India’s Supercomputing Mission: Building Home‑Made High‑Performance Computers

The National Supercomputing Mission aims to install 50 supercomputers across research institutions, providing more than 123 petaflops of total computing power.

🔑

Key Points

7 points
1

Goal: Deploy 50 supercomputers with a combined capacity exceeding 123 petaflops.

2

Current status (Sept 2026): 40 supercomputers, 68 petaflops total, including 13 systems above 1 petaflop.

3

PARAM Rudra series comprises about 6,000 Indian‑made servers, with additional units in production.

4

Applications span climate modelling, flood prediction, forest‑fire spread, genomics, material science, and artificial intelligence research.

5

Indigenous development includes high‑speed interconnects of 100‑200 gigabits per second and locally designed cooling solutions.

6

The National Knowledge Network connects all supercomputing facilities, enabling resource sharing across institutions.

7

Education programmes such as the EduHPC Workshop, the SWAYAM online course, and the HPC Shiksha Portal have trained thousands of students and faculty.

📖

Summary

By September 2026, 40 supercomputers with a combined capacity of 68 petaflops were already operational, including high‑end and mid‑range systems.

India’s journey began with the PARAM 8000 in 1991 and has progressed to the PARAM Rudra series, which uses thousands of domestically produced servers and software.

These machines are used for advanced research such as weather forecasting, flood early‑warning, forest‑fire modelling, drug discovery, and space science.

The mission also focuses on developing indigenous components like high‑speed interconnects, cooling technology, and a complete software stack for high‑performance computing.

Training initiatives, hackathons, and online courses have enabled more than 16,000 researchers, including thousands of PhD students, to use these resources.
