AIRRAWAT SUPERCOMPUTER
Did you notice my blog name "AIRAWAT" It is an Indian supercomputer Let's discuss about supercomputer
WHAT IS SUPER COMPUTER?
A supercomputer is a high-performance computing system that ranks among the fastest computers globally. Supercomputers are designed.
simply a fast computer with a large number of CPUs. An ordinary computer uses serial processing. But the super computer works in an entirely different way, typically using parallel processing instead of the serial processing. i.e., instead of doing one thing at a time, it does many things at a time. AADITYA super computer used by Indian Institute of Tropical Meteorology is currently considered as India's fastest supercomputer. AADITYA is 790 + Tera Flops High Performance Computing System formed using IBM iDataPlex cluster.
