Parallel Computing for beginners!

What does it mean?

Well.... Wikipedia says:


Parallel computing is a form of computation in which many calculations are carried out simultaneously, operating on the principle that large problems can often be divided into smaller ones, which are then solved concurrently ('in parallel').


In simple words, parallel computing aims to optimize the execution time by dividing the task among multiple computers.


what kind of forms? there are several different forms of parallel computing, for example: bit-level, instruction level, data and task parallelism.. Parallelism has been employed for many years , mainly in high-performance computing, but interest in it has grown lately due to the physical constraints preventing frequency scaling.

Work with others computers could be better, but in some cases this kind of computing worsens the job. Imagine that you want to start a newspaper, what happens first? you have to designate specific tasks for specific persons. So, work with more people give better results.

Now, focus your attention on the case of solving combined operations with friends and imagine the time doing it by yourself. It is worst working with other persons that doing it by yourself because takes more time asking for an answer that operating by yourself.


These are simple examples special for beginners like me.
