Swiss Supercomputer 'Piz Daint'

Under National Super Computing Mission (NSM), India is fast expanding its supercomputer facilities and developing the capacity to manufacture its own supercomputers in the country.

Infrastructure planned in NSM Phase-I has already been installed and much of Phase-II is already in place, said a release by Ministry of Science & Technology. The ministry said -

the network of supercomputers through the country will soon reach to around 16 Petaflops (PF). Phase-III, to be initiated in January 2021, will take the computing speed to around 45 Petaflops.


Soon the work on Phase-III will start in 2021 and will include three systems of 3 PF each and one system of 20 PF as a national facility.

Besides, with recent announcement of a 100 Artificial Intelligence (AI) PetaFlops supercomputing system, PARAM Siddhi – AI, which is being created and installed in C-DAC by NVIDIA, India is fast expanding its supercomputer facilities and developing the capacity to manufacture its own supercomputers in the country. Yet, comparing to other developed countries India has to still come a long way.

For an instance -- currently the total network of supercomputers across India, which is yet to reach 16 Petaflops (PF), is less than of Piz Daint, a supercomputer in the Swiss National Supercomputing Centre, which has performance power of 27.1 Petaflops (PF) [theoretical peak performance] and ranked 10th in TOP500 ranking of supercomputers until June 2020.

Pratyush and Mihir, the two supercomputers of India, ranked in at 67th and 120th spot on the list of TOP500.

The most powerful Supercomputer across the globe is Japan's Fugaku, which has a High Performance Linpack (HPL) result of 415.5 Petaflops (PF). Number.2 on the list is Summit, an IBM-built supercomputer that delivers 148.8 Petaflops on HPL.

India's NSM mission was targeting to establish a network of supercomputers ranging from a few teraFlops (TF) to Hundreds of teraFlops (TF) and three systems with greater than or equal to 3 petaFlops (PF) in academic and research institutions of National importance across the country by 2022. It is to be noted that One petaFLOPS is equal 1,000 teraFLOPS.

India's Indigenous Supercomputing Work under NSM 

So FarUnder the NSM, more than 2400 supercomputing manpower and faculties have been trained, till date.




The first supercomputer assembled indigenously -- 'Param Shivay' -- was installed in IIT (BHU), followed by Param Shakti and Param Brahma at IIT-Kharagpur and IISER, Pune, respectively.

India has developed an Indigenous server (Rudra), which can meet the High-Performance Computing (HPC) requirements of all governments and PSUs. This is the first time that a server system was made in India, along with the full software stack developed by C-DAC.

In addition to these, this system can handle incredibly large-scale AI workloads increasing the speed of computing-related to AI several times.
