Supercomputer


    Supercomputers are mighty computers that are capable of performing highly complex calculations at extremely high speeds. The speed of supercomputers is now measured in Flops (floating-point operations per second). These machines are designed for use in scientific research, engineering, weather forecasting, and other applications that require substantial computing power. Universally, Seymour Cray is known as the father of the supercomputer.

Who is the Father of the Supercomputer? 🖥⚡

When we talk about supercomputers — those insanely powerful machines capable of performing trillions of calculations per second — one name stands tall: Seymour Cray.

Born in 1925, Seymour Cray was an American electrical engineer whose vision and designs shaped the entire supercomputing industry. Often called "the father of the supercomputer", he founded Cray Research in 1972 and went on to build groundbreaking machines like the Cray-1 in 1976. This wasn’t just fast for its time — it was revolutionary, setting new records in speed and efficiency.

Cray’s genius lay not just in raw processing power, but in innovative architecture and cooling techniques that made his machines practical for real-world science, weather prediction, nuclear research, and more. Even today, decades after his passing in 1996, modern supercomputers continue to draw inspiration from his design principles.

So, next time you hear about AI models, climate simulations, or space explorations running on massive computing power — remember the man who started it all.

💡 Seymour Cray — the mind that made “super” possible in supercomputers.

    A supercomputer typically has multiple processors working in parallel, as well as specialized hardware for performing specific types of calculations. They also have large amounts of memory and storage capacity, often measured in petabytes.

Some examples of the Fastest Supercomputers in the world:

1. Frontier: In the fastest supercomputer world, the Hewlett Packard Enterprise Frontier or OLCF-5 is the world's first and fastest exascale supercomputer, located at the Oak Ridge Leadership Computing Facility (OLCF) in Tennessee, United States. It is based on the Cray EX and was first operational in 2022. it is the successor to Summit (OLCF-4). As of March 2023, Frontier is the world's fastest supercomputer.

    It has the capability to achieve a speed of 1.102 exaFLOPS (Rmax), which is 1.102 Quintillion Operations per second. It uses an AMD CPU and GPU. The Operating System used in Frontier is Linux (HPE Cray OS-SUSE)


2. Fugaku: Fugaku is currently the most powerful supercomputer in Asia and the second-fastest supercomputer in the world. It is located in Japan. It has a peak performance of 442 petaflops.

4. Tianhe-2: Tianhe-2 was the fastest supercomputer in the world until it was surpassed by Summit. It is located in China and has a peak performance of 54.9 petaflops.

    Supercomputers are used in a wide range of scientific and engineering applications, including weather modeling, nuclear simulations, and drug discovery. They are also used in industry for tasks such as oil exploration, financial modeling, and product design.

Supercomputer in India: 

    There are several notable supercomputers developed in India over the years of development. Some of them are listed here:-

 

1. PARAM Super Computer: PARAM stands for "Parallel Machine". It is a series of supercomputers developed in India by the Centre for Development of Advanced Computing (C-DAC) in Pune, India. The first supercomputer, PARAM 8000, which can deliver speed in a GigaFlop, was launched in 1991, and since then, several models have been developed. PARAM Siddhi-AI, launched in 2020 with NVIDIA DGX superpod-based networking architecture, HPC-AI engine software frameworks, and a cloud platform from C-DAC, can deliver speeds up to 4.6 to 5.267 PetaFlops. In the development of supercomputers in India, there is a great contribution from Mr. Vijay Pandurang Bhatkar, also known as the father of Indian Supercomputers. He is an Indian Computer Scientist, IT Leader, and Educationalist. He is best known as the architect of India's national initiatives in Supercomputing, where he led the development of the PARAM supercomputers. he was the founder and executive director of C-DAC and is currently working on developing exascale supercomputing.

2. Annapurna: Annapurna is a supercomputer developed by the Indian Space Research Organization (ISRO) in Bangalore, India. It is used for space-related research and applications.

3. SAGA-220: SAGA-220 is a supercomputer developed by the Supercomputer Education and Research Centre (SERC) at the Indian Institute of Science in Bangalore, India. It is used for scientific research in various fields, including astrophysics, chemistry, and computational fluid dynamics.

4. Pratyush and Mihir Supercomputers: Pratyush is a series of supercomputers established at the Indian Institute of Tropical Meteorology (IITM) in Pune, India. Mihir is established at the National Centre for Medium-Range Weather Forecasting (NCMRWF) in Noida, India. It is used for weather forecasting and climate research.

    Pratyush and Mihir are two high-performance computing units (HPC). Pratyush is being 4.0 PetaFlops, and Mihir is being 2.8 PetaFlops. They provide a combined output of 6.8 PetaFlops computing speed.

    These supercomputers have contributed significantly to India's weather forecasting, climate research, scientific research, and development in various fields, including astrophysics, chemistry, and space technology.
