Question

How has the presence of multiple cores on the more recent computer systems affected the way you write software? Describe the techniques you use to take advantage of the additional cores and the degree to which you benefit from the more powerful multi-core systems and describe any problems you may have experienced with such systems.

Answer 1

1. Using multi core processor speed up the processes as the programme can run in parallel
2. A multi-core processor is a single computing component with two or more independent actual processing units , which are units that read and execute program instructions
3. They are mostly used in almost many domains like embedded systems networks business environment
4. .The instructions are ordinary CPU instructions but the multiple cores can run multiple instructions at the same time, increasing overall speed for programs amenable to parallel computing
5. A multi-core processor implements multiprocessing in a single physical package.

Problems

1. They require complex coordination of threads
2. They require complex debugging..it makes debugging very difficult
3. Developers programming in newer languages might find that their modern languages do not support multi-core functionality
