Top Supercomputers In India

A supercomputer is a class of highly powerful computers used for scientific purposes and engineering tasks requiring extremely high computing capabilities. They are also used to monitor climate and are heavily utilized in the space science industry. Unlike conventional computers, supercomputers have multiple CPUs to execute logic operations effectively. The government of India launched its National supercomputing Mission in the year 2015 with the aim of providing seventy-four institutions with high-performance computing facilities by 2022. It is a seven-year-long mission and has been divided into three phases. This initiative of the government has skyrocketed the urge to develop new supercomputers in India. Here we bring our list of the top supercomputers built in India.

Pratyush and Mihir are used together to perform weather forecasting tasks. These two supercomputers, when clubbed together, can achieve a peak performance that is comparable to PARAM Siddhi-AI. 


SAHASRAT is a Cray X-C40 Indian supercomputer developed by the Indian Institute of Science (IISc) Bengaluru. It is the latest addition to the Supercomputer Education and Research Center’s (SERC) high-performance computing systems. The supercomputer is powered by an Intel Haswell 2.5 GHz CPU cluster with twelve cores, NVIDIA G40 4K graphic accelerator, 128 GB of RAM, 2.1 PB storage, and 1376 nodes. It had also secured the 96th position on the list of top 500 supercomputers in the world in the past, making it one of the fastest supercomputers in India. 

SAHASRAT is mainly used for aeronautical engineering and molecular research. It has also been utilized for accurately mapping weather conditions of several areas through simulations.  


AADITYA is an IBM iDataplex supercomputer deployed at the Indian Institute of Tropical Meteorology (IITM) Pune. The supercomputer features Intel Sandy Bridge processors with 2384 compute nodes, 149 TB RAM, NVIDIA GF100GL graphic card, and 6 PB of storage space. Each node of AADITYA’s processor has 32 cores. The machine uses IBM’s General Parallel File system to manage its processing. AADITYA had earlier ranked 116th in the top 500 supercomputers list. IITM uses this Indian supercomputer to predict rainfall in smaller areas. It is also used to conduct meteorological research in the institute. 

6. Color Blossom

Color Blossom is a Cray-X30 supercomputer developed by the Tata Institute of Fundamental Research (TIFR) located in Hyderabad. This supercomputer of India runs on Linux operating system and is powered by an Intel Xeon 5E-2680 processor, NVIDIA Tesla K20x graphic card, 1.1 PB of storage, and has a maximum computing speed of 558.7 TFlops. TIFR is using Color Blossom under the Indian Lattice Gauge Initiative to conduct research on quantum chromodynamics and physics. 


The Center for Development of Advanced Computing, along with Intel and Netweb Technologies, built PARAM YUVA-II as the successor of the previous generation YUVA in February 2013. It secured 69th position in the list of top 500 supercomputers in the world in the same year. YUVA-II is one of the fastest high-performance computing systems in the PARAM series of supercomputers. 

Gree500 list of 2013 listed YUVA-II in 44th position globally among the most power-efficient supercomputers with a performance of 1,760.20 megaflops. It is powered by Intel Xeon 5E-2670 and has a storage capacity of 200 TB. The supercomputer can be used in various sectors like pharmaceutical research, weather forecasting, aerospace engineering, and bioinformatics.
