What is the use of shared memory multiprocessor?

Shared memory multiprocessors use a common memory space accessible by multiple processors, allowing them to efficiently communicate and share data. This architecture facilitates faster inter-processor communication compared to message-passing systems, as processors can read and write to the shared memory directly. It is particularly beneficial for applications requiring high levels of parallelism and low-latency access to data, such as scientific computing and real-time processing. However, managing access to shared memory can introduce complexity, including the need for synchronization mechanisms to prevent data inconsistencies.
