Introduction to Parallel Processing
Parallel processing is a technique that allows computers to execute multiple instructions or tasks concurrently, leveraging multiple processing units, such as cores or processors. This approach enables computers to tackle complex problems that would be impractical or impossible to solve using traditional sequential processing methods. By harnessing the power of parallel processing, researchers and developers can accelerate scientific discoveries, optimize business processes, and create innovative products.
Types of Parallel Processing Architectures
There are several parallel processing architectures, each with its strengths and weaknesses. Symmetric multiprocessing (SMP) architectures, for example, feature multiple processors sharing a common memory space, allowing for efficient communication and data exchange. Asymmetric multiprocessing (ASMP) architectures, on the other hand, use multiple processors with separate memory spaces, requiring more complex communication protocols. Distributed processing architectures, which comprise multiple computers or nodes connected via a network, offer a scalable and flexible solution for large-scale computations.
