Which are the notable supercomputers in India?

The two most famous supercomputers developed in India are PARAM and Kabru. The former was the first Indian version of supercomputers to be introduced in 1991 in Pune. PARAM (Parallel Machine) 8000 was first developed by C-DAC (Centre for Development of Advanced Computing). It runs on Linux or IBM’s AIX Operating System, and is capable of making 100 billion calculations per second. India has sold two such machines to Russia and Singapore. The second supercomputer to be developed in India is Kabru; it is also the second-fastest in the country. It is named after Kabru, one of the tallest peaks in the Himalayan range.
