daugiaprocesori

Daugiaprocesori refers to a computer system that utilizes multiple central processing units (CPUs). This architecture allows for parallel processing, where different tasks or parts of a single task can be executed simultaneously by different processors. The primary advantage of a multiprocessor system is increased performance and throughput, as it can handle more computational work in a given time compared to a single-processor system.

There are generally two main types of multiprocessor systems: tightly coupled and loosely coupled. In tightly coupled systems, processors share a common main memory and are often connected via a high-speed bus or interconnect. This allows for efficient communication and data sharing between processors. Loosely coupled systems, on the other hand, typically have their own local memory and communicate through message passing, often over a network. These are also known as distributed memory systems.

Multiprocessor systems are crucial for demanding applications such as scientific simulations, complex data analysis, high-performance computing (HPC), server environments handling numerous user requests, and modern operating systems that manage multiple concurrent processes. The efficiency of a multiprocessor system is highly dependent on the operating system's ability to effectively schedule tasks across the available processors and manage shared resources to avoid contention. Challenges in multiprocessor design include ensuring proper synchronization between processors, managing cache coherence, and optimizing inter-processor communication.
