What is multiprocessing

Simultaneously running of serveral processors (CPUs) is multiprocessing.

What is non-partition able multiprocessor.

In multiprocessing all SPUs share one real storage and channels.

The operating sytem manages the processing; it assigns work to the first available CPU; in case the CPU failed, work is routed to another CPU. A single OS copy running on many CPUs with one real storage is Non-partition able multiprocessor.

Advantage of multiprocessor systems provided the backup capabilites for CPU failures. Also, the overall instruction processing rate increased because many cpus are available to execute instructions.
