India’s Rising Supercomputing Ecosystem

Key Highlights:

• The National Supercomputing Mission (NSM) was launched in 2015 with an outlay of ₹4,500 crore.
• As of September 2026, India has deployed 40 supercomputers with a combined capacity of 68 PetaFLOPS (PF).
• The mission aims to establish 50 supercomputers with a cumulative capacity exceeding 123 PF across various institutions.
• C-DAC and IISc implement the mission, which is jointly steered by the Department of Science and Technology (DST) and the Ministry of Electronics and Information Technology (MeitY).
• Indigenous developments include Rudra Series servers, PARAM Rudra supercomputers, and a complete HPC system software stack.

Detailed Insights:

• NSM aims to build self-reliance in supercomputing and strengthen India’s high-performance computing (HPC) capabilities for research and societal applications.
• HPC supports critical applications in computational biology, weather prediction, climate modeling, disaster management, and drug discovery.
• The mission aligns with the vision of Aatmanirbhar Bharat and contributes to Viksit Bharat 2047 by fostering indigenous technology and innovation.
• Key national applications include Genomics and Drug Discovery, Urban Environment Decision Support System, and Early Warning Systems for Flood Prediction.
• Indigenous components developed under NSM also include high-speed interconnect networks, cooling technology, and PARAM Shavak (a supercomputing-in-a-box for educational use).
• Skill development initiatives include workshops, hackathons, faculty training, the HPC Shiksha Portal, and the National Knowledge Network (NKN).
• NSM contributes to 11 UN Sustainable Development Goals (SDGs) by applying advanced computing to areas of national development.

Scientific/Technical Concepts Involved:

• Supercomputers: High-performance computing systems designed for complex calculations at exceptional speeds using multiple processors.
• Parallel Processing: A technique where multiple CPUs work simultaneously on different parts of a single computational problem.
• FLOPS (Floating Point Operations Per Second): A measure of a supercomputer's processing power, indicating calculations per second.
• PetaFLOPS (PF): A unit of computing speed equal to one quadrillion (10^15) floating-point operations per second.
