Monitietokonejärjestelmien

Monitietokonejärjestelmien, often translated as multiprocessing systems, refers to a computer architecture where two or more processors share a common memory and communication path. This allows for the simultaneous execution of multiple tasks or programs by different processors, significantly increasing computational power and efficiency compared to single-processor systems.

The primary goal of multiprocessing is to improve performance by dividing workloads. This can be achieved through various approaches, such as tightly coupled systems where processors are closely connected and share resources extensively, or loosely coupled systems where processors are more independent. Within a multiprocessing system, tasks can be executed in parallel, meaning different parts of the same program run on different processors simultaneously, or concurrently, where multiple independent programs run on different processors at the same time.

Multiprocessing systems are crucial for handling demanding applications like scientific simulations, complex data analysis, real-time control systems, and high-traffic web servers. They enable faster completion of complex computations, improved responsiveness for interactive applications, and greater overall system throughput. The management and scheduling of tasks across multiple processors are handled by the operating system, which plays a vital role in optimizing resource utilization and preventing conflicts between processors. Despite their advantages, multiprocessing systems also present challenges in terms of software development, synchronization between processors, and managing shared resources to avoid issues like race conditions.
