraflops. The mission aims to establish 50 supercomputers with a cumulative capacity exceeding 123 petaflops across academic and research institutions.
This expansion is important not merely because of the numbers, but because of what supercomputing makes possible. High-performance computing is increasingly indispensable for artificial intelligence, weather forecasting, climate modelling, drug discovery, genomics, disaster management, space research and advanced engineering. India generates nearly 20 percent of the world’s data, making access to powerful computing infrastructure a strategic necessity.
The Modi government’s emphasis on indigenous capability is particularly noteworthy. Under the NSM, India has developed indigenous servers, system software, high-speed interconnect networks and cooling technologies. The Rudra series of servers, designed and developed by C-DAC, has emerged as a major milestone. By September 2026, 6,000 Rudra servers had been deployed in PARAM Rudra supercomputers, with another 1,500 under manufacturing.
This is precisely where Prime Minister Modi’s emphasis on Aatmanirbhar Bharat acquires technological depth. Self-reliance today is not confined to manufacturing everyday products, it extends to the most sophisticated layers of the digital economy. Developing critical computing infrastructure domestically strengthens India’s strategic autonomy and reduces dependence on imported technologies.
The societal applications of this infrastructure make the achievement even more meaningful. Supercomputing is being used for flood prediction, forest-fire modelling, urban pollution and weather forecasting, seismic imaging, genomics and drug discovery. A flood prediction system, for instance, can forecast floods in river basins up to two days in advance. Such capabilities can directly contribute to protecting lives, livelihoods and infrastructure.
The mission is also building India’s human capital. More than 16,000 researchers, including over 2,900 PhD scholars across more than 400 institutions, have benefited from NSM infrastructure. More than 1.5 crore compute jobs have been executed, contributing to over 1,990 research publications. Training programmes, hackathons, bootcamps, faculty development initiatives and dedicated learning platforms are helping create a wider pool of professionals skilled in high-performance computing, artificial intelligence and deep learning.
This combination of infrastructure, indigenous technology and skilled human resources reflects the broader development philosophy associated with Prime Minister Modi- create capabilities that generate capabilities. The objective is not simply to acquire machines, but to build an ecosystem in which Indian researchers, students, institutions, startups and industries can innovate at the frontier of technology.
The National Knowledge Network further strengthens this ecosystem by connecting supercomputing facilities across academic and research institutions through a high speed national network. It enables researchers to share computational resources, collaborate across geographical boundaries and accelerate scientific discovery.
The road ahead is equally ambitious. The integration of artificial intelligence with high-performance computing can transform areas ranging from agriculture and healthcare to energy, climate science and drug discovery. By bringing together government, academia, industry, startups and research institutions, India can turn advanced computing into practical solutions for national development.
Prime Minister Narendra Modi’s vision of a Viksit Bharat by 2047 rests on precisely such foundations like scientific capability, technological confidence, indigenous innovation and a skilled workforce. India’s rise from the one-gigaflop PARAM 8000 to a growing 68-petaflop supercomputing ecosystem is therefore more than a technological milestone. It is a powerful symbol of an India increasingly capable of designing its own future.
The supercomputing story demonstrates that when strategic vision is matched by sustained investment and indigenous innovation, technologies once considered the preserve of a few advanced nations can become instruments of national transformation. Under Prime Minister Modi’s leadership, India is steadily moving from being a technology user to becoming a technology creator- an essential transition on the journey towards a stronger, self-reliant and Viksit Bharat.
