Paralleeltöötlusvõime

Paralleeltöötlusvõime refers to the capability of a computer system to perform multiple computations or tasks simultaneously. This is achieved by dividing a problem into smaller parts that can be processed independently by different processing units, such as multiple cores within a CPU or separate processors in a cluster. The fundamental goal is to increase the speed and efficiency of computation by leveraging available resources concurrently.

Different approaches exist to achieve paralleltöötlusvõime. Task parallelism involves distributing different tasks across multiple processors, while data parallelism involves distributing the same task across multiple processors, each working on a different subset of the data. This distinction is crucial for optimizing performance based on the nature of the problem being solved.

The effectiveness of paralleltöötlusvõime is often measured by metrics like speedup, which quantifies how much faster a parallel computation is compared to its sequential counterpart. However, achieving perfect speedup can be challenging due to factors like communication overhead between processors, synchronization requirements, and the inherent sequential nature of some parts of a problem.

In modern computing, paralleltöötlusvõime is a cornerstone for handling complex tasks in fields like scientific simulations, artificial intelligence, data analysis, and high-performance computing. Its increasing importance reflects the growing demand for faster and more sophisticated computational solutions.
