Understanding the National Supercomputing Mission
The National Supercomputing Mission (NSM) represents a cornerstone of India's push towards technological self-reliance in high-performance computing (HPC). Launched in 2015 as a flagship initiative by the Government of India, NSM is a collaborative effort between the Ministry of Electronics and Information Technology (MeitY) and the Department of Science and Technology (DST). Its primary goal is to build a robust ecosystem for supercomputing that empowers researchers, scientists, and industries with cutting-edge computational power.
High-performance computing refers to the use of aggregated computing power from multiple processors and servers to solve complex problems that traditional computers cannot handle efficiently. Supercomputers under NSM, measured in petaflops—a petaflop equals one quadrillion (10^15) floating-point operations per second—enable simulations in fields like weather forecasting, drug discovery, aerospace design, and climate modeling. By fostering indigenous development, NSM reduces India's dependence on foreign technology, aligning with the Atmanirbhar Bharat (Self-Reliant India) vision.
Over the past decade, NSM has evolved from conceptual planning to deploying dozens of supercomputers across the country. Institutions like the Indian Institute of Science (IISc) in Bengaluru and the Centre for Development of Advanced Computing (C-DAC) have been pivotal in execution. This mission not only boosts research but also creates opportunities in academia and industry, particularly for those pursuing careers in computational sciences.
🚀 Historical Evolution and Objectives
India's supercomputing journey began in the 1990s with C-DAC's PARAM series, but NSM marked a structured national effort. Approved with a budget of over Rs 4,500 crore (approximately $730 million) for seven years, the mission was extended until December 2025 to complete ongoing phases. Its objectives include deploying over 70 indigenous supercomputers, developing core components like processors and interconnects domestically, and establishing a nationwide HPC grid connected via high-speed networks.
The mission emphasizes three pillars: hardware development, software stacks, and application-driven research. For instance, C-DAC's PARAM Rudra servers and Trinetra interconnects exemplify 100% indigenous hardware. Software like open-source AlmaLinux ensures sovereignty and cost-effectiveness. These elements address national priorities such as disaster management, genomics, and artificial intelligence (AI).
- Enhance R&D capabilities in academia and industry.
- Train over 10,000 researchers, including PhD scholars, in HPC usage.
- Bridge the digital divide by making supercomputing accessible beyond metros.
By 2025, NSM had already supported more than 10,000 users, demonstrating its transformative impact on scientific discovery.
Phases of Implementation and Key Milestones
NSM unfolded in three phases, each building computational capacity progressively. Phase I (2015-2018) focused on utilizing existing foreign systems while kickstarting indigenous designs, deploying initial PARAM systems at IISc and IITs with a combined capacity of around 17 petaflops.
Phase II (2019-2022) accelerated indigenization, adding systems like PARAM Siddhi-AI at C-DAC Pune, ranked among the world's top 100 supercomputers at 5.2 petaflops. By March 2025, 34 supercomputers were operational, aggregating 35 petaflops, with 10 more under construction—totaling 37 systems.
Phase III, extended into 2025-2026, prioritizes exascale computing (10^18 flops) ambitions. Notable milestones include:
- 2017: Deployment of PARAM Shivay at IIT BHU, India's first 100% made-in-India supercomputer.
- 2020: PARAM Siddhi-AI excels in COVID-19 drug modeling.
- 2023: Nine additional systems announced under Digital India extensions.
- 2025: IISc's PARAM Pravega at 3.3 petaflops becomes top academic supercomputer.
These achievements have positioned India with the third-largest HPC infrastructure in the Indo-Pacific region. 
For researchers eyeing research jobs in HPC, these milestones open doors to collaborative projects at premier institutions.

📈 Latest Developments in 2026
Entering 2026, NSM hit new highs with the inauguration of PARAM SHAKTI at IIT Madras and PARAM Rudra facilities at IIT Madras and IIT Bombay. On January 8, 2026, MeitY Secretary S. Krishnan launched the 3.1 petaflop PARAM SHAKTI, India's first fully indigenous next-generation supercomputer. Powered by PARAM Rudra servers, Trinetra interconnects, and AlmaLinux OS, it boasts over 80% utilization within days, with a power usage effectiveness (PUE) of 1.2-1.4 for energy efficiency.
Similarly, IIT Bombay's PARAM Rudra enhances aerospace and climate research. These systems, part of NSM's final push, enable breakthroughs in drug discovery, fluid dynamics, and AI-driven simulations. Posts on X highlight national pride, with users celebrating the shift from assembly to full design in India.
MeitY reports emphasize applications in flood forecasting and genomics, underscoring real-world impact. This surge aligns with India's exaflop ambitions, planned via C-DAC within five years. For academics, these facilities mean faster grant approvals and interdisciplinary collaborations. Explore postdoc opportunities leveraging such infrastructure.
| Supercomputer | Location | Capacity (Petaflops) | Key Features |
|---|---|---|---|
| PARAM SHAKTI | IIT Madras | 3.1 | 100% Indigenous, AI-Optimized |
| PARAM Rudra | IIT Bombay/Madras | 3+ each | Rudra Servers, Energy-Efficient |
| PARAM Siddhi-AI | C-DAC Pune | 5.2 | Global Top 100 |
Indigenous Technology Stack: A Game-Changer
NSM's hallmark is its focus on atmanirbharta. Unlike earlier reliance on imported chips, systems now use C-DAC's Rudra multi-core Arm-based processors, capable of 2.5 petaflops per rack. The Trinetra high-speed interconnect rivals global standards, ensuring low-latency data transfer essential for large-scale simulations.
Software sovereignty comes via ENGAGE portal, a user-friendly interface for job submission, aggregating all NSM resources. This stack supports diverse workloads, from molecular dynamics to seismic analysis. Energy efficiency is prioritized, vital for India's power constraints, with liquid cooling reducing operational costs by 30%.
Such innovations inspire academic CV enhancements for HPC specialists, highlighting contributions to national missions.
