Supercomputers: Giants of the Computing World

Supercomputers are advanced machines designed to solve incredibly complex, large-scale, and calculation-intensive problems that would take ordinary computers years to complete. They are essential for tasks such as weather forecasting, simulating nuclear reactions, and modeling the early universe.

Parallel Computing

• Core Concept: Instead of relying on a single processor, supercomputers use thousands or millions of processors working simultaneously, known as parallel computing.
• Process: Each processor (or core) addresses a small part of a problem. When combined, these solutions yield a complete answer faster than a single processor could.

India's Supercomputing Initiative

• Historical Context: India's supercomputing journey began in the late 1980s with the PARAM series.
• National Supercomputing Mission (NSM): Launched in 2015 to develop indigenous systems and expand high-performance computing across India.
• Current Leaders: AIRAWAT-PSAI at C-DAC in Pune is India's fastest, with other systems installed across academic and research institutions.
• Applications: Weather and climate modeling, molecular dynamics, nanotechnology, AI models, and more.
