Parallel processing uses multiple microprocessors to complete tasks simultaneously, resulting in faster results. It is useful for complex calculations and can be applied in various fields such as weather modeling and virtual reality. The success of parallel computing requires structured tasks and maintained task sequences.
Parallel processing is the simultaneous processing of the same task on two or more microprocessors in order to achieve faster results. Computer resources can include a single computer with multiple processors, or a number of computers connected by a network, or a combination of both. Processors access data through shared memory. Some supercomputer parallel processing systems have hundreds of thousands of microprocessors.
With the help of parallel processing, multiple calculations can be performed simultaneously, reducing the time needed to complete a project. It is particularly useful in projects that require complex calculations, such as weather modeling and digital special effects. Let’s take a real example to understand the effectiveness of this type of processing.
If a busy mall has only one checkout counter, customers will form a single queue and wait their turn. If there are two cash counters, the business can be effectively split. Customers will form two queues and will be served twice as fast. This is one case where parallel processing is an effective solution.
With the help of parallel processing, it is possible to effectively solve highly complex scientific problems that would otherwise be extremely difficult to solve. Parallel computing can be effectively used for tasks that involve a large number of calculations, are time-constrained, and can be broken up into a number of smaller tasks.
Parallel processing is particularly beneficial in areas such as weather and climate, chemical and nuclear reactions, petroleum exploration, seismic data measurement, space technology, electronic circuits, human genome, medicine, graphics advanced and virtual reality and manufacturing processes.
In all likelihood, parallelism is the future of computing. Overall, the successful implementation of parallel computing comes with two challenges:
The tasks should be structured in such a way that they can be performed simultaneously
The sequence of tasks that have to be performed one after another should be maintained
