Parallel computing

Definition

Parallel computing is a type of computation where many calculations or processes are carried out simultaneously, leveraging multiple processors or computers. This approach enhances performance and efficiency, especially when dealing with large datasets or complex simulations, such as those found in the study of elastic and viscoelastic fluids. By breaking down tasks into smaller, manageable pieces that can be processed at the same time, parallel computing allows for faster problem-solving and analysis in fluid dynamics.
