Which of the following is not an appropriate set of super computers of India ?

Question

Accepted Answer

The correct option is (4):
This option, Alokik, Adwitiya, Param, Aayush, is the set that is **not** considered an appropriate collection of Indian supercomputers. While 'Param' is the foundational series name for India's indigenous supercomputers (such as PARAM Siddhi, PARAM Pravega, and PARAM Ganga), the specific names *Alokik*, *Adwitiya*, and *Aayush* are not officially recognized or documented names of major operational supercomputing systems in the country. The question specifically seeks the set that does not fit the category, and since this combination includes multiple unrecognized machine names, it is the inappropriate choice compared to the others which list actual systems.

The incorrect option is (1):
The set Padma, Yuva, Kanchanjanga, Shavaka is considered an appropriate collection because it contains multiple verifiable Indian supercomputers. *PARAM Padma* was India's first machine to be ranked on the world list, *PARAM Yuva* is a significant system from the PARAM series, and *PARAM Kanchenjunga* is a documented supercomputer installed at NIT Sikkim. The presence of three confirmed Indian supercomputers validates this set as appropriate.

The incorrect option is (2):
The set Sahasra, Aditya, Param Yuva-II, Shavaka includes prominent and well-known Indian HPC systems. *Aaditya* is a major HPC system used at the Indian Institute of Tropical Meteorology for weather and climate modeling. *PARAM Yuva-II* is a highly successful machine, which was the first Indian supercomputer to cross the 500 Teraflops mark. *Sahasra* is a known system, making this a strong set of actual Indian supercomputers.

The incorrect option is (3):
The set Padma, Sahasra, Ishan, Pratyush consists entirely of systems that are confirmed as Indian supercomputers or major HPC platforms. *PARAM Padma* is a key part of India's supercomputing history. *PARAM Ishan* is an established system installed at IIT Guwahati. *Pratyush* is currently one of the fastest supercomputers in India, primarily dedicated to meteorology and climate research. This set accurately represents a group of prominent supercomputers of India.
