Parallel Computing
Short Definition: Parallel computing is a type of computation in which many calculations or processes are carried out simultaneously.
What Is Parallel Computing?
Parallel computing refers to a computational approach that divides large problems into smaller, independent tasks that can be processed concurrently across multiple computing resources. This technique leverages the power of multiple processors or computers working together on a shared task to significantly reduce processing time. By breaking down complex computations into manageable pieces, each processor handles a portion of the task simultaneously, leading to more efficient problem-solving and faster results. Parallel computing is commonly used in scientific simulations, data analysis, and applications requiring significant computational power.
