What is a parallel calculation?

parallel computer technology occurs when the computer performs more than one task simultaneously. This technique can allow computers to work faster than do one thing at the same time, as well as a person with two free hands can carry more than a person with one free hand. Computer programs are traditionally designed in ways that do not necessarily allow parallel computer technology, but instead must be made one step by one. In order to calculate the program in this way, it must be designed to be divided into smaller tasks that can be performed individually. As an example of how parallel computer technology concerns an average person, many personal computers have more processing cores that allow them to process multiple tasks at the same time, instead of one task after another as with the only processor computer.

writing a computer program to be able to divide into separate tasks that haveIt is often harder to be made than to write one by one with a linear design. For computer programs that will be performed gradually, the first task usually determines information that is an integral part of the second task in the sequence. Without the first piece of information resulting from the first task, the second task may be unnecessary to perform. When writing a program to be divided into different parts, timing of things, so different parts of the program have the information they need when they need it and does not take decisions based on outdated information, can be a unique challenge. This concern is usually associated with the most common types of computer errors facing parallel computing programs.

The main advantage of parallel calculation is that programs can perform faster. If a computer hardware that performs a program using parallel calculations effective technology. As an analogy if one man can carry one box at a time and that CPU is a man, the program performsGradually, it could be able to carry one box at the same time. In parallel, the same program could be divided into two separate tasks, and if there are two processors that use it, both boxes carry at the same time. In this way it carries both boxes and completes its task faster.
