  1. What Is Supercomputing? | IBM
    Supercomputers are measured in floating-point operations per second (FLOPS), with the fastest systems exceeding 1 exaFLOP, or 1 quintillion FLOPS.

    Understanding Supercomputer Speed

    1. Measurement Units: Supercomputer processing speed is typically measured in FLOPS, where one FLOP represents a single floating-point operation. Common benchmarks include:
    1. Current Leaders: As of 2025, the fastest supercomputers include:
    1. Applications: Supercomputers are utilized in various fields such as climate modeling, drug discovery, and complex simulations. Their immense processing power allows them to handle vast datasets and perform calculations that would be infeasible for standard computers.
    2. Technological Advancements: The evolution of supercomputers has led to systems that can perform calculations millions of times faster than typical personal computers. For instance, while a high-end laptop might achieve several hundred GigaFLOPS, supercomputers can reach speeds in the ExaFLOPS range.

      In summary, supercomputers represent the pinnacle of computational power, with processing speeds that enable groundbreaking research and technological advancements across various scientific disciplines.
