Day 01Part 19- Operating System for gate%20 computer science – Concept of n processor System
In operating systems, a multiprocessor system 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:
-
Symmetric Multiprocessing (SMP): 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.
-
Asymmetric Multiprocessing (AMP): 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.
Key Concepts in Multiprocessor Systems:
-
Parallelism: Multiple processors can execute different parts of a program simultaneously, reducing execution time.
-
Scalability: The ability to add more processors to improve performance without significant changes to the system’s architecture.
-
Synchronization: Coordinating processors to ensure they don’t interfere with each other, especially when accessing shared resources.
-
Cache Coherence: Maintaining consistency of data stored in local caches of each processor.
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.
