compare uniprocessor systems with multiprocessor systems in the following aspect a) ease of programming b) the need for synchronization c) performance evaluation d) run time systems

for both multiprocessor and uniprocessor sytems, what is the ease of programing, the need for synchronization, performance evealuation and run time system   Also what is the trend in compuring based on the number of processing elements    Thanks

To effectively identify multiprocessor systems, it is necessary to understand how each component of the system interacts with the others.

Recognising a multiprocessor architecture requires first having a firm grasp on how the several processors present in a system interact with and pass information to one another.
