Unformatted text preview: Parallel processing = one form of multiprocessing is a situation in which two or more processors operate in unison.Two benefits : increased reliablility and faster processing. Multi-core processors have several processors on a single chip. The first problem was the ability to spontaneously tunell at random “tunneling”. The second problem was that heat generated by the chip. Typical multiprocessing configurations - master /slave, loosely coupled, and symmetric Master/slave - asymmetric multiprocessing system single processor with additional slave processor . MASTER/ SLAVE – ADVANTAGE - IS ITS SIMPLICITY. MASTER/SLAVE - DISADVANATEES – • Reliability is no higher then for a single processor system because if the master processor fails the entire system fails. • I t can lead to poor use of resoursec because if a slave processor should become free while the master processor is busy the slave must wait until the master becomes free and can assign more work to it • I t increases the number of interrupts because all slave processors must...
