Difference Between Symmetric and Asymmetric Multiprocessing

In this post, we will understand the difference between symmetric and asymmetric multiprocessing −

Asymmetric Multiprocessing

• In this kind of multiprocessing, the processors are not considered as equal.

• The task of the operating system is done by the master processor.

• There is no communication between the processors since they are controlled by the master processor only.

• In this multiprocessing, process follow the master-slave pattern.

• The systems are relatively inexpensive.

• This kind of multiprocessing systems are easier to design.

Symmetric Multiprocessing

• In this kind of multiprocessing, all the processors are considered equal.

• The tasks of the operating system are done by individual processors.

• All the processors communicate with each other since they use a shared memory.

• In this processing technique, the process is taken from the ‘ready’ queue.

• These kinds of multiprocessing systems are expensive.

• This kind of multiprocessing systems are complicated to design.
