In operating systems, a multiprocessor system<\/strong> refers to a computer system with multiple processors (CPUs) that work collaboratively to execute tasks. These systems can be categorized based on how they share memory and resources:<\/p>\n Symmetric Multiprocessing (SMP):<\/strong> All processors share a single, unified memory space and have equal access to I\/O devices. This architecture allows any processor to execute any task, promoting load balancing and fault tolerance.<\/p>\n<\/li>\n Asymmetric Multiprocessing (AMP):<\/strong> Each processor is assigned specific tasks, and there’s typically a master-slave relationship among processors. One processor controls the system, while others perform assigned tasks.<\/p>\n<\/li>\n<\/ol>\n Key Concepts in Multiprocessor Systems:<\/strong><\/p>\n Parallelism:<\/strong> Multiple processors can execute different parts of a program simultaneously, reducing execution time.<\/p>\n<\/li>\n Scalability:<\/strong> The ability to add more processors to improve performance without significant changes to the system’s architecture.<\/p>\n<\/li>\n Synchronization:<\/strong> Coordinating processors to ensure they don’t interfere with each other, especially when accessing shared resources.<\/p>\n<\/li>\n Cache Coherence:<\/strong> Maintaining consistency of data stored in local caches of each processor.<\/p>\n<\/li>\n<\/ul>\n Understanding these concepts is crucial for the GATE Computer Science exam, as questions related to multiprocessor systems often appear under topics like operating systems and computer architecture. For a comprehensive study, refer to standard textbooks and resources that cover these topics in depth.<\/p>\n Here\u2019s a simplified and clear explanation of the Concept of n<\/em>-Processor System<\/strong> from Operating Systems<\/strong> \u2013 helpful for GATE Computer Science (Day 01, Part 19)<\/strong> level preparation.<\/p>\n An n-processor system<\/strong> refers to a computer system that has n CPUs (processors)<\/strong> working together<\/strong> to execute processes in parallel or concurrently<\/strong>. This setup improves performance<\/strong>, throughput<\/strong>, and efficiency<\/strong>.<\/p>\n\n
