Paralelliprosessointi

Paralelliprosessointi, often translated as parallel processing, is a type of computation in which many calculations or processes are carried out simultaneously. Large problems can often be divided into smaller ones, which can then be solved concurrently. This approach speeds up computation by executing multiple instructions at the same time.

In traditional sequential processing, a single processor executes instructions one after another. In contrast, parallel processing utilizes multiple processors or processing cores to work on different parts of a task or on entirely separate tasks at the same time. This can be achieved through various architectures, including shared-memory systems where all processors have access to the same memory, and distributed-memory systems where each processor has its own private memory.

The benefits of parallel processing are significant, especially for computationally intensive applications such as scientific simulations, weather forecasting, complex data analysis, and artificial intelligence. By distributing the workload, parallel processing can drastically reduce the time required to complete these tasks, enabling researchers and developers to tackle more complex problems and achieve faster results. However, designing and implementing parallel programs can be more complex than sequential programming, requiring careful consideration of how to divide tasks, manage communication between processors, and synchronize operations.
