I'm trying to find information for why multi core processor programming is harder than single core processor programming.
I know google is my friend, but it has let me down lol

There are 4 various model used in software develop ment,system development lifecyclemodel,prototyping model,rapid application development model,component Component Assembly Model.software development also depended in market reserch,analyzing the problem,implementation of software,testing software,and client requirement.

As computing requirements persist to put rising demand on the requirement for quicker and more powerful computer hardware, the dual-core processors have become approximately common place in the majority computers. Actually, a few chip makers such as AMD and Intel have already released quad core processors and further than. One group of researchers is even looking at the possibility of making a single processor containing over 100 cores.
