Symmetric multiprocessing (SMP) is an architecture that enables two or more processing units to share the same memory. It has been around since the 1960s and is now supported by all popular operating systems. In early SMP systems, several single-core CPUs were employed, which eventually evolved into the multi-core chips that we use in modern servers and smartphones.
The Advantages of Symmetric Multiprocessing
Symmetric multiprocessing provides several benefits, including:
- Improved performance: By distributing processing tasks among different CPUs, SMP systems can handle more workloads simultaneously, resulting in faster processing times and improved overall performance.
- Redundancy: SMP systems typically incorporate fault tolerance features that enable them to continue operating even if one or more processors fail.
- Scalability: SMP systems can be scaled up by adding more processors to the system, making it easier to accommodate growing workloads as business needs change.
Frequently Asked Questions (FAQ)
