What type of multiprocessing has each processor perform all tasks equally with no boss-worker relationship?

In symmetric multiprocessing (SMP), each processor in a multiprocessor system has equal access to the system resources, including memory, and operates under the same set of rules, meaning there is no assigned "boss" or "worker" relationship among the processors. This allows any processor to execute any task and handle any workload equally, promoting efficient load balancing and enhancing system performance.

This model contrasts with asymmetric multiprocessing, where one processor takes on a supervisory role while others carry out less complex tasks. In SMP, the processors work collaboratively and share the responsibilities, which can lead to improved reliability and fault tolerance since the workload can be distributed dynamically among the processors. The design of SMP systems allows for easier scaling as more processors can be added without significant restructuring of the system, making it a preferred architecture in systems requiring high availability and performance.
