Parallelism

Noun · Development

Definitions

  1. The simultaneous execution of multiple computations, typically on separate CPU cores or machines. Unlike concurrency (which is about structure), parallelism is about actual simultaneous execution. Critical for performance in data processing, scientific computing, and rendering.

    In plain English: Doing many things at the exact same time using multiple processors, like having 10 people each read one chapter of a book simultaneously instead of one person reading all 10.

    Example: "We split the dataset across 16 cores and the job went from 4 hours to 15 minutes — that is parallelism."
