India’s Rising Supercomputing Ecosystem, NSM & PARAM Rudra

India’s supercomputing ecosystem has grown from PARAM 8000 in 1991 to a nationwide High-Performance Computing (HPC) network under the National Supercomputing Mission (NSM).

As of September 2026, India has 40 supercomputers with a combined capacity of 68 petaflops (PF). These systems support research in Artificial Intelligence, weather forecasting, climate modelling, healthcare, drug discovery, disaster management, space science and big data analytics.

What is Supercomputing?

Supercomputing refers to the use of extremely powerful computers to solve complex problems and process huge amounts of data quickly.

Supercomputers use thousands of processors that can work on different parts of a problem at the same time. This is called parallel processing.

India’s Supercomputing Journey

India’s indigenous supercomputing journey began with PARAM 8000, developed by C-DAC and launched in 1991.

PARAM 8000 had a computing speed of about 1 gigaflop and laid the foundation for India’s PARAM series.

The series later included more advanced systems such as PARAM Yuva, which offered around 54 teraflops and supported applications such as weather forecasting and computational fluid dynamics.

This journey has now developed into a wider national ecosystem covering hardware, software, networking, applications and skilled manpower.

Role of National Knowledge Network in Supercomputing

The National Knowledge Network (NKN) acts as an important connectivity backbone for India’s supercomputing ecosystem.

It connects supercomputing facilities across academic and research institutions through a high-speed national network. This allows researchers to access computing resources, collaborate across institutions and share computational capabilities.

By connecting different research centres, NKN helps create a more integrated national High-Performance Computing ecosystem.

Why Is India’s Supercomputing Ecosystem Important?

India generates nearly 20% of the world’s data, creating a growing requirement for advanced computing infrastructure.

The expansion of supercomputing is important because it can:

• Accelerate scientific discoveries.
