per second), which can range from teraflops (trillions of calculations per
second) to petaflops (quadrillions of calculations per second) and beyond.
Specialized Hardware: Supercomputers often employ
specialized hardware components, such as accelerators (e.g., GPUs or TPUs),
custom interconnects, and high-speed storage solutions. These components
enhance performance and efficiency for specific types of computations.
Large Memory Capacity: Supercomputers typically have an
extensive and fast memory hierarchy, including RAM and high-speed cache, to
accommodate the substantial data requirements of their applications.
Scalability: Supercomputers are designed to scale
efficiently, allowing additional processors or nodes to be added to the system
to handle increasingly complex tasks.
